Yellow Pages ads deliver results to advertisers. In 2007, there were over 2,290 local advertisers in a metered ad database study that tracked calls and proved the medium works.

• 60% of these advertisers saw increases in call volumes in the second year, with an average increase across all advertisers of 19%.
• Of the advertisers that saw an increase in year 2, the average increase was 49% (median of 23%).

Testing answers advertiser questions such as:

• Value of larger ads
• Value of new heading(s)
• Value of advertising in a directory not previously part of the schedule
• Value of neighborhood or suburban directories
