Social Bookmarking and Social Networks
Commonly known as ‘Web 2.0’ promotion, social bookmarking and social networks form a new type of promotion that has rapidly gained ground.

Previously, it was mentioned that these represented a valuable source of backlinks, and that much is certainly true.

However, apart from the backlinks that come as part and parcel of marketing efforts involving these websites, there is also the additional possibility of receiving traffic through those backlinks. After all, if there is an interesting bookmark that draws the attention of the crowds of people who flock to social websites, then there will probably be a correspondingly high amount of visitors who want to know more.
Despite this, there are two things that one should be aware of regarding social bookmarking, and social networks:

1. Not every piece of content is going to do well in social bookmarking websites. For the most part, the content that does do well when social bookmarked is those that are deemed to be ‘fresh’, ‘hip’,  expertly informative, or even controversial.

2. Research has shown that traffic from social bookmarking websites tends to have a very high ‘bounce rate’. What this means is that very few visitors that come in through social bookmarks will actually end up staying around long enough to browse your website.

3. Some social bookmarking websites are very niche specific, so finding those in your niche could presumably not only increase the value of the backlinks obtained, but also allow you to do much better due to the relevancy and automatic targeting of traffic.

Being a relatively easy and painless way to gain backlinks, and also build up
yet another traffic stream, social bookmarking is certainly worthwhile.
