Via SEOMOZ I see on Quora.com "What is the single best piece of SEO advice?"
My advice: Forget about SEO.
Okay seriously - I think SEO is just an industry buzzword for common sense. My SEO technique is anti-SEO or maybe deconstructive SEO. Meaning you will get your best SEO results by forgetting about SEO. Just do everything like a human would, and use common sense. Correctly name and label all files, folders, directories, etc. like a human - not a machine (i.e. words, not numbers). Write original content. Make list and references. Use great original photos and video. Blog, tweet, tumble and use Facebook. Answer questions. Comment in other places. But just keep working - and forget about SEO.
