As I study SEO and read the experts’ advice (check out Search Engine Land) I am circling back to where I would have started. Just write thoughtful, authentic, and consistent articles. Pay attention to your community and link to informative content that adds context to your story.
There are articles on what not to do – essentially don’t trick the search engine with content not meant for your readers. There are articles on what to do – selecting key phrases, and paying for them. Overall the best approach seems to be to create fresh, pertinent, content that draws a reader enough to come back and share.
This Periodic Table of SEO gives a great summary of the advanced elements of SEO – but I keep coming to the conclusion that good quality frequent writing is the way to improve rank.
