Hi, My 400 pages site A is at www.example.com. This site is now useless since it is related to a past event: few people search its keywords in Google nowadays.
I am creating site B, about a similar event, at subdomain.example.com. 15 pages of site B are copies of site A pages.
In order to avoid duplicate content issues, and try to transfer part of the popularity of site A to site B, I plan to 301 rdirect the 15 pages from site A to their copies on site B.
I think it might be a bad idea to implement all 15 301 redirects in one shot. I fear it might trigger a penalty on site B (new site on new sub-domain).
- How do you think I should proceed? - Should I 301 the 15 pages one after the other, and how long should I wait between 2 301s? - Until one page from site A is 301 redirected to its identical page on site B, should I put the page online on site B (creating a temporary duplicate content)?
Some people change domain names and their site can have thousands of pages. All thousands 301 to the new domain and they have no problems in ranking. You will PR disappear but that is not really relevant if you are looking at ranking and conversions.
