It's important to note that all SEO on the Mending Kids site is organic. They wouldn't use AdWords nor would I recommend it for them. For that matter, I wouldn't recommend it for your site either. AdWords is great for a business that serves the world, not a region. You would have to severely limit your campaigns to niche websites, and or discussion groups in order to be effective for only a region.
All you need are unique page titles, unique descriptions, a < h1 > or < h2 > header and compelling opening paragraph for each page to be effective with search engines. Keywords in your html are useless nowadays. It's better to use keywords in your page body and crank up the frequency by which they appear across the site.
