Behind the analysis
How we generate your results
Four steps, run against your site's live environment. Nothing is cached and nothing is guessed.
The technical crawl
We request your page with a real browser user-agent, following redirects and retrying the www variant if the apex domain refuses us. Then we probe robots.txt and sitemap.xml — if search engines cannot reach you, nothing else matters.
Code and on-page analysis
We parse the returned HTML for title, meta description, canonical, heading hierarchy, image alt coverage, structured data, and link structure — checking whether your markup tells search engines a clear story.
Performance stress-test
We run your URL through Google PageSpeed Insights on both mobile and desktop, pulling live Core Web Vitals rather than estimates, and flag the metrics outside Google's own thresholds.
Scoring and prioritisation
Every check is scored per category and rolled into one number. Failing checks are sorted into a fix-first list, so the report ends with an action plan instead of a wall of data.

Questions
Frequently asked questions
Is this audit really free?
Yes. There is no account, no trial, and no cap on how many pages you audit.
Which page does it audit?
The exact URL you enter. Audit your homepage first, then run the pages that matter most to you individually.
Why is my score lower than another tool's?
Every tool weights checks differently. Use the score to track your own progress over time rather than to compare against another tool's number.
Do you store my results?
No. The audit runs on request and nothing is saved. Export the PDF or email it to yourself to keep a copy.
Why did the audit fail on my site?
Some hosts block automated requests, and pages that build their content with JavaScript return very little HTML to analyse. Both show up as a fetch error or an unusually low word count.
Can you fix these issues for us?
Yes — that is our day job. Send us the report from the contact page and we will scope the work.
