Never, blog commenting is not SEO. Don't listen to SEO advice from here. It is wrong across the board. There are about 5 people around here who actually know what they are doing. Nigel
Nice answer!! and if I may add to the OP - dude if you use English like that for comments - then don't expect results.
spamming comment will never get approved from the quality blog And those crap box never helps, it will only give signal for google to flag your site
1. Did you point these at your main site? They're better on your lower tier backlinks. (Backlinking your backlinks.) 2. Are they DoFollow? 10k nofollow links isn't going to do much. 3. Did the posts already have thousands upon thousands of other comments?
I agree with js projects if your using scrapebox blasts its better to use them for link 4 links.... and i dis agree with the guy above... there are more then 5 people here who know seo lol
are you telling that you've posted comments with the links on 10k blogs? and waiting for the result on your site's PR? If yes, it depends on the quality of the blogs, relevance. Google will look into the things. You can see the result in the next google update. Until then have a try using PR checker tool pagerank.net
