I've a quite big vBulletin forum, with 400'000 messages and 15'000 users. Now I want to disable the vBulletin CMS and install Wordpress in the root of my domain.

So I'll move the forum in a folder (mysite.it/forum/) or in a subdomain (forum.mysite.it). Which is the best solution according to your experience? What do you suggest me to do? Thanks.

  • It is about your preference of how you want your website structure setup. You can have it eithe or and a combination of both.

  • @Fluorocarbon what about SEO, according to you? Commented May 7, 2014 at 8:28

It depends if you want to keep your page-rank for SEO or not. If you switch to a subdomain you will get a huge hit on your PR as subdomains are treated separately from main domains.

For this reason, I would have it in a subfolder. There is no one stopping you from doing a 301 redirect from subdomain to subfolder, so you will be able to access via both.

  • hey, thanks for your reply. I'm trying to study the best solution possibile for SEO. I made some research on google and I found that people are suggesting to use a subdomain for seo reasons if the forum is quite big. Now you're suggesting me to use a subfolder, so I'm totally confused :D Let's assume that I'm starting from 0, and my forum has 0 messages and 0 members, would you suggest to put it in a subfolder or in a subdomain?

  • You have to keep in mind that these people's suggestions are for creating a new forum. You already have your forum on main domain with PR etc., thus moving it is a bit different. You still need to think that you will need to redirect all the old URL's to either a subdomain or subdirectory URLs if you do not want penalty.

  • Yes I've tried to think to a way to 301 redirect my links, but unfortunatly I don't think that it's possible. This is where I explain the problem: stackoverflow.com/questions/23510647/… I can create manual redirects for the 300 articles I've on vBulletin CMS to Wordpress articles, but about the forum I think that the only possibile solution is to 301 redirect only the most important topics and category. Really I don't know what to do, but I'm forced to move from vBulletin CMS to Wordpress as I think that VB CMS it terrible for SEO. Commented May 7, 2014 at 11:38
