This is a great article and reminder of what you shouldn’t be doing these days, in SEO. At least once a month I get asked why I’m not doing at least one of these techniques. It seems that bad information is still being published – so be careful what you read online! My favorite outdated technique is the keyword stuffing/seo-targeted writing. Due the complexity of Google’s algorithm, you really don’t need to use your keyword a certain amount of times per page in order for it to be optimized. Just write naturally and your keyword density (if that really matters anymore) will be fine. You should focus more on the quality of your content and marketing anyway.
