I have been running this Adwords account for 4 years and since two months the amount of traffic from this account (2000+ keywords) has been steadily declining. The Quality Score and AVG position remain unchanged. I have been changing the keywords bids here and there but mostly bidding up.
Also strange is that the same is happening for international (English) campaigns as a few Dutch campaigns I'm running. Has anyone else been experiencing this problem with their Adwords account?
