Re: quality score
What you're seeing are "baseline" quality scores. Because of past performance in your campaign or the campaigns of other advertisers, these keywords have low initial or baseline quality scores.
There are many discussions about improving quality score here in the Community. You can search by typing into the 'Ask a question' search box.
Here are links to some with useful information:
