Common Mistakes

Running an audit without prioritizationA list of 50 issues without priorities is useless. Start with critical ones: duplicate titles, broken canonical, no HTTPS.

Fix and forgetSEO issues reappear with content updates and deploys. Auditing must be a regular process, not a one-time event.

Focusing only on title and descriptionMeta tags are only 10% of an SEO audit. Core Web Vitals, link structure and indexation are often more important.

Ignoring the mobile versionGoogle uses Mobile-First Indexing. Mobile version issues directly affect search rankings.

Best Practices

Start with critical blockersNoindex on production, broken canonical, no sitemap — these stop indexation. Fix them first.

Run audits monthlyNew content, redirects, plugin updates — all change the site's SEO profile. Regular audits catch regressions.

Track Core Web Vitals over timeA single measurement means nothing. Track LCP, CLS and INP trends after every deploy.

Validate fixes through GSCGoogle Search Console confirms that Googlebot saw your fixes. Use the URL Inspection Tool.
