Kathy Caprino's recent excellent blog (link below) on how to reach out to a stranger on LinkedIn highlighted one of the biggest mistakes I've seen people make on LinkedIn.
Here's how the scenario goes -
1. A stranger sends me an invitation to connect (always personalise your invitation, please).
2. I decide to connect with that person.
3. I immediately receive an email from that person via LinkedIn - it is an obvious 'copy and paste' sales blurb.
5. Any positive vibe I had gotten from that person's profile is destroyed.
6. I remove the connection.
LinkedIn is not for selling - it's for building great business relationships. Please, take your selling offline and get to know me first!
Don't pitch them just because they've accepted your LinkedIn invite, and absolutely don't automatically pitch every new connection (every time I see an email or LinkedIn messages that starts "Hello" without my name, I know it's an autoresponder that many others are receiving.) A LinkedIn invite acceptance is not an invitation for you to hawk your wares. (Truly, I'm completely floored at how many people today haven't learned the etiquette of networking.)
