How to use AI in marketing without losing the human voice.

Does Google penalise AI-generated content?

No, not for being AI-generated. In its guidance on AI content, Google says its ranking systems "aim to reward original, high-quality content that demonstrates qualities of what we call E-E-A-T: expertise, experience, authoritativeness, and trustworthiness", and that its focus is on the quality of content, "rather than how content is produced". As Google puts it: "Using AI doesn't give content any special gains. It's just content."

The line Google draws is purpose. "Using automation, including AI, to generate content with the primary purpose of manipulating ranking in search results is a violation of our spam policies." Google also suggests thinking about who created the content, how, and why.

For a brand, that means AI is a tool, not a shortcut. A hundred generic pages produced to rank will not help you. One page that shows real experience, whoever typed the first draft, can.

How many businesses are using AI, and for what?

Adoption is growing fast. According to Eurostat, 20.0% of EU enterprises with 10 or more employees used AI technologies in 2025, up from 13.5% in 2024. The most common uses were analysing written language (11.8% of enterprises), generating visual and audio content (9.5%) and generating text or speech (8.8%).

In other words, the tools most relevant to marketing, writing and visuals, are already among the most used.

Why does the human voice still matter?

Because people care where content comes from.

• They want to know. In Getty Images' Building Trust in the Age of AI report, based on over 30,000 adults in 25 countries, almost 90% of consumers said they want to know whether an image has been created using AI, and 98% agreed that authentic images and videos are pivotal in establishing trust.
• They judge it differently. In an experiment by NIM, German participants saw identical ads for six products, labelled either "AI-generated" or "human-generated". The ads labelled as AI were rated less natural and less useful, attitudes towards them were more negative, and willingness to research or buy the product fell. AI labels were better accepted for innovative, high-tech products than for traditional ones.

That last finding matters for hotels, restaurants and local brands, whose appeal is built on place, people and craft. The more your brand depends on feeling real, the more careful you need to be about content that feels generic.

Where should AI help, and where should people lead?

A simple way to split the work:

How do you keep your brand voice when you use AI?

1. Write your voice down. Three to five traits, each with an example of how you would say something and how you never would. This is what you give an AI tool, and what you check its output against.
2. Give it your facts, not just a topic. Real details, names, dishes, rooms, stories. Without them, AI fills the gaps with generic phrases or with details that aren't true.
3. Edit for specifics. Replace every line that could describe any business ("hidden gem", "unforgettable experience") with one that could only describe yours.
4. Check every fact and number. AI tools can state wrong information with complete confidence.
5. Read it out loud. If it doesn't sound like someone on your team, rewrite it.
6. Keep a human sign-off. Someone who knows the business approves every piece before it goes out.

When do you have to label AI-generated content?

• In the EU, for realistic images, audio and video. Article 50 of the EU AI Act has applied since 2 August 2026. If you use AI to generate or manipulate image, audio or video content that constitutes a "deep fake", content that resembles real people, places or events and could pass as authentic, you must disclose that it is artificially generated or manipulated. According to the European Commission, the disclosure must come "upon first exposure at the latest" and be "clear and distinguishable". Evidently artistic, creative, satirical or fictional works have lighter requirements.
• In the EU, for some text. AI-generated text published to inform the public on matters of public interest must be labelled, unless it has gone through genuine human review or editorial control. The Commission specifies that superficial checks, such as spell-checking, don't count.
• On TikTok. TikTok's Community Guidelines require you to label content that uses AI or includes significant edits to show realistic-looking people or scenes.

Even where a label isn't required, the Getty data suggests most people would rather know.
