Back in April, Google modified its search algorithm to favor mobile-friendly websites. Web developers and SEO experts dubbed the changed "Mobilegeddon," and it turns out they were right to be concerned.
A new report from Adobe Systems found that non-mobile-friendly sites have experienced a 12 percent decrease in traffic since the change. Those non-mobile-friendly sites responded by buying more paid search ads on Google, which increased the cost-per-click price by 16 percent, which was very good for Google but bad for small websites.
"Mobilegeddon fears have come true," said Tamara Gaffney, an Adobe analyst. She added, "This is creating a digital divide where larger companies are more capable of keeping up."
