A resume summary sits at the very top, which means it gets read first — and often weighted more heavily by both human reviewers and certain ATS ranking models. Here's a structure that works without sounding like a keyword dump.
Sentence 1: who you are, professionally
State your role and years of experience plainly. "Marketing manager with 6 years of experience in B2B SaaS" — specific, no fluff.
Sentence 2: your strongest, most relevant accomplishment
Pick the single accomplishment most relevant to the job you're applying for, with a number if possible. "Led a rebrand that increased qualified leads by 35% year over year."
Sentence 3: what you're looking for or bring next
Connect to the role. "Looking to bring that growth-marketing experience to an early-stage team." This sentence is optional — skip it if it feels forced.
What to avoid
Skip vague phrases like "results-driven professional with a passion for excellence." They add length without adding information, for a human reader or an ATS keyword scan.
