# Bidding strategy Conviu has a tool up for all bidding strategies, ie cost-per-click (CPC) pricing in all comparison shopping sites. And you don't have to choose - you can apply a different approach to each part of your e-shop's assortment. You can set bidding according to: * required positions (so-called position targeting) * difference in prices compared to the competition * percentage of cost of turnover (PNO) * margins * stock availability * products in action * categories, manufacturers, brands * competition prices * top products Thanks to the connection to the Heureka.cz and Zboží.cz APIs, automatic cost-per-click optimization for individual products can take place up to 12 times a day, day and night, 7 days a week. Of course, you can also set a maximum cost-per-click and automatically turn off failed items. A poorly set bidding strategy can be costly. So we also offer the option to switch to Smart Bidding, which sets and evaluates bidding itself, according to ROAS (return on investment). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
