Ah! That is where I think I am stuck. I do not know. I do not think I can actually give something to users in that kind. I can give information on quite many things, and I think that is what I am doing with WiseTome.com. I have another project rolled up under my sleeve that I hope to create good content in terms of forums.
For example a nice flash game, a usefull freeware program, a good structured discussion forum etc.
I do use Google Sitemaps. They show if my websites have problems that prevent spiders from crawling my site properly. Another nifty part of the Sitemaps is that it gives the set of keywords that the spider bots associates my site with - I think this is similar to the ones that are picked up by the Adsense bot, and I can actaully see if what I want comes into that set or not.
Google sitemaps is also a good idea to use, I found it quite helpful for my website and helps ensure things are going ok for the crawlers and such.
