AI content optimiser

The tool scores a draft or existing page against top search results for a target keyword and suggests changes to terms, structure and length to help it rank.

What it is

An AI content optimiser compares your page with the pages that already rank for a keyword. It looks at the topics covered, the terms used, the length and the headings, then gives a score and a list of suggested changes. You can often work inside an editor and watch the score move as you edit. For example, it might suggest adding a section on pricing questions that most ranking pages include. Ahrefs, Clearscope, Frase, Otterly.AI, SEMrush and SurferSEO are listed as having it.

Why it matters

It helps writers cover a subject fully without guessing, and it gives editors a quick way to review drafts. It matters for teams publishing many articles and for refreshing old pages that have slipped in the rankings. A high score does not guarantee ranking, and following it too closely can produce stiff, repetitive text. It matters less for pages whose value comes from original data, opinion or brand rather than keyword coverage.

What to check

  • What does it compare against, and can you choose the country and language.
  • Does it work on drafts as well as published pages.
  • Does it explain its suggestions, or only give a score.
  • Is there a limit on the number of pages or articles you can optimise on your plan.
