www.learn-english-grammar.com is PR 5 and has 448 pages indexed by google (site: command) but a weight of 792. I've read a lot of the posts on this board about how API keys might be part of the problem? I don't ahve an API key so is that somehow hurting my weight?
No it isn't hurting your weight if you don't have a key. It just enables you to revalidate whenever you want. It won;t increase or decrease your weight at all. If that's your weight then that's it. It seems low but it isn't because most of your pages are supplemental results. Your 'real' pagecount is probably just 100 or so. See my FAQ here: http://co-op-faq.blogspot.com/2005/03/6-weight-weight-loss-issues.html For more info.
I'm not sure about the difference between real and supplemental. I know "Our users have posted a total of 461 articles"....
