Since their innovation in the late 1990s, CSEs have been revolving in quantity, quality and specialty. Shopping engines vary greatly in size, algorithm, product categories and how they charge merchants. Chances are your site could receive a huge ROI on one CSE but not as much on another, so the best approach is to test your products in different venues, and adjust your strategy according to performance.
Google, a paid CSE, is a good starting venue for small and medium-sized businesses because it brings a lot of traffic. Businesses with larger marketing budgets may benefit from adding other paid engines such as Bing Shopping, Nextag, Pricegrabber, etc. When you purchase a CSE Management plan that includes cost-per-click engines, we will make budgetary adjustments as needed to maximize performance.
