Okay, Start from the Beginning: a bunch of nerds, practically 'underground' (ranging from army-bunkers to mothers' basements) & 'philosophizing' with the information they found-in books & -on the news etc. The Internet gave them a way to pass that information to other nerds & receive some in return. The Information Exchange got so tangled that some nerds thought it would be good to organize the information to make it easier to connect info-seekers with the information they needed. That's the long-&-short of the history of search-engines. Search-Engine Optimization (SEO) is basically 'openly indicating why people would need the information you distribute.' People get over-involved, thinking it's about 'how many people try to find the information you distribute'; but that's only an after-effect. The point is: you're not looking for 'what people want,' but rather for 'a way to a) get the information you have to more of the people who-are looking for it -need it and/or b) more of the information that they-&-you need.' How does that fit with how things are currently going?
