ok, scenario: site A and site B are identical except the URL. site B is my new site now, site A is depreciated. I put a 301 redirect on site A, so every access goes to site B. Do i get any penalizations...eg. does google crawl the old site B, gets redirected to A and now A is penalized since google thinks B is just a copy of A ? Or does google know once the URL changes that the content belongs to the new site B ? What else can i do ? Should i just totally kill SITE A off ? I now have serach engine entries of A and B in the engines, actually i want A be gone and i am afraid of duplicate site penalty.
i guess to make things easy, google see's a new URL that is new or hardly established, moving traffic to your new site will help but you will need to start adding your new sites to se's, dirs and start building links.
well the problem is not moving traffic, both sites are extremely new. Site B is only a day older. My concern is duplicate content penalty since i have sites A and B in the SEs now...so..wont they compete ? I just dont want site B ranked low since google thinks the same content is already on A !
If you park the older domain on the newer domain and do the 301 redirect, in about 6 months the older domain will no longer be listed in the engines. At least it won't be in Google. If it isn't listed there is no reason to make the effort. I personally did this about 8 months ago. I can PM you the domain names so you can check the others if you want to verify this. I don't care to drop them here.
