How to Determine Competitive Salaries for Specific Positions

Hi everyone! I’m working with a client who is considering offering $30/hour for a Sales Development Representative (SDR) with 10 years of experience in the light industrial sector. This seems relatively low, especially without considering performance bonuses. I’m curious about how you all gather information on what other companies are paying for similar positions.

I’d like to equip my client with a solid understanding of salary expectations, such as, “To attract a CEO, you should budget at least $130k in this state,” or “High achievers in XYZ roles typically command around $180k.” Any suggestions on how to source reliable salary benchmarks to help set proper expectations? Thanks in advance for your insights!
