About the tool
What is the On-Page SEO Audit Pro?
The On-Page SEO Audit Pro is a free single-URL deep audit that scores any page against 122 Google-aligned checks across 18 categories. Unlike site-wide audits that grade a whole domain at once, an on-page audit drills into one URL at a time to tell you exactly why a specific page is not ranking and what to change.
The audit is built for the 2026 ranking environment: Helpful Content Update signals, E-E-A-T evaluation, AI Visibility scoring for ChatGPT and Claude and Gemini and Perplexity, schema coverage validation, and Core Web Vitals. It deliberately ignores debunked checks like exact-match URL rules, keyword density targets, and inflated character-count warnings.
Every finding includes the rule being tested, why it matters, and how to fix it. The audit works without a target keyword, but providing one unlocks intent-match scoring and content-gap analysis against the SERP for that query.
Step by step
How to use this tool in 3 steps
-
Step 01
Paste the URL you want to audit
Drop any public URL into the form. A target keyword is optional, but adding one unlocks intent scoring and helps the AI Visibility section grade whether the page answers the search intent fully.
-
Step 02
122 checks across 18 categories
The audit runs HCU signals, E E A T, AI Visibility, schema coverage, Core Web Vitals, indexability, internal links, image SEO, headings, structure, and Page Experience checks against the page in seconds.
-
Step 03
Read the prioritised fix list
Get an overall score, a category breakdown, and every failed check with a one-line fix. Re-run the audit after changes ship to confirm the page now passes the rule you fixed.

FAQ
Frequently asked questions
What is an on-page SEO audit?
An on-page SEO audit reviews one specific URL against the signals Google currently rewards. It looks at content quality, helpfulness, E E A T, schema coverage, Core Web Vitals, indexability, and on-page structure, then returns a score, a breakdown by category, and a list of failed checks with fixes.
How is an on-page audit different from a site audit?
A site audit crawls many pages and grades the whole domain. An on-page audit drills into a single URL and runs deeper checks specific to that page. Use our Site Audit Pro to find which pages need work, then run this on-page audit on each problem URL to learn exactly what to change. For schema-specific validation use the Schema Intelligence Analyzer.
Do I need to enter a target keyword?
No. The audit runs full content, technical, and schema checks without a keyword. Providing one unlocks intent-match scoring, content-gap analysis against the SERP, and an AI Visibility prediction for that specific query, so it is worth adding if you have one.
What does the Helpful Content Update check actually measure?
It grades the page against Google's HCU rater guidelines: is the content original, does it show first-hand experience, does it include expert voice, does it cover the topic with the depth a real reader needs, and is the author visible and credible. These are the signals that drove the HCU rollouts.
How accurate is the AI Visibility score?
The AI Visibility score predicts the relative likelihood of citation across ChatGPT, Claude, Gemini, and Perplexity based on schema coverage, source quality, author identity, and on-page structure. It is a directional signal, not a guarantee, since the underlying models change their citation behaviour frequently.
How often should I re-run the audit after a fix?
Re-run it immediately after each change to confirm the failed check now passes. The audit re-pulls live Core Web Vitals and re-parses the live HTML, so cached metrics will not mislead you. Wait two to three weeks before judging the ranking impact in Search Console.
Why does the free tier limit me to three runs per day?
Each audit pulls live Core Web Vitals from the Google PageSpeed Insights API, which has shared quota. The three-runs-per-day free tier covers any normal author or solo SEO workflow. SBMM Pro lifts the cap and adds bulk URL audits.
