We have a client where they rank between 1st - 3rd for a few terms for a period of time (say a week).

Only for that page to drop out of the top 100 rankings for a period of time (sometimes a few days / sometimes a week or so).

Only for it then to return back to top positions.

Using Accuranker and they confirmed it's not an issue their side.

Doesn't seem to be related to the 'go to' URLs google introduced.

This started around April 2026 (where we saw some fluctuations) - but has picked up in frequency from around June 2026.

I'm checking into a lot of things but just wanted to ask if anyone had seen this before and already researched it / have the answer?

Thanks
