Free AI SEO content checker

Be clear about the scope before you rely on it. This is an AI review of text you paste. The review itself starts by saying so. It has no access to your live page, your site or any search data.

It reviews:

• Title tag length, against the usual guidance of about 50 to 60 characters.
• Meta description length, against about 120 to 160 characters.
• Keyword use, if you gave a keyword: whether it appears in the title, the opening, the headings, and roughly how often in the body.
• Heading structure in the text you pasted.
• Readability of the copy.
• A prioritized list of fixes.

It cannot see: page speed, mobile rendering, internal or external links as they exist on the live page, backlinks, indexing status, canonical tags, structured data, images and alt text, rankings, or search volume. For those you need a crawler or Google's own tools. The honest comparison is a second pair of eyes on the writing, not a site audit.

People searching for a "Copilot SEO checker" or "Copilot SEO analysis tool" often mean one of two things: asking Microsoft Copilot to review SEO, or an AI assistant that does it for them. Copilotly is an independent product and is not affiliated with Microsoft Copilot.

What Copilotly can do is what this page does: review the on-page text you give it. In the chat, you can go further. Web search with cited sources can look up what currently ranks for a query so you can compare your angle against it, and deep research builds a sourced report on a topic before you write. Those are research aids. They do not replace rank tracking or a crawl.

Search engines show a title and description in results and cut them off by pixel width, not character count, so there is no exact limit. The ranges the tool uses are common guidance: roughly 50 to 60 characters for a title and 120 to 160 for a meta description.

• Titles. Put the words searchers use first. If the keyword is at the end, a truncated title may lose it. Make each page's title different from every other page on your site.
• Meta descriptions. They do not directly set your ranking, but they are your pitch in the results. Say what the reader gets, and use the keyword naturally. Google may rewrite them anyway.

The tool reports real character counts when you provide these, so you are not counting by eye. See Google's own guidance on title links and snippets for how they are actually chosen.

One keyword, used where it belongs: in the title, in the first paragraph, in at least one heading, and naturally in the body. There is no magic density number, and repeating a phrase to hit one makes the writing worse for people. If the review flags a high density, rewrite those sentences, and the paraphrasing tool can help vary the wording.

Match what the searcher wants. If the query is a how-to, the page should show how; if it is a comparison, compare. The tool judges your text against your keyword, but it cannot see which result types currently satisfy that query. Check the search results yourself or ask Copilotly chat with web search.

1. Draft the page. Use the text summarizer to check that your opening paragraph really carries the page's main point.
2. Paste it here with the keyword, title and meta description.
3. Fix the top items. Rewrite weak sections in the Copilotly extension, which works in your CMS's text boxes, and compare changes word by word.
4. Re-run the check on the revised text, publish, then use Google Search Console for what the real page is doing.

Does the title tag matter?

Yes, as one of the main inputs for how your page is shown in results. Google's documentation on title links explains that it often uses the page's title element, but may build a different title if yours is empty, very long or does not describe the page.

Does the meta description affect ranking?

It is not a ranking lever, but it is your summary in the results. Google says it may use the meta description as the snippet when it describes the page better than the page text does.

Is there an ideal keyword density?

No. Google's guidance on helpful, people-first content asks you to write for readers, not for a count. Use the keyword where it fits and describe the topic fully.

Can a text-only review replace an SEO audit?

No. The next section lists what a crawler and Google's own tools cover.

Use Search Console after you publish

It shows the queries, impressions and clicks that real searchers produced, which no pre-publication review can. Use this checker before you publish and Search Console after.

Use the checker to polish, not to chase

Fix what makes the page clearer for a reader: a title that says what it is, a description that earns the click, headings that match the questions people ask. Then compare the result with what the text summarizer says your page is about.

Start at the top of the fix list

The review ends with a ranked list. The first items are the ones most likely to matter, such as a missing keyword in the title or an empty description. Do those before polishing smaller things.

Ignore advice that makes the text worse

If a suggestion makes a sentence awkward or inflates the keyword count, skip it. The goal is a clear page for the reader, which is also what Google's people-first content guidance asks for.

Remember what it cannot see

If your page is slow, buried in the site, or never indexed, perfect wording will not rescue it. That is for a crawler and Google's own tools to answer, not this review.

Rerun after edits

Paste the revised text and compare. You want the same page, clearer. When a section needs work, rewrite it in place with the extension and then check it again here.
