Last I checked my real friends, none of them was a laptop computer.
Facebook, twitter, and other social networking sites are a huge cluster of people willing to share things. But to put something on it, you have to really become a part of it.
Like the image, there are a lot of other blunders of trying to market things through facebook.
I am no expert on these, but here are a few things I know:
1. Do not create a regular page for a product, celebrity or group
Doing so makes you look like a fool. There are specific pages that you can create for these. Addendum: Do not change your page name to another product. That's creepy and dishonest.
2. Do not rely on Google ads
As much as the figures talk great about Google's adsense, very rarely do you find something interesting and click on a Google ad. This is essentially what went wrong with BJP's approach in entering the web. LK Advani on each and every page didn't help much either.
3. Understand the medium
Networking through Facebook and Twitter really needs a great understanding of how things work. How a 'Like' button or 'Share' button work on facebook. How to bring things to the spotlight on a home page. And about '@replies' and RTs and hash tags in twitter. It's tough work, but you can really reap benefits.
4. Do not be seasonal
People can smell an advertisement from as far as another galaxy. Doing it wrong will be like that 'friend' of yours who tries to make you part of a pyramid scheme. Don't be a politician. Keep in touch, don't vanish after announcing your agenda.
5. Make it interesting
You don't create a viral video. You create a video, and it goes viral; as in it spreads from person to person. Have activities on your pages. Send regular updates that makes a worthwhile addition. Shareability is the keyword.
6. Be funny
Funny has a way of implying honesty. All good communication has that straightforward tone. Take digs at yourself. Publish something that you found interesting (if it remotely related to your product, great). Make sure people come back to your page for more.
7. Encourage discussions
There are few things as ghastly as an empty Facebook wall. So fill it up. Do not moderate unless outrageously offensive, or spam.
These are all I can think of right now. I am sure there are a lot more. But doing a few of these right can definitely help your product not end up in a blog like this.
