In July 2006, SEOMoz released their now famous page strength tool.  The idea was to come up with a better metric for evaluating websites than PageRank.  According to Seomoz, the page strength tool was “a better metric to quickly assess a site / page’s relative importance and visibility.”  The page strength tool did indeed do this and as a result was a success and became very popular.

Aviva Directory then used this tool to build a list of the strongest directories.  This list ranked general web directories using the page strength tool.  It has become a popular resource, allowing webmasters to find quickly quality directories that are worth submitting to.  It added an element of objectivity to the ranking of directories, which previously had been done either purely subjectively, or simply relying on foolbar Pagerank.

However, the page strength tool had a number of limitations and controversies surrounding it.  To deal with some of these issues, today SEOMoz has released a new tool to evauate websites, the Trifecta.

We have now had a chance to run this test on most of the directories listed on our strongest directory list.  Here are the results, sorted by score (price in brackets):
