Other than adding hundreds of new keywords to the new campaign, I did not change anything else, including Max. CPC, daily budget and ad copies. All remained the same.
But after a few days, I notice that the impressions have dropped significantly compared to the previous campaigns. It's not even half what it used to be. (CTR is slightly better, however)
Is this normal? Does Google put all your new campaigns in a slow mode first before going to full speed? Why do I get lower impressions even though I have the same exact keywords? I need an explanation for this before my client thinks I screwed up his campaign.
Thanks.
Also you will be starting over with new CTR for the ads so if you did have a high CTR with the old campaigns, then you will probably be appearing lower in the listing and/or paying more until the new keywords build up CTR percentages again.
