Post Updated CommentKahuna is now in Version 2.0
SEO used to be easy. Build a site, write some tags, submit it to the search engines and sit back and wait for loads of free traffic. Today it is not so easy. Now we have to go a stage further and build loads of links to our sites; but often not even that is enough. The search engines know about link farms and even article directories are not the force they were just a few months ago.
The guys at PortalFeeder know your pain. 
Today they have announced a new product called CommentKahuna and it is free!
Comment Kahuna is designed to help build back links that would stand the test of time and have immediate benefit.
When I started out building backlinks it did not take long to discover that using blogs was the way to go. Blogs are spidered fast and often so I could get new pages and sites indexed fast, so I started hunting out blogs and posting comments. This was good but something was missing…
It was still taking a long time to go through the process. search for blogs, find the comments, post a comment, rinse, repeat.
I was thinking there was likely a better, more automated, way to post comments to high Page Rank blogs. I was right, there is and it is ideal for folks who are using manual, or automated blogs (automated blogs).
CommentKahuna.
Here is how you build backlinks to your sites.
1) Choose your search term, enter it into CommentKahuna, input a username, your email and the URL of the site to which you want to link. Press the button and the magic begins! You can also choose what types of blogs to go for, WordPress, TypePad, MoveableType etc etc, a great way to increase the number of blogs to post to.
2) CommentKahuna searches out blogs with specific posts that match your search terms, it creates a list that also displays the PageRank (PR) of each of the posts.
3) You can filter out the lower PR posts and go for higher value links.
4) Now all you have to do is scan the post, and write an appropriate comment, paste in your site info, press submit in the browser window and move to the next tab.
Comment Kahuna will pick up anything up to 50 blogs at each go, probably 10 comments per keyword run is enough.
As a matter of course, I only ever post where I can add to the discussion in a positive manner and I am finding that back links from blogs are helping me to get spidered and indexed much faster than previously. Used in conjunction with Social Bookmarking one can have a powerful set of tools that make what was a laborious task almost a pleasure. The only serious drawback is that I get distracted by reading posts!
Anyway, for your backlink building pleasure just download CommentKahuna and get building.

EDIT and Update!
CommentKahuna V2.0 has just been released. The main change is that now CommentKahuna can identify those blogs that do not use No Follow tags on their comments sections. This is very good because now it means that as well as driving on-theme traffic to your sites you can also be sure that the link is carrying PageRank and thus enhancing your page’s authority. It also means that Google’s spiders can now use links to enter your new pages helping even more with indexing.
