No matter how good the SEO ... someone will always tell your client it's horrible. And "prove it" with an SEO report card. And then no matter how much good you did, your client will always have that thought in the back of their mind that maybe it could be better.

Little do they realize it could be a lot worse.

Here's some of the crazy I see far too often:

- SEO guys that run paid traffic through their client's affiliate programs, to generate commission on top of the regular fees they charge.

- SEO guys that offer a short-term contract initially to reel clients in, use the initial fees to actually purchase products from said client's website, and then use perceived increase in performance and revenue to get a long-term contract paid up front, and then disappear.

- SEO guys that charge for plagiarized blog content.

- SEO guys that convince clients to pay thousands of dollars to add "meta keywords" tags.

- SEO guys that rewrite click farm traffic to make it look organic.

- SEO guys that install "backdoors" on their client's hosting accounts to continue monetizing the website via backlinks long after they've been "fired".

- SEO guys that hold businesses hostage with duplicate websites (similar to this story).

- SEO guys with english-as-a-second-language, that charge for "Content Marketing"

- SEO guys that charge their clients thousands of dollars to setup and maintain Facebook, Twitter, a Blog, Instagram, Pinterest, Google+, Tumblr, then do nothing on them for years and hold their clients hostage for additional fees when said clients realize they're not getting their money's worth and want account access.

- SEO guys that register the domain name and hosting on the "clients behalf"
