Marketing is working when it produces measurable movement toward business goals, not just activity. Useful signals include qualified traffic, calls, forms, booked appointments, sales opportunities, revenue, customer acquisition cost, conversion rate, and lead quality. Vanity metrics such as impressions, clicks, and followers can be helpful context, but they should not be the final scoreboard. A good measurement plan connects each channel to the next business step: visitor to lead, lead to opportunity, opportunity to customer, and customer to lifetime value.
Example
If SEO traffic increases but calls do not, the issue may be search intent, page conversion, phone tracking, or lead quality. If Google Ads leads increase but close rates fall, the campaign may need better keywords, negatives, landing pages, or qualification.
