Most people send the same resume to every advert and then wonder why so few replies come back. The fix is not a fresh rewrite each time. It is a short edit, done the same way every time, to the part of the page that gets read first.
Fifteen minutes is enough, if the minutes are spent in the right order. Set a timer. The timer matters, because this work stretches to fill whatever time you give it, and an evening spent polishing three sentences is an evening not spent applying.
Minute 0 to 3: read the advert twice
First pass, read it like a person. What is this job actually about, and what would you be doing on a normal Monday?
Second pass, read it like a list. Copy out every skill, tool and phrase that describes the work. The lines in the opening paragraph and under requirements are the ones that count. The rest is usually filler: the paragraph about the company being a family, the long list of benefits, the sentence about a fast paced environment. Skip all of it for now.
Do not touch your resume yet. Reading and editing at the same time is how the first ten minutes disappear.
Minute 3 to 6: put their words next to your proof
Take that list and write one short line next to each item, describing what you did that proves it. Not a sentence for the resume, just the facts for you: the system you used, the number you moved, the size of the team, the deadline you held.
Some items will have nothing next to them, and that is the most useful part of the exercise. It shows you exactly what you cannot honestly claim, and it tells you what to leave out.
If four or more items are empty, do not apply today. Look for a similar advert a step lower, or spend the week on the one skill that keeps coming up. A tailored resume cannot invent history.
Minute 6 to 10: edit the top third of page one
The top of the page is what gets read first and often what gets read most, so this is where the four minutes belong.
Three changes, in this order.
The summary line. Rewrite it using their nouns. If the advert says payroll reconciliation, your line says payroll reconciliation, not finance admin. Two lines is plenty.
Your recent bullets. Reorder them so the two most relevant sit at the top of the role. You are not deleting the rest, only changing the order they are read in.
The skills line. Match the words they used. If they write Power BI and you write dashboards, put Power BI first, because that is the string being looked for.
That is it. Do not rewrite the middle of the page in this window. It will not be read closely enough to be worth the minutes.
Minute 10 to 13: cut, do not add
The urge at this point is to add something. Resist it. Tailoring is mostly removal.
Cut the jobs with nothing relevant in them, or shrink them to a single line. Cut school results from twenty years ago if you have worked since. Cut hobbies, unless one is genuinely connected to the role. Cut the objective sentence at the top, which says nothing a reader cannot guess from the job you applied for.
Every line you remove gives the important lines more room.
Minute 13 to 15: the last three checks
Check the file name. First name, last name, role, saved as a PDF, so the recruiter's folder of downloads stays readable and so your file does not arrive with an old draft's name on it.
Check the layout. One column, real text, no text sitting inside an image. If you cannot select a word with your cursor and copy it, the software reading applications cannot read it either.
Check your email address and phone number by reading them out loud. A single wrong digit is the most expensive typo in this whole routine.
Then send it, and stop. Perfection is not the goal of a fifteen minute edit.
Why this works at all
Because you are editing, not writing. The first genuine resume takes hours. After that, each advert is a short edit against a stable base, and the base only changes when something real in your history changes.
Keeping the base stable has a second benefit. When you are not rewriting everything at once, you can tell what actually made a difference between one application and another.
One step is hard to do by eye, which is spotting the words from the advert that are missing from your resume. The free ATS checker at resumeon.io/tool/ats-checker does that check for you: paste the resume and the advert and it shows the match score and the exact keywords the screening software looks for. Use it before the four minutes of editing, then close it and get back to the timer.

Putting each requirement next to actual proof before changing the resume is the right order. I'd be careful with the "four empty items, don't apply" rule, though: an advert can list four optional tools alongside one core skill a candidate demonstrates well. Would you split must-haves from nice-to-haves before counting gaps? Also, if the resume says "dashboards" but the candidate never used Power BI, swapping in "Power BI" for keyword match would turn a wording edit into a false claim.
Fair points, both of them. You are right that the four empty items test is too blunt as written. The version I use is to count gaps only against the lines under requirements, and to treat a short nice-to-have list as zero. On Power BI, I did not mean swapping in a tool you never used. That edit is only for words describing work you really did. If you never used it, the item stays empty, and the honest move is to leave it out or spend the week learning it.
