@ohnoo_not_her Yep, that's the one... Diane also wrote a WA blog post, probably within 1-2 days of my one, which provided a tutorial of how to do this with GA4.
The easiest thing to do is to take one article at a time, do the checks in GA4 for the last SIXTEEN MONTHS, this way you can obviously check on how articles were doing prior to September 2023 HCU, were they affected by HCU, and how they've done since.
If an article wasn't getting traffic or ranking BEFORE HCU then it's "useless" in GOOGLE'S EYES.
BUT
Something I have kinda changed my mind on over the last couple of years (things change in SEO, therefore so does how I view things) is whether to delete an article simply because it isn't getting any "Google Love".
Obviously, as SEOs we have been heavily focused on Google for over two decades now, but realistically, if you think an article is well-written and helpful in YOUR MIND, and you think that your audience would benefit from it, then is it really worth deleting?
Perhaps it isn't getting any "Google Love", but you can still promote it to your audience, build foundational backlinks to it, perhaps even find broken links on competitors sites that can potentially backlink to it (this is covered in one of my tutorials in the "Private Coaching Group" I will be starting), or even performing outreach to competitors to see if they would like to link to the article based on some of the content you have found on their site (again, covered in a different tutorial for the "Private Coaching Group").
However, if you feel that the article was written "solely to rank in Google", and that you have other content that kinda covers some of the same factors, then you can delete it.
Furthermore, if an article is not getting any "Google Love", you can actually update it and potentially target a slightly different keyword or topic (yep, you've guessed it, covered in another "Private Coaching Group" tutorial, hahahaha!! Can you tell I've been busy over the last month or so, LOL)
All I'm saying is, don;t simply delete an article because Google appears to "hate it", think about the above first!!
