Besides installing vBSEO and other hacks I've been playing around with other things that enhance both SEO and the user's experience.

Wanting to find a way to automate the addition of a text link using keywords I thought of making the thread title in the postbit into a link. I coded this so that only the title in the first post would become a link, which avoids having everyone who writes a new title in a reply becoming linked.

Here is how I went about adding this. In my postbit_legacy template I found:
Code:
<strong>$post[title]</strong>
I changed this to:
Code:
<if condition="$post[postcount] == 1">
<strong><a href="$scriptpath">$post[title]</a></strong>
<else />
<strong>$post[title]</strong>
</if>
Not sure if I coded that correctly, but it seems to work. Now the first post title of every thread is linked to the thread, while all other posts with titles are left alone. I also added a css class just above in the <div> code to eliminate the link decoration (underline).

Here is a post on my forum as an example. The title of the first post is a link while other titles in later posts are not.

If anyone has a reason why this is a bad idea for SEO I'd like to hear about it.
