Aaron Wall’s interview with Matt Cutts has Matt talking about SEO apart from host of other things. Here is a brief excerpt from the Interview:
Is all SEO spam?
Absolutely not–I need to do a post about this on my blog sometime. Lots and lots of search engine optimization is white-hat and not spam at all. Things like making a site more crawlable, tweaking the words on a site based on what users type in or what you see in your server logs, and gathering links by coming up with creative ideas or services that make people link to you naturally. To me (and Google), spam is search engine optimization that is outside our quality guidelines–things like hidden text, hidden links, doorway pages filled with gibberish words that do a sneaky JavaScript redirect, and so on.
