Recently, I figured out that joining a Traffic Exchange program can help your site boost traffic, especially if the program offers 1:1 traffic exchange.
1:1 traffic exchange, I mean if you visited one member site, it will be considered as one credit for your site to be visited too.
Of course, the visiting of the site will not be done by a manual clicking of the site, but it is better if it is automatically open under the host site.
So, if you regularly has 300 visitors a day, then through the traffic exchange program, it will be doubled into 600 visitors a day. Your regular visitor will be added from those visitor accidentally visited your site through this program.
