You have probably already seen the statistic that states Google accounts for two-thirds of the world’s search queries. So where do the other one-third go? That would be the Yahoo Bing Network. Gregg Hamilton, at Search Engine Watch, jumped from this realization to investigating the pros and cons of the two dominant PPC platforms: AdWords and YBN.
The conclusion seems to be essentially what you’d assume, AdWords is superior. But, YBN has some merit. Though you’ll get less exposure, you’ll also get less competition. And with that, you’ll see a lower cost-per-click. You likely won’t get as much traffic and you’ll see a lower click-through-rate, but if you’re on a budget, YBN may be of interest to you.
