Guest Blogging Suddenly killing my rankings

I have been using niche guest blogging for some time and its always worked. 4 or 5 links at a time. Suddenly over the last few days, i'v noticed my rankings dropped a page! Anyone else experiencing this?

Rumours of an algorithm update/test are rife: https://www.seroundtable.com/google-update-20048.html so it might just be this affecting your rankings. But then, maybe guest blogging is something that they are trying to target again.

Have you dropped from page 1 to page 2 or are you lower down than this? The lower you are, the more fluctuation I typically see.

Ask the blogger to remove the links that he made... And see what happens... I think it's just normal Google dance... I haven't noticed any serp changes or updates..
