Start with the decision, not the product.
Most CV advice online treats every job seeker the same. That is why people either overpay for help they do not need, or keep tweaking a document that needs a more serious intervention. The right choice depends on three things: how close your CV already is, how competitive the role is, and whether you can confidently turn feedback into edits.
A free CV checker is the best first step when you want a fast, low-risk diagnosis. It can flag common ATS and recruiter issues: missing role keywords, vague bullet points, weak section structure, overlong summaries, formatting choices that may parse poorly, and places where your impact is not measurable. If your CV is already current and you mainly need to find obvious gaps, the free score may be all you need.
A paid resume review becomes useful when the problem is no longer just “what is wrong?” but “what should I fix first?” A good review should prioritise changes, explain why the CV is not landing interviews, and connect your LinkedIn profile to the same career story. It is especially valuable if you are applying regularly, getting few callbacks, or suspect your experience is stronger than your application suggests.
