In two words, probably not. While Google Ads often generates a higher ROI than other methods of advertising it is no silver bullet on its own. If your product/service is not selling you probably have a gap in one or more of the 4 P’s of marketing; product, price, promotion, and placement.
We’d be happy to discuss your offer to see if we believe you are Google Ads "ready" and if not we may be able to help you get ready.
