I have just started managing a new account and it has thrown up some interesting dilemmas that I have not come across before. I have had to change the display url and the domain urls (destination and tracking) from say www.widgetstogo.com to www.widgets.com. I had position preference set and have had to switch it off because the ads have dropped out of the top 3 positions which I had it set to. What is the long term effect of this? For example how long will it take the history to catch up and for us to start to rise again? An additional question I have is this, I want to clean up the account and make the adgroups more relevant for example widgets for teachers, widgets for doctors, instead of just widgets aimed at everyone. If I set up new adgroups in current campaigns and copy across from the old adgroup to the new adgroup what affect will this have on the performance of the keywords/ads. Will I have a downtime of say two weeks before getting back to their current SERP or will we never get back to where we are now? We are in an extremely competitive market.
I changed my url and my ad never recovered. I read an article that it totally drops your quality score to change destination url. I jus thad to set up a new ad in its place.
