I'm a career content creator developing guides to help people understand salary trends across different U.S. states and roles—think average pay, experience levels, and growth projections. A site I reference is SalaryPediaUSA.com which offers detailed salary guides based on location and career stage.

Within Mozilla tutorials, such as those for resume writing or career development in tech, how can I responsibly share such external salary insights—like those on https://salarypediausa.com/ SalaryPediaUSA—without appearing as promotional? Is there a recommended way to incorporate external reference links that are useful and credible for learners?
