Owned by Yahoo!, Flickr is a web site that offers photo sharing and other services on any level, amateur or professional.
Flickr can be a useful source of online marketing your small business. As with other social networking sites it's important to be responsible and avoid using hard-sell tactics in your photos, comments, discussions, etc.
Flickr has been used by many corporations to effectively market their products:
Flickr is very popular for promotion purposes amongst: artists, photographers, estate agents, universities, museums, models, and many more.
Flickr is often ignored by small businesses because they aren't good at creating high quality non-marketing images. What Flickr wants is high quality images because Flickr is a community where high quality imagery is admired and appreciated. To promote your business on Flickr you have to treat almost every event as an opportunity to create content you can upload to Flickr. Whether that be conferences, speeches, new products or simply a new coat of paint.
Finally, Flickr can be a good place to check out what others think of you. If they post photographs of that dodgy hotel room you know needs redecorating, then well, you know you need to get on with it!
