Yesterday I was seriously thinking about making some tweaks to links & on-page text. I decided not to do anything, just left everything alone.
I just checked a few keywords on this category of pages & images, everything bounced right back to it's old SERP positions.
What had me scratching my head was, Google only messed with 1 category of pages/images, my other categories of pages/images never budged in the SERPs. It looks very controlled how it all bounced back to old SERP positions.
Anyways, glad I left everything alone & waited it out.
