I would assume it uses keywords but I really don’t know. I am a non-techy person.
The Yuzo plugin is fantastic on the blog side. My site has been live since 2005. I write daily and the plugin reliably pulls up relevant content. It’s astonishing good at discerning what to feature. This is why I mentioned Simple:Press rolling into wordpress. I’d rather keep the forum “related content” separate from the blog side but it gives me hope.
This might give a clue

I really hate the all the content on the forum side is inaccessible for the most part.. or at least it was until Google started indexing it (again) pretty aggressively. But helping the user with “related topics” would be ideal.
Just putting my ideas out here… there is another forum site, like mine in that people go there to visit, commune and discuss and such. They have a lot of content and they offer access via a two tiered search (that is very good).
You have the option to search recent content (maybe the last 30 days or so). But if you want to search the entire archive you can do that as well. As a user, these tools work well enough. They satisfy.
The Simple:Press search has never been effective (sorry). Google search (custom, which is on my site) fills in. But you see what I’m saying here. It you want to amp up your product, this will do it.
To try to answer your question about where to place the links, my old plugin, to the best of my recollection, make them prominent.
It was a simple bullet list.
- other topic
- related thing here
- another interesting thing to read
Three or four suggestions would be plenty. I guess the logical place to put them is at the bottom of the page. You read everything and then click to something else that catches your eye.
You can see how the yuzo plugin looks.. it’s pulls in the featured pics. But frankly, the FUNCTION is the most important thing. The bullet list worked beautifully.
Just to wrap up, the other user on this forum mentioned that he was using Simple:Press for mini-blog posts due to the google situation at this time. I am doing the same thing. I did not have a name for what I was doing, but I have caught on to the fact that I can post in the forum and be seen.
So basically, these forums that are “dying”? They’re not. They are coming back strong at this time. And right now, I can get the user to the site via google. With a related posts plugin, I could keep them there…
edit to add..
here is another possible source of info
