SEO things that make you say "what!?"

[White.net]

Hi everyone,

I'm a recent(ish) beginner to SEO, and while I feel I've got a good grounding in the industry now, there are still certain aspects that make me say "what!?". I'm looking to write a blog post on this and would love to know what parts of SEO still confuse you or make you say "what!?", and explain them from a semi-beginners point of view.

Any comments appreciated!

Thanks!

This made me say "What!" With some other words following.

Not specifically SEO, but when comments nowadays suggest link farming, also makes me go "What".

What makes you say 'what', White?
