I have a old domain A, penalized by google on 2013 June, then i 301 to a new domain B, after several month, also dropped, then 301 to another C, C ranking about 270 keywords for 1-2 month, then dropped to 150 keywords. so i delete it on google again, forbidden google robots, move to a new website, not use 301, now has been 1 month, only 3 small keywords appeared. Domain A--->B---->C ---->D 301 301 no 301 I let google no index all in google webmaster. Now A, B, C all forbidden google, no indexed in google A, B, C all purchased several differece link building services on here, total spent more than thousands of dollars. I have several questions 1. Now A has 1 keywords rank on 3 on bing, had no indexed in google for more than 1 year, if i let google index it again, what will happen? 2. Domain C, when i delete it from google on April 9th, it still has 150 keywords show on semrush, main keywords position is on 2-5th page, if let google re-index it, what will happen?
