For a good ranking in search engines especially in Google links from other websites to the own site are very essential. There are several types of links and it is always good to understand something about it.
If you find a site with witch you want to exchange links contact the webmaster and offer him a link from your website. You get a backlink pointing from his site to your site if he agrees. Because both websites link to each other there are Two Way Links or reciprocal links. Keep in mind to ask for a link from related sites, they are more important to Google. Look for links from your competitors, they are most related. But you don’t want to advise the product of your competitors, you would rather sell your own one. more..Getting Backlinks
