Google's grip on the Internet search market loosened in December, as the search engine saw its largest drop since 2009.
That loss was Yahoo's gain, as the Marissa Mayer-helmed company added almost 2% from November to December to bring its market share back into double digits.
[seealso slug=http://sale-online.click/2014/06/04/facts-about-google/%5D%3C/p%3E%3Cp%3EGoogle's lead remains overwhelming, with just more than three-quarters of search, according to SatCounter Global Stats. Microsoft's Bing gained some momentum to take 12.5% of the market. Yahoo now has 10.4%. All other search engines combined to take 1.9%.
The increase comes after Firefox switched its default search from Google to Yahoo. Mayer, Yahoo's CEO, has reportedly targeted default search positions as a way of gaining ground in search.
Increases in search share have translated into revenue growth for Yahoo, which has been starved for fresh income due to declines in the prices of online display ads. Yahoo now brings in more money from search than from banner ads.
Those increases have come despite Yahoo's deal to power its search with Microsoft's Bing technology, which also means the company shares the revenues from search advertising.
Google, meanwhile, is doing just fine with its search revenue, although growth has slowed. It has been able to maintain its overall growth by expanding into other businesses, such as media with Google Play.
