The fifth article in the "Professional Use of Claude.ai" series is a guide for copywriters and content creators. We break down creating unique content, adapting tone and style, editing text, generating ideas, working with long-form materials, and localization. Each section relies on the prompt engineering principles from the second article of the series, and specifically on the few-shot technique, which works best here.
Why copywriting is the ideal niche for the few-shot approach
Of all the prompt engineering techniques covered in the second article of the series, the few-shot technique — providing examples of the desired style before the main task — is the most valuable for copywriting. Brand voice and stylistic nuances (tone of voice) are much easier to demonstrate visually than to describe with abstract words. Try explaining in text the difference between a "friendly but professional" and a simply "friendly" tone — the phrasing will inevitably turn out vague. However, two or three concrete examples of finished posts immediately eliminate this ambiguity.
Therefore, most effective prompt templates for working with text are built around the structure of "here are examples → write in a similar style," rather than long lists of adjectives.
Techniques for creating unique content
The primary mistake when generating content "from scratch" is using a query that is too broad, which results in technically correct but dry and lifeless output. The difference between a mediocre and a strong text is largely determined by the level of contextual detail regarding the target audience and the final goal of the material.
Prompt template: text generation
Role: You are a copywriter specializing in [niche: email marketing / social media / landing pages].Audience: [who is reading, their level of awareness, audience pain points].
Goal of the text: [sell, inform, evoke an emotion].
Style examples: [1-2 examples of previously written texts in the desired tone].
Task: Write a [content type] of [length/volume] about [topic].
The order of components matters here: first, the role and audience form the model's cognitive "frame," the style examples provide a clear benchmark, and only at the end is the actual task delivered. This perfectly aligns with the core principle: placing context before instructions yields a more accurate result.
Tone and style adaptation
The same information can be delivered in radically different ways depending on the communication channel and platform. The most practical approach is to write a single baseline (skeleton) version of the text with all the facts, and then ask the model to adapt it to various tones, rather than reinventing the wheel each time.
| Tone | When to use | Example phrase |
|---|---|---|
| Formal / Expert | B2B content, technical articles, press releases | "The study confirms the effectiveness of the implemented approach in 87% of cases." |
| Friendly / Conversational | Social media, community newsletters, blogs | "Honestly? We were a bit surprised by this result ourselves." |
| Provocative / Hook-driven | Headlines, ad creatives, lead magnets | "Most copywriters make this mistake every day. Check yourself." |
| Empathetic / Supportive | Health, finance categories, crisis communications | "We understand this is a difficult decision, so we have gathered all the facts." |
The prompt for this type of adaptation is short: "Here is the baseline text: [text]. Rewrite it in a [chosen tone], preserving all key facts and figures, but changing the delivery style." This ensures that critical information is not lost when changing the tone voicing.
Editing and improving texts
When editing an already finished text, a vague request like "make it better" is a path to random results. The model will begin swapping words around pointlessly. Defining precise optimization criteria acts much more effectively.
Specific queries for editing
"Reduce this text by 30%, strictly preserving all key arguments" • "Remove repetitions, tautologies, and heavy bureaucratic jargon from the text" • "Make the first sentence a stronger hook that instantly grabs the reader's attention" • "Check the logical sequence of arguments and flag weak transitions between paragraphs" • "Simplify all sentences longer than 20 words by splitting them into two"
For long-form materials, a two-step approach works beautifully: first, ask the model to identify and list the weak spots (without making changes to the text itself), evaluate this analysis, and only then issue the command to make corrections based on the approved points.
Generating creative ideas
For brainstorming headlines, content plan topics, or advertising campaign concepts, the most effective approach is to request a large number of options in a single run from different angles to prevent the model from getting stuck in a single pattern.
Prompt template: headline brainstorming
Generate 15 headline options for a [content type] about [topic]. Use different triggers: a direct question, an intriguing statistic, healthy skepticism, storytelling (personal story), and a mistake warning. After the list, briefly explain which emotion each approach targets.
Explaining the logic (why a specific option was generated) helps you filter raw ideas faster and choose a working concept.
Working with long-form content (longreads)
When creating high-volume materials (longreads, e-books, extensive guides), attempting to generate everything in one go almost always leads to a loss of depth and logical gaps within the text. The process should be broken down into iterations.
Prompt template: step-by-step longread workflow
Step 1: "Create a detailed, expanded outline for an article about [topic] for an audience of [who]. The structure must include an introduction-hook, 4-5 H2 sections with H3 subsections, and a conclusion with a clear CTA. Write the main thesis for each section."Step 2 (after approving or adjusting the outline): "Now write exclusively Section 1: [Section Name], following our outline. Tone: [style]. Target length: ~[number] words."
Step 3 (after writing all sections sequentially): "Here is the complete text of all sections. Read it through entirely and align the stylistics, sentence length, and terminology for absolute consistency of the author's voice."
This approach allows you to keep your finger on the pulse: if the model drifts off-course during Step 2, you can correct it with a single sentence before the rest of the massive text is generated.
Translation and localization
For translating marketing materials, Claude demonstrates excellent results precisely because it understands context and subtext, unlike traditional machine translation which often translates idioms literally.
If you just need to translate clean text (for example, a social media post or an ad creative), the basic approach looks like this:
Prompt template: meaning localization
Here is a text in [source language]: [text].Adapt it for an audience from [target country/culture], fully preserving the emotional impact and original tone. Be sure to replace specific idioms, metaphors, or cultural references with appropriate local equivalents that sound natural to native speakers.
The word adapt in the prompt acts as a trigger for the model — it grants permission to step away from literal word copying to preserve the initial meaning and emotion. The model doesn't just translate words; it searches for matching cultural codes.
Localizing ready code: how not to break your website
However, the task becomes drastically more complicated if your website or blog runs on a static site generator (Eleventy, Hugo) or is managed through a Headless CMS (Decap CMS). In this case, an article is not just text, but a complex engineering construct containing YAML front matter, inline styles, tags, and service attributes.
A conventional AI translator attempting to translate such a file will create chaos: it might accidentally translate system keys (for instance, replacing date with дата), wipe out unique URL slugs, or break CSS classes.
To localize an article along with its layout, you need to use a hybrid prompt. It simultaneously protects the code architecture and allows complete freedom for linguistic adaptation:
Professional prompt for technical article localization
Role & Task: You are an expert technical writer and native English content localizer. Your task is to adapt the technical article provided from Ukrainian for a global, English-speaking IT community.
1. Technical Integrity (Critical):
- YAML Front Matter: Keep the exact structure intact. Translate ONLY the values of keys like 'title', 'description', 'ai_summary', and 'faq'. Do NOT touch the system keys themselves (
date,permalink,tags, etc.).- Permalink Strategy: Prepend the
permalinkvalue with/en/, but keep the rest of the URL slug exactly as it is to prevent routing issues.- HTML/CSS Code: Do not modify any HTML tags, CSS classes (
class="rec-box"), or content inside<style>blocks. Translate only the values insidedata-label="..."responsive table attributes.2. Tone & Vocabulary:
- Avoid literal word-for-word translation. Use Active Voice. Map key terminology correctly: "контекстне вікно" -> "context window", "адаптація тону" -> "tone voicing/adaptation".
Practical breakdown: how it works in reality
An experiment with localizing the complex technical materials of our blog using this prompt showed three important results:
-
Targeted metadata translation: Claude clearly understood the difference between code and content. It left classes like
class="rec-box"untouched, but translated hiddendata-label="..."attributes that ensure the correct rendering of tables on smartphone screens. - Natural IT terminology: The model rejected literal translation. Expressions like "quality of written speech" became native "natural language generation quality", and "audience pains" turned into standard industry terms like "audience pain points".
-
Mirrored i18n structure: Thanks to the precise instructions regarding permalinks, the model automatically prepended the
/en/prefix to the original slugs. This allows deploying localized versions of pages without manual redirect configuration or modifying config files.
Author's advice: Always specify in the Constraints block which elements the AI is forbidden to touch. Structural safety is the first thing to secure before giving the model creative freedom.
SEO optimization of texts during writing
Copywriting and SEO are inseparable today when content is prepared for blogs or informational websites. At the text generation level, Claude perfectly integrates specified keywords (LSI and core keywords) into the text so that they look organic, rather than artificially stuffed for search engine bots. To achieve this, simply add the list of "keys" into the prompt's constraints block with the instruction "distribute evenly throughout the text without direct over-optimization, and inflect according to grammar rules."
What's next?
The next article in the series shifts from working with words to working with numbers and logical relationships. We will explore how to configure Claude for analytical tasks, structuring datasets, generating reports, and high-quality data synthesis.
