Technical SEO: A Checklist Before You Blame Content

7 min read

When traffic stalls, teams rewrite copy first. Often the issue is technical: pages blocked from indexing, duplicate titles, broken canonicals, or a sitemap that lies. Fix the plumbing, then optimize content.

Indexability basics

  • Confirm robots meta and X-Robots-Tag aren’t accidentally noindex on public pages.
  • Keep robots.txt from blocking CSS/JS that Google needs to render.
  • Canonical tags should point to the preferred URL — and match what you want indexed.
  • Soft-404s (200 responses with “not found” UI) confuse crawlers; return real 404/410.

Titles, descriptions, and headings

  • One unique <title> per indexable URL; keep important keywords early.
  • Meta descriptions aren’t a ranking factor, but they affect CTR — write them on purpose.
  • Use a single H1 that matches intent; don’t spam heading levels for style.
  • Template pages (blog, product, docs) need unique titles — check for duplicates across the site.

Sitemaps, links, and mobile

  • XML sitemap lists only canonical, indexable URLs and stays updated.
  • Internal links should reach important pages within a few clicks.
  • Mobile layout must be usable — Google indexes with a mobile user agent.
  • Fix redirect chains; prefer one clean hop to HTTPS + preferred host.

How to work the list

Audit top landing pages first, then templates that generate thousands of URLs. One broken product template beats twenty perfect blog posts. Re-crawl after deploys that touch head tags or routing.

Health Mesh’s SEO scans surface title/meta issues, structural problems, and related findings so you can fix templates instead of guessing from Search Console alone.

Put these checks on autopilot.
