SEO / Content
8 toolsPut a dollar figure on organic search. Value the traffic you already earn, forecast what a ranking improvement is worth, work out when a content investment pays itself back, and size how much content a traffic goal actually needs.
Conversion / CRO
8 toolsBefore you buy more traffic, find out what the traffic you have is already worth. Test sizing, significance, funnel drop-off, checkout leaks, and the revenue hiding behind a one-point conversion-rate lift.
Email Marketing
5 toolsEmail is measured in revenue per send, not open rate. Value a subscriber, value the list, size the return on a campaign, and check whether sending more often actually earns more.
Social / Influencer
6 toolsRate cards are guesses until you run the numbers. Price a partnership on real engagement, compare creators on cost per engagement, and work out what a social campaign returned.
Ecommerce
4 toolsStore economics: average order value, repeat purchase revenue, free-shipping thresholds, discount profitability, and the cost of an abandoned cart.
Agency / Freelance Pricing
4 toolsPrice the work so it's worth doing. Set an hourly rate that covers non-billable time, size a retainer, mark a project up correctly, and find out which clients are actually profitable.
