How Does It Work?

The SEO Writing Assistant add-on allows you to write, assess, and edit your content in Microsoft Word.

To set it up, click “Install”. If you haven’t already, you will be prompted to log in to the Microsoft account associated with your Word subscription. You will be notified once the installation is complete.

To start using the add-on, open a Word document. Under the “Home” tab, you will see a “Show SWA” icon. Select this and the add-on will pop up on the right hand side of the document.

Limits

To use SEO Writing Assistant, you need to first specify your target keywords. This requires a Semrush account.

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 full access to the powerful Semrush Content Marketing Platform.
