Machine translation post-editing, usually shortened to MTPE, is the practice of having a person correct text that a machine has translated, to an agreed standard. A light edit fixes errors that change the meaning and leaves the style alone. A full edit makes the text read naturally and correctly. Both work well for content that exists to be understood. For marketing copy, editing machine output is often the slower and weaker route: what the copy needs is rewriting from a brief.
This article explains MTPE for marketing and brand leads at hotels, resorts, attractions and travel brands: the two levels, when the effort is worth it, and why copy that sells an experience needs a writer.
Key Takeaways
- MTPE means a person correcting machine-translated text. Light post-editing makes it accurate and understandable; full post-editing makes it accurate, consistent and natural to read.
- Post-editing is worth the effort for operational, high-volume and short-lived content, where the goal is clear, correct information.
- Marketing copy usually needs rewriting, not editing. An editor corrects what the machine wrote; a writer decides what the message should be in that market, and a machine draft tends to anchor the result to the English.
What is machine translation post-editing?
MTPE is a two-stage process: a machine produces the translation, then a person checks and corrects it. The person, often called a machine translation post-editor, compares the output with the source text and fixes what is wrong. How much they fix depends on the level agreed before the work starts.
It became common because correcting machine output can be faster than translating from scratch, for the right kind of text. That qualifier is where most of the decisions sit.
Light vs full post-editing
The difference is the finish line. Light post-editing aims for text that is correct enough to understand. Full post-editing aims for text that a reader would not notice was machine-made.
| Light post-editing | Full post-editing | |
|---|---|---|
| Goal | Accurate and understandable | Accurate, consistent and natural to read |
| What gets fixed | Mistranslations, omissions, additions, wrong numbers or names, anything that changes the meaning | All of that, plus grammar, terminology, word order, style and flow |
| What is left alone | Awkward but correct phrasing, repetition, flat style | Little, apart from the structure of the source text |
| Typical use | Internal documents, gist of incoming messages, short-lived updates | Published factual content: FAQs, policies, practical information |
| What it does not do | Make the text sound good | Rethink the message for the market |
The last row matters most for a marketing team. Even a thorough full edit works inside the sentence the machine produced. It improves that sentence. It does not ask whether the sentence should exist, what should come first for this reader, or what the line should become to land the same way it does in English.
Is post-editing worth the effort?
For informational content, often yes. For persuasive content, often no. Post-editing pays off when three things are true: the machine output is reasonably good to begin with, the text is mainly factual, and the goal is correctness rather than effect.
That describes a lot of hospitality content: facility hours, transport directions, house rules for a serviced residence, operational notices and FAQs. Post-editing there saves time without lowering the standard that matters, which is clarity.
It stops paying off when the editor spends most of their time rewriting, which is what happens on brand copy: the sentence is correct but flat, so the editor rewrites half of it while fighting the English structure. At that point you are paying for writing, with a machine draft getting in the way.
Post-editing improves the sentence the machine wrote. Marketing copy usually needs a different sentence.
Why marketing copy needs rewriting, not editing
Marketing copy is built from choices, and a machine draft makes those choices for you before anyone has thought about the reader. Take a typical resort description in English: a hook about escaping the city, a sentence on the view, a line about the spa, a closing invitation to book. A machine renders each sentence faithfully, in the same order, with the same emphasis.
A writer working for, say, families from a particular Asian market might lead with something else entirely: the kids’ club, the connecting rooms, the dining options, the ease of getting there. The escape-the-city hook might not resonate at all. None of that is an error an editor would correct, because nothing in the machine draft is wrong. It is simply written for a different reader.
The same goes for wordplay and brand voice. A tagline built on sound or double meaning has to be re-created. A warm, playful voice comes out neutral, and turning neutral text playful is writing, not editing. That is the work transcreation is for. IPPWORLD describes the goal as bringing out the “visual imagery” in the reader’s mind: words that let readers picture what they are reading.
Signs a text needs rewriting rather than post-editing
- It sells an experience: hero copy, room and destination narrative, menus, campaigns, loyalty messages.
- It relies on tone, humour, wordplay or a slogan.
- The target market needs different information first, or a different level of formality.
- Readers in that market say it is correct but “sounds translated”.
- The editor is changing more than a few words per sentence.

What a good machine translation post-editor does
A good post-editor is a careful linguist who knows when to stop editing and say the text needs rewriting. They compare every segment with the source, check names, numbers and terms against an approved glossary, and flag anything that creates an obligation, such as prices, conditions and safety information.
For brand content the skill is different: someone who writes in the target language, understands the market and has a brief, with an editorial step after.
How IPPWORLD approaches marketing copy
We start from the brief and the market, not from a draft. At IPPWORLD, we are an award-winning transcreation agency that specialises in creative translation and marketing localisation for the hospitality, travel, lifestyle and retail sectors, named Best Hospitality Creative Translation & Localisation Agency 2019 at the LUXlife Hospitality Awards.
IPPWORLD defines transcreation as creative translation: a process that adapts the emotional expressions and contextual relevance of the source message, beyond the literal meaning of words. Our six steps are Understand the Project Brief, Pre-Transcreation Study, Transcreation, Client Review, Update and Approval, and Final Delivery. The client review puts creative decisions in front of your team before anything is approved, and a dedicated Translation Memory for each client keeps those decisions for future work. Hilton International Asia Pacific, which chose IPPWORLD as its APAC partner for global learning and development materials, credits the accuracy of the work to the use of native translators.
Review is built into delivery, too. For Changi Airport Group, our language editorial team also reviewed and updated the client’s existing Chinese content and ran terminology consistency checks on it before publishing. For Millennium Hotels & Resorts, quality checks made sure every language version was error-free before the website went live. More on the craft is on our transcreation and marketing translation pages.
Conclusion
MTPE is a sensible process for the right content. Neither level turns a machine draft into copy that sells an experience, because the decisions that make marketing work happen before the first sentence is written.
Use post-editing for what is meant to be understood. Brief a writer for what is meant to make a guest choose you.
Next step
If your content has been machine-translated and edited, and it is accurate but still not landing with the guests it targets, an audit is the sensible first step. Our guide to when a translation audit is worth doing explains what it covers. Then get in touch with IPPWORLD to explore options.
Frequently Asked Questions
What is MTPE?
MTPE stands for machine translation post-editing: a machine translates the text, then a person checks it against the source and corrects it to an agreed level. Light post-editing fixes errors that affect meaning; full post-editing also fixes grammar, terminology and style so the text reads naturally.
Is machine translation post-editing worth the effort?
For factual, high-volume or short-lived content, such as FAQs, practical information and internal updates, it often is. For marketing copy it often is not, because the editor ends up rewriting most of the text while working around a structure inherited from the source language.
What is the difference between light and full post-editing?
Light post-editing aims for text that is accurate and understandable, and leaves awkward but correct phrasing alone. Full post-editing aims for text that is accurate, consistent and natural to read. Neither rethinks the message for the target market.
What does a machine translation post-editor do?
They compare machine output with the source, correct meaning errors, check names, numbers and terminology, and, for a full edit, improve grammar and flow. A good post-editor also flags when a text is not suitable for editing and needs rewriting instead.
Can post-editing work for hotel marketing copy?
It can make the copy correct, but rarely persuasive. Hero copy, room and destination narrative, menus, campaigns and loyalty messages depend on choices about what to say first, what tone to take and what the reader should feel. Those are writing decisions, best made from a brief rather than by correcting a machine draft.
