Can I check the SEO of a content that was already written?

The SEO Writing Assistant is an AI intelligence capable of correcting any text. You can either write content from scratch directly on the editor or paste a content from another text editor. You can also refresh old content that was not created for SEO.

Why is my score on the SEO Writing Assistant different from the content score on the page analysis?

Contrary to the on-page SEO checker, the SEO writing assistant only takes into account what is written on the editor. It does not check for aspects such as link anchor, button texts or alt attributes i.e. If you also want to check for all these aspects, we recommend you to start writing your content on the SEO writing assistant and once it is published, you can run a page analysis.
