I would like to create a simple web shop from the scratch, but I'm not sure if ext is a good platform for. We use extjs mostly for intranet, business applications. The main problem is that ajax based applications are not crawlable for search engines, like google for example. Google has some complicated rules(html snapshots and so on...), but there are also some other search engines, which don't follow google rules. So, what do you think, how you deal with this problem? Is there some good pattern, example how to make ext pages crawlable?
