Darren from Problogger was going on a business trip (so he says, I bet he just got drunk and had a party) so he asked his readers to email him some tips and tutorials. So that he can put a timestamp on them and they will automatically post when he’s at a party somewhere. This is not good just for Darren, but for the people that submited there tips and get good exposure. In my case my site had Pagerank 4 Prediction days before my article was put on Problogger. ( Predicted pagerank 4 (3.8) and 419 backlinks.
After gaining that exposure my Predicted Pagerank has gone to 5(4.9) with 1240 backlinks.
This is the power of exposure. I guess you could say exposure is a type of marketing.
