I already use AdWords or other Search Engine Advertising. Why should I still list my book with Substance Books?
AdWords, Featured listing on engines is considered Search Engine Advertising. Your results/ads will appear in a different section of the results page, depending on the engine. Some browsers don’t bother looking at paid advertising. Your payments will also only cover the engine or engine cluster in question. To cover all core engines you will need to do the same on all. Substance Books however uses Organic Search Engine Optimization. techniques that will show results on all major engines within the “real” engine results based on online reputation and popularity.
