It seems like whenever I create a new ad it results in an initial really high CTR and then levels off the second day. My ad rankings don't really go up because I already have top 1-2 positions so that should not explain this temporary significant CTR increase. Just curious if you typically see a huge CTR improvement, temporarily, when you create new ad copy versions.
And I'm wondering if this works, albeit for only a day, why not do this every day for your best ad groups?
