Every Friday the Impressions Spikes up abnormally , but the Click rate still the same or even fewer than the previous day, I have checked all Crons job , the server , Weekly Keywords Checker (like Semrush) and google analytics but nothing seems strange each Friday. We was using Semrush before, and we stop it and blocked their bots, to see if they causing the problem with no chance. website: wordpress platform main plugins may causing the problem: yoast
the website is about Inventory System and Asset Tracking. https://asapsystems.com/
the queries and pages on spikes day and the previous day:
so it seems like the "warehouse" keyword is the main reason of impressions, but in all other days it doesn't have that high impressions.
for the devices and country
US - 10,653 - 3,209
Desktop - 15,794 - 8,747
and for the Search Appearance is the same for spikes and other days.
Any suggestions or explanation . and how can I stop this impressions peak?
