Although most SEO experts agree that having fully valid html and css are not prerequisites for perfect search engine optimization, we recently found out how it could bring us additional traffic: many blogs out there feature validated sites on their homepages.
These blogs have a large readership (mainly designers) and submitting to many of them can bring in hundreds of visitors to your website. For example, we submitted our website tocssdrive.com, which not only featured us for our site, but also for our menu design.
We have received over 2,000 visits from this site since BFM was featured on August 8. Of course, most of this traffic consists of designers - not exactly the kind of leads we are looking for in terms of new web design projects. But it is still nice to be recognized by other designers as a web design company that does adhere to W3C standards.
Here are some of the websites that brought us a decent amount of traffic:
8. CSSSnap.com (Note: This website recently got hacked by Turkish hacker(s), "Beyaz".)
Basically, the main challenge is to design a website that passes W3C validation. Then submit away!
