Social media marketing can generate sustainable and meaningful traffic for a website, an expert has suggested.

Industry commentator Jason Lee Miller, writing for online resource WebProNews, suggested that when content is picked up on through websites such as StumbleUpon – where users recommend articles to their peers – it helps develop a brand’s reputation.

Furthermore, he continued, where websites are obviously only submitting marketing copy, they will quickly be "tossed out" for abusing the trust of other users.

"In other words, StumbleUpon or Digg are not places to dump pitches and glitter. They are places to build a brand," Mr Miller explained.

Last year, Cameron Olthuis, the director of marketing and design for search engine optimization firm Advantage Consulting Services, commented in an article for Search Engine Land that such websites can help drive traffic to a website.

However, he noted that for content to be successful at improving visitor numbers, it must be useful and informative.
