Erasing your keyword history

We all know some of our adverts get disabled due to a poor history. Well, is it possible to erase that history by creating a new Adgroup and putting the same keywords and a different url in there? Will this effectively scrub the history and start again?

 

Quality Score is at keyword level and stored history at account-wide level.

If you will put a different landing url at your ads you do not need to create another adgroup.

I would create another adgroup to erase the impressions and click statistics but this will not erase the quality score.

If your new URL has a better relevancy this will reflect in 24 hours the quality score.

 

When you say stored history is at account-wide level, what do you mean? Where does Google state this?

 

If you have a keyword inside a campaign with a certain quality score and decide to add/copy/move the same keyword to another campaign the quality score history data will be the same from the previous campaign.

I already tried all kind of tricks to reset a quality score. Also the documentation made a reference of inactive keywords (low Quality Score):

 

That's interesting. This suggests that if you delete your inactive keywords, it would improve the results of the active ones.
