This must be a freaking monster mind in the plex who put that kind of joke. Really, it had to be a joke, a programmer joke, like if I was trying to workaround the system and I receive a punish instead!
Someone dares to try it just for fun?
I think I did it three times, so go and delete some inactive keywords and readd them, three times and see what happens...
This problem seems to be with newer client accounts, even though I use some of keywords are the same as those for other clients.
Today they have increased a Major portion of my keywords from below $1.00 to $5 - $10.
These are campaigns that have been running for LITERALLY Years!
This is Absolutely ridiculous.
My thoughts are they are trying to get rid of the Little guy -- anyone who doesn't spend $10,000 a month.
For example I have one keyword that has generated 34,000 clicks over the last couple of years, generating nearly 30k of for google. The CTR has been consistently around 3% while being ranked between 5 and 7 during that time. The min bid was raised to $10 today. Hard to fathom.
