When searching from keyword DHG will take your list of keywords and search each one, the pages will then be crawled to find unique domains to check availability of. The process is relatively simple but very time consuming when done manually or semi automated as was necessary in the past. Luckily now the job can be set and left to work while you do something else.
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.
It is very possible that the owner has a recurring payment in place, or that the owner renews after it expires. Because GoDaddy gives a redemption period like all registrar, many domain name investors will actually allow their domains to go through auction to see what the “market value” is of a domain name and THEN renew it. It sucks if you’re the buyer thinking you won the auction. It happens often, unfortunately.
If you buy a dropped domain from Snap or Namejet, the backlinks seem to be worthless for SEO. They are valuable for traffic if it's targeted to your site. Go ahead and 301 redirect into your site because it's the traffic from the back links that is worth something. I use the Google URL builder to redirect these names so you can see the domain the traffic is coming from.
Your best chance of getting it is contacting the current registrant and negotiating to buy it. After that, your best chance is buying it in auction or finding it listed with a “buy it now” price at a marketplace. Your other option is to find a broker who can negotiate on your behalf (if the domain name sells for a few thousand or higher…brokers likely won’t have the time or inclination to negotiate smaller deals).
Once a domain expires, the registrar will allow around 30 days for the original owner to renew it. This period depends on the registrar and can range from 2 weeks to a whole year. Once this period is over, the domain enters the "Pending Delete" status, during which it cannot be renewed, purchased or modified in any way. Once the Pending delete status is over, the domain is dropped back into the available pool, and can now be purchased by anyone.
I am interested in a domain name that is set to expire in April 2016. The domain is registered with Domain.com, so I have placed a backorder on Snapnames.com (thanks for confirming I at least did that part right). I also placed backorders with NameJet.com and Pool.com, based on previous advice I received. Now I’m wondering if that might be overkill since Snapnames is the designated auction house. Will I ultimately end up bidding against myself?
Regarding my statement above, “Any domain name that reaches expired status and is not renewed by the owner will be auctioned by an auction service.”–it did overstretch. I’ve modified it to be: “A domain name that reaches expired status and is not renewed by the owner will be listed at an auction service (see FAQ for exception to this rule).” Then I added a FAQ to clarify. Please check my thinking:
