Domain name changing for the 3rd time !?

Hi

i have some questions please about changing domain names and redirecting effect on the SEO and ranking of forums,

in 2008 i had created my phpbb3 forum (www.firstforum.com), then in 2010 i had changed the domain name but this time i used vbulletin4+vbseo and i had successfully redirected all trafic to the new one (www.secondforum.com).

now i want to change again the domain name (www.thirdforum.com) of course i am using vbulletin4+vbseo², i think no probleme will be because i will not loose any trafic (redirections).

my question please is the next, is that changes on domain names will affect the seo/ranking of my new thirdforum.com ? and what i should do after changing this LAST domain name ?

thank you vbseo team you are doing a best job with this great script

We don't advise that many domain changes as each domain change will reset your rankings.

each domain change reset the site ranking ! this is the last change i do
now what i must do to change the domain name successfuly please (redirections, ..) ?

Assuming you are keeping the same database, you can simply park the old domain on the new domain, and make sure you have your redirects in place as per:
[How to] Setup www.yourdomain.com or yourdomain.com (www vs. non-www) - With .htaccess 301 redirects - vBulletin SEO Forums


If you've change the DB at all, it's a manual effort.

Still, as Mert points out, you'll still be starting over from day 1.

no i will keep my old DB, it will be more hard to redirect then
i will contact the support to help me to customize and repair my htacess.

i will restart all from 0 but this time is different
thanks men
