I need your views on reciprocal links exchange sites. I have come across websites like Linkmarket.com and Exchanges.net that promise to be the best source to get good site PR. My business associate also told me that this is really a good medium to get a huge chunk of money every month. However, when I researched, I read that reciprocal link exchange is not a recommended service by recent SEO podcasts/tutorials. I also read that on taking advantage of the same, the site’s ranking in search engine will get affected. Before I dig my own grave, I want your suggestion.
