LotusJump user Greg Witt recently asked a great question about optimizing his Swiss Alps tours website:
“As I’ve been doing my Lotusjump SEO, I’ve noticed Google’s SearchWiki that allows me to customize search results and make my SearchWiki notes available to other users.
Is there a way to use this feature as an SEO tool? Could I conceivably boost my site’s ranking by my responses?”
For those that aren’t familiar with Google’s SearchWiki, here’s a summary of the feature from the NY Times,

[Google] is introducing a new feature called SearchWiki that will allow people to modify and save their results for specific Google searches. They can move the sites that appear in rankings up or down, take them out altogether, leave notes next to specific sites and suggest new sites that are not already in the results (or are buried too far down in the results to see). Users must be logged in to Google to use SearchWiki and can revisit their annotations when they perform the same search later.
So back to Greg’s question…can you leverage SearchWiki to boost rankings? Marissa Mayer, Google’s vice president of search product and user experience said, “At this time we aren’t using SearchWiki to influence ranking but it is easy to see how that could happen in the future.”
The fact that she even hinted at the possibility of SearchWiki influencing ranking leaves me with no doubt that it someday will. If you think about it, Google is aggregating some really valuable data with SearchWiki–actual human opinion. If their goal is to return the most relevant results for a given search term, why wouldn’t they take the average Google user’s opinion into consideration? This is the “human touch” that the mathmatic algorithm has always lacked. So I have no doubt this data will make it into the algorithm at some point–how soon, and to what degree, only Google knows.
So what now? I wouldn’t go overboard, but I’d give my honest opinion of search results in my niche, and encourage friends and clients to do so also. Be responsible and consider Karma.
But if this data someday becomes a factor, it will be nice to know that you have contributed your 2 cents.
