“Constructor since it has launched has allowed me to get so much time back. Rather than having to focus on what new keywords I need to watch out for from the shift of one season or holiday to the next, its learning and adjusting on its own. No more fussing around with manual search suggestions, or synonyms. I am able to focus on true conversion strategy and how to get more people to these more optimal pages.”
