I have some very important top-performing keywords in one UK campaign pulling about 1.5%, which have been running happily for 9 months. I recently launched a different campaign for a different site and different product, targeted on USA this time, but using the same keywords.
This new campaign has overall lower CTRs, and some some of these good keyword are being disabled in this new campaign due to CTR below minimum. Fair enough. But :( I have just seen that the same keywords are being disabled in the old campaign, despite still healthy CTRs there.
Ouch! My Impressions and clicks on the old campaign has just halved!
Is this a real and normal phenomenon, or am I missing something here? It looks like Google is determining the keyword CTR for disabling purposes based on the CTR for all campaigns, not just for that campaign or adgroup.
Is there any way round this? The only one I can think of is to set up a new separate account, on whihc subject I want to start a separate post anyway.
If you're having other keywords disabled, odds are there is another reason for it, and you should contact G about the issues, although they are good about sending emails with the exact problem when a keyword is disabled.
Ewhisper: It *IS* the individual keywords being disabled; the problem is just that they are being disabled across more than one campaign, seemingly because of poor CTR in just 1 campaign.
Baazigar: I've now checked the keywords report - they get disabled on both campaigns on precisely the same dates. A keyword dies on the old campaign on the same day it dies on a new one. :-( No way this was caused by gradual improvement in the editorial SERPS.
