How to Determine Appropriate Page Counts

Keep in mind that if more than 30 percent of the pages lose money, you might want to reduce the page count by eight pages. It's a matter of proper balance. Be careful that you don't have too many under-performing items as a percentage of the total number of unique products in the catalog.

Pay particular attention to products that are being carried over to appear in the next book. Knowing when to drop a particular item is crucial. Products that are repeated in a catalog will tend to have a revenue drop-off of about 20 percent each time. If the decrease is more, replace the items.
