Technical SEO Checklist: 25 Fixes That Boost Rankings Fast

A well-written page that Google can't crawl ranks nowhere. Technical SEO is the scaffolding that makes everything else work. These 25 checks are ordered by the frequency with which they cause real ranking problems on real sites.

Crawlability and Indexation

Your first job is ensuring Google can find and read your pages. Everything else is secondary.

1. Robots.txt audit. Open yoursite.com/robots.txt. Confirm it doesn't disallow / or any directory containing your key pages. A misconfigured robots.txt is one of the most common causes of sudden traffic drops after migrations.

2. XML sitemap submission. Submit your sitemap in Google Search Console under Indexing > Sitemaps. Verify it contains only canonical, indexable URLs — no paginated URLs with ?page=2 parameters unless they're your intended canonical.

3. Crawl budget optimisation. If your site has more than 1,000 pages, Google won't crawl all of them on every pass. Use the URL inspection tool in GSC to identify pages being crawled versus indexed. Noindex paginated filter pages, tag archives, and search result pages that carry no unique content.

4. Canonical tag consistency. Every page must either declare itself as canonical or point to its canonical version. Duplicate content — identical pages served at multiple URLs — splits PageRank and confuses crawlers. Common culprits: HTTP versus HTTPS, www versus non-www, trailing slash versus no trailing slash.

5. Redirect chains. A 301 redirect loses a small percentage of PageRank with each hop. Three redirects in a chain means three losses. Audit all redirects using Screaming Frog. Flatten any chain longer than one hop.

6. Broken internal links. Every 404 encountered by a crawler wastes crawl budget. Run a monthly crawl and fix all internal links pointing to 404 pages. Screaming Frog free version handles up to 500 URLs.

7. Orphan pages. Pages with zero internal links are effectively invisible to crawlers. Export all your published URLs and cross-reference against your internal link report. Any page with no inbound internal links needs one added from a relevant parent page.

Performance and Core Web Vitals

8. LCP under 2.5 seconds. Largest Contentful Paint is Google's primary performance metric for user experience. The most common fix: serve your hero image in WebP format, add fetchpriority="high" to the LCP image element, and remove render-blocking scripts above the fold.

9. CLS under 0.1. Cumulative Layout Shift penalises pages where content jumps as the page loads. Specify explicit width and height attributes on all images and iframes. Reserve space for ads and dynamic content with CSS.

10. TTFB optimisation. Time to First Byte above 800ms indicates a server-side problem — slow database queries, no caching layer, or underpowered hosting. For Indian audiences, deploy on a Mumbai or Singapore data centre and use a CDN with Indian edge nodes.

Real-world impact: An e-commerce client in Pune with 4,200 product pages had an average LCP of 6.8 seconds on mobile. After switching to Next.js Image, enabling server-side caching, and moving to Cloudflare CDN, LCP dropped to 2.1 seconds. Organic traffic to product pages increased 34% over the next three months without any content changes.

Structured Data and Rich Results

11. Organisation schema on homepage. Declares your business name, logo, contact, and social profiles to Google's knowledge graph. Single implementation, lifetime benefit.

12. LocalBusiness schema on contact page. Critical for local SEO. Include address, phone, operating hours, and geo-coordinates.

13. FAQ schema on service pages. Each FAQ block adds visual real estate to your search result at no cost. Three to five questions per page is sufficient. Don't use FAQ schema on questions that aren't genuinely useful to searchers.

14. BreadcrumbList schema. Enables breadcrumb display in search results, which increases click-through rate by making the URL structure clearer.

15. Article schema on blog posts. Allows inclusion in Google Discover and enables author entity markup — important for E-E-A-T signals.

Mobile and International

16. Mobile-first rendering check. Google indexes the mobile version of your pages. Use Google's Mobile-Friendly Test to verify there are no blocked resources or viewport issues.

17. Tap target sizing. Interactive elements — buttons, links — must be at least 48x48px with 8px spacing between them on mobile. Small tap targets trigger a Page Experience penalty.

18. Hreflang for multilingual sites. If your site serves India and international markets in English, no hreflang is needed. If you serve multiple languages or regions with different content, implement hreflang correctly or risk canonicalisation errors.

On-Page Technical Elements

19. Title tag uniqueness. Every page must have a unique, descriptive title. Duplicate titles confuse Google about which page to rank for a given query.

20. Meta description uniqueness. Not a ranking factor, but directly affects click-through rate. Write unique meta descriptions for every page that appears in SERPs.

21. H1 uniqueness. One H1 per page. It should contain the primary keyword and match search intent.

22. Image alt text. Every image should have descriptive alt text. This serves accessibility and provides additional keyword context for image search.

23. Internal link anchor text diversity. Avoid using the exact same anchor text for every internal link to a page. Vary between the primary keyword, related phrases, and natural language variants.

24. No-index tag audit. Check that your staging environment is behind a robots.txt disallow, not a noindex tag that could be accidentally deployed to production. Check your page-level noindex tags quarterly.

25. HTTPS everywhere. Mixed content — HTTPS pages loading HTTP resources — triggers browser security warnings and suppresses rankings. Run a mixed content audit using Why No Padlock or Chrome DevTools.
