Six checks that explain why the top 3 outrank your page
Most free SEO checkers grade a page against a fixed checklist. A page can pass every item on that list and still lose, because Google ranks pages against each other for one query. This checker reads the pages that rank for your keyword today and compares your page with them.
Top 3 comparison
Your page side by side with the three organic results that rank for your keyword: page type, word count, keyword use, headings and links.
Search intent match
Search intent is the goal behind a search. The checker shows which page type Google prefers for your keyword, such as a guide, a service page or a product list.
Missing subtopics
The questions and sections the top pages answer that your page skips. Each one comes from the headings of pages that already rank.
Indexability and tags
Status code, noindex, canonical tag, title tag, meta description and H1. A canonical tag tells Google which URL is the main version of a page.
Content focus
The share of your text that sits in repeated, near-identical blocks. Long templated lists add words but rarely answer the searcher's question.
Real-user speed
Core Web Vitals from the Chrome UX Report, which records how fast and stable your page is for real Chrome users on mobile.
How the free checker scores your page
The score adds up nine checks to a total of 100 points. The weights favour intent and subtopic coverage, because a page that answers the wrong question rarely ranks, however clean its tags are. If a check has no data, such as speed for a page with little traffic, we leave it out and scale the score to 100.
What we measure
How many of the subtopics from the top-ranking pages your page covers.
HTTP status, robots.txt, noindex rules and the canonical tag.
Whether your page type matches the type Google ranks most for the keyword.
Keyword use, position and length compared with the top 3 titles.
One clear H1 that contains the keyword or a close variant.
Share of text in repeated blocks, the keyword in the first 100 words, and length compared with the top pages.
Core Web Vitals (loading, responsiveness and layout stability) from real Chrome users.
Present, a readable length, and relevant to the keyword.
Mobile viewport, image alt text, structured data and the page language tag.
From URL to a ranked fix list in three steps
Enter your page and keyword
Add the landing page URL, the keyword you want it to rank for and the country you target. The checker uses the Google results for that country.
We read the pages that rank
The checker fetches your page and the top organic results, then compares page type, headings, subtopics, tags, links and speed.
Fix the highest-impact gaps first
You get a score, a side-by-side table and a fix list ordered by impact. The top 3 fixes are open right away. Your email unlocks the rest, still for free.
Use the score as a to-do list, then write for people
On-page SEO covers the parts of a page you control: its content, headings, tags and code. A checklist tells you if those parts exist. A comparison tells you if they are good enough to compete for one keyword, in one country, this month.
Treat every fix as a question about your reader. A missing subtopic matters because people who search that keyword expect the answer. A shortcut, such as adding the keyword to every heading or padding the page with repeated text, tends to lower quality and can work against you. Google describes this in its guidance on helpful, people-first content.
A high score does not guarantee a ranking. Links, brand demand and the reputation of your whole site also count. For pages in regulated fields such as health or finance, Google applies higher standards of trust, so expert authorship and clear sources matter even more.
Questions about the free On-Page SEO Checker
Is the On-Page SEO Checker really free?
Yes. You see your score, the top 3 comparison and your first three fixes without signing up. Your email unlocks the full fix list. There is no trial, no credit card and no paid tier.
What does an on-page SEO checker do?
It reads the content and HTML of one page and reports what helps or blocks that page in search, such as the title tag, headings, indexing rules and speed. This checker also compares your page with the pages that rank for your keyword.
Why compare my page with the top 3 Google results?
Google ranks pages against each other for each search. The pages in the top 3 show what Google currently rewards for your keyword: the page type, the subtopics and the depth. Matching that standard is a more useful target than a generic checklist.
Which data does the checker use?
Search results and link counts come from Ahrefs. Speed comes from the Chrome UX Report, which records real Chrome users. Page content comes from the HTML each server sends, so text that loads only with JavaScript is not counted.
Why is my score different from other SEO tools?
Each tool weighs different checks. Most grade a page against fixed rules. This checker grades your page against the pages that rank for your keyword today, so the same page can score differently for two keywords.
How many pages can I check?
You can run up to 20 checks per day. The limit keeps the tool fast and free for everyone. Repeat checks of the same keyword use saved search data for seven days.
Does a high score guarantee a top ranking?
No. The score covers on-page factors only. Links, brand demand, site reputation and competition also affect rankings. Use the fix list to close clear gaps, and judge each change by whether it helps the person searching.
