SEO Tips: Link Exchange
Now I want to share my experience with you about link exchange. Before exchange your link, you should check the site’s PageRank, there are so many sites which can check Google PageRank(PR), the site I mostly used is www.checkpagerank.net; you can check whether the PR is fake or valid.
And then, you can use the commend ’site:domain.com’ to see the number which indexed by Search Engine such as Google. If there are just few numbers, then maybe this site is a fresh site or a fake site which just want to sell links.
The other commend is ‘link:domain.com’ to see the site’s link popularity.
