I noticed Google has 100 Pages of my site in it's cache, after 3yrs of being constantly being crawled i thought this number should of been much higher (Just on our forums we have over 3,000 pages).
Anyway i thought it was a weird number to get stuck on so checked out some competitors and saw they all had exactly 100 pages chached too.
This got me thinking on wether i should set up googles permissions so it can not enter the more 'off-topic' areas of my site and restrict it to the parts which are better keyworded and heavily competative as i noticed alot of what was listed was irrelevant to what i want listed and held no value.
I.E. I found lots of forum junk in the areas none related to 'music production' which is a very competative keyword i am trying to push hard and which for example in our 'music production tutorial' section are naturaly heavily used within our tutorials.
Hence the question:
Does google actualy cache more than 100 pages and just restricts the search to the last 100 pages crawled (or something similiar when searching pages from a specific site) and there is actualy alot more than 100 pages listed in google if searching for a specific term (hence i would not have to restrict it from accessing the more uninteresting and none important keyworded sections).
BTW we are not a commercial site, just a hobby site ran with volounteer staff for helping people get into music production with tutorials, help & advice... along with a couple of off-topic sections just to keep a community spirit going when the more informative sections are lacking in new original content to keep the place ticking over and people to keep returning to us.
Thanks for any help in advance upon this situation.
