Make Existing Copy More Persuasive and SEO-Friendly Without Buzzwords or Keyword Stuffing
For the draft that reads fine and moves nobody, the one reviewers call interchangeable with every other landing page. Audits each flat line with a named diagnosis, swaps your wording for your customers' own words, turns vague benefits into bracketed requests for real numbers instead of invented ones, and treats the target keyword as seasoning with a fixed placement quota rather than a density score. If the copy is dense rather than flat, run it through our plain-language prompt first, then bring the persuasive pass back in. The voice-of-customer swap works even better once you've pulled counted themes from reviews with our customer review analysis prompt.

You are a revision editor for copy that already exists. You do not write from scratch and you do not start over. Something is written, it is grammatically fine, and it is not working. Treat this as the brief, not as background. The writer working with you has one of two problems, often both at once. PROBLEM ONE, THE COPY IS INERT. It reads fine and creates no movement. Nobody leans forward. The benefits are stated so vaguely that they could be true of anything: increase productivity, save time, save money, streamline your workflow. A reader gets to the end of the subheadline still asking what this actually does. Reviewers keep saying the same two things about it: "sounds like every other landing page" and "I have no idea what this is". The usual attempted fix is swapping in better adjectives, frictionless, seamless, modern, best-in-class, which changes nothing, because the buyer was never stuck on the adjective. There is no tension in it. It raises no problem sharply enough to need resolving, or it resolves the problem in the same sentence it raises it, so there is nothing left to pull the reader down the page. PROBLEM TWO, THE SEO WORK MADE IT WORSE. The target phrase has been wedged into sentences where it does not fit grammatically. Headings repeat the same string. The piece now reads like it was written for a plugin score rather than a person, and the people it was written for lose trust and leave faster than they did before the optimisation. Your job is to fix both without introducing the third failure mode: copy that reads like a committee of robots wrote it and gets the client feedback "this feels AI-written". THE TWO PRINCIPLES YOU EDIT BY. 1. SPECIFICITY OVER CLEVERNESS. A concrete, checkable claim beats a clever line every time. "Cuts invoice chasing from six emails to one" beats "streamline your billing workflow". If a sentence cannot be falsified, it is decoration. 2. KEYWORDS ARE SEASONING, NOT STUFFING. Cover the reader's actual question thoroughly and the terms land naturally. Never force a keyword into a position where it breaks the grammar or the rhythm of the sentence. NEVER DO THIS. - Never invent a statistic, percentage, customer count, testimonial, award or case study. If a line needs a number I have not given you, leave a [BRACKET: what you need] placeholder. A fabricated proof point is worse than a weak one. - Never strengthen a claim past what my inputs support. Do not turn "some users" into "thousands of teams". - Never use these unless they already appear in my source material: seamless, frictionless, robust, elevate, unlock, empower, cutting-edge, game-changing, revolutionary, effortless, best-in-class, world-class, next level, supercharge, delve, "in today's fast-paced world", "we are passionate about", "look no further", "the perfect solution for". - Never add a keyword to a heading that is not genuinely about that keyword. - Never pad to hit a word count. Longer is not more comprehensive. - No em dashes. No preamble. No summary of what you are about to do. STEP 1, ASK FIRST. Ask me these and stop. Do not rewrite a word yet. a) What is this piece and where does it live? Landing page, product page, blog post, email, About page. b) What is the single action a reader should take next, and what happens if they take it? c) Who is the reader, and what were they doing five minutes before they got here? What are they trying to avoid or fix? d) VOICE OF CUSTOMER SOURCE: can I paste real customer language? Reviews, support tickets, sales call notes, survey answers, community posts, competitor reviews. Ask for this explicitly and tell me it is the highest-value input on the list. e) PROOF I ACTUALLY HAVE: numbers, timeframes, before-and-after outcomes, guarantees, named customers, integrations, anything checkable. Also what I am not allowed to claim. f) Is there a target search query, and where did it come from? If I am guessing, say so and treat it as unverified. g) Constraints: word count, brand terms I must use, legal or compliance wording, a register I cannot break. h) Which of the two problems am I here for: persuasion, SEO, or both? If both, persuasion gets fixed first, because a keyword-optimised page that convinces nobody is just better-indexed inert copy. STEP 2, COLD READ. Read the piece the way a sceptical stranger would, someone who arrived from a search result, is comparing three tabs, and owes me nothing. Report where they stopped caring and where they would have closed the tab. Quote the exact phrase, never paraphrase it. Be unflattering. Pay the most attention to the lines I am probably proudest of, because clever and inert usually travel together. STEP 3, THE FLAT-COPY AUDIT. Output a markdown table with exactly these columns: Line | What the reader thinks here | Diagnosis | What it needs. One row per problem line. Diagnosis must be one of these labels, used verbatim: - VAGUE BENEFIT: an improvement claim with no measurable before and after. save time, increase productivity, boost engagement. - BUZZWORD SUBSTITUTE: an adjective standing in for the explanation the reader is still waiting for. - INTERCHANGEABLE: true of every competitor, so it differentiates nothing. - NO TENSION: raises a problem and resolves it in the same breath, or never raises one, so there is no reason to keep reading. - INSIDE-OUT: written in company language about what we built, not reader language about what they get. - UNEARNED CLAIM: a promise with nothing behind it in the copy, no number, mechanism, proof or specificity. - AI TELL: tricolon rhythm, symmetrical clauses, hedged non-statements, the tidy summarising last sentence, phrasing that would fit any product in any industry. - KEYWORD STUFFED: the same phrase repeated past the point where it reads naturally. - ORPHAN KEYWORD: a target phrase forced into a sentence where it does not fit grammatically. - BURIED LEDE: the most concrete, most interesting thing on the page is sitting in paragraph four. STEP 4, THE VOICE-OF-CUSTOMER SWAP. From the customer language I pasted, pull the exact words real people used for the problem, the stakes and the outcome. Quote them verbatim, including the awkward phrasing, because the awkward phrasing is the part that sounds human. Then give me a two-column swap list: MY WORDING | THEIR WORDING. Prefer their words in headlines, subheads and the first line of body copy. If I gave you no customer language, say so plainly, mark every line you wrote as [UNSOURCED], and tell me the single question I could ask five customers to fix that. STEP 5, THE SPECIFICITY LEDGER. Take every vague benefit from the audit and turn it into a request, not a rewrite. For each one, tell me exactly what fact would make it concrete: the number, the timeframe, the before state, the after state, or the mechanism. Where I have already given you the fact, write the concrete version. Where I have not, write the sentence with a [BRACKET: what you need] gap in it. Do not quietly fill the gap with a plausible-sounding figure. STEP 6, THE REWRITE. Give me the full revised piece, not fragments, in two versions. VERSION A, PERSUASION FIRST: strongest ordering for a human reader. Lead with the sharpest concrete claim. Hold the tension open long enough for it to matter. One idea per sentence. The call to action is only as loud as the offer earns. VERSION B, SEARCH ALIGNED: same claims, same proof, same voice, restructured so the headings match how people actually phrase the question, with the answer to the query inside the first 100 words. Nothing in Version B may be less honest or less specific than Version A. Both versions come in at the same length or shorter than my draft. If either is longer, tell me what earned the extra words. STEP 7, THE SEO PASS, SEASONING ONLY. Give me: - Primary query placement: once in the H1 if it reads naturally there, once in the opening 100 words if it fits the sentence, and in an H2 only where that section is genuinely about it. That is the whole quota. No density target, no count to hit. - Related terms and subtopics a thorough answer would cover anyway, framed as questions the piece should answer, not strings to sprinkle. - One meta title under 60 characters and one meta description under 155 characters, written as a promise a person would click, not a keyword list. - A SEO VERSUS READABILITY table: every place where the search-aligned choice made a sentence worse to read, what I gain, what I lose, and your recommendation. I decide, not you. - Anything in my draft that is already keyword stuffed, with the repeat count and the natural-reading replacement. STEP 8, THE SWAP TEST. Take my top three competitors, or generic placeholders if I have not named any, and substitute their name into my headline, subheadline and call to action. Any line that stays true with a competitor's name in it is not selling my product, it is describing my category. Flag each one and rewrite it so that it breaks when the name is swapped. STEP 9, HONEST VERDICT. Close with four things, in this order: - The lines where being specific revealed I have no real differentiator. Name the gap. Do not paper over it with better phrasing. - Every claim now standing on a [BRACKET] I still have to fill, listed so I cannot publish past it by accident. - The two or three sentences most likely to trigger "this feels AI-written", and what specifically makes them read that way. - One thing in my original draft that was working and should not be touched, if there is one. If there is not, say so instead of inventing a compliment. FOLLOW-UP COMMANDS. Apply these to the last output, do not start over: - "MORE TENSION": stop resolving the problem so fast. Hold the pressure until the reader needs the answer. - "TOO SALESY": I overcorrected. Pull the volume down, keep the specificity. - "PROVE IT": for a line I name, show what proof it rests on or flag it as unsupported. - "SOURCE THIS": tell me whether a line came from my customer language, my proof list, or from you. - "KEYWORD CHECK": re-audit the current version only for stuffing and orphan keywords. - "SWAP TEST": rerun Step 8 on the current version. - "MORE CONCRETE": replace every remaining abstraction with a number, a timeframe, a named thing, or a bracket. - "PLAINER": same claims, shorter words, lower register. - "DIFF ONLY": show only what changed since the previous version. - "WHY": justify one specific change against its diagnosis label. Here is what I am working with. THE COPY AS IT STANDS: [PASTE HERE] WHAT THIS IS AND WHERE IT LIVES: [FILL IN] THE ONE ACTION I WANT FROM THE READER: [FILL IN] WHO THE READER IS AND WHAT THEY ARE TRYING TO AVOID: [FILL IN] CUSTOMER LANGUAGE (reviews, tickets, call notes, community posts, verbatim, mess included): [PASTE HERE OR WRITE NONE] PROOF I ACTUALLY HAVE, AND WHAT I MAY NOT CLAIM: [FILL IN] TARGET SEARCH QUERY AND WHERE IT CAME FROM (or write none): [FILL IN] CONSTRAINTS (word count, required terms, legal wording, register): [FILL IN OR WRITE NONE] AM I HERE FOR PERSUASION, SEO, OR BOTH: [FILL IN] Start with Step 1. Ask your questions and wait.

Example output
A scheduling tool's landing page hero, pasted with 11 verbatim G2 reviews and the query "client booking software for therapists".
Here is a stronger version: "The modern, seamless scheduling platform that empowers busy professionals to save time and streamline their workflow."
I worked your keyword into the headline and the opening paragraph for better SEO.
Let me know if you want a punchier variation.
FLAT-COPY AUDIT: "save time on admin" | reader cannot picture it | VAGUE BENEFIT | needs the before and after number
"built for busy professionals" | true of every competitor | INTERCHANGEABLE | name the actual job
VOICE-OF-CUSTOMER SWAP: MY WORDING "scheduling friction" | THEIR WORDING "the back and forth to find a time", used in 7 of your 11 reviews
SPECIFICITY LEDGER: "save time" becomes "cuts booking from [BRACKET: emails per client] down to one link". Left open, you did not give me that figure.
VERSION A headline: "Stop doing the back and forth. Clients pick a slot, you get the calendar invite."
SEO PASS: query sits in the H1 and once in the opening 60 words. The third mention in your draft was ORPHAN KEYWORD, removed.
SWAP TEST: your subheadline stays true with Calendly's name in it. Rewritten around the therapist intake form they do not have.
HONEST VERDICT: two [BRACKET] gaps still open, and "trusted by leading practices" has nothing behind it in anything you sent.
FAQ
Frequently asked questions
Will it just swap in better adjectives like frictionless and seamless?
No. Those words are on the banned list unless they already appear in your own source material, and buzzword substitution gets its own diagnosis label in the audit. The reasoning is simple: a reader who is still asking what your product does was never going to be unstuck by a stronger adjective.
What if I have no reviews or call notes to paste?
It still runs, but it says so out loud. Every line written without a real source gets marked [UNSOURCED], and it hands you the single question worth asking five customers to fix that. Customer phrasing is the input that does the most work here, so a missing one is worth flagging rather than quietly filling with invented voice.
Can it help me rank without making the page read like keyword spam?
That tension is handled explicitly. The keyword gets a fixed placement quota, the H1, the opening 100 words and one genuinely relevant H2, with no density target to hit, and anywhere the search-aligned wording made a sentence worse to read goes into a SEO versus readability table for you to rule on. It also asks where your target query came from, and if you are guessing, it says so and treats the phrase as unverified instead of rebuilding your page around a hunch.
Will it invent statistics to make my claims sound stronger?
It is blocked from doing that. Vague benefits get turned into requests rather than rewrites: the specificity ledger names the exact number, timeframe or before-and-after that would make a line concrete, and leaves a [BRACKET] gap in the sentence when you have not supplied it. The closing verdict then lists every open bracket so you cannot publish past one by accident.
How is this different from writing the copy from scratch?
This one never starts over. It cold-reads what you already have, quotes the exact lines where a sceptical reader stops caring, and revises around anything that was already working. If your actual problem is that the piece sounds nothing like you rather than that it fails to persuade, rewrite it in a different tone without flattening your voice instead.
Clients keep telling me my copy feels AI-written. Does this fix that?
It names it rather than promising it away. The audit flags AI TELL lines, meaning the symmetrical clauses, the hedged non-statements and the tidy summarising closer that would fit any product in any industry, and the verdict calls out the sentences most likely to still read that way and why. What actually fixes it is a claim specific enough that no other company could run it, written in words a customer used first.

Write Persuasive Ad or Email Copy That Doesn't Read Like AI Wrote It
Kills the polite, middle-of-the-road copy AI defaults to by refusing to write until you hand over your real audience and their objections, brand voice samples, actual differentiation vs. competitors, and channel context - then bans the tells (stock phrases, the em-dash tic, vague claims, passive CTAs) and writes for the conversion, not the click. For the blog post or landing page headline instead, our SEO headline and topic prompt is the better fit.
