Read the whole idea behind the concept here <a href="http://www.prelovac.com/vladimir/presenting-seo-super-comments-concept" title="Seo Super Comments Concept" rel="nofollow ugc">Seo Super Comments Concept</a>
For each user comment we will create a new dynamic page on the blog, holding the actual comment information. This page will not actually exist in WordPress database, but we will create it dynamically using a WordPress plugin.
What we instantly get in this way is big jump in site’s index visible to search engines. This is possible because blog comments are crawl-able, index-able and most importantly rank-able content. Also meaning you will start to get search engine traffic for the context of the comment.
The old author link in the comments will now lead to the newly generated page. Author’s URL will still be displayed (and we can do-follow it now as it will be only one external link on the page).
The concept relies around optimizing the target page using title and H1 tag using the context of the comment. So basically we will take the excerpt of the comment and use it to create the page title and H1 tag and in the body we will old the content of the comment (plus some more goodies, read on).
Since now all comments normally drain page rank even when nofollowed (bad for your site) the whole idea of using them to generate links back to your site instead and get free indexable content along the way, looks just much more appealing.
To spice things up, the dynamic comment page concept additionally features:
<pre><code>* List of author's other comments on the post are presented (good value for the visitor, more content)
* List of author's other comments on the blog (even more content, chance to interlink to your other posts, more value to the visitor)
* Author url links are do-followed (option, but why not?)
* Extra few clicks generated will increase your pageviews, lower the bounce rate and increase any CPM advertsing revenue
* I have also created a mod for hugely popular XML sitemaps plugin to include all the new dynamic comment pages into your sitemap, so that the search engines can index the pages more quickly.
