This time, there are more contestants that are competing for the grand prize of $1,000 and pf course, the "bragging right" to their friends. This SEO contest however helps the contestants develop their skills in SEO and the winners can use it for their portfolio.
But no matter how helpful the SEO contests are, in the ordinary internet users, those posts (just like this) in the blogs of the participants to support their entries, are just as useless as nothing.
