Social networking and social book marking sites allow people with similar interests to get together in groups and discuss the subjects and products they are interested in.

This can be of use if you are marketing your products and services on-line as you can also join these groups.

You can find out what people are talking about and what they are looking for when it comes to your products. This will help you with your keyword research and with producing tools or information to attract new visitors to your site.

When using these sites, you must be careful not to appear ‘spammy’ and just out to promote your site.

You should offer help and advice to members of the group and become recognised as the expert in your field. This will result in not only more visitors but also visitors who trust you and are ready to buy from you.
