Site is a month old with a couple hundred links. Hoovers around the 9-10 spot in google for it's keyword which is also it's domain name. Gets about 70 hits a day. Has a good wiki link. What other explanations are there for this?
i am not sure, but one of the reasons could be that you may have session ids being appended to your urls because thats a lot of activity for a few hundred pages site.
i have a theory on this based on where your links come from. i have a site which gets hammered from googlebot and i realised that this was when most of the quick backlinks i had created through commenting on blogs then linking to the comments from other blogs etc etc. create a big kinda network of blog comments. i think google gives a lot of weight to blogs and the like at the moment and this ends up with the bots crawling blog links a lot which ends up wth more crawls of your site. did you use comments to create many of the links?
Well, my situation supports these facts. I got one of the services here, my article with a link back to my site on a network of 200 blogs... interesting... also, the site has a phpbb forum on it
thats why msybe it has something to do with sessions. I recomend seo mod for phpbb to optimize your forum.
