SEO experts are like used car salesmen

Jeremy Schoemaker from ShoeMoney does not really like SEO experts and believes they are like used car salesmen.

His points are:

1) They can always sell you something.
2) They can never guarantee results.
3) They can not be held accountable.
4) They have a answer for everything.
5) All the magic happens behind the curtains – they cant tell you
what they are actual doing because that would be getting to much into
the secret sauce.
6) Anyone can be a SEO.

Well, you’ve got to admit Jeremy is good at starting a debate: one week later Danny Sullivan from http://www.searchengineland.com/ decided to do an interview with him to defend the SEO experts.

But did we need to be defended ?
