Consultation: assumes a share of bio link taps head to the Create with Lane & Kate consultation path, inquiry conversion of 25–40% on high-consideration custom work, and a typical custom engagement engagement (ring plus band) inside the $1,800–$3,000 first-year range.
Gift: assumes a share of taps head to the online shop, new-customer conversion of 1–3%, and a typical designer or everyday fine-jewelry order at $400–$900 first-year with modest repeat.

The midpoint gives you an expected impact to plan around; the range shows the honest spread. As Bitly per-link tracking and your own data land in Q3, both the midpoint and the range tighten.
