What are the pros and cons of building a bunch of smaller sites that promote and point to a larger site? Sounds spammy, right? There's always a way to do something without tripping the search engine spam-o-meter. Writes one poster,
I don't think there's anything wrong with using Site A to promote Site B. It only becomes a problem when Site A is the ONLY thing you have promoting Site B. When push comes to shove, Site B has to be able to stand on its own, as part of the mainland. If it's just sitting in the middle of an artificial island, the engines are going to pretty much ignore it.
