What to Focus On First

Not all issues are created equal—and we don’t treat them like they are.

While the list below covers common technical SEO priorities, our audits go further: We highlight the most urgent issues specific to your site, so you know exactly what to fix first.

Indexation gaps — Compare site:yourdomain.com with your sitemap.xml to spot missing pages
Robots.txt blocks — Make sure important URLs aren’t being excluded
Redirect chains & broken links — These waste crawl budget and hurt UX
Page speed & mobile usability — Core Web Vitals are now ranking signals
Meta titles & descriptions — Fix missing, duplicate, or poorly optimized tags
Canonical & duplicate content issues — Prevent dilution of ranking signals
