An Untapped SEO Opportunity: Image Link Love From Wikipedia suggests that web marketers should license their images under CC Attribution-ShareAlike and contribute them to Wikimedia Commons for use on Wikipedia sites.

I like this advice for the obvious reason (encouraging CC licensing, especially under a liberal CC license), but the remarkable thing is that following this “Search Engine Optimization” advice contributes to the greater good. This is largely a testament to the robustness of the Wikipedia community. As I said regarding similar but broader advice earlier this year in Creative Commons for Newspapers, Scientists, Film students and Wikipedia SEOers(!?):

Apart from the CC recommendation, this last article really points to the benefits of the Wikipedia community. Normally ’search engine optimization’ is associated with people basically attempting to scam the search engines’ anti-spam defenses, but most of the article’s tips on participating in Wikipedia are for the good — it’s hard to get any value out of Wikipedia without adding value for others, i.e., it’s hard to scam the Wikipedia community.
