This is an example of a 'definition' page for the word 'web', in the context of 'web design', 'web design services', etc, etc. Many search engines rank pages very highly if a particular keyword (i.e., in this case "web") links to a page that contains a lot of content containing the word web, such as web design, search engine optimization for websites,website design, and so forth.
Web design is good! :)
So one thing that this software gives you the option of doing is to go through your entire website that you create, and change a set 'percentage' of words to link to this page. I.e., "web","website","web design", etc. The search engine will then 'associate' these search terms with this page you are reading right now, so if someone does a search for say, "web design", the likelihood of your page being listed is significantly higher. If you have a number of different domain names (i.e., "mywebservices.com", "someotherwebdesignstuff.com", etc, etc), and then 'interlink' them, you can get ranked even higher in the search engines. Search engines also pay attention to the keyword present in the domain names.
Higher ranked pages mean more search engine traffic, which generally means more sales for you, because most people view "search links" as "legitimate" or "reliable" sources of information, as opposed to advertisements may be beside the search listings.
So anyways, if you found this page through a search engine, then you have just proved it works! especially for the word 'web' or web design, etc. And this page you can customize exactly how you want
