Writing Year-End Campaign Copy with AI: 5 Rules for Staying True to Your Brand

With the November sales season (Black Friday, 11.11) around the corner, you need a lot of short texts for ads, emails and social media. AI really does save time here. But if you simply ask it to 'write a sale text', it hands you something anyone could have written and no brand owns. These five rules help you get a fast draft without losing your voice. The post suggests one shared working order for ads, email and social media: voice first, then examples, then checks. If you keep that order, AI gives you speed and you give your brand its trustworthiness.

1. Describe your brand's voice first

AI does not know you. If you do not explain who you are and how you talk to customers, it falls back on generic ad language. Prepare a short 'voice guide': warm or formal, which form of address you use, which words you never use. Write it once and paste it at the top of every request. A jeweler might describe a trustworthy, plain voice that stresses craftsmanship, while a children's clothing shop might pick something cheerful and parent-friendly. The same cold sale text suits neither. Also list the phrases you never use in campaigns; once AI knows that, you will not need to correct it again and again. Update the voice guide with a quick review at month end or after each campaign.

2. Feed it examples you already like

Describing a voice in words is not enough; showing examples works far better. Add a handful of past texts that performed well or that feel like 'us'. Do not include messages containing customer details, phone numbers or order numbers; use only published, public-facing copy. Good examples show by themselves how long or short a business writes, whether it uses emoji, how it addresses customers and in what tone it says thank you. After sharing them, ask the AI to summarize the style in its own words first; if it misread you, you fix that before any copy is written.

3. A human must check every price, date and condition

AI writes fluently, but it does not write for accuracy. It can change or invent a discount rate, an end date or a 'limited stock' line on its own. Supply these details yourself in the request and compare each one against your source in the output. A wrongly printed price costs more than the time it saved. Keep checking after launch too: if you spot a mistake on day one, update every channel right away. It helps to have the person who wrote the copy differ from the person who checks the price list, since a second pair of eyes catches more. A campaign's success often depends less on how polished the text is and more on whether what it promises turns out to be true.

4. Stay away from exaggeration and misleading claims

AI loves excitement: 'cheapest', 'unmissable deal', 'on everything'. Commercial ads must be truthful, and a discount must not look bigger than it really is; in Turkey the Ministry of Trade's advertising rules and the Advertising Board oversee this. The rules get updated from time to time, so check the current text before big campaigns. This is not legal advice; if you are unsure about a claim, take it out. Sweeping phrases such as 'on all products' or 'lowest price' mislead customers when there are exceptions, and later turn into complaints. Stating the conditions in a small but readable note is honest and good for business too.

5. Do not copy the same text to every channel

An ad headline must be short and clear, an email can explain more, an Instagram caption can feel warmer. Pasting the same text everywhere is easy but tiring for the reader. Ask AI for a separate version per channel and check each against that channel's length limits. On social media a story visual needs just a few words, while an email can spend a few sentences on who the offer is for, why, and until when. Each channel's reader is also in a different mood at that moment. Finally, read the output aloud before publishing: if a sentence would never come out of your own mouth, it should not come out of your brand's either. This simple test usually exposes machine-sounding phrasing right away.

Three request patterns you can copy and adapt

• Voice guide pattern: 'Follow this brand voice guide: [warm, plain, polite you-form, no hype]. Write 3 short email subject lines for this product. Do not add prices or dates, I will add them myself.'
• Example-based pattern: 'Here are three past texts I like from my brand: [text 1, 2, 3]. Keep this style and suggest 2 social captions for [the November sale]. Do not make up anything you do not know; leave it blank.'
• Channel adaptation pattern: 'Turn the campaign details below into a headline of up to 30 characters, then a 60-word email, then a two-sentence Instagram caption. Details: [product, discount, end date].'
