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.
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.
So, let's start off with the simple website list crawl. So settings for this is covered by the general crawl settings and these apply to all the other types of crawl as well, such as the Search crawl and the Endless cruel, so pretty simple really. Delay between each request to a website. One second, this is in seconds. Secondly, concurrent websites crawl how many websites you want to crawl at any one point in time and then how many threads will concurrently crawl per website. So that's ten, a crawl of ten websites at once, and each of those websites there's three different threads crawling. That's 30 concurrent connections you've got going.
If it contains any of those, then I am going to crawl it. Otherwise, I'm not going to because it's probably just something like an Amazon listing. Okay lets move on to the endless cruel. So this is the endless crawl. Basically, here you put your seed websites, one will do if it's a big website, because there's probably loads of domains on it. If it's a tiny, tiny a website, then you might want to stick a few more in so, as I was saying before, it will crawl on all the pages on these websites and then for each external domain that it finds on that website. It will check whether it's expired if it's not expired, it'll try and crawl it and then it will start the loop again, it'll try and take all the domains from there check that they are expired.
And then you hit on ‘search’ and ‘all auctions’ and this is going to go out to lots of different auction sites, in fact I’m just going to stop this search, and it’s going to go out to all of these domain auction sites, find a list of domains that are relevant to your keywords and then pull back all of the data that you need to make a good buying decision.
Everybody going to start using old domains should also know how to get them, I'm going to post soon article about it on seomoz as there are several ways starting from online rankings and lists up to dedicated seo tools that you can run on your computer and get precise and actual data on demand for any domains lists.

Page authority ranking criteria are similar to domain authority. It’s ranked on a scale of 1 to 100. Page Authority measures the predictive ranking of a web page. The page authority of a website can change depending on various metrics. Search engines examine the relevance and authority of a page based on its contents and external links. If a webpage has links to higher authority sites and has keywords in it, its authority ranking will increase.
The way this list is implemented means I can't update prices, nor removed sold domains automatically and sedo doesn't provide me with the tools I need to implement it properly. Unfortunately some users keep contacting me to update their domain prices or remove their domains and I can't keep doing that manually. So I've decided to disable the list for now.
