I have an adgroup with 3 different ad texts.
I would assume that some keywords have better quality score and perhaps better CTR with one of the ads.
Does Adwords match which ad they pick to show with a particular keyword with some logic to make the Best Match? Or is it somewhat random?
Some of my groups have only two keywords in it (the keyword and its plural). This way you can run specific ads per keyword and see which ad works best with that word.
Too bad I can't even create a new adgroup today.. those google balls just keep going back and forth across the page..
I'm having a little bit of success since last night i broke one adgroup into 7, focusing the keywords - much better positioning and slightly lower bids...
perhaps I've hit my ad group limit :(
First, in your campaign settings there are options for how Google will serve ads. The first is where Google starts to show the better preforming (by CTR) ads more often. The second is where the ads are rotated equally.
Secondly, if the AdWords system is being slow to create new ads and move items around; I'd suggest trying out the AdWords editor. It's much faster to make a lot of changes in the editor and then just upload everything once it's organized.
I am reminded of the old business adage: "I know half my advertising dollars are wasted - I just don't know which half." With Google, theoretically now a days we know which half, but on some of these things I still do not know.
One thing to keep in mind with the ads optimization feature is that existing ads with established history will not be immediately dethroned. If you have an ad that was the best of your initial batch and is serving at 90%+, when you add that new creative and it begins to perform better, it will not immediately jump to top percentage served. The older creative still carries a lot of weight because of its history as 'the best', so the new creative will begin slowly to eat into that served percentage.
