The only thing worth looking for is dofollow search engines. There are some software like market samurai and web ceo that might help you find the websites that are ranking well. However DO NOT try to get software that spams your comments. Google has said it will start to come down hard on Blog spam, so don't get caught up in it.
Try to find out the do follow blogs manually for punting your comment because software oriented work always gives the negative value to your site in terms of SEO.
Personally i don't think software works to find out some blog in which we can make some comments, anyways you can search by Google.
ScrapeBox is relatively easy to use and is the most successful piece of software that can comment on Blogs automatically. But, it has an extremely low success rate - just like every other piece of software out there. Whether your comments stick is down to the proxy you use, and the comments themselves. 95% of WordPress Blogs have got Akismet installed; if your comment looks like spam, it will be deleted almost immediately. My advice would be to do it manually, but focus more on building links from Web 2.0 Properties such as Articles on Article Directories and Forums. All the best, Lynn.
Don't ask for any kind of software for submission purpose in SEO, because they only create spam for your website. Search for dofollow blogs on Google about your niche and post comments manually.
Yes of course there are a lot of software for blog commenting in the market, but these are not for a long time, these are instant, I think so. here I would like to say that do it manually, if you don't have much time, hire to someone.
link building should be done all the time as long as you have your website, Its a time consuming work and would give you the benefits if you work on it long term manually. Better you can hire some guys with a monthly budget, that should do the work for you.
New blog spammer in town . Forget about blog spamming software as it won't help you... google and others will quickly find your spam and ban your site.
I have heard Comment Kahuna finds blogs for you and you have to manually comment on them. But please don't spam. You'll just waste your time.
