Overall Score

Once activated, the SEO Writing Assistant will provide an overall score whenever you’re on a page on your WordPress site. This score grades the quality of your content and tells you just how possible it is to rank on Google with such content.

This score is based on metrics like SEO, Readability, Originality, and Tone of Voice. You’ll also get to see the metrics affecting your score and ways to improve the score.

A score between 8 and 10 indicates that your content is well optimized to rank on Google. If you hope to rank on search engines you should always target an overall score close to 10.Before you can be provided an overall score on your content, you’ll have to create recommendations (target keywords, location, and device) for that content.

The SEO Writing Assistant uses these recommendations to give your content an overall score.


Readability refers to how easily a reader can understand the written text of your content. The SEO Writing assistant uses the Flesch reading-ease score formula to determine just how readable your text is.

On the readability scale, you’ll find metrics like the readability score, title issues, word count, and content issues. You’ll also be provided with a target score which is aimed at making your text more readable, thereby increasing the chances of the reader reading through the entire content.

Words: the number of words in your content will be calculated using the Flesch reading-ease score formula to determine. A goal will be set according to the average word count of your competitor’s content.

While this tool has a lot of useful features, it also comes with some flaws. The tool doesn’t clarify its target word count. Although it states that it’s based on an average of the top 10 articles (your competitors’ word count for the same content) on Google, there is more that should be done make things clear on how long your article should be.

Also, while you get a good number of recommend keywords to fit into your article, you don’t get any directions on how to fit your text with these keywords. If you’re a newbie to optimizing your article for SEO, you might find it hard to do so.

Still, SEMRush SEO Writing Assistant still remains a great tool for writing high-quality SEO content.
