2. It’s impossible to get a like-for-like comparison with crowdsourced salary data
“I'd say 50% of founders don’t want their team to pay for a benchmarking provider because they believe you can crowdsource that information. It's a common opinion that you can use secondary sources like LinkedIn and Glassdoor,” says Alistair Fraser, Founder of Justly.
Crowdsourced salary data is free to use, so it’s understandably tempting. But that isn’t the only reason CEOs and founders choose to use them: they also believe they can get the same quality results, too.
This often comes from a lack of understanding of the value of reliable salary benchmarking data – and the difference between this and crowdsourced salary data.
Secondary data sources are based on user-reported data.
For instance, Glassdoor asks employees to submit their salary, and use this self-reported data to produce ‘average’ salaries for each role. With LinkedIn or other job boards, companies will often list the salary range for a role within the advert which is free to use.
However, because the salary information is self-reported of this, there is no way of verifying the benchmarking data is accurate, up-to-date, or even correct.
Plus, user submissions make accurate job levelling a major issue. Job titles and organisation structures can vary significantly, and there’s no way of knowing the context of a user’s submission, making direct comparisons impossible.
In the below Glassdoor example, we can see that Software Engineer salaries in London range from £45,000-£76,000 per year. Despite a high number of salaries being submitted, there’s no way to verify that input is accurate or what level of seniority this range reflects. Organisations also level employees differently, making it impossible to know if it’s an accurate comparison to your levelling framework.
