SEO is not as easy as it used to be. The market is very saturated now, content is now incredibly easy to generate and publish. Everyone and his dog (or gran!) can make a wordpress website. The main ranking factor for Google is still backlinks and will be for the foreseeable future. Your content might be better than your competitors but if they have more links they'll simply always outrank you and receive more traffic. Fair or not, its a fact. This method can see you get the strong backlink profile you need to rank #1. Please note a PBN is considered black hat so please diversify your backlink profile and do your research first.
Surely if you purchase a domain (domain1.com) and redirect it to your existing domain (domain2.com) you expect to loose all ranking for domain1.com. If 301's are used then the objective is simply to pass on authority, not dominate the search results with 2 domains. If you want to keep domain2.com in the index then you would take Rebecca's option 2 or 3.
I don't necessarily agree with some that dropped domains don't have value for SEO purposes but either way one thing you can do is to check out our tool for finding auction domain names (the tool has a database of domains available buy from GoDaddy and SEDO and also give additional SEO criteria to look up for the domains like backlinks, Compete data, CPC, Google stats, Alexa stats, etc. and there is also an option to schedule auction domain alerts so that you can be notified via email if a domain name meeting criteria you specify gets put up for sale) or you could use our tool fo domains dropping soon that shows all domains dropping in the next 5 days that way you can be ready to snap them up right away.
