Because your articles (all the text you have on your site including testimonials if you have some, product description if you sell something, the information you have) are full of keywords related to the subject of your site

The best and easiest way to do mobile websites is to use a website builder software that already has the Mobile SEO App built into it and all you have to do is just click on it and it will optimize your site for mobile phones automatically.
