Some idee why I get no weight http://www.seo-contests.com/cgi-local/google.cgi?search=site:www.2pl.co.uk
i don't know the exact process of that but.. i think weight also correspond on the number of pages and the relevancy of it.
All your results are supplemental. Check around this forum and in the google one, it's a documented issue that I'm having as well, although I do at least have a few hundred in weight.
