LeadsLeap & Wikipedia
Even though that’s my affiliate id.. it’s still a free site :)
You don’t need to buy into their pro version, the main reason you’d want to sign up is because they send great free marketing tips, and have heaps of free bonuses to download where half these ideas came from.. :)
If Wikipedia.com links to your site, your pagerank goes up.
There’s gotta be some ideas here for getting your link on Wiki.. you know.. ethically.. if not your main site, maybe to one of your social networking sites or your blogs, ie: Maybe you’ve favourited/have a playlist of some relevant videos on YouTube etc..
I haven’t done the wiki search myself yet, but didn’t want to leave it out, since it’s a great idea!
