How often is Quality Score Updated?

How long after I tweak landing page and ad copy does the Quality Score get recalculated?

 

Google updates fairly regularly. I see their bots on my site every week if not more often.

According to google, they update quality score at least once per month.

I believe if you add a new ad they will spider and reanalyze it pretty quickly.

 

I've been testing this over the past two days, I'm seeing the Quality Score updated every 2 hours for competitive keywords and daily for not so competitive terms.

Can anyone backup these results with experience?

 

Personally i see it updated ever 4-5 days !

 

Umm, how do you 'see' it?

 

Go into your adwords campaign and do the following:

 

This thread was asking about the landing page quality score, not the keyword quality score.

 

Now I'm confused. Isn't there a direct correlation between the keyword qc and the landing page qc and the ad copy? Aren't they all codependent? Hence the qc on the keyword is reprentative of the qc of the landing page?

I mean, someone could be stupid and make a high quality landing page about cars then bid on keywords like fuzzie dice.

Would a campaign with a low qc landing page about cars still show a "great" qc for the keyword cars?

 

There are other factors that go into keyword quality like CTR and keyword/ad text relevance.
