DYNAMIC RE-MARKETING ADs
AdWords offers a dynamic remarketing model. But there are parts in which it lacks design, targeting, and advertising network. There are special dynamic remarketing systems built to serve this purpose and to provide better conversion rates for advertisers. For example, Criteo. The advertising network and advertising models of such special systems have been further expanded and developed. That's why conversion rates can be higher. It is a very effective advertising channel for e-commerce sites.
