Bad reasons for advertising on your site

Few things annoy me more than sales reps telling me I should advertise on their site because my colleagues in other offices do.

Even fewer things annoy me more than telling me I should because my competitors do.

I’m trying to beat those guys, not join them.

If you think “because the other guys are,” is a good reason, I’m not interested. It might be good information to know, but no decision should hinge on that.

Suggesting that it might greatly affect my planning is insulting, so don’t do it.

And it sort of suggests that you don't have any better reasons.
