The most common LinkedIn mistake isn't a bad profile. It's a pasted one — the resume, uploaded wholesale, doing a job it wasn't built for.
The two documents look related and work completely differently. The resume is targeted, terse, and expires the moment you submit it. LinkedIn is discoverable, narrative, and permanent. Optimizing one with the other's rules wastes both.
The core difference: push vs. pull
A resume is pushed — you send it to a specific person for a specific role, and you control every part of that read: what they see, in what order, in what context.
LinkedIn is pulled — recruiters search it like a database, using titles and keywords, often before you know they exist. On a resume, you're making a case. On LinkedIn, you're making yourself findable and worth a second look.
Where the documents should diverge
- Headline. Resume: your target title, plainly. LinkedIn: room for a value statement — "Senior support lead · CSAT 4.8 across SaaS and fintech."
- Summary. Resume: two or three lines, rewritten per application. LinkedIn About: first person, several paragraphs, room for the story.
- Voice. Resume bullets are impersonal and clipped; LinkedIn can say "I" and carry some personality.
- Keywords. They matter more on LinkedIn, because search is the primary discovery path — but they belong inside narrative, not a noun dump.
- Shelf life. The resume is rebuilt per posting; LinkedIn should just stay current. A profile untouched for two years reads as a person who isn't engaged.
LinkedIn gets you found. The resume gets you the interview.
The division of labor
LinkedIn gets you found. The resume gets you the interview. Practically: write the LinkedIn profile once, well, and update it when things change. Tailor the resume every single time — and let the tailoring be its own job, not an upload. Tools built for that per-posting loop (Aptly, at tryaptly.app, is one) score one resume against one job description; LinkedIn, by design, can't do that work.
If your profile is currently a resume dump, fix two things first: the headline (it's what shows in every search result) and the About section (it's what people actually read). Those two pieces do most of the discovery work.
Same career, two documents, two jobs. Keep them separate and the profile stops being a stale copy — and the resume stops being a generic one.
