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.
Some people might want to skip that because they think that they've already been crawled, which is a possibility and you can apply a manual exclusion to any results you think are going to be returned on Google for your search query. So things like YouTube, you don't want to crawl, then you can add them in there and it will ignore them if they returned in the search results. Okay, so that's yeah! That's pretty much the search setting query settings here. So your search terms go here. You can have as many as you like just enter them in their line separated.
This is not the case at GoDaddy Auctions, however. There, GoDaddy starts the auction before the domain names has fully expired and the registrant does have the ability to pay a one-time restoration fee to restore ownership. This is particularly frustrating to those bidding in the auction, as you may be the winning bidder and pay your winning bid price only to find out a few days later that it was restored. You then have to wait for a refund from GoDaddy.
To get the most from GoDaddy Auctions, you should first decide on the way you want to evaluate the domains. Domainers tend to look at the words in the domain name, while SEOs care about the backlink equity. If you are a domainer, you should look at Estibot, Domain Index or Valuate scores. If you are an SEO, you should look at the Ahrefs, Moz and Majestic metrics to gauge the value of the backlinks. Once you have figured this out, you should look at these numbers for every domain you find on GoDaddy Auctions. Do not be afraid of bidding on the Closeout auctions, as you can get good domains for cheap.
