How important is it to have the Landing Page TitleHeadline Exactly match the Keyword for Google Quality Score/SEO Benefits?
If the Keyword is: Austin Homes
Can the Title/Headline be: Austin Texas Real Estate, or Austin TX Real Estate, etc.?
I assume the name of the Community/Neigborhood should match as opposed to simply relying upon the Major City's name?

Also, does having Links from the Landing Page to different Community/Neighborhood Pages work as well from a Quality Score/SEO standpoint work as well as having a different Landing Page per Community/Neighborhood?

And for SEO purposes, would it be recommended to start with the Larger more Competitive Communities with more traffic and higher bids, or the Smaller less Competitive ones with less traffic and lower bids?
