Chitika published a new study that reveals that "three-word search queries drive the most traffic from search engines."
Chitika looked at a "sample of 41,103,403 impressions of search traffic coming into their network between June 13th and 19th." Here's the breakdown of organic search volume by query length: Three words: 10,710,579 impressions – 26%, Two words: 19%, Four word: 17%, One word: 14%. "Any query beyond five words will see dramatically lower traffic," revaled Chitika.
The highest ad click rates were for queries of 5, 6 and 4 words.
