I have a website with around 3000 indexed pages in google, and for many keywords i'm in top results of Google. But for some important reasons i want to change my CMS, and obviously all my URL will change. What would happen to my position in Google ? how can i manage it to retrieve my position ? Anyone has similar experience ? (Domain will remain unchangeable, but URLs)
Hi... I would like to let you know that when you will change your CMS, it means you are going to change your "Data Base", not the url of your site or it's pages. So don't think about that. Any url will not be affected by doing this. And one more thing I would like to add here that it would not affect your rankings in GOOGLE, YAHOO or MSN....... Enjoy the moment.... Cheers....
The only way to maintain those positions is to 301 redirect every single URL that you have indexed now to a new URL. It could also impact your rankings if you have an internal link structure from those pages and your new CMS doesn't have it. If anything scrape all your urls indexed in google and redirect them to your new homepage.
As said make sure you have somethign in place to 301 rediect your urls and you should be OK - What CMS software are you changing from/to and how are you moving the data some CMS packages have built in functions to do the redirections automatically.
Not this. This. If you're links in Google suddenly go to a 404 page they will get dropped from Google after some time. Also all the links linking to that page will be lost as G won't go to your site and determine what links went where, that's up to you and 301 is the way to do it.
You have to make sure the new urls are matching the old one, or need 301 redirection from old to the new matching url's
