Generally speaking, I try to avoid using the ampersand (&) when writing the marketing copy at a website.

Or anywhere, for that matter.

It’s too informal for me and a casual approach to writing marketing copy has potentially negative consequences.

Anything that has potentially negative consequences online, no matter how small, I try to avoid. Therefore avoiding the use of the & qualifies as one of my Internet Marketing Best Practices.
