The offer is not differentiated from Canadian competitors
"Free estimate", "free consultation", and "book a call" are used across every service industry in Canada. They tell the visitor nothing specific about what they will receive or what makes the engagement worthwhile. Visitors arriving from paid campaigns — who came via a specific promise in the ad — arrive at an offer label that is less specific than the ad that brought them. The offer is the most important variable on the page and it is the one most commonly left unchanged.
