I registered for backordering with GoDaddy last year, as i saw goddady was the registar of the domain i wanted. However when the deadline for renewal came, i got a message the expiration date had changed to expire… well, a year later, i.e. now in 4 days. How can the expiration date be postponed? Was that the registrant renewed? does that mean the domain never becomes available and never goes to auction?
If you really don’t want to spend anything at all for your domain, that’s okay too. There are lots of ways you can get a free domain name for your website How to Get a Free Domain Name for Your Website How to Get a Free Domain Name for Your Website Why pay for a domain name when you can get a free domain name with your website? Read More . In the end, a domain name is really only a small part of your site. Really, the success of a site depends largely upon what you decide to do with it.

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.
1) pending delete auctions.  These are domains that were not renewed and are going through a pretty complicated drop process.  You can backorder these names at the auction venues and then each attempts to "catch" the dropping domain.  If one is successful you win the domain at $59 if you're the only one to backorder the name.  If more than one person backordered the domain a 3 day private auction is held.  Once the domain goes through the drop process, the back links have pretty much zero SEO benifit to the new domain owner.

The third option is the one that's the most time consuming but also has its benefits. It's like having a successful restaurant and buying another restaurant and operating them simultaneously. They're not the exact same restaurant, but both are popular in their own right and make you money. The same goes for Option #3. You could update the content on the old domain and sell the same products that you're selling on your current site. If you can get both sites to rank alongside each other in the SERPs, you're increasing your conversion chances and sales potential.

Sometimes people purchase domains that they plan to build a website on or sell in the future, but it just doesn’t end up happening. If an individual decides that it is no longer worth the yearly investment of keeping the domain in their account, they may choose to let it expire. Or, someone might just forget to renew the domain before the expiration date. If this happens, it’s a great chance for other domain investors to score rare domain names that are pending delete. Spending time perusing the list of recently dropped domains can be a worthwhile way to find high quality domains.
I am a rather gray-hat affiliate marketer by trade, but I"m looking more into going into local SEO and blogging ventures that I feel will be most sustainable. I am having serious moral issues with using any of my link building strategies, but the one I'm struggling morally and long-term strategy-wise is the use of a manufactured link-juice-flowing-thick private blog network. I believe the majority of these will ultimately fall by the wayside in the future when their social value and content are proven to lack substance by machine reading and advanced social metrics. 
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.
But unless the domain name you want is undesirable to anyone else (e.g., it does not include real words or have a high search volume for the words), the odds are not in your favor. With over 210 million domain names registered and an active, worldwide domain name investing community, it is highly likely that someone else will also find interest in the domain name you are watching. As such, skip to Step 4.
Trust flow refers to the number of quality backlinks that a website has. If backlinks from websites that have a high domain and authority ranking point to your site; your website’s trust flow will increase. Trust flow is also measured on a scale of 1 to 100. If your website has a large number of backlinks, but they are not from trustworthy and reliable domains, your websites trust flow will be low. On the other hand, if you even have just a handful of backlinks to sites that search engines rank highly; your trust flow will increase.
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).
If the domain name is not with any auction house partner (I think that’s what you’re saying), then you can use a drop catch service anytime: https://www.domainsherpa.com/domain-name-backorder-services/ They do not make your order public information as NameJet and others do by sharing how many bids are placed on a domain name and thereby driving interest.

What about option #4 - Redirect your existing domain to the old domain? I bought an old domain that is 100% relevant to my current domain but currently has with very little content. It did have more content fours years ago. The old domain is 13 years old, pr=3, while my current is 7 months old pr=1 and a decent amount of content. The old domain I purchased was not expired though and I do not know if this makes a difference. What are the pros and cons of option #4? Am I correct to think that option #1 would result in no benefit from the old domain's age value and if so why is it not listed as a con, a MAJOR one. Its hard to believe that a 301 using option 1 would give my existing domain 13 years credit but I'll take it if it does.
