2 ads in the same campaign
I have two ads within the same campaign, how do I know how often google will switch between the two? Also is it a good idea to have them be completely different? Right now the only difference in the URL that they click through to, should I change some keywords as well?
Re: 2 ads in the same campaign
You should target adgroups based on themes, For example: Your campaign can be Televisions, then you can create Adgroups based on Plasma TV, LED Tv, LCD TV. For each of these adgroups you will have keywords targeted to the product or theme.
Google will switch between ads based on the Relevance of Ads and keywords.
