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.

The database also gives us the chance to analyse Whois, IP, NS, MX records and website content of every domain and to offer unique investigation and brand monitoring services for which websites like Whois.Domaintools.com charge a lot of money. With the tools we have developed we can offer Reverse IP, Whois investigation and B2B research in bulk at a world class quality/price ratio.

Domain names expire when someone decides to stop renewing it. They may not be available to register immediately. We update the search index every night, so some names may already be renewed or re-registered. Some may become available in a few days. Some registrars, like GoDaddy, will let you buy a name that one of their own customers expire immediately. When you find a name you like, just click on it to try backordering the name!
The great thing about this is that it’s kind of like a metasearch engine for all the places that you can find expired domains around the web. First, let’s look at deleted domains. Okay? To do that, you go click on the deleted domains button here and then click on any top level domain that you want to get. I prefer .com because it’s obviously the most common top level domain.

DomCop has a great offer that all of you buying expired domains should consider. For the price of a couple domain names, you can use DomCop for a month, snag some excellent domain names, which would otherwise cost you thousands of dollars. If you're considering expired domain software and don't have the knowledge to program your own crawler, I'd lean towards DomCop.
As mentioned earlier, finding such expired domains can prove to be a daunting task especially if you don’t have a tool to make that process a walk in the park for you. Instead of spending your time searching for tools that you are not even sure will help you find expired domain names with lots of traffic and backlinks, how about you try a game-changing tool integrated into Webfire 3.0 software called Expired Domain Finder and make your expired domain search a lot easier?
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.
The whitelist filter for wanted characters is now split into three filters. The old whitelist is now named whitelist (only). When used, the domain has to consist only of the defined characters or numbers. No other characters are allowed. The new whitelist (any) filter finds domains that have at least one of the defined characters or numbers. The new whitelist (all) filter finds domains that have all defined characters or numbers at least once.
