Our free SEO content optimization tool scores your draft against the top-ranking pages already winning your target keyword (simply add the top 10 search result URLs from Google to compare).
Paste your content or URL, add up to 10 competing search results, and get a side-by-side breakdown of keywords and a ready-to-use GPT prompt to close the gap in a matter of seconds, without any sign-up needed.
The Originality.ai Content Optimizer is a free content optimization tool that helps writers, content teams, and digital marketing professionals optimize content for search engines.
Once you add the competing search result URLs (up to 10), it benchmarks your draft or blog post directly against those competitor pages for your primary keyword, meaning your content brief is built from the pages you are actually competing with.
Built for content teams that prefer fast, actionable recommendations during the writing process.
There is no sign-up needed to start using the optimizer itself, so you can plug it straight into your content creation workflow.
The optimizer is user-friendly and drops into your existing content workflow. Here is how to start optimizing in five simple steps.
Decide on the main keyword you want the page to rank for and enter it into the input area. This is the term the optimizer uses as your reference point. Pick a specific keyword with real search volume and a manageable keyword difficulty score from your keyword research tool of choice.
Add the URL of your existing content, or paste your draft directly into the text area. The optimizer treats both in the same way, reading the full word count and comparing it against the competition. This works for blog posts, landing pages, comparison pieces, or any other content type where SEO matters.

Run a Google search for your primary keyword and grab the top 10 URLs that match the type of content you are producing. Stick to direct competitors, like pages with the same search intent, not loosely related listicles or YouTube results. The closer the match, the better.
Hit submit. It’s that simple! Then, a color-coded results table will load. Each keyword shows its density in your draft to bring you within 0.25% of the sample. Close the gap and match the pages already earning organic traffic for your target keyword phrase.
Three buttons at the bottom of the page help you act on the results without leaving the writing process.
A: Export to CSV. This option exports the full keyword table as a CSV and gives content teams the underlying data to reuse for keyword research, content briefs, or further competitive analysis.

B: Export GPT prompt. This option copies a ready-made ChatGPT prompt to your clipboard. The prompt can then be used to ask your AI tool to expand your article by three paragraphs and naturally weave in the keywords you are missing.


C: Show keyword highlighting. This option opens a text panel that highlights the top keywords in one color and your primary keyword in another. You can then edit the highlighted text directly, so you can paste it back into the input area and re-scan it to check as you optimize.

A content optimizer earns its place in the content lifecycle for one crucial reason: it closes the gap between what you have written and what is actually ranking.
Many writers can produce high-quality content, but it’s more challenging to produce content that outperforms the top-ranking pages on a specific keyword phrase.
Optimization tools fix that by giving you data-driven insights rather than relying on instinct.
Here are some top benefits of content optimization:
It’s no secret that the market for content optimization software is crowded. Many SEO tools all promise a content score, a grading system, and actionable recommendations.
The right fit depends on your business goals and your content production volume.
A few questions worth asking when selecting a content optimization tool:
If you’re looking to optimize your content and get ahead of up to 10 competing URLs, our free content optimizer is a top choice.
Content optimization works best when it’s incorporated into your process. A repeatable content workflow looks something like this:
Keyword density is the percentage of times a specific keyword appears in your content relative to the total word count and remains a useful proxy for topical coverage. If the top-ranking pages all use a phrase three or four times and yours doesn’t use it at all, you have a gap.
To run a keyword density check with the Originality.ai Content Optimizer:
The Originality.ai Content Optimizer is one of the most helpful ways to turn a finished draft into a piece that actually ranks.

A content optimizer is a piece of software that analyzes your draft against the top-ranking pages for a target keyword and tells you what is missing. It scores keyword density, surfaces related keywords, and key phrases. This provides writers with actionable ways to improve on-page SEO before the piece goes live.
You enter a primary keyword, paste your content or its URL, and add up to 10 URLs you want to benchmark against. The tool then calculates keyword density, compares your draft to the top-ranking pages, and returns a color-coded table showing where to add or trim.
Yes. The Content Optimizer itself is free to use, with no signup. Originality.ai does offer paid plans for premium tools, but the optimizer is a standalone free tool.
There is no universal right answer, as it depends on the keyword and the pages already ranking. As a rule of thumb, aim for parity with the top-ranking pages. For example, if their average density for your primary keyword is 1%, then target a similar range.
