Taking advantage of old links

Hey guys, I am currently changing one website entirely, and that includes switching scripts from joomla to wordpress. The problem is that I already have about 15.000 google indexed pages, some of them even carry pagerank. What is the best way to use these links in raising the serp and pagerank of the root page?

Is a 301 redirect okay, what code should I use and were?

Thank you.

 

As long as the links to the pages remain the same, changing from Joomla to WordPress won't do anything. If the link paths do change, use a 301 redirect on the root .htaccess file for each page you're redirecting. The code looks like this:

Redirect 301 /webpage.html http://www.domain.com/newwebpage.html

Code (markup):

Note this has to be done for EVERY page on the site.

 

Damn that is really annoying to have to do it for every page. What would happen if you just redirected everything to the new root?

 

Thank you

That's my dilemma too.

I was even thinking of redirecting the entire website to a new domain with just one 301 code line. How effective would that be ?

 

Then everything points to the root, which will likely tick off your users, causing them to leave.

 

Is that seen as SPAM in any way by google, or I don't need to worry ?

 

Depends on the intent and the number of redirects. It could be considered grounds for a manual review though.

 

You should be more concerned with maintaining the current serps if you are changing the url's.
