Full Answer

Start with three measurable components: recovered conversions (typically 20-40% of currently invisible events), reduced CPA from better algorithm optimization, and improved ROAS from complete attribution data. The formula: (monthly ad spend × estimated data loss percentage × expected improvement rate) divided by monthly tracking solution cost. For a business spending $10,000/month on ads with 30% data loss, recovering even half that signal typically yields 500-2,000% ROI on the tracking investment within the first quarter.
