If you buy keyword specific domains, you're really buying the type in traffic.  I use the URL builder and redirect through that URL so you can see how much traffic your getting from the keyword domain.  There seems to be no rythme or reason to what keyword domains deliver traffic and what don't.  By tracking traffic with the Google URL builder you get a feel for what names are giving you traffic and which are not. ie. the plural, the singular, two words, three words, the possessive, etc.

No, no, no. ToysRUs made a perfectly logical decison that most any business would do and Google tanked them for it. ToysRUs wanted the url toys.com to direct to their site.  They're all about toys and they simply bought a url that described their business and told the url where to take people.  Google tanked them in the rankings because Toys.com came with link juice. Google assumed that Toys.com was doing this to manipulate the search engines but there is just, to my knowledge, ZERO evidence of this.  This is another case of Google caring more about the possible spam threat than the actual rankings for searchers.
The second option requires a bit more time and effort than a 301 redirect. You could do a mini overhaul of the site and turn it into a microsite for your main domain. This option is good for exact-match domains for your targeted keyword, and there are other reasons for going the microsite route that Rand's highlighted in his post about root domains, subdomains, subfolders and microsites. This strategy also works better if the old domain has decent rankings for the keywords you're targeting.
Expired domains with page rank, Alexa, TF, CF, Backlinks, DA, PA, RD, etc. are of much importance. It is because search engine values those expired domains because of their pre-built matrices. It can take you months to build that trust and then it will be of the value that you want. So, what if you can find expired domains with authority links like expired domains with CNN links, expired domains with Wikipedia links, expired domains with Huffington post links, etc. This kind of expired domains will provide you some great juice for your money website.
Something similar happend to me in an auction a couple of weeks ago, I won the item, I paid for it, got an email with receipt and all, and then the next day they took it away from me and got the refund.. I know it sucks…… Some auction sites take a lot of time to upgrade their auctions, and this complicate things to, u can win an item in sedo, and still be listed in go daddy or vicceversa, sometimes it takes them days, I once called go daddy and told them, “hey! That domain in auction is mine” , “oh, sorry we haven’t upgraded”..
For example, placing your backorder at NameJet will reveal your interest to other potential buyers so if no other backorders are present you should wait until the last possible moment before the deadline to place your backorder — because if you’re the only backorder, you’ll get it for the minimum $39 bid on expiring names and it won’t go to auction.

Once you get to this point you know there have been DMAS listed. They have a number of domains linking to them and according to the way back machine which is WBY, you can see their site age. So, if you want to go with an older site you can see right here whether or not this is a site that you might be interested in, but before pulling the trigger you do want to check two things.
Your course of action really depends on how much work and effort you can put into the expired domain. If you're barely able to maintain and optimize your current site, you probably want to just 301 redirect the old site (note: see my amended comment above about the link value not likely to be passed). If, however, you're more creative and have some time on your hands, you can try your hand at crafting a microsite. If you really know your stuff and are experienced at making money off various websites, you'd probably do well with the third option.
Finally, you want to head over to domaintools.com. Then put the domain into here. What this will do is it’ll show you the history of the domain, because a lot of times these domains have been dropped like four or five times and a lot of people in SEO feel this way. I’m not sure about it. If a domain has been dropped several times, then Google does actually devalue the links pointing to that domain. So, as you can see I just changed registrars a few times and it hasn’t been dropped or else it’ll say one drops or two drops.
Hi, I purchased a .org domain in a Godaddy auction, actually the closeout auction so it had been renewable and then available as a closeout after 36 days. I purchased the closeout domain because I was thinking of using it as a catchy anagram. I instead offered it to the Trademarked company to purchase for a nice sum of money, and now they are threatening to file legal action against me for “Domain Squatting” saying that I purchased it in bad faith. etc… The way I see it, is it was available for them to renew for 26 days, and if it was not owned by them they had a window of 10 days to purchase the name before I did in the regular auction. What’s your thoughts on this?
The dropdate for the following TLDs is not verified. Domains might drop earlier or later: .eu .cat .travel .ae .af .as .at .aw .be .bg .bi .bj .bo .bw .cl .co .cx .cz .dk .dm .es .fi .fo .fr .gd .gg .gi .hk .hr .hu .ie .io .iq .ir .je .jp .ki .kz .lt .lu .lv .md .mg .mx .nl .nc .nf .no .nz .pe .pf .pl .pt .ru .sg .si .sm .sn .so .st .su .sx .to .uk .uz .za .berlin .cloud
