How to maximize the effect of surfing for credits.
Those sites you are seeing can be clicked on without loosing the surf bar so go on toutch them they don't bite. Now while you are at it here is how to increase your effectiveness while surfing for credits.
Comment systems
While serfing for traffic there are a number of things you can do to maximize the effect of your surfing. A little interaction goes a long way. A well thaught out comment is not only encouraging for the site owner but good for you too. Many a friendship or long lasting fandom was built by friendly message.
Tag Boards - Use them or loose them.
A tag board is s dmsll area usually found in the side bar or margin of a site why people can post comments. It is like a mini chat room in many ways. Often you can have you name be a link to something. We suggest your site might be a good thing to be linked next to a good positive comment.
BlogLinker / Blogroll
Swap links if you can. This useually causes a return visit.
Guest Book.
Always sign a guest book and don't forget to mention Mad-Den Traffic (and your own site [duh]). Say something nice to show that your not just spamming. I always try to spot something I feel I can comment on before I click.
Conclusion
By letting the site owner that you are there you are showing them that their site was OK. It makes them feel good and if a site owner was made to feel good by a visitor thay often go visit the visitors site. Some times more than once.
