Since high quality expired domains are in low supply, the huge numbers of marketers competing for those drop domains tend to drive prices up. Also, if you use an exchange, you’re basically lucky to get whatever you can afford. In other words, niche specificity isn't guaranteed. This is going to be a problem because as Google continues to evolve, it is cracking down on domain niche relevance. In other words, its software is fast evolving to the point that it can tell what the niche of a particular domain is. If your private blog network is a patchwork of expired domains that involve many different and dissimilar niches, then you might be in trouble. You are at great risk of being penalized by Google.

Answer: Registrars are not set-up to negotiate the selling price of expiring domain names. Their technical support team likely won’t even know what you’re referring to, let alone who to refer your inquiry to. It’s likely your offer won’t even be worth their time to handle. Unless you know the founder, president or chief operating officer of the registrar, you won’t even be able to have a dialogue about it. In addition, depending on how they interpret the ICANN registrar rules, it may not even be possible.
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.
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.
Also, I currently have two other domains that are registered with Squarespace, and I have their annual payments set up automatically so I never have to manually pay (and so nobody else gets that window of opportunity to take the domain away from me). Would it be possible that the owner of this domain might just have a similar system in place and that I might be wasting my time?
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.
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.
1. Some domain names don’t go to auction and are instead held by the registrar in their own portfolios (you called this “warehousing” by the registrar). This is probably less than 0.001% of the domain names….actually, probably even less. I suspect it would only be premium domain names with massive exact match local search quantities. Not surprisingly, I cannot find any information from registrars about their procedure, quantities of domains their keep, or ICANN’s rules (if any) about this.
Okay. So, let's move on to our next tab crawl from search query, something look at the settings. So if you want to limit the amount of results that you cruel per search query, you can tick that and specify, so if you only want to crawl the top three or ten results from each search query, you can enter that there. He'll just go to the end of the search. Next setting, results on Google skip the domain if it's in the majestic million, so the majestic million is just something from majestic, it's a free resource that majestic SEO makes available that shows the most popular hundred domains.
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:
