We estimate below how many Impressions to expect per month. We base estimates on historical data so they cannot precisely predict the future. To increase the time-relevance of estimates we limit them to the last 30 days. (Estimates are actually made over the last 720 hours, which means estimates can vary throughout the day, not just from one day to the next.)
Yellow Page Categories cannot be exclusively purchased for a Campaign. Currently, all categories are available to all customers (as long as the category is relevant to your service or products offerings). When more than one customer uses the same category for a Campaign, all customer Ads triggered by that category are made available to be served as Impressions. The Position in which each Ad is shown depends on the past performance of the Ad. When more than 10 customers use the same category in a Campaign, the 10 Ads with higher Click-thru Rates tend to be shown more often and in the top Positions, which means the estimates below will tend to be an upper bound. (All Ads in a Campaign are rotated into the cycle based on their Click-thru rate.)
Historical data is on this page. It lists the 200 most popular Yellow Page Categories. The most popular category is Accountants-Certified Public, for which we displayed 367 Yellow Page Category Pages in the last 30 days. The category name Accountants-Certified Public is followed by a "(1-367)". The first number is the ranking, 1 to 200, and the second is the number of times we displayed Accountants-Certified Public Yellow Page Category Pages in the last 30 days (Page Impressions). If your Ad is shown every time its Yellow Page Category Page is this would be the number of Impressions for your Ad. If your Ad category is one of the top 200 you can use this page to estimate Ad Impressions. For all categories in the top 200 an upper bound to your monthly Impression cost is the sum of the $0.15 x that categories' Page Impressions for each category you have an Ad under.
If your Ad category is not one of the top 200, you can use the last of the top 200 categories, Technical Writing, with 27 impressions in the last 30 days, to estimate the upper bound of page impressions for your category (because all categories not in the top 200 will have fewer Impressions than 27). For the 3395 categories not in the top 200 an upper bound to your monthly Impression cost is about $4 for each category you have an Ad under. If you need a more accurate estimate, the bottom of each Yellow Page Category Page displays the number of Yellow Page Category Page Impressions in the last 30 days for that category.
