Robin Good: If your site has suddenly disappeared from search engine result pages you may likely have overlooked one of these 17 typical mistakes, that can get your site de-indexed in matter of seconds.
Nothing new under the sun in this list, but always a good reminder to look at if you are new to web publishing or if you have been recently penalized and are wondering what you may have done wrong.
From the article intro by Eric Siu: "...unnatural link acquisition isn’t the only way to get banned by Google. There are actually quite a few more. If you are new to SEO, let this be a warning.
If you are a seasoned SEO, let this be a reminder—or a crib sheet you can forward to anyone who is suggesting you do WHATEVER it takes to rank them.
Here’s a list of absolute “don’ts” where ranking is concerned."
Good reminder for everyone. 7/10
