I have encountered a problem: Google Merchant Center has started rejecting my products, supposedly due to a 500 error, even though my server is very powerful.

Excessive Traffic to Web Server
by mitchb2992·6 months ago·1 reply
I am skeptical, on the face it looks to work well, but since I installed it, the https traffic to my website has increased 1000% which is flagging issues with my ISP. I can’t quite put my finger on it, but I also suspect that this might be a bit too good to be true – I wonder if there is some suspicious work being done through this plugin to fabricate the results, which seem inconsistent depending on when you run Page Insights…
