When trading links you should manually review each site to see if the site is worth exchanging links with. I would never let a computer program decide who to exchange links with!
You don’t want to trade links with just any website you come across. When looking for websites to trade links with or when you get a request from a web master to trade links with your site, you need to do several things.
The first thing to do is go to the page that has their links on it and make sure they use static links to link to their link partners (see Links that Don’t Pass Page Rank ). If not, then it is likely there site will not pass Page Rank to your website, which means it will be of little value from a Search Engine ranking perspective.
Next, find out how you would get from the website’s home page to the page on the website with a link to your site. If it is really hard to find the page that will be linking to your site, then don’t bother trading links with them. A good rule of thumb is to make sure you can get to the link from the home page with two mouse clicks or less. If you have trouble finding their links page, what is the chance that other people are ever going to look at it?
The next thing to do is take a look at the website and see if it is a website that you believe visitors of your website would benefit from or be interested in. Don’t trade links with a site that has absolutely no benefit to visitors of your website.
After that, take a look at the websites that link to the site. If the websites that link to it are high quality / related websites then you know they have good link partners. If most of the websites that link to it are link farms, gambling, porn sites, etc. These types of websites often get penalized by the Search Engines, and exchanging links with too many of them could get your website penalized. So avoid trading links with these types of websites.
The websites you exchange links with should:
1.Have quality content.
2.Provide useful information that visitors to your website would be interested in.
3.Have a clearly visible, easy to find link to the page that has a link to your website on it.
4.Use links that pass Page Rank to your site.
5.Do not exchange links with link farms, gambling sites, porn sites, and prescription drug sites.
