When you search for ALife on google you'll be getting back everything on ALife. This includes professional research associations, academic institutions, etc. Obviously Darwinbots should be behind that.
Also, like I said before, we don't really say the word 'ALife' very much in the forums, etc. We're really just a small subset of what would be included under the title ALife.
If we really want to get hte message out we form relationships with researchers in the field, and have them talk about it and try it out. As we get professional support, we become more relevant, and our google hits will rise.
