The best permanent way for traffic is search engine optimization. It takes some time to fine tune the SEO but it pays off exponentially.
The practice of exchanging links with other websites. You place another site’s link on your site, usually on a links page, and in return, the other site places a link on their site back to you. Link exchanges will get you some traffic coming from other sites but the biggest reason you want to do link exchanges is to increase your page rank.
