Spam like behaviour in Shop Search

[Ermitrude]

In the Search & Discovery app, I seem to be having some spam like behaviour happening in my search queries. Everyday there are multiple searches with a string of numbers (see attached screenshot). On one single day I had 258 searches of just these random numbers which all occurred at midnight. I don't know if this is the result of an SEO/Marketing app I use like Moz doing site crawls, or something more sinister but I have no idea to how to prevent it. If anyone has any suggestions, I'd appreciate the assistance.

Hi,

did you create this overview with Shopify's report tool? Or did you gather that data separately?

It is very suspicious to me, that all the queries ran at the same time and even on top of the hour. This does look like an automated system running a scan.

If you want to confirm this, you try disabling scans for a day on Moz if you are able to.

Do this numbers mean anything to you? Do they look like the SKUs that you use for your products? Are they found anywhere in your store or completely random?

Cheers
