What a great question.
Develop an instinct for researching, learning, and deeply understanding people's problems in their respective industries.
We all know that owners/founders wanna increase revenue and cut costs - but the mechanisms for that in each industry would be different.
For a business owner in the medical field, that might look like being on more insurance providers' panels so they can take on more patients/clients.
For an owner/founder in the ecom space, more efficient ad spend allocation would help them both increase rev while reducing ad costs (double whammy), and whatever product you're marketing to them should be framed as an effective means to that end.
Same for when you're targeting the finance guy, the HR lady, and the operations folks.
Study these verticals and industries deeply, understand the work-related pain-points they suffer everyday + the goals/objectives they're trying everyday to achieve, and how to connect both in your copy (messaging angles).
Developing and training that instinct will give you a huge edge over other GTMEs who get confused about building a full GTM strategy when they're given a new client to handle, and end up writing generic copy and building lists with inaccurate targeting, and don't frame the offer in a way that would be attractive to the target persona(s).
