Advanced Technical SEO Complete Checklist

1. Use HTTPS

What & Why:
HTTPS secures your website by encrypting data between the user and your site. It’s a ranking signal and boosts trust.

How to Implement:

      Buy or get a free SSL certificate (e.g., Let’s Encrypt).

      Configure your server to redirect HTTP to HTTPS.

      Check for non-secure content using tools like Semrush Site Audit.

2. Find & Fix Duplicate Content Issues

What & Why:
Duplicate content (same content across pages) confuses search engines, causing issues with ranking and crawl budget.

How to Fix:

      Use canonical tags to show which version is the main one.

      Use 301 redirects if the duplicate page shouldn’t exist.

      Audit your site using Semrush for “Duplicate Content” errors.

3. Make Sure Only One Version of Your Website Is Accessible

What & Why:
 If both www.example.com and example.com are accessible, it causes duplicate content and weakens link equity.

Fix It:

      Pick one version (www or non-www).

      Redirect the other version using a 301 redirect.

4. Improve Your Page Speed

Why It Matters:
 Speed is a ranking factor. Faster websites reduce bounce rates and improve user experience.

How:

      Compress images using tools like TinyPNG or ShortPixel.

      Use CDNs (like Cloudflare).

      Minify CSS, JavaScript, and HTML files.

5. Ensure Your Website Is Mobile-Friendly

Why:
Google uses mobile-first indexing. If your mobile version is poor, your rankings drop.

Checklist:

      Responsive design.

      Easy-to-read text.

      Clickable buttons spaced out properly.

      Fast load speed on mobile.

6. Use Breadcrumb Navigation

Why:
Breadcrumbs help both users and search engines understand page hierarchy. They improve UX and internal linking.

How:
Implement structured markup for breadcrumbs using schema.

7. Use Pagination

What It Is:
If you split long lists into multiple pages, use rel="next" and rel="prev" to tell Google they’re part of a series.

8. Review Your Robots.txt File

Why:
 Controls which parts of your site search engines can crawl.

To-Do:

      Allow important pages.

      Block internal or sensitive pages (e.g., /cart/, /wp-admin/).

      Check it in https://yoursite.com/robots.txt

9. Implement Structured Data

Why:
 It gives search engines detailed information (like product ratings, events). It can generate rich snippets on SERPs.

How:

      Use schema.org vocabulary.

      Validate with Google’s Rich Results Test.

      Use JSON-LD format.

10. Find & Fix Broken Pages

Why:
404 pages harm UX and SEO, especially if they had backlinks.

Fixes:

      Reinstate removed content.

      Redirect to a relevant live page.

      Audit using Semrush: search for “4xx” in issues tab.

11. Optimize for Core Web Vitals

Metrics:

      LCP (Largest Contentful Paint): ≤ 2.5s

      FID (First Input Delay): ≤ 100ms

      CLS (Cumulative Layout Shift): ≤ 0.1

Use Tools:

      Google Search Console (Core Web Vitals report)

      PageSpeed Insights

      Semrush Core Web Vitals report

12. Use Hreflang for Multilingual Content

Why:
 Helps Google serve the correct language or regional version of your page.

Example Tag:

html

<link rel="alternate" hreflang="es" href="https://yourwebsite.com/es/" />

Use Cases:

      Different language versions.

      Same language, different region (e.g., en-US vs en-GB).

13. Stay on Top of SEO Issues

Why:
SEO isn’t a one-time job. You must monitor for new technical issues as the site evolves.

Tools:

      Semrush Site Audit (monitors 140+ issues).

      Regular audits uncover issues like redirect chains, broken links, missing metadata, etc.

14. Redirect or Replace Broken Internal Links

Why:
They lead to 404 pages, breaking user flow and harming crawlability.

Fix:

      Use Semrush to locate broken internal links.

      Either fix the link or redirect it properly.

15. Fix 5XX Errors

What It Means:
 Server-side errors (like 500 Internal Server Error). These stop Google from crawling your content.

Solution:

      Monitor via Semrush or Search Console.

      Check hosting/server logs.

16. Fix Redirect Chains & Loops

Why:
Too many redirects slow things down. Loops can trap crawlers.

Fix:

      Update links to point directly to final URL.

      Limit to one 301 redirect whenever possible.

17. Use an XML Sitemap

Purpose:
 Helps search engines find and crawl all important URLs.

Best Practices:

      Submit via Google Search Console.

plaintext

site:yourdomain.com/page-name

If not indexed:

      Remove noindex tag if present.

      Build internal links to it.

What:
Pages with no internal links pointing to them. Google may never discover them.

Solution:

      Use Semrush to find orphan pages.

      Link to them from relevant internal pages.

21. Minimize Click Depth

Why:
Pages 4+ clicks from homepage are crawled less and seen as less important.

Fix:

      Link key pages from homepage or hubs.

      Flatten site structure.

22. Check URL Structure

Best Practices:

      Keep it short and keyword-rich.

      Use hyphens (-) not underscores.

      Avoid unnecessary parameters.

23. Remove Unnecessary Third-Party Scripts

Example Tag:

html

<link rel="canonical" href="https://example.com/page/" />

In Details

SECTION 1: Make Sure Your Website Uses HTTPS

What is HTTPS?

HTTPS (HyperText Transfer Protocol Secure) encrypts the connection between your website and your visitor’s browser.

Why does it matter?

      Google confirmed HTTPS is a ranking factor.

      Protects user data (forms, passwords).

      Prevents hackers from intercepting info.

How to set it up:

  1. Get an SSL certificate (free from Let’s Encrypt or paid via your host).

  2. Force all URLs to redirect from HTTP to HTTPS.

  3. Update your internal links and canonical tags to reflect HTTPS.

  4. Test security with tools like SSL Labs.

SECTION 2: Find and Fix Duplicate Content

What is duplicate content?

Two or more pages on your site have identical or very similar content.

Why it matters:

      Confuses Google: Which one to rank?

      Splits SEO power across pages.

      Wastes crawl budget.

How to fix:

      Use canonical tags to point Google to the original version.

      Use 301 redirects to merge duplicates.

      Consolidate thin pages into one strong resource.

      Avoid printing or URL parameters creating copies (?ref, ?source).

SECTION 3: Ensure Only One Version of Your Website Is Accessible

Problem:

Your website may be accessible at multiple versions:

      http://example.com

      http://www.example.com

      https://example.com

      https://www.example.com

Why it matters:

      Google treats each as a separate page = duplicate content.

      Link equity gets split.

Fix:

      Choose one (usually https://www.example.com).

      Set a 301 redirect from all other versions to the preferred one.

      Set your preferred domain in Google Search Console.

SECTION 4: Improve Your Page Speed

Why speed matters:

      Google ranks faster pages higher.

      Visitors will leave if your site is slow.

      Affects Core Web Vitals.

How to improve:

  1. Compress images with TinyPNG, ShortPixel.

  2. Minify CSS/JS/HTML (remove spaces and comments).

  3. Use lazy loading for images.

  4. Host on fast servers or use CDNs (Cloudflare, BunnyCDN).

  5. Use caching (e.g. WP Rocket, Litespeed).

Check with PageSpeed Insights

SECTION 5: Ensure Mobile-Friendliness

What’s mobile-first indexing?

Google now uses the mobile version of your site as the primary version for indexing and ranking.

Why it matters:

      Over 60% of users browse on mobile.

      Mobile-unfriendly sites drop in rankings.

Checklist:

      Responsive design (adapts to screen size).

      Avoid tiny text or too-close buttons.

      Fast load times on mobile.

      Use Google’s Mobile-Friendly Test.

SECTION 6: Use Breadcrumb Navigation

What are breadcrumbs?

A secondary navigation system showing where the user is:

Home > Blog > SEO Tips > Internal Linking

Benefits:

      Helps users navigate.

      Helps Google understand your site structure.

      Appears in rich results.

How to implement:

      Add visible breadcrumbs using HTML/CSS.

      Add schema markup for BreadcrumbList.

SECTION 7: Use Pagination Properly

What is pagination?

When long content or product listings are split across multiple pages:

      Page 1 → Page 2 → Page 3

Tips:

      Use rel="next" and rel="prev" in HTML.

      Avoid canonicalizing every page to page 1.

      Ensure links to all pages are crawlable.

SECTION 8: Review Your Robots.txt File

What is it?

A file at yourdomain.com/robots.txt that tells search engines which pages to crawl or ignore.

How to use:

      Allow crawlers to reach important pages.

      Disallow internal or private areas:

plaintext

Disallow: /checkout/

Disallow: /admin/

      Test in Google Search Console → robots.txt tester

      Products

      Reviews

      Events

      FAQs

Why it matters:

      Enables rich snippets (stars, images, FAQ drop-downs).

      Improves CTR and rankings.

Use schema.org + JSON-LD format.

Example:

json

{

  "@context": "https://schema.org",

  "@type": "Product",

  "name": "Leather Wallet",

  "offers": {

    "@type": "Offer",

    "price": "45.00",

    "priceCurrency": "USD"

  }

}

SECTION 10: Find and Fix Broken Pages (404 Errors)

Why it matters:

      Users get frustrated.

      Google bots hit dead ends = crawl budget wasted.

How to fix:

      Use Semrush or Screaming Frog to find 404s.

      Redirect old URLs with 301s to relevant pages.

      Rebuild missing content if needed.

SECTION 11: Optimize for Core Web Vitals

What are they?

  1. LCP (Largest Contentful Paint) – How fast big elements load.

Fixes:

      Use lazy loading.

      Compress files.

      Reserve space for images (to reduce CLS).

      Avoid blocking JavaScript.

Test in PageSpeed Insights or Google Search Console.

SECTION 12: Use Hreflang Tags for Multilingual Sites

COMPLETE 9-STEP SEO AUDIT (by GotchSEO)

This complements the above and focuses on strategy:

  1. Define Strategic Objectives.

  2. Do Keyword Analysis (quality, intent, difficulty).

  3. Conduct Competitor Analysis.

  4. Review Technical SEO: speed, indexation, redirects, mobile.

  5. Page-Level Optimization.

  6. Content Quality Review.

  7. UX Signals (time on site, bounce, return visits).

  8. Link Profile Audit.

  9. Citation/NAP Review for Local SEO.

In Details

Step 1: Check Your Organic Traffic

Goal: Understand how much free (organic) traffic you’re getting from Google and which pages are performing best.

Why it's important:

      Shows your site’s current visibility in search results.

      Helps identify which content is working — and what’s not.

      Acts as a starting benchmark for your SEO audit.

How to do it:

  1. Open Google Analytics:

      Go to Reports > Acquisition > Traffic Acquisition.

      Filter by “Organic Search” as the traffic source.

      Choose a longer time frame (last 3–6 months) to view performance trends.

  1. Open Google Search Console:

      Go to Performance > Pages.

      See which URLs get the most clicks.

      Look for pages that:

      Used to get more traffic.

      Are ranking but not in the top 5 (yet).

Example:

If /blog/seo-tips used to get 1,000 clicks/month and now only gets 300, that’s a declining performer you should investigate.

The point isn’t to panic — it's to identify top performers and low-hanging fruit for improvement.

Step 2: Run a Full Site Crawl

Goal: Analyze your site’s structure and technical issues at scale.

Why it's important:

      Uncovers SEO blockers like broken links, missing titles, slow pages, and more.

      Gives a site-wide health report.

Tools you can use:

      Screaming Frog SEO Spider (free for 500 URLs)

      Semrush Site Audit (100 free URLs or 14-day Pro trial)

How to do it:

  1. Enter your domain.

  2. Let the tool scan all your site’s pages.

  3. Review data like:

      Title & meta tag issues.

      Broken internal/external links.

      Thin or duplicate content.

      Structured data errors.

Example:

Screaming Frog shows that /services/design.html is a 404 error — fix this by redirecting or restoring the page.

This crawl gives you a map of SEO problems to work through efficiently.

Step 3: Improve Your On-Page SEO

Goal: Optimize individual pages so that Google understands what each is about and how it serves the user.

Why it's important:

      On-page SEO directly affects rankings.

      Helps target specific keywords effectively.

Focus on your top 5 pages:

      High-potential (ranking but not in top 3).

      Important to your business (like service/product pages).

5 Key Actions:

  1. Title Tag – Include main keyword.

      Example: “Best SEO Tools for 2024” not “Home”

  1. Meta Description – Include keyword + compelling reason to click.

      Example: “Explore the top SEO tools to boost traffic in 2024.”

  1. Header Tags (H1–H3) – Organize content clearly.

  2. First 100 Words – Use your main keyword naturally.

  3. Image Alt Text – Use keyword in the first image’s alt attribute.

Example:

If the page is about “cheap smartphones in UAE,” your H1 might be:

“Top 10 Cheap Smartphones You Can Buy in the UAE (2024 Guide)”
 And your first sentence might be:
 “Looking for an affordable smartphone in the UAE? Here are our top picks…”

You don’t need to over-optimize — just make your content clear, focused, and helpful.

Step 4: Maximize Your Internal Linking

Goal: Guide users and search engines to your most valuable pages.

Why it's important:

      Passes link equity (ranking power).

      Improves crawlability and user navigation.

      Reduces orphan pages (pages with no internal links).

Best practices:

  1. Use contextual anchor text.

      Example: From a blog post on marketing tools, link like this:
 “For SEO, we use a range of [keyword research tools].”

  1. Link to high-priority pages often.

  2. Keep crawl depth low (within 3 clicks from homepage).

Example:

If you have a post on “Image SEO” and another post on “SEO basics,” mention the Image SEO post with a link:

“Once your content is ready, don’t forget to optimize images. Here’s a guide on [Image SEO best practices].”

Internal links are simple to add but powerful for SEO when done right.

Step 5: Optimize for UX Signals

Goal: Improve how real users interact with your content.

Why it's important:

      Google’s RankBrain and user metrics (like click-through rate, bounce rate, time on site) influence rankings.

      Content must match search intent — not just contain keywords.

What is UX Optimization?

      Making your content easy to read and satisfying.

      Making sure people stay on your site and don’t bounce.

Key areas to improve:

  1. Satisfy Search Intent
     If the keyword is “how to run Facebook ads,” users expect a step-by-step guide, not just tips or history.

  2. Update Outdated Content
     Replace old screenshots, add recent stats.

  3. Add visuals, examples, and summaries
     Use images, tables, and actionable examples to break up text.

  4. Improve mobile usability
     Use responsive design and large buttons.

Case Example:

An SEO blog post on “SEO Campaigns” wasn’t ranking. After updating it with:

      A clear step-by-step format.

      Updated images.

      Better alignment with search intent...

… the post went from rank #15 to #1 in Google, even earning the featured snippet.

COMPLETE CHECKLIST OF TECHNICAL SEO TIPS (Explained in Depth)

1. Use Screaming Frog to Crawl Rendered JavaScript Content

      Why it matters: Google can now index JS-rendered pages, but many crawlers can't see dynamic elements.

      What to do:

      Set Screaming Frog’s rendering mode to JavaScript rendering.

      Compare the HTML vs rendered DOM to ensure Google sees full content.

Example: Your product descriptions are loaded via JavaScript — Screaming Frog in standard mode won’t see them, but Google can. You need to verify rendered output.

2. Integrate Custom Extraction in Screaming Frog

      Why it matters: Sometimes you want to pull data beyond titles and headings — like schema types, custom attributes, or JS-injected content.

      What to do:

      Use Custom Extraction to collect structured data or meta info like productPrice, JSON-LD blocks, etc.

Example: Extract all @type values from your structured data to verify proper use of Product, Article, or Breadcrumb.

3. Use Log File Analysis to See What Googlebot Crawls

      Why it matters: Log files tell you exactly what Googlebot accessed, when, and how often.

      How:

      Use tools like Screaming Frog’s Log Analyzer.

      Identify crawl waste (unimportant URLs being hit) or neglected pages.

Example: If Googlebot keeps crawling filters like /?color=blue, you might need to block them in robots.txt.

4. Crawl Budget Optimization: Focus on High-ROI Pages

      Why it matters: On large sites, Google won’t crawl everything often. Prioritize important content.

Tips:

      Reduce crawlable junk (faceted nav, empty category pages).

      Use internal linking to boost crawl frequency of money pages.

      Block or noindex low-value templates.

5. Avoid Overloading Google with Useless Variants

      Why it matters: E-commerce sites generate tons of similar URLs (e.g. size, color, filters).

      Fixes:

      Canonicalize product variants to main pages.

      Disallow filters in robots.txt.

      Use parameter handling in GSC.

Example: /shoes?color=red and /shoes?color=blue → both should point to /shoes via canonical tag.

6. Test How Google Renders Your Page with Chrome Dev Tools

      Why it matters: JavaScript-based websites may look fine to users but appear broken to bots.

How:

      Use “Inspect Element” → “View Rendered Source” or Google’s Mobile-Friendly Test and URL Inspection Tool.

      Confirm that important content and links appear in the DOM.

7. Audit Canonical Tags Across Product/Variant Pages

      Why: Conflicting canonical tags confuse search engines and can lead to de-indexing important pages.

Good Setup:

      Main product page → canonical to itself

      Variant pages → canonical to the main page

8. Use Internal Site Search Data for SEO

      Why it matters: What users search on your site = what they actually want.

      Action:

      Review internal search queries.

      Use findings to create content, improve nav, or optimize existing pages.

Example: Many people search "refund policy" → create a dedicated FAQ page with strong internal linking.

9. Monitor Soft 404s and Noindex Tags in GSC

      Why it matters: Google may see blank or error-prone pages as "soft 404s" — and drop them from the index.

Fix:

      Use GSC’s Coverage > Excluded > Soft 404 report.

      Add real content or proper redirects.

10. Indexing Troubleshooting: Use Coverage + Render Tools Together

      Steps:

1.     Use GSC’s Index > Coverage to see excluded pages.

2.     Use Inspect URL tool to see how Google renders that page.

3.     Fix rendering issues, canonical conflicts, or noindex tags.

11. Use Parameter Tools in GSC for Crawl Control

      What: You can tell Google how to handle URLs like ?sort=price or ?filter=lowstock.

      Why: Prevents crawl budget being wasted on duplicate content.

Pro Tip: Combine with robots.txt and canonical tags for best results.

12. Core Web Vitals Fixes: Render-Blocking Resources

      Issue: CSS or JavaScript that blocks rendering hurts your LCP (Largest Contentful Paint).

      Fix:

      Inline critical CSS.

      Use async or defer for non-critical JS.

      Load fonts early with preload.

13. Use the Right Status Codes

      Avoid:

      Returning 200 for error pages (use 404 or 410).

      Returning 302 instead of 301 for permanent redirects.

      Tools: Screaming Frog, Chrome Dev Tools

14. Prioritize Mobile Rendering Issues

      Why: Google uses mobile-first indexing.

      Use the Mobile Usability Report in GSC.

      Check font size, tap targets, horizontal scrolling.

Example: If buttons are too close or the layout breaks, fix with responsive design CSS or mobile-friendly layout adjustments.

15. Use Lazy Loading Properly

      Why: Improves performance by loading images only when needed.

      Caution: Ensure that lazy-loaded content still appears in rendered HTML (or Google may miss it).

16. Avoid JavaScript-Only Navigation

      Issue: If navigation links are built entirely with JS, Google might not follow them.

Fix:

      Use <a href="..."> tags with real URLs.

      Ensure links appear in rendered HTML.

17. Optimize Pagination with rel="next" and rel="prev"

      Why: Helps Google understand paginated series (e.g. product lists, blogs).

      Though deprecated by Google, still used by other engines and helps clarity.

18. Don’t Over-Rely on XML Sitemaps

      Why: A sitemap is NOT a guarantee of indexing.

      Internal links carry more weight than sitemap inclusion.

Fix orphan pages by linking them internally, not just adding to a sitemap.

19. Use Structured Data Correctly

      What: Schema for products, breadcrumbs, FAQs, etc.

      Tools: Google Rich Results Test, Schema.org validator

Mistakes like wrong data types or misplaced fields can cause eligibility failures in SERPs.

20. JavaScript SEO Checklist

      Pre-render dynamic content for bots (via SSR or dynamic rendering).

      Ensure crawlable links.

      Reduce reliance on JS for critical content.

      Avoid JS errors that block rendering.

Final Advice from Experts:

      Don’t blindly trust “indexed” = “optimized” — rendering issues may block content.

      Automate routine crawls with Screaming Frog or Sitebulb.

      Log analysis > crawl simulation for large/enterprise sites.

      Every tech fix should tie back to crawlability, indexation, and SERP performance.

DETAILED CHECKLIST WITH EXPLANATIONS

1. Crawl Rendered JavaScript Pages with Screaming Frog

What’s the Problem?

Many websites load content using JavaScript (e.g. React, Vue, Angular). Most traditional crawlers (like Screaming Frog in default mode) only see the HTML, not what the page looks like after JS is rendered.

What to Do:

      Open Screaming Frog.

      Set Rendering to JavaScript Mode in “Configuration > Spider > Rendering”.

      Crawl your site.

Example:

You visit a product page. The description looks fine in your browser. But Screaming Frog shows it’s missing — why? Because that description is loaded after the page loads (with JavaScript). You wouldn’t know this unless you crawl with JS rendering turned on.

Why It Matters:

If Google can’t render your JS, it may not index key content — meaning lost rankings.

2. Use Custom Extraction in Screaming Frog

What is Custom Extraction?

This feature lets you pull out specific data like schema, JSON-LD, Open Graph tags, or any HTML element from your pages.

How to Use:

      In Screaming Frog > “Configuration > Custom > Extraction”

      Use XPath or CSS selectors to extract things like:

      @type from schema.org

      meta[property="og:title"]

      Product prices from HTML spans

Example:

You want to check that all your product pages use @type: Product in structured data. Instead of checking one-by-one, custom extraction lets you collect them all at once.

Why It Matters:

It saves hours of manual checking and ensures data consistency across your site.

3. Use Log File Analysis to Understand Crawl Behavior

What is a Log File?

A log file records every time Googlebot (or a user) visits a page on your site. It shows:

      IP address

      Date/time

      Page URL

      User-agent (Googlebot, Bingbot, etc.)

What You Learn:

      Which pages Google crawls often (high importance).

      Which pages Google ignores (potential problems).

      If it’s crawling useless URLs (like search filters).

Tools:

      Screaming Frog Log File Analyzer

      JetOctopus

      Raw log access via your server or host

Example:

If you find Googlebot crawls /category?page=99 every day but skips /best-sellers, you know to adjust your internal linking or robots.txt.

4. Optimize Crawl Budget for Important Pages

What’s Crawl Budget?

The number of pages Google is willing to crawl on your site per day.

If you have a large site, Google can’t crawl everything at once — it prioritizes pages based on internal links, update frequency, and importance.

What to Do:

      Block non-important URLs (/filters, /?sort=price) in robots.txt.

      Use canonicals and parameter controls.

      Improve internal links to important content.

Example:

E-commerce sites often generate 1000s of filter combinations — /shoes?color=blue&size=9. These can eat crawl budget unless blocked.

5. Canonicalize Duplicate Pages Properly

What’s a Canonical Tag?

It tells Google: “This is the main version of the page.”

Use Case:

Product variants (color, size, etc.) often create duplicate content. Canonical tags solve that by pointing all variants to the main product URL.

html

<link rel="canonical" href="https://example.com/product-name" />

Example:

      /product?color=red

      /product?color=blue
 Both should have a canonical tag pointing to /product.

6. Test JavaScript Rendering with Google Tools

Tools to Use:

      Google Search Console → URL Inspection Tool

      Mobile-Friendly Test – Shows how Google renders your site

What to Look For:

      Is important content visible?

      Are key links in the rendered HTML?

Google may not wait long to render your JS — if it takes too long or errors out, your content won’t be seen or indexed.

7. Use Internal Site Search Data for Content Ideas

What is Internal Site Search?

What people search inside your website (via your own search box).

Why It’s a Goldmine:

It tells you what real users are looking for, in their own words.

Example:

If many users type “return policy” into your search box, it means they:

      Don’t see a return policy link easily

      Want that info now

Fix:

      Create a clear Return Policy page

      Add internal links from product pages

8. Fix Soft 404s and Misconfigured Status Codes

What’s a Soft 404?

A page looks like a 404 (no content) but sends a 200 OK status — so Google thinks it's valid and wastes indexation space.

Fix:

      If page is dead → return 404 or 410 status.

      If page is real → add content and fix issues.

Tools:

      GSC → Coverage → Excluded → Soft 404

      Screaming Frog → Check status codes vs content

9. Use Google’s Parameter Handling Tool

Where:

Google Search Console → Legacy Tools → URL Parameters

Why:

Tell Google how to treat things like:

      ?color=blue

      ?sort=high-to-low

Set unnecessary parameters to “No URLs”.

10. Check Core Web Vitals (CWV)

Metrics:

  1. LCP – Largest element should load < 2.5s

  2. FID – Input response < 100ms

  3. CLS – Avoid layout shifts (target < 0.1)

Fix Tips:

      Use lazy loading

      Preload fonts

      Defer JS

Use PageSpeed Insights and Search Console’s CWV report.

11. Use Correct Redirects (301 vs 302)

Difference:

      301 = Permanent redirect → Passes SEO value

      302 = Temporary → May NOT pass link equity

Always use 301 for permanent changes:

http

301 Moved Permanently

12. Lazy Load Correctly

Why:

Speeds up initial load by loading images only when needed.

Warning:

Make sure Google can see lazy-loaded images in the rendered HTML. Use IntersectionObserver or <img loading="lazy"> properly.

13. Avoid JavaScript-only Navigation

Why It’s Bad:

If your nav is JS-generated, Google might not find your links.

Use real <a href="..."> tags in the HTML.

Make sure links appear in:

      Source code

      Rendered DOM

14. Don’t Rely Solely on XML Sitemaps

Sitemaps help discovery, but if you have orphan pages (no internal links), they may still not rank.

Internal links > Sitemaps

15. Monitor Indexation Health in Google Search Console

Check:

      Pages marked “Crawled - currently not indexed”

      “Discovered – not indexed”

      “Excluded by noindex tag”

Fix by:

      Improving content

      Removing noindex

      Increasing internal links

FINAL ADVICE FROM SEO EXPERTS

      Always render what Google sees — don’t assume.

      Use Screaming Frog weekly for internal audits.

      Prioritize page performance and crawl efficiency.

      Clean up legacy issues — old pages, thin content, parameter noise.
