Effective Field Theories (EFTs) are a powerful tool for investigating the presence of new physics beyond the Standard Model. I will briefly review the status of the Standard Model Effective Field Theory and discuss a few aspects of how its parameters can be constrained with global fit analyses, while trying to minimize the assumptions on UV physics. As a case study I will show the results of a fit to electroweak data, that exhibits instructive features, among which the presence of two combinations of Wilson coefficients that remain unconstrained when the analysis is restricted to 2 → 2 scattering processes and whose origin can be understood in terms of a reparameterization invariance.
