Top IYPs & Business Directory Sites

Main chart of top Internet Yellow Pages (IYP) sites daily unique visitors, according to Google Trends.

I used this chart to illustrate an article about how Google has reduced traffic to yellow pages sites due to some usability changes they've made, defaulting more user search results to include a 10-pack of Google Maps business listings according to the searcher's IP address geolocation.

This chart includes Yellowpages.com, Superpages.com, Citysearch.com, and Whitepages.com.
