It may be that spiders are having problems zooming through your site, and just keep trying.
Have you done any strange linking 'tricks' that might be causing trouble?
To get good listings, you need to be spider-friendly; and to get visitor numbers, you need those listings.
So think carefully before using robots.txt - use it to eliminate duplicate URLs and other unnecessary pages so often produced by databases - but be sure that 'content' pages don't get eliminated too.
I had a directory once with 37 categories, that produced a Google count of 700 and poor listings. Once I configured my robots.txt to ignore the bumph, I got a leaner, cleaner search result, and more visitors - because they stopped seeing nonsense pages in the serps. I suspect that poorly-structured dynamic sites do create unnecessary work for spiders, which eventually bites you in the butt.
I have also never done anything but pretty simple and straight forward HTML - no tricks at all. We have a nice directory structure, have been on line for over 11 years, and have already enjoyed great love by most search engines. It just seems that these things come through without mercy day after day...
