Just Heck My Landing Page Up 🤜🏽💥

Answer: This spreadsheet will help you think through all the facets of a job offer that you should be weighing and considering outside of just pure compensation.
Problem: People make huge life decisions on limited information without reason. They go off of a gut feeling instead of logic and that doesn't always end well.

Nice - this, condensed, could lead to a very compelling value proposition.

How can I qualify myself as a user?
Answer: You're a potential user if you're considering changing jobs or are in the process of interviewing/offer period.
Problem: You're not prepared to have an informed conversation about your potential future job or career move with a new employer your current employer.
I wonder if you could be more targeted here. Presumably you don't mean to include anyone considering a new job. Is there a type of job your tool is targeted at? A particular region or industry perhaps? Eg is this something a fast food worker, bank manager, or lawyer would use? Is it more for white collar or blue collar jobs? And for your target user, what emotions do they experience when choosing between jobs - frustration, being overwhelmed, decision fatigue, etc? Being more targeted might help with your website copy and the solution as well.

One idea (which you're very welcome to ignore) - I see your spreadsheet acting like a career coach almost, which is something people already spend $$$ on. Perhaps you could use that kind of language on your page: "coach", "guide" etc?

Definitely have a look at Harry Dry's marketing tips on landing pages, I think it'd be very helpful, particularly #4: https://www.indiehackers.com/post/my-twitter-account-reached-100-000-heres-7-of-my-favourite-marketing-tips-and-a-little-story-dcc40fbedf
