Free SEO Checker — What Does It Analyze?
Our free SEO checker analyzes any publicly accessible URL across 20+ SEO factors — from technical foundations to AI readiness and alt-text quality. Unlike simple pass/fail tools, we provide concrete action items that tell you exactly what to fix and why.
The 5 Audit Categories
Technical SEO (25%)

Our Differentiator: Alt-Text Quality Analysis
Most SEO tools only check whether an alt attribute exists. We analyze the quality of the alt text:
Critical
alt="" or missing
Warning
"image", "photo", "img1" or < 3 words
Good
"Team discussing AI strategy in office"
GEO: Why AI Readiness Matters Now
Generative Engine Optimization (GEO) is the new discipline alongside classic SEO. ChatGPT, Google SGE, Perplexity and Bing Copilot rely on structured data to cite websites. Our checks show how well your page is positioned for these AI systems:
FAQ Schema
FAQPage JSON-LD is preferentially cited by ChatGPT and Google SGE.
Speakable Property
Marks the most important text sections for AI assistants and Voice Search.
Question-based Content
Pages that directly answer user questions are cited more often by AI systems as a source.
How the Score Is Calculated
The overall score is a weighted average of all 5 categories. Content has the greatest influence at 40%, since high-quality content remains the strongest ranking factor. Technical factors (25%) form the foundation. Schema Markup and GEO readiness (20% combined) are becoming increasingly important.
Why Regular SEO Analysis Is Essential
Google updates its algorithm hundreds of times a year. What worked 12 months ago may be hurting your rankings today. Regular SEO audits catch problems early — a missing canonical tag can split your ranking strength across duplicate URLs, while a single broken internal link can interrupt your site's link equity flow. Our free SEO tool gives you a snapshot in seconds, without the overhead of enterprise software.
For Austrian SMBs, local SEO signals matter especially: correct hreflang tags for German-language pages, structured data for local businesses (LocalBusiness schema), and consistent NAP data (Name, Address, Phone) across your site. We check the technical prerequisites for all of these.

Frequently Asked Questions
Is this SEO checker really free?
Yes, completely free. You get 3 analyses without registration. Subscribe to our newsletter to receive 5 additional credits. No credit card, no trial — genuinely free.
How does this SEO checker differ from tools like Seobility or Screaming Frog?
We focus on actionable insights rather than overwhelming reports. Our alt-text quality analysis is unique — we evaluate whether the alt text is descriptive, not just present. We also check GEO/AI readiness (FAQ Schema, Speakable) which most traditional tools ignore.
How often should I check my website's SEO?
We recommend at minimum a monthly check of your most important pages (homepage, service pages, top-traffic articles). After any major content changes, check immediately. After a Google algorithm update, run an audit within 72 hours.
What does an SEO score of 75+ mean?
A score of 75–100 means your page covers the most important technical and content SEO factors well. It does not guarantee position #1 — off-page factors (backlinks, domain authority) also play a role — but it means your on-page foundation is solid.
Can I check competitor websites?
Yes. Enter any publicly accessible URL. Checking competitor pages is a common and legitimate SEO practice — you can see what structured data they use, how their content is structured, and where you can differentiate.
