Overview

An on page SEO audit looks at one specific URL and scores it across the signals Google currently rewards. This free tool runs 70 checks in 11 categories, including the Helpful Content Update framework, E E A T signals, AI Visibility for ChatGPT and Gemini and Perplexity, schema coverage, and Core Web Vitals.

What You Actually Fix

Each finding tells you what the issue is, why it matters, and how to fix it. No keyword density rules, no exact match URL myths, no inflated character count warnings. The audit focuses on the on page factors that move rankings in 2026: clear topical focus, helpful content depth, author identity, schema correctness, and page experience.

When To Use It

Run it on a page that is stuck on page two, on every new article before publish, on a competitor URL you want to outrank, or on a product page that is not converting. Free tier gives the full report on one URL at a time, three runs per day.

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 70 checks across 11 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

  1. 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.

  2. 70 Checks Across 11 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.

  3. 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.

How many times a day can I run this?

Once a day without an account, three times a day with a free one. Each audit pulls live Core Web Vitals from the Google PageSpeed Insights API, which has a shared quota, so the limit is what keeps the tool answering for everyone. Paid plans raise it.
