Milestone based. Make sure there are deliverables and that you are only shelling out equity in exchange for concrete value add. Is she going to get you written up in X publications? On X blogs? Is she going to be the sole driver of revenue? You can give her X% based on monthly or quarterly revenue targets. I think the right mindset is: if she does X she will be increasing the valuation by Y so I will be comfortable giving her Z%. Hmm wonder why I assumed they are a woman.
