Best ways to do social media are Facebook, twitter , squidoo, my space, etc. You tube and video promotions Forum postings on traffic websites.(needs to be expert in this as it requires great writing and knowledge skills)
At first make friends as many as possible and start promoting your business sites,blogs and share anything you like to be popular. Make the best use of media sites so that you can get profit in your business.
You can make a cover letter with your site and post on your wall(facebook, twitter, digg and any others). I think these are the best tactics for making promotion any site.
If you are a brand owner - create your brand page at Facebook, Twitter and G+. After you gain audience to that page, you can use it as the best advertising tool ever!
Post updates of your site through your account walls. Facebook and Twitter are such good example of social media that could give you traffic. You can also create page on Facebook. Invite more friends and invite them to like your page.
The best tactics in social networking site is to become active on the sites where you are going to join like facebook, twitter and other and them make a lot of friends..
Hmm well other than ads, the best tactic is to really create a big trend for your product that will get online users really interested on your product. It will not only give you traffic but also good conversions if you are able to make that tactic very effective - though it is quite hard to do that since a lot of ideas are already coming out of the box.
Traffic is what you should target on. To get the most traffic, make your account the highest exposure by making lots of friends with your accounts. When you create posts or share something, make sure they have good keywords in the title, tags, and content for SEO purpose. Many social media sites has high PR, so it is possible for your post to appear in the top of search engine, if the keywords are of low competition.
Well it depends on your use..If you are using social networking sites for fun than make friends and enjoy but if you are using it for promotion or other purpose than start sharing your links there in Facebook, twitter , squidoo, my space, etc...
