How the Writing Assistant Scores Your Draft

The tool works inside your editor as a sidebar. It shows a score out of 100 for SEO, readability, originality, and tone. Each score updates as you edit.

You set a target keyword, location, and device before you start. The tool then pulls data from Semrush’s database of top-ranking pages for that query. It recommends adding or removing certain words, adjusting sentence length, and matching the tone of competing content.

The score is a guide, not a guarantee. Google does not use this score in its ranking algorithm.

  • Set your target keyword and location first, or the recommendations may not match your intent.
  • The tool highlights specific sentences or paragraphs that need improvement.
  • You can ignore any recommendation if it hurts the natural flow of your writing.

Where It Fits in a Content Workflow

The Writing Assistant is part of Semrush’s Content Marketing Toolkit. It often works alongside the SEO Content Template, which provides a starting structure based on top-ranking pages. Many users draft in Google Docs and check the score there before moving the text to a CMS.

I use it after seo keyword research to make sure the draft covers the right terms. It also helps during what seo blog writing means by flagging readability issues early. The tool is not a rank tracker; it is an editor that helps you align with current search patterns.

Limitations You Should Know

The recommendations change often because Google’s top results shift. A score that looks good today may not help next month. The tool also relies on Semrush’s own data about what ranks, which is an estimate.

If you set the wrong keyword or location, the tool will suggest irrelevant changes. Always double-check the context before following suggestions.

  • The originality check compares your text against a large database, but it is not foolproof.
  • The tone recommendations are based on competitor language, which can lead to unoriginal writing if followed blindly.
  • The tool does not replace a human editor for nuance or brand voice.

How It Compares to Other Content Tools

Semrush’s tool is similar to Surfer SEO and Clearscope. All three score content against top-ranking pages. The main difference is that Semrush bundles the Writing Assistant with its broader suite, including Semrush Keyword Research. Semrush pricing is separate. For a comparison of two popular alternatives, see clearscope vs surfer seo. The Writing Assistant is a good choice if you already use Semrush for seo tools and want an integrated editor. It is less useful as a standalone tool because it depends on Semrush’s keyword and SERP data. To understand how content optimization works, see how content optimization works.

Common mistakes

  • Treating the score as a ranking guarantee You may publish content that scores well but does not rank, because the score is only a drafting aid, not a Google signal.
  • Optimizing only for keywords and ignoring readability, tone, and originality The content may read poorly or duplicate competitor language, hurting user engagement and originality.
  • Using the tool without setting the right keyword, location, or device context Recommendations will be irrelevant or misleading, wasting editing time.
