The Technical SEO Checklist to Rank Higher in 2026
A no-fluff technical SEO checklist from a working SEO agency in Tunisia: Core Web Vitals, structured data, crawlability and more.
Great content won't rank if search engines can't crawl, understand and trust your site. As an SEO agency in Tunisia, technical SEO is where we start every engagement. Here's the checklist we actually use.
1. Core Web Vitals
Google ranks fast sites higher. Aim for:
- LCP under 2.5s
- INP under 200ms
- CLS under 0.1
Server rendering, image optimization and lazy-loading heavy assets (like 3D) get you there.
2. Crawlability & indexing
- A clean
robots.txtthat doesn't block important pages. - An auto-generated
sitemap.xml. - Canonical URLs on every page to avoid duplicate content.
3. Structured data
Schema.org markup helps search engines understand your content and unlocks rich results. At minimum, add:
OrganizationandWebSiteLocalBusinessif you serve a regionBreadcrumbListandArticlewhere relevant
4. Semantic HTML
One <h1> per page, a logical heading hierarchy, descriptive link text and proper landmarks. Accessibility and SEO are two sides of the same coin.
5. Metadata hygiene
Unique, compelling titles and descriptions. OpenGraph and Twitter cards so your links look great when shared.
The compounding payoff
Technical SEO isn't a one-time fix — it's a foundation. Get it right and every piece of content you publish afterwards ranks faster and higher. Want an audit of your site? Reach out.
