Do Link building Strategies to gain traffic

Good and useful content, post at forums, submit to good seo

For your topic, I'd try writing some informational articles and bookmarking them on as many social bookmarking sites as you can. People are always searching for how-tos on stuff like setting up home theater equipment.

Submit to the smaller SB sites along with the main ones like Digg, deli.cio.us, etc.
Those sites may get less traffic, but your article will stay on the front page longer, giving you more overall exposure.

good and fresh content and update frequently and post at relate forum , exchage links

post to classifieds... and continue on getting relevant links. also, always update your site for new products or services, in that way people will be interested to your site
