I don't mean to criticize Kunena, so please do not receive my feedback as so as I find it to be the best forum solution for Joomla!.
What I am noticing is that I have just about an equal amount of pages published in Joomla! as articles. Then I have an almost equal amount of pages published in Kunena. I use my forum for lots of resource articles regarding theology.
The pages published by Joomla! are the backbone of search traffic coming inbound - organic wise. The pages published by Kunena receive only a fraction. I am not an SEO spec., the extent of the SEO that I have done to Kunena out of the box is using "no number rereplacer" out of Joomla!'s Jed, which allows me to search for all "no follow" attributes and replace with nothing, therefore making it as close to Joomla! as possible. The traffic, however, is nothing like the published pages in Joomla!. I'm using different content for the different components so I don't have a fair assessment regarding which is better, or where the problem may be. All I know is that SEO has come a long ways in Kunena in the last year, mainly with the meta descriptions which were duplicating because of the sequence in which the meta generators generated topic descriptions in the past.
My last comment is a suggestion. I realize that Kunena is a small team of dedicated "engineers" on the project. I would really like to see an overall thorough assessment done regarding SEO, which in the end could be used to help market Kunena. As a suggestion I would donate if your team would consider a donation drive for the specific purpose of developing the SEO, perhaps a banner along the side to select donations to develop SEO? By the way, I try to donate each time Kunena does an update already, but I am sure that additional funding would be an incentive for the team to further investigate this, or at least it would quiet the critics regarding it, since SEO seems to be such a black art.
Thanks
(Many thanks, too, for your financial contribution to the project - sozzled)
