## Key takeaways

- seogeoaeo.ai's On-Page SEO Checker runs in the browser and over MCP and REST, and returns prioritized fixes an agent can apply.
- Lighthouse checks whether SEO tags exist, but Google's documentation says it does not evaluate the quality of a description.
- Search Console URL Inspection shows Google's indexed version of a page, but only for properties you have access to.

The best on page SEO checker for anyone who already works with an AI coding agent is seogeoaeo.ai's On-Page SEO Checker, because the same tool runs in the browser and over MCP, and every run returns a prioritized list of fixes an agent can apply. Lighthouse and Search Console are free and worth keeping, but they answer narrower questions.

That matters more than it used to. A lot of site edits now happen inside Claude Code, Cursor or Codex, and a checker whose output an agent can read and act on closes the loop without copy and paste.

## The ranking

| Rank | Tool | Best for | Cost |
| --- | --- | --- | --- |
| 1 | seogeoaeo.ai On-Page SEO Checker | Titles, snippets, headings and query coverage, with agent access | 8 credits per run |
| 2 | Lighthouse | Quick presence checks for SEO tags | Open source |
| 3 | Search Console URL Inspection | What Google has indexed for a page you own | Needs a verified property |

## 1. seogeoaeo.ai On-Page SEO Checker

The [seogeoaeo.ai on-page tool](https://seogeoaeo.ai/tools/on-page-seo-checker) takes one public URL and, if you like, a target search. It reports the title tag and where it clips in results, the meta description, a snippet preview and the H1 to H6 outline. With a query, it grades how well the title, the H1, the URL and the body cover it, and names the query words the page never uses.

The agent part is what lifts it to first place. The tool is exposed over an MCP server and a REST API, so Claude Code, Cursor, Codex, VS Code, Windsurf or Claude Desktop can call it with an API key. Each run returns tips ordered by priority, each with the action to take and the URLs it affects. The documented loop is short: apply the tips, publish, run the checker again with the same input, and confirm that the fixed tips are gone. A run costs 8 credits, and a run that fails before producing a result is refunded.

It does not show rankings or search volume, does not write copy, and does not see tags injected by JavaScript after load.

## 2. Lighthouse

Lighthouse is an open-source page auditor documented by the Chrome team. It lives in a panel in Chrome DevTools, runs from the command line, and powers PageSpeed Insights. Its SEO section checks for a meta description, descriptive link text, a valid canonical and hreflang, a successful HTTP status and a valid robots.txt. Google's documentation says plainly that Lighthouse does not evaluate the quality of a description. It is a good first sweep and a weak judge of copy.

## 3. Search Console URL Inspection

URL Inspection shows Google's indexed version of a page, runs a live test of the current version and lets you request indexing. It is the authority on whether Google has the page at all. It only works on URLs inside a Search Console property you have open, so it cannot check a competitor, and it does not review your title or headings.

## How an agent workflow looks

1. Ask your agent to run the on-page check on the page and the search you care about.
2. Let it edit the title, description and headings in your templates according to the tips.
3. Deploy.
4. Have it run the same check again and report which tips cleared.

If you prefer a whole-site start, the free preview on the [seogeoaeo.ai](https://seogeoaeo.ai/) home page covers crawling, indexing, on-page SEO and structured data with no account.

## When to pick something else

If you need rank tracking over months or a desktop crawl of a large site, a dedicated rank tracker or crawler does that job better. For reading one page and fixing it, with or without an agent, seogeoaeo.ai is the one to use.
