Here at Support Lounge, we regularly experiment to determine the best methods of Search Engine Optimisation (SEO).
Feeder sites can be mini-sites that feed traffic to a main website based on certain keywords.
For example, because one of the things we do is fix computers in Wembley, we have just set up Wembley Computer Repair to help pick up on searches using that term. Should we keep the new site as a separate feeder page or should we re-direct the domain to this one.
We will experiment and determine which works best.
