Frequently Asked Questions
What does the SEO score mean?
The score (0-100) measures how well your page follows SEO best practices across 7 categories: title/meta, headings/content, technical, security, social media tags, schema markup, and indexability.
Why is my DA/PA not shown?
Domain Authority (DA) and Page Authority (PA) are Moz proprietary metrics that require their paid index. We link you to free DA/PA checkers directly.
What is AEO and why does it matter?
AEO (Answer Engine Optimisation) is optimising for AI assistants and featured snippets. FAQ, HowTo, and Article schema are key signals.
How many free scans do I get?
5 scans per day on the free plan. Upgrade to Pro for unlimited scans and a full watermark-free PDF report.

Does the Website SEO Checker work offline?

How current is the data returned by the Website SEO Checker?
The Website SEO Checker fetches live data in real time each time you run it. Results reflect the current state of the server or domain at the moment of the request.
Why does the Website SEO Checker sometimes return different results than other tools?
Results depend on the real-time state of the target server and DNS propagation, which can vary by geographic region and caching TTL. If you see inconsistencies, wait a few minutes and re-test — DNS changes can take up to 48 hours to propagate fully worldwide.
Does the Website SEO Checker work on all browsers?
Yes. The Website SEO Checker is built with standard browser APIs and works on all modern browsers including Chrome, Firefox, Safari, and Edge — on both desktop and mobile. No plugins, extensions, or third-party software are required.
