Measuring Google Mindshare

Measure the Google mindshare of a particular person within a query domain.

Based on an idea by author Steven Johnson (http://www.stevenberlinjohnson.com), this tip determines the Google mindshare of a person within a particular set of Google queried keywords. What's Willy Wonka's Google mindshare of "Willy"? What percentage of "weatherman" does Al Roker hold? Who has the greater "The Beatles" Google mindshare, Ringo Starr or Paul McCartney? More importantly, what Google mindshare of your industry does your company own?

Google mindshare is calculated as follows: determine the size of the result set for a keyword or phrase. Determine the result set size for that query along with a particular person. Divide the second by the first and multiply by 100, yielding percent Google mindshare. For example: A query for Willy yields about 1,590,000 results. "Willy Wonka" +Willy finds 66,700. We can conclude - however unscientifically - that Willy Wonka holds roughly a 4% (66,700 / 1,590,000 x 100) Google mindshare of Willy.

Sure it's a little silly, but there's probably a grain of truth in it somewhere.

Running the Tip

Visit the CGI script in your browser. Enter a query and a person. The name doesn't necessarily have to be a person's full name. It can be a company, location, just about any proper noun, or anything, actually. Click the "Calculate" button and enjoy. Figure 6-20 shows the Willy Wonka example.

Fun Tip Uses

You can't do too many practical things with this tip, but you can have a lot of fun with it. Playing "unlikely percentages" is fun; see if you can find a name/word combo that gets a higher percentage than other percentages you would consider more likely. Here are the answers to the questions posted at the beginning of this tip, and more:

• Willy Wonka has a 4.82% Google mindshare of "Willy."
• Al Roker has a 1.45% Google mindshare of "weatherman."
• Ringo Starr has a 1.69% Google mindshare of "The Beatles."
• Paul McCartney has a 3.71% Google mindshare of "The Beatles."
• Red Hat has a 3.63% Google mindshare of "Linux."
• Microsoft has a 4.37% Google mindshare of "Linux."
