One of the avowed aims of the brilliant engineers at The Plex is to negate the efforts of "optimizers" who are trying to influence the natural selection of the G ALGO.

According to Matt Cutts there are changes almost daily in their efforts to achieve this, and we are delighted each time they progress in this direction, as some of our competitor's sites go backwards.

We have over 4,000 directories on our list whose link pages appear not to be recognised by Google. In other words, you could have 4,000 links, more than most site owners dream about, all of which are a complete waste of time. Obviously we no longer use these.
