SparkToro recently published an article that corroborates our belief that if you're using any other search network for your marketing, you are just wasting your money.
That data was provided by a click stream data provider, JumpShot and backed by StatCounter's numbers as well.
The data shows that Google far exceeds any other search network in market shares with a combined total of over 90% of shares (between Google Search, Google Images, and Youtube).
Trailing the search giant is Yahoo with 1.57% and Bing with 1.48% of market shares.
You can see the extreme disparity between the search network which can directly be attributed to customer reach.
Unless you are strictly trying to reach Nana bumbling around on Yahoo in her living room, then you are far better off reserving your marketing budgets for Google and cutting out the wasted ad spend on Yahoo and Bing.
The moral of the story here is to be where your shoppers are and that most certainly is on Google search networks.
