I like that they do work with me to build my site, not just put it up for free or charge too much! They have done some great SEO stuff but also made sure we had content as well so people could find what they were looking for when visiting us online - which is good because before this there was very little traffic coming in from Google searches (at least none at all). As far as marketing goes I don't think any one thing really stands out though. It seems more about making connections between brands/websites than getting direct results themselves. The benefits are mostly indirect ones such as building your brand reputation over time rather then having someone else spend weeks doing nothing other creating an account etc.
