Hi Friends, how do i know my site back link or links are valuable/worthable.I have been doing link building since 5months and adding/loosing/adding back links, but i am unable to find which one is valuable one way (Free)back link...really appreciated for earlier reply
Look at Google Analytics at the referring site URL and you can see which ones actually deliver traffic.
Here you can find 29 backlink checker and analysis tool from different sites. Of all, my favorite is Yahoo Site Explorer. If you want to find quality backlinks, try to comment on high PR dofollow blogs because most probably the latest contents on high PR dofollow blogs will gain good page's PR in next google PR update. Other than that, you can start digg and submit bookmark on dofollow bookmarking site. Submit your blog post to high PR and dofollow social bookmark sites. Remember, google only gives credit to dofollow backlink, either for paagerank or SERP ranking in google search engine. Now, I guess have some idea on quality backlinks.
Everyone say how important dofollow blog is but the real problem is how hard to find out it in the very niche. My strategy is post comments on google news results everyday and collect any qualified site.
