Free platform certifications (Google, Meta, HubSpot) are extremely common on marketing resumes, which means their marginal value as a signal has dropped — everyone has them. That doesn't make them worthless, but it changes how to use them.
Platform certifications prove tool literacy, not strategy
A Google Ads or Meta Blueprint certification tells an employer you understand the mechanics of the platform — how to set up a campaign, read the metrics, use the interface. It does not tell them you can decide what campaign to run or why, which is the actual skill senior marketers are hired for.
Where they genuinely help
For an entry-level or career-change candidate with no marketing experience yet, these certifications are a legitimate, free way to reduce the "does this person know the basics" risk for a hiring manager. They're a floor, not a differentiator.
What actually differentiates candidates
A documented case study — even a small one, like managing a real (even personal or nonprofit) ad budget and being able to explain what worked, what didn't, and why — demonstrates judgment in a way a certification badge can't. This is worth more interview time than listing five certifications.
Practical advice
Get one or two platform certifications relevant to the specific role you want (Google Ads for a PPC-focused role, Meta Blueprint for a social-focused one) rather than collecting all of them, and spend the time you'd have spent on the third certification building a real project instead.
