More Pages, Higher Sales

If you add pages that sell product to a consumer catalog, you'll get higher response rates and sales in rough proportion to the number of pages added.

"What makes this rule work?"

This rule works because adding pages usually means adding more products.

For example, say you have a 16-page catalog with a product density of five products per page. Excluding the front cover, you're offering 75 products. Now if you add an extra four--page signature (your catalog grows to 20 pages), and if those extra pages have the same product density as the rest of your catalog, then you'll be offering 20 additional products— a 27 percent increase.
