Suddenly very high (30x) CPCs for a long term FB Ad campaign

Hey everyone,

In my Facebook Ad account i got a few CPC campaigns, all targets very large audiences on both instagram/facebook to promote articles on our web site. I’ve been using them like this with sometimes minor, and sometimes major changes.

I was usually getting 0.10-0.15₺ CPC and it’s been going like that for very long time. Yesterday, i increased their daily budget for a small amount and today CPCs hanging around 2,5-3,5₺. It’s really weird and i’ve never experienced something similar.

I checked change log and didn’t see anything besides my little budget adjustment.

Anyone experienced something similar or have any idea?

Thanks a lot.
