Hello Fellows, As 301 Permanent Redirect will transfer all juice to new site. So in my opinion following method should work:- 1. Register new domain/site, populate with unique and original content. 2. Leave site idle for 2-3 months so that search engines can crawl it naturally. 3. Register any expired domain with clean backlinks profile in same niche 4. 301 Redirect domain to new one. 5. Witness ranking in 1-2 weeks. Let me know if this method can work. If Yes! Then why not everybody is using this as this appears to be simplest to rank site.
