Hi Pet Vet,
A few more things to think about:
Match type does not affect your quality score. (If you look at your
example, you will notice that the broad, phrase and exact match of the
keyword all have the same quality score).
The question then is, why does ‘keyword’ have a lower quality score
than ‘keywords’? I would look to see how many impressions each
keyword has. From the data you provided, I want to guess that
‘keywords’ has more impressions than ‘keyword.’ If this is the case,
it may just be that the system needs to gather more information on
‘keyword’ before it can make a statistically significant determination
on the quality score for the keyword. (Until it has enough
impressions, the system will use performance data for ‘keyword’ across
all AdWords accounts. If ‘keyword’ has historically performed poorly,
then the keyword will start with a ‘poor’ quality score until you
accrue enough impressions to change the determination).
Hope this helps…
