There are two common ways to use an AI rewriter. One makes your writing better; the other gets your site demoted. The difference is not the tool but what you feed it.

Where AI rewriting helps

  • Polishing your own draft: fixing grammar, splitting long sentences, making it read naturally.
  • Changing tone: turning a casual product blurb into a formal B2B page, or the other way round.
  • Shortening: cutting a 300-word paragraph to 180 for a meta description, an ad or a social post.
  • Localizing: turning source material into a first draft in the target market's language, then having a fluent reader check it.

Where it hurts: spinning

Copying a top-ranking article, rewriting it and publishing it is the most common and least useful approach. In its March 2024 spam policy update, Google named "scaled content abuse": producing many pages to manipulate rankings without adding value for users, whether a human or AI wrote them.

The test

If the rewritten text adds nothing the original lacked, such as your own test data, screenshots, experience or opinion, it is duplicate content to readers and search engines alike.

Picking a rewrite mode

ModeGood forWatch out for
StandardNew wording, same informationCheck names and numbers
FluentDrafts by non-native writersSmallest change, safest
FormalSales emails, B2B sites, reportsCan get long and stiff
SimpleTutorials, product docsMay drop detail
ShortenMeta descriptions, ads, socialAbout 40% shorter; check key facts survive

A real example

Original: "Our tool helps you find keywords that are easy to rank for."

  • Fluent: "Our tool assists you in discovering keywords that are simple to rank for."
  • Formal: "Our tool assists in identifying keywords that possess a favorable ranking potential."

Formal mode made the sentence more businesslike, and also more convoluted. Short, clear sentences are often fine as they are; rewriting pays off on long, clumsy or ungrammatical paragraphs.

A workflow that holds up

  • Write first, even if only bullet points, and include your own experience and data.
  • Use the AI rewriter to polish or translate.
  • Read it through: check numbers, brand names and terminology, and cut filler.
  • Before publishing, ask what this gives readers that the top three results do not.
