A recruiter reading your CV is holding it against a list — the requirements in the job description. If the words on the list are not on your CV, you do not match, however good you are. Tailoring is the work of making that match visible. Done properly it takes about twenty minutes per application, and it changes the response rate more than anything else you can do.
Step one: read the advertisement like a checklist (5 minutes)
Print it or paste it into a document. Highlight every concrete requirement: skills, tools, qualifications, years of experience, types of work. Ignore the fluff about culture and passion. What you are left with is the checklist the recruiter or the screening software is using.
Then mark each item: have it, partly, or don't. Be honest. A CV that claims everything is less credible than one that claims most things clearly.
Step two: match the language (5 minutes)
For every item you marked "have it", find where it appears on your CV and make sure it uses the same words the advertisement uses. If the ad says "financial reporting" and your CV says "accounts preparation", change yours. If it says "stakeholder management" and you wrote "worked with clients and internal teams", add the phrase.
This is not gaming the system. It is translation. Different companies call the same work by different names, and screening software cannot tell that they are the same.
Put the two or three most important matches into your profile paragraph at the top, where they will be seen first.
Step three: reorder, do not rewrite (5 minutes)
Within each job on your CV, move the bullet points that match this role to the top. A logistics role does not care that you also handled the social media account; a marketing role does. The same job history, different emphasis.
The same applies to your skills list: lead with the ones the advertisement asks for.
Do not delete experience to make the CV look more focused than your career was. Gaps and missing roles raise more questions than a bullet point that is not perfectly relevant.
Step four: handle the gaps honestly (3 minutes)
For items you marked "partly", find the closest real evidence. If they want Power BI and you have Excel dashboards, say "built management dashboards in Excel; currently learning Power BI" — true, and it shows the direction.
For items you marked "don't", leave them out. Do not add a skill because the job wants it. The interview will find out, and most recruiters would rather see nine honest matches than ten claimed ones.
Step five: the cover letter and the file name (2 minutes)
If a cover letter is expected, its first paragraph should name the role and the company and give one reason that connects your strongest match to what they need. Do not restate the CV.
Name the file Firstname-Lastname-CV-Company.pdf. It sounds trivial; a recruiter downloading forty files called CV.pdf notices.
What not to change
Your job titles, employers and dates stay exactly as they are on every version. Changing a title to sound closer to the role is where tailoring turns into misrepresentation, and reference checks catch it.
Keeping the versions straight
After ten applications you will have ten slightly different CVs, and you need to know which one went where — because if they call, you should be looking at the version they have. Keep them named clearly, or use the CV version manager on this site, which stores each one with a label and shows the differences between any two.
The tools that do the reading for you
The CV and job ad matcher on this site does step one and two mechanically: paste the advertisement and your CV, and it lists which of the advertisement's key terms appear in your CV and which are missing. It cannot judge whether you actually have the skill — that part stays with you — but it saves the highlighting.
