Feedback on SEO tool for Google's latest algorithms - idea stage

Keywords are dead!

In recent years Google have been moving away from keywords towards semantic search and question answering:

Many of the old keyword tricks are ineffective. The semantic meaning of content is now key. But how can webmasters understand whether their content is semantically similar to a search query? (in Google's eyes)

We know what AI they use

We know, from published material that behind the scenes Google are using a form of AI known as T5 (actually MUM which is derived from T5). We also use T5 for our platform so...

Let's test using the same technology

What if we enable webmasters to test a query against their content using T5? “See your content, as Google sees it”. Webmasters would be able to evaluate how semantically close their content is to a given query.

Of course we don’t actually know the ranking signals Google use, just the underlying technology. Nevertheless I think it has to be an improvement over all the keyword analysis tools still out there.

Thoughts?
