The alternative
The Seobility alternative for the AI search era
Seobility built the best free SEO checker of the last decade. We built the one for the next one, the AI search era it was never designed for.
Seobility: A 13-year-old German freemium SEO tool, acquired by saas.group in 2022, best known for its no-signup, URL-shareable SEO Check.
Summary
Seobility earned its position the honest way: a frictionless, no-signup, shareable SEO Check that ranks first for "seo checker" and a wiki built over a decade. We respect that. But its audit grades you for the 2015 ten-blue-links Google, its AI features are a shallow AI Overview indicator, and it ships zero structured data on its own pages. We are an AI-first audit that scores the signals classic Google and AI crawlers read, with a methodology page and a primary source behind every finding, plus answer tracking on six AI answer engines.

Where Seobility wins
Marketing is editorial here. We will not pretend a strong competitor has no strengths.
Thirteen years of compounded authority
Seobility registered its domain in 2012 and has been accumulating links and brand recognition in the SEO niche ever since. That is a multiplier you cannot buy, and on classic Google rankings for established head terms, it shows. A new entrant earns this over time; Seobility already has it.
A decade of wiki diagrams and content
Their 287-entry wiki and 150-plus custom, Creative-Commons-licensed diagrams represent years of design and writing investment. The diagrams in particular earn links through attribution when other sites embed them. We are building our editorial layer from scratch, deeper and more current, but they have a head start in raw volume.
A proven, frictionless freemium funnel
The no-signup, no-email, immediate-results, URL-shareable format is the cleanest acquisition funnel in the category, and Seobility perfected it. We match the format deliberately, because it works, rather than inventing a new one.
Where we win
AI visibility is native, not a bolt-on
Seobility ships an AI Overview indicator and basic crawlability flags. We score AI crawler readability, run a render-parity diff against a real JavaScript render, and track citation across ChatGPT, Claude, Perplexity, Gemini, and AI Overviews as a first-class pillar. The most common failure we find, a client-rendered site that is invisible to AI crawlers, is exactly what their audit cannot see.
Every finding shows its evidence and its source
We attach a confidence flag to every finding and link every check to a methodology page that cites a primary source. Seobility scores you without telling you how the number was produced or why the rule exists. We refuse to surface a finding without a confidence value, because a score without one is a credibility risk.
We ship the schema they do not
Direct inspection found zero JSON-LD across Seobility's homepage, wiki, and tool pages, a striking gap for a company that sells optimization. We ship comprehensive structured data on our own surfaces and audit yours, including the entity-graph work that increasingly decides AI citation.
The audit thinks per industry
A doctor, a lawyer, a CPA, and an MCA broker need materially different SEO playbooks. Our vertical adapters reshape severity, recommended fixes, competitor sets, and citations per industry. Seobility, like the horizontal incumbents, gives everyone the same generic findings.
The bottom line
If you want a battle-tested free checker for classic Google and a wiki to browse, Seobility is a fine, inexpensive choice with a long track record. If your buyers research you through ChatGPT, Perplexity, and AI Overviews, and you need an audit that measures whether those engines can read and cite you, with the evidence behind every finding, that is the gap we were built to fill.

Is SEO for AI Agents a Seobility alternative?
Yes, specifically for the AI search era. We match Seobility's no-signup, URL-shareable, scored audit format and add what it lacks: native AI visibility scoring across ChatGPT, Claude, Perplexity, Gemini, and AI Overviews, render-parity diffing, per-finding confidence and citations, and industry-tailored findings.
Does Seobility track ChatGPT and Perplexity citations?
No. As of 2026 Seobility ships an AI Overview indicator and basic AI-crawler crawlability flags, but not citation tracking across ChatGPT, Claude, or Perplexity, no share-of-voice across LLMs, and no prompt mining. AI visibility is a first-class pillar for us.
Is Seobility cheaper?
Seobility's paid plans start around 49.90 euros per month. Our Starter plan is $49 a month and adds weekly AI-visibility tracking, and our free tier returns a real, full audit. We compete on AI-era depth and evidence, not only on price, and our free tier is genuinely useful rather than a five-check demo.
