What We Check

Our audit tool checks your page against 14 SEO factors. Click any item to learn more and find out how to fix issues.

Page Title Tag
Title tags are the most important on-page SEO element. Check length, uniqueness, and keyword use.
Meta Description
Compelling descriptions improve click-through rates from Google search results.
HTTPS Security
A confirmed Google ranking signal. Ensures data between your site and visitors is encrypted.
Heading Structure
Correct use of H1–H6 tags signals content hierarchy and topic relevance to search engines.

Frequently Asked Questions

What does SEO Checkup analyse?
SEO Checkup analyses over 30 factors across three disciplines. Traditional SEO checks cover title tags, meta descriptions, heading structure, image alt text, canonical URLs, HTTPS security, page size, Open Graph tags, Twitter Cards, structured data, robots.txt, and XML sitemaps. AEO checks look for FAQ schema, question-format headings, and featured snippet readiness. GEO checks cover llms.txt, AI crawler access, author attribution, E-E-A-T signals, content freshness, and authority citations.
Is SEO Checkup free to use?
Yes — completely free with no account, no sign-up, and no usage limits. Enter any publicly accessible URL and receive a full audit report in seconds. Reports are saved and can be shared via a permanent link.
What is AEO and why should I care?
AEO stands for Answer Engine Optimisation. It focuses on structuring your content so Google and AI tools can extract it as a direct answer — appearing in featured snippets, Google AI Overviews, and People Also Ask boxes. As noted by Google's developer documentation, FAQ schema is one of the clearest signals you can provide. Our AEO checks identify whether your page qualifies and what's missing.
What is GEO and how is it different from SEO?
GEO stands for Generative Engine Optimisation — making your content visible and citable by AI tools such as ChatGPT, Claude, Perplexity, and Bing Copilot. Traditional SEO optimises for ranked link results in Google. GEO optimises for inclusion in AI-generated responses. Learn more about GEO →
Why might my score be lower than expected?
Scores under 80 are typically caused by missing AEO and GEO signals — newer disciplines that most sites haven't addressed yet. Common issues include missing FAQ schema, no llms.txt file, AI crawlers blocked in robots.txt, no author attribution, and missing dateModified in schema. Each failing check links to a plain-English guide explaining exactly how to fix it.
Can I share my SEO report with someone else?
Yes. Every report is saved and given a permanent URL (e.g. your-domain.com/report/123). A share link and copy button appear at the top of every report. Enable Private mode before running the audit if you prefer your results not to be saved or listed in Recent Checks.
