The Foundation of Search
You can have the best content in the world, but if search engines can't crawl or index your site, you won't rank. Technical SEO is the infrastructure that supports your content strategy.
In 2025, technical SEO has evolved beyond just sitemaps and robots.txt. It now encompasses Core Web Vitals, JavaScript rendering and schema markup for AI agents.
The 2025 Technical SEO Checklist
1. Crawlability and Indexability
- Robots.txt: Ensure you're not blocking critical resources.
- Sitemap.xml: Submit a clean, up-to-date sitemap to GSC and Bing Webmaster Tools.
- Canonical Tags: Prevent duplicate content issues by defining the preferred version of each page.
- Status Codes: Fix 404 errors and minimize 301 redirect chains.
2. Site Performance (Core Web Vitals)
Google's Core Web Vitals are a direct ranking factor. Aim for:
- LCP (Largest Contentful Paint): < 2.5 seconds
- INP (Interaction to Next Paint): < 200 milliseconds
- CLS (Cumulative Layout Shift): < 0.1
3. Mobile-First Indexing
Google predominantly uses the mobile version of the content for indexing and ranking. Ensure your mobile site is fully responsive and has the same content as desktop.
4. Structured Data (Schema Markup)
Help search engines understand your content with JSON-LD schema:
- Organization: Logo, social profiles, contact info
- Article: Headline, image, date published
- Product: Price, availability, ratings
- FAQ: Questions and answers
5. JavaScript SEO
If you're using React, Vue, or Angular, ensure you're using Server-Side Rendering (SSR) or Static Site Generation (SSG). Client-side rendering can cause indexing delays.
