AIOSEO audit: the Site Audit, the SEO Checklist and the free SEO Analyzer in All in One SEO, and how to run them in order

What each of All in One SEO's three audit tools checks, read from aioseo.com and WordPress.org on 22 October 2026, and the two checks worth adding from outside the plugin.

Published by AI Knows Us · Updated 21 October 2026

An AIOSEO audit is the SEO audit built into All in One SEO (AIOSEO), a WordPress plugin. It comes in three parts: a Site Audit that reviews every post and term and ranks the fixes, an SEO Checklist inside the plugin that walks you through setup tasks by priority, and a free SEO Analyzer on aioseo.com that scans any URL without installing anything. Run the free analyzer for a quick read, then use the Checklist and Site Audit inside WordPress to fix what it finds. Everything here was read from aioseo.com and the plugin's WordPress.org listing on 22 October 2026. (If you searched "AIO SEO" meaning Google's AI Overviews, that is a different subject, covered in our guide to generative search optimization.)

What AIOSEO is, briefly

All in One SEO describes itself as the original WordPress SEO plugin, founded in 2007. Its WordPress.org listing on 22 October 2026 showed version 5.0.3, last updated on 7 October 2026, more than 2 million active installations and an average rating of 4.7 out of 5 from about 5,200 ratings. There is a free version on WordPress.org, which the listing calls the lite version of AIOSEO Pro, and paid Pro plans sold on aioseo.com.

The plugin covers titles and meta descriptions, schema, XML sitemaps, local SEO, redirects and internal linking. It has also moved into AI: an AI content generator for titles and descriptions, an llms.txt generator, an MCP server so AI agents can read and update a site's SEO, and an "AI Insights" keyword report that tracks how a brand appears in AI search. AIOSEO is therefore a WordPress SEO plugin and, since its AI tracking launched, a product in the AI visibility category too.

The three audit tools, and what each one does

ToolWhere it livesWhat it checksBest use
SEO Analyzeraioseo.com/seo-analyzer, no installMetadata, content, keywords, internal links, schema and technical issues for a URLA first look at any site, including a prospect's
SEO ChecklistAll in One SEO, General Settings, SEO Checklist tabSetup tasks and important issues, with a priority and a time estimate for eachGetting a new install configured properly
Site AuditInside the pluginEvery post and term on the site, with prioritised fixes and a health scoreOngoing monitoring of a live site

Alongside these, TruSEO scores each post's on-page SEO and readability against focus keywords as you write, and a Headline Analyzer scores post titles. Those are page level tools; the three above look at the site.

How to run an AIOSEO audit, step by step

1. Start with the free SEO Analyzer

Enter your homepage URL on aioseo.com/seo-analyzer. AIOSEO says the analyzer checks metadata, content quality, keywords, internal links, schema and technical SEO and returns a report with suggested fixes. Save the report. It is your baseline before you change anything.

2. Work through the SEO Checklist in the plugin

In WordPress, open All in One SEO, then General Settings, then the SEO Checklist tab. AIOSEO's documentation, last updated on 6 October 2026, describes what you will see: a progress bar showing tasks completed, tabs for incomplete and completed tasks, and a table with each task's title, priority and time estimate. Filter by priority (High, Medium, Low, Optional) and clear the High tasks first. Each task has a "View Explanation" link that says what to do, and a "Dismiss" link for tasks that do not apply to your site.

3. Read the Site Audit by severity

AIOSEO describes its Site Audit as a full audit of every post and term with prioritised fixes, a Critical Issues tab, a health score and site speed feedback tied to Core Web Vitals. Work in this order:

  • Critical issues: anything that stops a page being crawled or indexed, such as a noindex on a page that should rank.
  • Template issues: missing or duplicate titles and descriptions that repeat across a post type. Fix the template setting once in AIOSEO, rather than each post.
  • Content issues: thin posts and missing focus keywords, which TruSEO helps you fix one page at a time.
  • Speed: act on the site speed findings with your host or theme developer.

4. Confirm against Google's data

A plugin audit sees your site from the inside. Google Search Console shows which pages Google actually indexed and why others were left out. AIOSEO connects to Search Console through its Search Statistics module, but check the Page indexing report in Search Console directly as well.

5. Re-run after changes

Re-run the SEO Analyzer after a round of fixes and compare it with your baseline. Keep the Site Audit running so new posts are checked as they are published.

What an AIOSEO audit covers well, and what to add

A plugin audit has one big strength: it can fix what it finds, because it controls the titles, descriptions, schema and sitemaps it is checking. That makes it very practical for a WordPress site owner without a developer.

Two things are worth adding from outside the plugin. First, a crawler that sees the site the way a search engine does, following links from the homepage, finds orphan pages, redirect chains and broken links in theme files that a database view can miss. Second, Search Console data, as above. If your site also serves a local area, our guide to local SEO on WordPress covers what the site itself must do, whichever plugin you use.

On plans: AIOSEO sells a free lite version and paid Pro plans, and features differ by plan. Check aioseo.com for which plan includes the full Site Audit before you rely on it, since plans change.

Questions about the AIOSEO audit

Is the AIOSEO SEO audit free?

The SEO Analyzer on aioseo.com is free and needs no install. The plugin has a free lite version and paid Pro plans, so confirm on aioseo.com which plan includes the full Site Audit.

Where do I find the SEO Checklist in AIOSEO?

In WordPress, go to All in One SEO, then General Settings, and open the SEO Checklist tab.

Does AIOSEO check site speed?

AIOSEO says its Site Audit reports what is slowing a site down and gives steps to improve Core Web Vitals. Confirm the fixes with Google's PageSpeed Insights.

Can I audit a site that does not use AIOSEO?

Yes, with the free SEO Analyzer on aioseo.com, which scans any URL. The Checklist and Site Audit need the plugin installed on a WordPress site.

Is AIOSEO the same as AIO in AI Overviews?

No. AIOSEO is the All in One SEO plugin. AIO is also a common short form for Google's AI Overviews, which is a separate topic.

Checking the answer, not only the site

AIOSEO's newer AI Insights report shows that WordPress site owners now want to know how their brand appears in AI search, and that is a sensible question to keep asking after the audit is clean. A site can pass every check and still be left out when a buyer asks ChatGPT, Gemini, Claude or Perplexity for a recommendation, because those answers lean on sources beyond your own pages. AI Knows Us measures what each assistant says about a business and which sources shape the answer.
