The amount of links within each directory differs quite a lot. There are directories with contain
only a few links and there are others with thousands or in some cases millions of listed Websites.
It is the same thing with the quality of links. In some directories every link is listed to gain
content or to get a reward for setting the link. Other directories have very strict editorial
rules and allow only links which they consider of high quality.
All directories within each list are sorted by the
Pagerank
which was available when the directory was visited. Minimum trade-off lists the minimum return service that is requested by the directory to accept a link proposal. In some cases the author might be mistaken and above that meanwhile some of the data might
have changed.
