I purchased OptiLink, why do I only have 4 search engines enabled?
First and foremost, OptiLink is a tool designed to explain top ranking so that you can do better. Because OptiLink uses the linking structure of the web, we really only need access to the 4 indexes of the web that are used by all the major search portals. The search engines enabled in the standard version of OptiLink provide the easiest and most realiable interfaces to these 4 indexes. OptiLink is constantly updated to keep abreast of changes in the search engines and the aliances between them so that you have access to link index that is available. The additional search engine interfaces not enabled in the standard version are for purposes other than rank analysis and linking optimization.
