Hi Kulwant, these are great tips as usual. I particularly like the way to tell us to check the google pagerank in case the domain has been banned – that could lower the usefulness of the domain quite a bit. One thing though, don’t you think that buying domains is sometimes immoral? Like sometimes you accidentally buy a domain of somebody elses website who forgot to renew.
Most popular auctions with expiring domains are at godaddy, namejet, snapnames. Search for expired domains name its very easy if you have domains list. With a bit luck, you can drop good one with PR5 cheaper like $200, just need to know which domain have not fake pr. List of domains are not free, but updated dailly with aprox. 50.000 new expiring domain names.
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
If you buy a domain from a 3rd party, the backlinks are valuable.  I always wait a few months before redirecting, so just set up a quick minisite until two page rank updates have passed and then go ahead and 301 redirect.  However, it seems that you'll get the link juice from the back links, the anchor text is ignored by Google.   Buying a domain at Godaddy TDName expired auctions, seem to not count as a dropped domain if you immediately set up a mini-site.
Searching for a suitable domain name for your website can be quite trying. The reason for this is that the names that you want to get have already been assigned and are not available. As an SEO you know the importance of getting a domain name that describes your business as closely as possible. For example, if you are running a car rental service, you will look for a domain name that has the words ‘car’ and ‘rental’ in it. So if you can’t find a suitable name, you could use the expired domains tool which might show you domain names that would meet your requirements.
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.
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've seen some people comment about losing the link value of domains that have expired and picked up, but what about non-expired domains?  Let's say a competitor is going out of business and they still have a year or two left, and we buy their domain and site.  Is there a risk changing registrant info and registrars, even if I keep their site up and mostly the same as before?  I was under the impression that I'd want to keep it under their name so as not to hit the uber-reset button on the domain's inbound link value.
Of course, this does not happen equally across the board. Some site owners are lazy and barely put in any effort. As you can probably tell, the four situations I outlined above probably will not occur for website owners who are lazy. Now, for website owners who put in the work and the time for their online properties, you can bet that they would get to benefit from the four situations outlined above.
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:
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.
