A comprehensive checklist to improve crawlability, indexability, and search rankings for your website.

Crawlability and Indexability

Ensure search engines can crawl and index your pages. Check robots.txt, XML sitemaps, canonical tags, and avoid duplicate content issues.

Core Web Vitals and Performance

Page speed, interactivity, and visual stability are ranking factors. Optimize images, reduce JavaScript, use caching, and improve server response times.

Mobile-First Experience

Google uses mobile-first indexing. Make sure your site is fully responsive, with fast mobile load times and touch-friendly navigation.

Structured Data and Schema Markup

Implement schema markup for articles, products, FAQs, and organizations to enhance search results with rich snippets and improve CTR.
