What Literary Agents Look For In A Manuscript

What Literary Agents Look for in a Manuscript

Market Fit and Concept Clarity

Agents scan for market fit in seconds. When a concept clicks, pages survive. When a concept wobbles, pages sink, no matter how clean the prose.

Lead with a sharp hook

Fiction lives or dies on one line: protagonist, goal, obstacle, stakes.

Nonfiction relies on problem, promise, audience.

Keep names and worldbuilding out of the hook unless fame or setting sells the book on its own. Clarity beats lore.

Declare your category and subgenre

Agents think in shelves. Align with retailer menus readers browse, not a vibe in your head.

Use concrete labels:

Add BISAC or Thema terms in your query metadata or proposal. One primary category, one tight subcategory. Stray categories confuse positioning and comps.

Quick exercise: open a major retailer, find the top lists for your lane, and pick the single best shelf for your book. If two shelves fit, choose the one with buyers, not the one with ego points.

Hit commercial word counts

Ranges signal professionalism and sales awareness.

Overlength often hides structural drift or indulgent backstory. Underlength often hides thin stakes or missing scenes. Trim or expand before querying. A strong sample still faces hard math at acquisitions, where printing costs and price bands rule.

Choose smart comp titles

Present two or three recent comps from the last two to three years. Match tone, audience, and shelf. Skip mega‑phenomena and films. Agents need a realistic sales lane, not lightning in a bottle.

Right:

Wrong:

Sourcing ideas:

Use comps to signal performance level and reader expectations, not to brag.

Promise something familiar, then twist

Readers buy a promise. Agents look for a fresh spin on a trusted frame.

One‑sentence USP templates:

Fill‑in prompt: "Readers who love [familiar element] get [fresh angle] through [specific device or lens]."

Fresh comes from specificity. Swap "unique magic system" for "body‑clock magic tied to sleep cycles." Swap "strong female lead" for "pregnant homicide detective in her third trimester."

Sanity‑check with the market

Write a one to two line elevator pitch. Read it aloud. No throat clearing. No life story. If breath runs out, the hook needs slimming.

Then reality‑check:

If answers lean soft, adjust the angle. Maybe the hook hides the real engine. Maybe the subgenre label needs a switch. Maybe the stakes need daylight.

Common missteps to avoid

A quick drill

Agents hunt for proof of fit. Show a sharp hook, a shelf, a realistic length, smart comps, and a twist that earns attention. Do that, and a full request moves from wish to likelihood.

Voice, Prose, and Page-Level Excellence

Agents feel your pages before they think about them. Voice hits first. Rhythm follows. Clarity brings the yes.

Keep voice and POV steady

Voice is choices. Diction, rhythm, attitude on the line. Pick one lens and stay inside it. If you write third person limited, stay glued to one mind per scene. No sudden access to someone else’s private thoughts. Readers sense a camera jump.

Watch for tense wobble. Pick past or present. Hold to it.

Head-hopping example, then fix:

One scene. One mind at a time. Interiority belongs to the viewpoint character.

Show, do not explain

Explanation flattens story. Evidence animates it.

Telling:

Showing:

Use concrete detail. Choose precise verbs. Swap “walked” for “limped, drifted, strode, shuffled.” Choose one that fits the moment. Trim qualifiers and hedging. They blur intent.

Subtext in dialogue beats statements of theme. Instead of “I am angry with you,” try action and implication.

Readers read between lines when you give them signals. Trust them.

Line-level clarity

Sentences should breathe. Mix short and long. Vary openings. Prune throat clearing. Start where heat begins.

Cluttered:

Clean:

Paragraphs carry beats. One idea per unit. White space is pacing. If your paragraph runs half a page, ask why.

Smooth transitions keep readers upright. Use threads. A repeated object. A question carried across a scene break. Do not rely on adverbs to glue fragments. Use logic and image.

Mini exercise:

Dialogue with purpose

Dialogue should reveal character and move plot. Skip exposition dumps and “as you know” exchanges. If both parties know the info, they would not say it.

Dump:

Purposeful:

Layer beats between lines. A glance at the door. A phone face down. A hand on the sink rim, whitening knuckles. Let the body argue while mouths try to stay polite.

Trim dialogue tags. “Said” disappears. Fancy tags draw attention. Use action beats to anchor speakers and mood.

Landing the opening

Start in scene. A person wants something concrete. Something blocks them. Micro-tension pulls the eye forward. You do not need a gunshot on page one. You do need a question in the reader’s mind.

Skip dream openings. Skip car rides unless the car ride explodes. Do not front-load backstory. Let history leak through choice and consequence.

A few clean starts:

Each gives a goal, a hitch, and a reason to turn the page.

Action: raise the line

Precision on the line signals authority. A strong voice convinces busy gatekeepers to lean in, sit down, and keep going. Keep the lens steady. Put truth on the page with detail and clean rhythm. Your pages will do the work.

Structure, Stakes, and Reader Payoff

Structure sells confidence. Stakes sell urgency. Payoff builds trust.

Fiction: spine, beats, and cause and effect

Start with goal, motivation, conflict. Protagonist wants something concrete, for a pressing reason, against a barrier that pushes back. Tension rises when each move brings cost.

Place the inciting event near 10 percent. A change lands, and the old plan fails. At midpoint, the path flips. New knowledge arrives, or power shifts. Near the end, the climax answers the core question. Yes or no. Win or lose. After that, a short beat for consequence and breath.

Causality glues scenes. Not this happened, then this happened. This happened, therefore the next thing followed. Or, this happened, but a new problem blocked progress.

Quick pass using the therefore or but test:

Mini example:

Every step triggers the next step. Pressure climbs. Cost rises.

Character arcs and genre promise

Readers invest in change. Arc shape varies by genre, yet payoff must honor the promise on the cover.

Track inner shifts with outer action. Courage replaces avoidance. Honesty replaces denial. Pride yields to trust. Mark those turns with choices under stress, not speeches.

Scene intent and value change

Give every scene a purpose. A scene should move a needle. Power, trust, danger, hope, respect, money. Choose the value, then change it.

Flat scene:

Alive scene:

End scenes with a hook. A new question, a fresh problem, a decision that feels risky. Readers turn pages for answers, not summaries.

Checklist for a scene pass:

Prescriptive nonfiction: promise, proof, and usefulness

Open with a tight thesis. One sentence, clear benefit, named audience. For example: A four-week strength plan for new mothers with no gym access.

Lay out a roadmap. Chapters build in logical order. Each one solves a step toward the promise.

Proof matters. Use recent data, case studies, field notes, and clear sourcing. Short callouts for key takeaways help busy readers act.

Voice signals authority and care. Speak to pain points without scolding. Respect readers’ time. Avoid fluff. End chapters with actions, checklists, or scripts. Readers should do something different after each chapter.

Sample skeleton:

Memoir: spine, reflection, and ethics

Memoir needs a narrative spine, not a scrapbook. Choose a central question. For example: How a teacher rebuilt a life after a public firing. Then select scenes which drive that question toward an answer.

Balance scene and reflection. Show what happened, then reflect with perspective. Reflection adds meaning beyond events. Readers seek recognition, not a diary.

Handle real people with care. Change names when needed. Compress timelines only when truth survives the edit. Avoid revenge on the page. If harm appears, show context. Consider legal review for high-risk material.

Prompt for focus:

Action: build momentum and expose gaps

Strong structure teaches agents to relax. Rising stakes keep attention locked. A clean payoff earns faith in your name on the next project.

Professional Polish and Submission Readiness

Sloppy presentation kills good writing. Polish signals professionalism before the agent reads a single scene.

Standard manuscript format: the invisible foundation

Format matters because agents read dozens of manuscripts weekly. Clean presentation reduces eye strain and removes barriers between reader and story.

Use 12-point Times New Roman, Garamond, or another serif font. Double-space everything. Set 1-inch margins on all sides. Indent paragraphs with the tab key, not multiple spaces. Number pages in the header or footer. Include your last name and manuscript title on each page.

Start chapters halfway down the page. Mark scene breaks with three centered asterisks or pound signs (###). No fancy fonts, colored text, or decorative elements. Resist the urge to make your manuscript "stand out" visually. The words do that work.

Save space by avoiding extra line breaks between paragraphs. Double-spacing handles readability. Agents notice bloated page counts from unnecessary formatting.

For electronic submissions, use standard paragraph indents. Avoid block formatting with line breaks between paragraphs unless submission guidelines specify otherwise.

Zero tolerance for presentation errors

Track Changes and comments scream "unfinished draft." Remove all editorial markup before submission. Delete stray highlighting, weird spacing, and random font changes.

Export a fresh copy from your master file. Hidden formatting glitches survive copy-paste operations. A clean export prevents mysterious line breaks and font shifts that distract readers.

Check page numbers. Verify chapter titles match your synopsis. Run spell-check, but don't trust it completely. "Their" passes spell-check when you meant "there."

Read the first page aloud after formatting. Awkward line breaks and spacing issues reveal themselves in speech.

Editorial readiness: layers of revision

Submit only finished work. Agents assume your best effort lives in the query package.

Start with developmental feedback from beta readers or critique partners. Address big-picture issues: pacing, character arcs, plot holes, structural problems. Fix major story issues before line editing.

Next, tackle line editing and copyediting. Check sentence flow, word choice, and clarity. Remove filler words. Strengthen weak verbs. Polish dialogue tags and action beats.

Create a style sheet. Track character names, spellings, ages, physical descriptions, and timeline details. Note capitalization choices for invented terms, places, or organizations. Consistency builds reader trust.

Final step: proofreading. Hunt typos, punctuation errors, and formatting glitches. Read backward sentence by sentence to catch mistakes your brain autocorrects during normal reading.

Consider professional editing if budget allows, but understand the difference between developmental editing (big picture) and copyediting (sentence level). Most manuscripts need both before submission.

Rights and permissions: legal housekeeping

Secure permissions for song lyrics, extensive quotes from other works, and lengthy passages from news articles or academic sources. Fair use covers brief quotes for commentary or criticism, but substantial excerpts need permission.

For nonfiction, cite sources properly. Include a bibliography or source notes section. Double-check facts, dates, and statistics. Agents notice factual errors and worry about liability.

Consider disclaimer language for memoir or narrative nonfiction: "Some names and identifying details have been changed to protect privacy." This covers minor alterations without misleading readers about major facts.

Document permissions in a separate file. Include contact information, fee arrangements, and usage terms. Agents need this information for contract negotiations.

Sensitivity considerations

If your work represents communities outside your lived experience, or addresses trauma and difficult topics, consider a sensitivity read from someone within those communities.

Sensitivity readers catch harmful stereotypes, inaccurate cultural details, and problematic language. They also flag missed opportunities for authentic representation.

This step matters for commercial reasons too. Publishers want books that reach wide audiences without causing controversy that hurts sales.

Budget for sensitivity reading during the revision process, not after agent submission. Address feedback thoroughly. Surface-level changes rarely fix deeper representation issues.

Submission guidelines: follow the recipe exactly

Each agency posts specific requirements. Read them twice. Print them if necessary.

Common variations:

Ignoring guidelines signals carelessness or inability to follow directions. Agents notice. Some reject automatically for formatting errors.

Create a spreadsheet to track requirements for each target agent. Copy-paste specific instructions to avoid mistakes when rushing through submissions.

Pre-submission checklist: the final pass

Export a fresh copy for each submission. Check these elements:

Formatting:

Content accuracy:

File management:

Agency-specific details:

Print your query letter and first page. Read them on paper. Screen reading misses errors that jump off printed pages.

Polish separates amateurs from professionals. Agents represent your work to editors, who represent it to readers. Clean presentation signals you understand the business and respect everyone's time. Your brilliant story deserves a professional wrapper.

Commercial Potential and Author Partnership Signals

Agents hunt for two things at once. A book readers want. An author they want to work with again. Give them both.

Show a clear path to readers

Know where the book sits on a shelf. Name the exact section a bookseller would choose. Fantasy. Domestic suspense. Upmarket women’s fiction. Narrative nonfiction about work and culture.

Now map discovery. Who already talks to your readers?

Mini-exercise: write two lines.

Be specific. “Everyone with a pulse” is not a plan. Three to five precise channels beats a vague list of platforms.

Series or brand potential, with a payoff now

Agents like future income. Readers like closure. Give both.

If you pitch book one of a series, promise a full meal, not a plate of appetizers. Resolve the core story question. Leave room for new problems, new villains, or a wider world.

Offer a one-paragraph series note in your query:

Example: “Three-book mystery series set in coastal Maine. Each case resolves within one book. The slow-burn romance advances across the series and reaches HEA in book three.” Short, clear, market savvy.

Nonfiction needs visible authority

Platform size matters, and the page still needs to earn trust. Show experience and insight in-scene.

Prove you know the subject. Use concrete cases with outcomes. Bring in original frameworks, not recycled listicles. Cite primary sources where possible and give clean notes.

On-page signals agents look for:

A smaller platform paired with uncommon clarity beats a massive following with thin content. Teach the reader from page one. Make usefulness obvious.

Think in subrights

Agents evaluate more than print. Audio, translation, and film or TV add value. Give them reasons to believe the story travels.

Audio loves strong voice, clean scene work, and dialogue which moves. Translation favors universal stakes, settings which do not rely on local in-jokes, and concepts which pitch in one line. Film and TV look for high-concept hooks, visual turns, and character engines which generate episode-level conflict.

Two quick filters:

If you have prior subrights experience or foreign editions, note it in your bio. If lyrics or brand-heavy material appear in the text, flag how you will handle permissions or swaps. Clean rights reduce friction later.

Partnership over the long term

Skill matters. So does temperament. Agents want partners who meet deadlines, revise with intention, and communicate like pros.

Signals you send before an offer:

A brief anecdote. Two writers received similar revise-and-resubmit notes. One replied the same day, set a timeline, delivered on time, and summarized the changes in one page. The other took three months without a check-in, then argued every point. Guess who moved to offer. The work matters. Process matters too.

What to include in your query

Give agents a snapshot of market fit and your partnership signals without bloat.

Keep it crisp. Two to three sentences per area, tops.

Quick self-audit before you hit send

Your pages sell the story. Your query sells confidence in the outcome. Put both to work.

Common Red Flags Agents See in Manuscripts

Agents read fast. They scan for reasons to say no. Remove the easy nos.

Off-kilter length and lopsided pacing

Word count signals market fit. Too short looks thin. Too long reads indulgent. Hit the range for your shelf, then shape the curve.

Two quick checks:

Fixes:

Soggy openings and backstory swamps

Slow starts lose agents. A prologue that dumps lore does not help. Neither does chapter one as a résumé.

Open in scene. Give the reader a problem in motion. Add one concrete desire. Add one obstacle. Sprinkle context later.

Red flag pages:

Fixes:

Mini-exercise: write your first page without any proper nouns beyond the protagonist’s name. Force clarity through action and image, not lore.

Genre and POV drift

Agents feel whiplash when the book pitches one thing, then reads like another. A YA voice tied to adult themes. A thriller that pauses for long literary interludes. A rom-com that forgets to be fun.

Pick the promise, then keep it. Tone, heat level, and on-page language should match category norms.

Common slips:

Fixes:

Clichés, tired beats, and theme on a soapbox

Tropes are tools. Clichés are shortcuts. Agents see the same beats all week, so give a fresh angle.

The greatest hits to retire:

Fixes:

Mini-exercise: write three new ways your scene could turn that keep the genre promise but surprise you. Pick the one that scares you a little. Readers will feel that energy.

Messy mechanics

Typos happen. A pattern of errors tells an agent the book needs days of line work before it can stand. Most do not have those days.

Usual suspects:

Fixes:

Line tip: cut filler words in a final pass. Sort of, really, very, that, began to, started to. Your sentences tighten by magic. The good kind.

Permissions and facts

A lyric can tank a deal. A sloppy statistic can kill trust.

Risk zones:

Fixes:

Nonfiction bonus: if you present a case study, change identifying details, secure consent where needed, and say so. Ethical handling reads on the page.

A quick rescue plan

Before you send pages, run this short drill.

Agents want to say yes. Make it easy. Give them a clean start, a confident middle, and a finish that pays the bill. Then press send.

Frequently Asked Questions

How do I validate market fit and write a sharp one-line hook?

Boil your book to protagonist + goal + obstacle + stakes and practise that as a one-line elevator pitch until it snaps. Use that line to sanity‑check against retailer Top 100 lists in your shelf — if the hook sits comfortably beside current leaders, you have basic market fit and concept clarity.

Test the hook with cold readers and a quick thumbnail study of the top 20 covers in your niche; if the concept reads as off‑brand, sharpen the promise or change the shelf you target before you query or spend heavily on production.

What commercial word count should I aim for in my genre?

Follow typical commercial word counts as a signal of professionalism: adult contemporary 80–100k, romance 70–90k, thriller 75–95k, epic fantasy 90–120k, memoir and narrative nonfiction 70–90k, middle grade 35–55k. These ranges matter for pricing, production and agent expectations.

If your manuscript sits outside the range, either tighten or expand to address structural issues — overlength often hides drift; underlength can indicate missing scenes or weak stakes — before submitting or pitching to publishers.

How do I choose smart comp titles and use them in a query?

Pick two or three recent comps (published in the last 2–3 years) that match tone, audience and shelf—avoid mega‑phenomena and films. Phrase comps as "for readers of X and Y" to signal realistic sales lanes rather than aspirational name‑dropping.

Source comps from publisher catalogues, Edelweiss or current top lists and be prepared to justify why each comp is relevant; accurate comps help agents see market positioning immediately and speed a full request.

What makes a strong opening and how do I avoid a backstory swamp?

Open in scene with a clear immediate desire and a problem in motion; avoid prologues and long patches of exposition. Aim to land an inciting event by roughly 10% and let backstory drip in through action and consequences rather than info dumps.

Try the "first-page test": remove non-essential proper nouns and read aloud. If the page still delivers a hook, it’s working; if it relies on lore or exposition, tighten the opening until the tension carries the reader forward.

What does submission readiness mean — what's on the pre-submission checklist?

Submission readiness means clean standard manuscript format (12‑pt serif, double‑spaced, 1" margins, indented paragraphs), no Track Changes or comments, a consistent style sheet, and a polished first sample that reflects developmental and line edits. Include a short synopsis and tailored query per agent guidelines.

Also confirm permissions for any quoted material, run a final proofread (read aloud or on paper), and follow each agency’s submission rules exactly — a submission readiness checklist prevents avoidable rejections for presentation errors.

What common red flags do agents see and how can I fix them?

Typical red flags include off‑range word counts, slow openings, POV or tense drift, clichés, and persistent mechanical errors. Agents also spot risky permissions (song lyrics) and factual sloppiness. These issues signal extra work and cost to the acquiring house.

Fixes: trim 10–15% starting with filler, run a POV/tense sweep, replace clichés with specific twists, do a rigorous copyedit, and remove or licence risky quotes. A clean, focused first 10 pages makes a big difference.

When should I hire sensitivity readers or secure permissions?

Bring in sensitivity readers during revision if your work represents communities beyond your lived experience or tackles trauma; they flag harmful stereotypes, factual gaps and language issues that can derail sales and reviews. Budget this into your revision timeline so you can act on feedback fully.

Secure permissions for song lyrics, long quotations, or brand‑dependent material before submission; if you can’t obtain rights, remove or paraphrase the material. Keeping permissions and sensitivity reads ahead of submission reduces legal and reputational risk.
