Hi I have been full member for link market.com site, where i do link exchange for my site http://tech.ittechsolution.com, when google did not give any page rank for this site, i was worried, when i discussed with one of my friend he said that back links are not a quality ones,so google is not indexing. Now i would like to know how to check a good quality back links ?
Quality links are the links which should match your site theme. They should have high PR. Links from irrelevant pages is waste of time. One quality link from a authoritative page is worth than 100 links from ordinary pages.
try making a subdomain and use that to link back to your reciprocal linkers and nofollow all links to the subdomain
Try to use yahoo site explorer. Otherwise, you can choose any one from 30 backlink checker and analyzer from http://atniz.com/2009/03/20/29-backlink-checker-and-link-analyzer-sites/
many people have different opinions on the quality of the backlinks. But in general, the value of page rank of the linked page, the relevancy of two pages and how did other webmasters link with your site. direct link , through redirect or? When doing link exchange, you should find a site that Google always has a recent cache, otherwise you may just waste of time because either the site is too new or they did something bad or for the websites was frequently down. But it is just my opinion.
