General opinion is that PageRank is no longer as important as it once was. Google now looks at many factors in determining how to order results for a search. But Google does continue to publish PageRank from time to time. For a benchmark, www.homeaway.com and www.vrbo.com have a PageRank (PR) of 6 (out of 10). If you search for a site and it has a PageRank of 0, then it is a new site that has started since Google last published a round of PageRanks - every six months or so. If a site has a PageRank of 1 or 2, it's not currently very popular.
PageRank is calculated at a point in time. So a site could well have increased in popularity since the last round was published. There are browser toolbars that will show PageRank for a site. The simplest approach that I've found to show PageRank is PRChecker.info.

If a free listiing site has a PageRank of less than 3 then you should probably decide to hold off and check again in 6 months.
