Practice is testing our SEO knowledge daily but how about a quiz with some easy, some difficult, and some very difficult SEO quiestions? The reward for performing great at the quiz will not be the first place in Google but if you know a lot about SEO and can think creatively, the first place in Google is within your reach.
Please, take your Black Hats before starting the quiz. Your Black Hat will spoil the fun of having organic results at the quiz! Even if you don't get the highest possible score, there is no reason for drama!
Wish you luck and have fun!
