SEO audit checklist to know what to check first

Start by knowing if the important pages exist, are accessible and respond to an intention. Then review quality, performance, authority and conversion.

An SEO audit should prioritize by impact, severity, effort and dependency. First check access and indexing; then architecture, content, experience, structured data, authority and measurement. A report with hundreds of warnings in no order is not an action plan.

[01] Base

1. Access, crawling and indexing

  • HTTP states, redirects, robots and noindex.
  • Sitemap with canonical and indexable URLs.
  • Canonicals, parameters, duplicates and orphan pages.
  • Differences between initial HTML and rendered content.

[02] Map

2. Architecture and intention

  • One function and one parent intent per URL.
  • Navigation hierarchy, breadcrumbs and depth.
  • Cannibalization between services, articles and local pages.
  • Internal links with anchors and useful destinations.

[03] Quality

3. Content, on-page and trust

  • Title, description, H1 and hierarchy consistent.
  • Complete response, authorship, date, and evidence where applicable.
  • Duplicate, outdated or unintentional content.
  • Complete structured data also visible on the page.

[04] Experience

4. Performance, accessibility and conversion

  • Core Web Vitals and resources per template.
  • Images, fonts, scripts and third parties.
  • Navigation, focus, forms and error states.
  • CTA, events and journey to lead or sale.

[05] Plan

5. Convert findings into backlog

Each finding needs evidence, affected URLs, impact, severity, effort, responsible party, dependency and form of validation. Group quick wins, blocks, structural improvements and experiments so as not to execute them in order of appearance.

[FAQ] Questions

Preguntas

How often should an SEO audit be done?
After migrations or large changes and when falls, blockages or disordered growth appear. Continuous monitoring avoids repeating a complete audit per routine.
Is an automatic tool enough?
It serves to inventory signals, but it does not know intention, business, execution capacity or impact on its own. Prioritization needs human analysis.
