## Key features

- **SEO crawler:** Crawls sites of several million pages for indexability, status codes, titles and meta tags, depth, response time, sitemaps, orphan pages and internal PageRank.
- **Real-time log analysis:** Shows live which pages Googlebot crawls most, mobile against desktop bots, server response times, cached pages, bad bots and visits from Google Discover and News.
- **Cross analysis:** Merges crawl and log data to find orphan, ignored and inactive pages, redirects and errors Googlebot does not follow, and sitemap crawl rates.
- **Page categorization:** Group URLs into multi-level categories that apply live and to past data, to see which page types bots favor.
- **API:** Raw and aggregated crawl, log, Search Console and CrUX data in JSON, with no limit on calls or rows, and BigQuery and Power BI compatible.

## Good for

- SEO teams on large French or European sites that want Googlebot activity in real time
- Watching a site migration or HTTPS switch as bots react to it
- Data teams pulling SEO data into their own dashboards

## Worth knowing

- No prices are published: the old pricing page no longer exists and the site offers only a demo booking.
- Its terms of sale cover business customers only and say prices are set in euros, excluding tax.
- Subscriptions renew automatically and must be cancelled by registered letter at least one month before the renewal date.
- Log analysis needs your server log files to be connected to the service.

## ToolGPA grades

**GPA: 2.0 out of 4**, graded Oct 23, 2026. Seolyzer joins a crawler with real-time server log analysis and Search Console data, so you see which pages Googlebot crawls, ignores or never finds, and its API has no call limits. There's no published price, only a demo booking. It's sold to businesses only, and cancelling takes a registered letter a month before renewal.

- **Value for money: C.** No price is published. The old pricing page is gone and the site offers only a demo booking, so the cost comes out on a sales call, in euros, before tax.
- **Free plan and trial: F.** Nothing free on record: no free plan and no trial, just a demo.
- **Features: B.** Crawls sites of several million pages, shows Googlebot's crawl in real time from your logs, merges the two to find orphan and ignored pages, and serves raw crawl, log, Search Console and CrUX data through an API. The listing shows no gap in the core job.
- **Ease of use: C.** No rating on record. The log reports stay empty until your server logs are connected, and then there are page categories to build.
- **Platforms and integrations: B.** Web only. It connects to Search Console and works with BigQuery and Power BI through an API with no limit on calls or rows.

## Keep it, or make your own?

**Keep it.** The plain part of Seolyzer you could make: internal linking. What surrounds it you could not. The 5 things listed below take a company, not a weekend. That makes this kind of software worth paying for, not this one in particular: 64 of the 83 other technical SEO tools grade higher.

- You could make: Internal linking: an app builder makes this well.
- You could not: A crawler that checks every page of a site.
- You could not: Millions of server log lines read to see what search bots crawl.
- You could not: It plugs into other products, Google Search Console, BigQuery and Power BI among them, and has an API.
- You could not: Sharing with other people, which means accounts and invitations.
- You could not: The depth: we grade its features B, which means it covers the whole job.

A judgement by ToolGPA from this listing, by rules that are the same for every tool. Nothing was built to test it.
