Technical SEO Checklist: 12 Fixes That Actually Move Rankings

Most SEO advice obsesses over content while sites quietly suffer technical problems that cap what any content can achieve. When we audit websites, the same twelve issues appear again and again — and fixing them often lifts rankings within weeks, no new content required.

Crawling and indexation

• 1. Pages accidentally blocked by noindex tags or robots.txt — shockingly common after site migrations.
• 2. Canonical tags pointing to the wrong URLs, telling Google your pages are duplicates.
• 3. Redirect chains and loops wasting crawl budget and diluting link equity.
• 4. Orphan pages with no internal links — Google rarely ranks pages your own site doesn't vouch for.
• 5. XML sitemaps listing deleted, redirected, or noindexed URLs.

Performance and rendering

• 6. Failing Core Web Vitals — LCP over 2.5s or CLS from layout shifts directly suppress rankings.
• 7. JavaScript-rendered content invisible to crawlers — critical for React sites without server rendering.
• 8. Unoptimized images dragging mobile performance, where most searches happen.

Structure and signals

• 9. Missing structured data — FAQ, product, review, and organization schema power rich results that lift click-through rates.
• 10. Weak internal linking that fails to concentrate authority on money pages.
• 11. Duplicate title tags and meta descriptions across templated pages.
• 12. Missing or misconfigured hreflang on international sites, splitting rankings between regions.

The advantage of technical SEO: unlike content strategy, these are deterministic fixes with measurable outcomes. Our technical SEO audits identify exactly which of these affect your site — and because we are developers, we implement the fixes rather than mailing you a PDF.
