Search engines are getting smarter and smarter - it's no longer a matter of spamming keywords to get better rankings. They look for different things, particularly keywords scattered throughout.
The idea is to increase the relevance of your site. A lot of that can be done by modifying the content, but there's also a lot that can be done behind the scenes (in the code), and that's where we come in.

By tweaking your code here and there and adding some metadata, we can considerably improve the rankings your site would have otherwise achieved.
