I want to change a domain name for my site, my domain name is http://www.atraf-f.net and it exists something like 2 years ~ I have something like 180,000+ pages that are indexed on google, and something like 50% of my daily traffic comes from google. I'm afraid that if i'll change the domain name i'll lose alot of my PR,TR I'm in top locations on google for some words(major), I've exchanged a lot of links, and this domain should get PR4-5 in the next update. I've used redirect 301 in an other site that i own, www.atraf-f.net/or every page at that domain will redirect you to the same page in the new domain and it's 301, and until now, non of the pages were re indexed with the new domain, this site is a forum, all the pages that are indexed with this new domain are pages that were indexed just after the we started using the new domain (new pages that were generated just after we moved a domain) What should I do? I want to keep all the SEO work that was done on my domain (atraf-f.net) and to move to a new domain name.
If you have done proper 301 redirect then you will not lose your ranking. whenever you you change your domain then make a sitemap and submit this to google or create new google sitemap account for the same.
301 redirects are not black hat. They are recommended by google to transfer sites. You should be fine as I have done this before with one site and everything transferred over perfectly!
