Two Systems With Two Different Gatekeepers
A strong LinkedIn profile and a strong CV are not the same document in different formats. They serve different gatekeepers, are evaluated by different criteria, and require different optimisation strategies. Conflating them produces a result that works adequately for neither.
LinkedIn's algorithm surfaces profiles to recruiters based on keyword density, connection proximity, and engagement signals. It rewards completeness, activity, and social proof. A recruiter finding you on LinkedIn has already cleared one filter — they searched for you, which means the vocabulary matched. The CV they then request faces an entirely different test.
Where the Disconnect Happens
In a sample of 200 candidates who reported receiving LinkedIn recruiter outreach but no subsequent interview progression, we found that 67% had CVs that scored below 45% on keyword match against the roles they were being contacted about. Their LinkedIn was surfacing them correctly — their CV was then failing the ATS test those same companies used.
The irony is that LinkedIn optimisation created false confidence. Candidates assumed that because recruiters were finding them, their job search materials were strong. The bottleneck had simply moved downstream.
"LinkedIn gets you found. Your CV gets you interviewed. Optimising one without the other solves half the problem."
Aligning Both Systems
The most effective approach treats LinkedIn and CV optimisation as complementary but distinct exercises. LinkedIn should be optimised for the vocabulary recruiters use when searching — job titles, skills, and industry terms in their search-facing language. The CV should be optimised for the vocabulary in specific job descriptions — mirroring the exact phrasing used in each posting you apply to.
LinkedIn vs CV — what to optimise differently
- →LinkedIn headline: use the broadest version of your target role title — what recruiters search for
- →CV headline: use the exact title from the specific job posting you're applying to
- →LinkedIn skills: add all relevant skills — completeness signals credibility to the algorithm
- →CV skills: only include skills that appear in the job description — irrelevant additions dilute keyword density
- →LinkedIn summary: written for a human who found you — context, narrative, credibility
- →CV summary: written for an ATS that's matching you — keywords, specificity, role alignment
