Semrush SEO Writing Assistant


The Semrush SEO Writing Assistant provides instant recommendations for content optimization based on the qualities of Google’s top 10-ranking pages for your given keywords in a given location. Content professionals, bloggers and marketing experts can check if their texts or the texts of external writers meet various content-quality requirements in just a few clicks.


  • Overall score – checks the article’s general quality calculated according to metrics such as readability, text length, and target keywords.
  • Readability score – evaluates your text’s difficulty based on the recommended Flesch-Kincaid reading-ease score. You will get recommendations for sentences and words that need improvement.
  • Target keywords – shows recommendations regarding the given keywords, their volume and their difficulty.
  • Recommended keywords – shows semantically related keywords, that should also be added to your text.
  • Tone of voice – make sure that your writing is consistent with the desired level of formality.
  • Plagiarism – validate that your writer has submitted original content.
  • Linking – check your links for possible errors and problems.

How it works?

  1. Connect or register a Semrush account for free.
  2. Set your target keywords to get recommendations for your content.
  3. Select a target location and device (desktop or mobile).
  4. Create an SEO content template.

Is it free?

In order to run the SEO Writing Assistant, you will need a Semrush account to create an SEO content template. With a free or Pro SEMrush account, you can create one recommendation set (tied to a document) for a lifetime. Higher tier accounts have different keyword budgets depending on the subscription plan, as well as access to the full power of Semrush Content Marketing Platform.

Also, if someone (e.g., your Content Manager) has already created SEO content template and connected it to a post, anyone who has access to the post will be able to see the SEO Writing Assistant interface.

The plugin throws console log errors (404s) in every post and page edit screen. Custom post-types have different console log errors and any custom post-type edit screen that uses AJAX results in varying degrees of failure to execute. Sometimes the AJAX function won't execute at all, other times it's just that the success response isn't processed correctly. We had to disable the plugin as it was conflicting with every custom post-type we have installed, all of which are far more important to the operation of the site than this tool is.

Even if you pay 99/mo which I have done for years you can't make use of this basic plugin as it's only available at guru level - good way to annoy your clients semrush - I will be looking for a replacement seo solution

You need the $199/mo Guru account in order to use the Writing Assistant. We have the $99/mo Pro account and it said we had to upgrade to Guru to use it. I don't want to give it 1-star because it might be a good tool, but the description said this could be used with a free account which makes this too confusing. I ended up uninstalling this plugin and just using Yoast Premium.

On the first page I edited it worked. Of course, like other tools they have a premium which I have no problem with. But then on the second page I edited, wherever I clicked it started forcing me to subscripe to 199$ subscription of SemRush. Maybe you should keep some features free of charge before trying hard to milk people! So we can test and maybe subscribe for more!
