Job ad readability: how to check (and fix) a hard-to-read posting
Dense, jargon-heavy job ads lose candidates in the first 30 seconds. Here's how to run a readability check on a job posting and the concrete edits that lift your grade level, apply rate, and search visibility.
Candidates spend about 30 seconds skim-reading a job ad before deciding whether to apply. If yours reads like a legal contract — long sentences, dense jargon, a wall of unbroken text — you lose the best people before they reach "how to apply." Readability isn't a nice-to-have; it's the difference between a posting that converts and one that quietly underperforms. Here's how to run a readability check on a job ad and fix what you find.
What "readability" actually measures
A job ad readability checker scores your text against standard formulas — Flesch Reading Ease and Flesch-Kincaid Grade Level are the common ones — that estimate how hard the writing is to parse. Grade level is the most useful number: it tells you the years of education a reader needs to follow your posting on the first pass.
The target for a job ad is an 8th–10th grade reading level. That isn't "dumbing it down" — the clearest professional writing in the world (news, product copy, the best internal memos) lands in exactly that band. A posting at grade 15+ isn't more impressive; it's just harder to read, and it filters out great candidates who are busy, reading on a phone, or scanning between meetings.
The four things that wreck a job ad's readability
1. Sentences that never end. The single biggest driver of a high grade level is sentence length. A 40-word sentence with three subordinate clauses is a readability killer. Aim for an average under 20 words, and vary the length — short sentences create rhythm and let key points land.
2. Corporate jargon and acronyms. "Leverage cross-functional synergies to drive stakeholder alignment" says almost nothing, and every internal acronym (KPI, OKR, your product codenames) forces the reader to translate. Write the plain-English version: "work with other teams to reach shared goals."
3. Walls of text. Two 150-word paragraphs of responsibilities read as noise. The same content as scannable bullets, grouped under clear headers ("Responsibilities," "Requirements," "Benefits"), reads in seconds. White space is a readability feature.
4. Passive, abstract voice. "The successful candidate will be responsible for the management of…" is longer and vaguer than "You'll manage…". Second person ("you") and active verbs shorten sentences and speak directly to the reader.
A 60-second readability fix
1. Read the first sentence out loud. If you run out of breath, split it.
2. Delete the top five buzzwords. Replace each with the plain word you'd use in conversation.
3. Turn every responsibility paragraph into a bulleted list.
4. Change "the candidate will" to "you'll" throughout.
5. Add section headers if the posting is one long block.
Those five edits alone typically drop a posting two to three grade levels.
Why readability also helps you get found
Readability isn't only about the humans who read your ad — it's a discoverability signal too. Postings that are clear and well-structured hold attention longer and earn fewer instant bounces, and that engagement feeds search ranking over time. Clear headers and plain keywords also make it easier for Google and job boards to understand what the role actually is. A readable posting and a discoverable posting are usually the same posting.
