🛠️ How to Use This Checklist
Run your site through PageSpeed Insights and Google Search Console first. Then work through these 25 fixes in priority order.
Section 1: Core Web Vitals (3 Critical Fixes)
Fix 1 — Largest Contentful Paint (LCP) Under 2.5 Seconds
LCP measures how fast your main content loads. Over 2.5s = Google ranking penalty.
- Compress all images to WebP format (use Squoosh.app)
- Add
fetchpriority="high"to your hero image - Enable browser caching on your server
- Use a CDN (Cloudflare free plan works well)
Fix 2 — Cumulative Layout Shift (CLS) Under 0.1
- Always set width and height attributes on every image tag
- Reserve space for ads and embeds with CSS
aspect-ratio - Avoid injecting content above existing page content
Fix 3 — Interaction to Next Paint (INP) Under 200ms
- Defer non-critical JavaScript (add
deferattribute) - Remove unused CSS and JS plugins
- Minify CSS, JS, and HTML files
Section 2: Mobile SEO (4 Fixes)
Google uses mobile-first indexing — it ranks your mobile version. With 70%+ of Indian searches on mobile, this is non-negotiable.
Viewport Meta Tag
Every page must have: <meta name="viewport" content="width=device-width, initial-scale=1.0">
Tap Target Size
All buttons and links must be at least 44×44 pixels. Test using Chrome DevTools mobile emulation.
No Horizontal Scrolling
Test every page at 375px width. Any overflow:hidden missing on body? Any fixed-width elements?
Font Size
Body text minimum 16px. Smaller text forces users to zoom = bad UX signal to Google.
Section 3: Crawlability (5 Fixes)
XML Sitemap Submitted
Create sitemap.xml with all important pages. Submit in Google Search Console → Sitemaps.
Fix 404 Errors
Check Search Console → Coverage → Not Found. Fix with 301 redirects to the correct page.
robots.txt Check
Ensure you're not accidentally blocking important pages. Check: yoursite.com/robots.txt
Fix Redirect Chains
A→B→C is bad. Fix to A→C directly. Use Screaming Frog to find all chains.
Canonical Tags
Add <link rel="canonical" href="..."> to every page to prevent duplicate content issues.
Section 4: On-Page Technical (6 Fixes)
- Fix 13: Title tags — Unique, 50-60 chars, keyword in first 3 words
- Fix 14: Meta descriptions — Unique, 120-160 chars, includes keyword + CTA
- Fix 15: One H1 per page — Never zero, never two H1s
- Fix 16: Image alt text — Every image needs descriptive alt text with keywords where natural
- Fix 17: Internal links — Every important page should have 5+ internal links pointing to it
- Fix 18: Hreflang — If targeting India specifically:
<link rel="alternate" hreflang="en-IN">
Section 5: Schema Markup (4 Fixes)
⭐ High Impact
Schema markup can generate rich results — star ratings, FAQs, breadcrumbs in Google — that dramatically increase click-through rates without changing your rankings.
- Fix 19: LocalBusiness schema — Name, address, phone, hours, coordinates
- Fix 20: FAQPage schema — Shows expandable Q&As in Google search results
- Fix 21: BreadcrumbList schema — Shows site structure in search results
- Fix 22: Article/BlogPosting schema — For blog posts — datePublished, author

HTTPS page loading HTTP resources? Check Chrome DevTools Console for warnings.
Core Update Recovery Check
Check your Search Console Performance report for traffic drops coinciding with Google Core Updates (published on Google Search Central blog).
