In order to use match settings and increase return simultaneously, you’ll have to understand a few things about match settings and search queries. One is that the level of impressions significantly decreases for phrase and exact match versions of keywords. And secondly, applying match settings to keywords should be done only with the intention of lowering “high” conversion costs or slowing the amount of clicks to conform to a limited daily budget.
When attempting to lower high conversion cost, it is important that you take all the preceding steps to lower conversion cost before applying match settings. Match setting will likely result in lower traffic and consequently lower sales volume. If you race ahead and apply match settings prematurely, you might forgo the opportunity to lower conversion cost without lowering traffic and sales.
