SEO Humanizer: How a Normal Rewrite Lost 92% of an Article’s Links in Our Test

The writing type for a blog post is Blog post, and for a search-led article it is SEO article. The selector opens on Academic, which is built for essays and papers, so this one choice decides the route. Students working on coursework have their own guide to Academic mode.

1. Pick the writing type. Blog post, SEO article, Website or marketing copy, Email or business writing, or Everyday writing. All five run the SEO engine.
2. Add target keywords if you have them. Leave the field empty and the engine reads your headings.
3. Paste the draft and run it on the humanizer.
4. Read the line under the result. It says what was kept, counted on your actual output, for example “Kept for SEO: 6/6 headings, 4/4 links, 9/9 list items”, followed by your keywords.

The target keywords field tells the engine which terms to protect, and it appears for blog posts, SEO articles and marketing copy. Leave it blank and keywords are read from your headings. The primary keyword then stays in every paragraph that had it, and supporting keywords keep at least half their uses.

The surrounding language holds too: related phrases came through at 99 of 101 and named entities at 168 of 172. Those are the words that tell a reader what the piece is actually about.

A humanizer can add keyword stuffing, and in our test the whole-text route added the keyword 124 extra times across 20 articles. Our SEO engine added it zero times. A paragraph is refused if a keyword or related phrase shows up more often than you used it.

Stuffing is easy to miss on a read-through because every single sentence looks fine. It only shows when you count, so we count, and where the keyword count moved in the test it moved down.

Using AI to help write an article is not a problem for Google by itself; publishing pages in bulk with no added value is. Google’s spam policy describes scaled content abuse as many pages generated mainly to manipulate rankings rather than to help users, and it lists generating many pages with generative AI without adding value as an example. Its guidance on generative AI content says such tools can be useful for researching a topic and adding structure to original content (both read October 30, 2026). So spend the rewrite on articles worth publishing. The engine holds your figures exactly as they were, and confirming they were right stays with you.

You can humanize website and marketing copy through the same checks by choosing Website or marketing copy. A landing page keeps its section headings, its feature list, its prices and every link written into the text. Product names and figures stay put.

Business emails and everyday writing run on the same engine without the keyword field, so an email keeps its link, its dates and the names in it. Running your own article through is not plagiarism, because the ideas, research and outline stay yours and quotes pass through word for word. If you publish for clients, our notes on client work cover what to check in the contract. Want a score on a draft as well? Our free AI detector gives you one.
