Yep, it can happen - "Google dance". Did you also edit your pages (like change page builder)?
Give it a week or two and see if it bounces back.
Okay.No, only I changed the theme, rest are all same.
Okay.
Is the internal linking different? For example, if you didn't use sidebars/certain links in footer - and now it's changed with the new theme? But either way, just changing the theme can have those effects, so just wait a while or switch back to the old theme.
Alright, well give it a week or two (if you want the new theme), or swap back again and see if it helps.Nope, same internal linking. I saw all the links and sidebar are intact as before. Some of the keywords are dancing in page 2 to 5 or nowhere.
