This session looks at the principles of Search Engine Optimisation (SEO) to attract website visitors, and the tools and techniques for tuning website effectiveness. Using book marketing examples, it focuses on so-called organic search (natural search) and doesn't try to cover everything: rather it zeroes in on the most important things that website owners can do themselves with minimal technical knowledge. Search Engine Optimisation is part of the broader field of Search Engine Marketing (SEM). The related Part 2 presentation covers Paid Search using Google Adwords, YouTube and similar opportunities and briefly looks at measuring results using Google Analytics.
