AI in Marketing

Marketing has arguably absorbed AI faster than any other field — and it's also where over-reliance shows up fastest, in content that all starts sounding the same.

Where AI is genuinely useful right now

Illustrative scenario: brands increasingly use AI to generate dozens of ad copy variants for A/B testing, letting real audience data — not guesswork — decide which message performs best.

Where to be careful

A useful test: if you'd be embarrassed to tell a customer a specific piece of content was written entirely by AI with no edits, it needs another pass before it goes out.
Getting started: Use AI for the first draft and the tedious variants, like A/B test copy or format adaptation, but keep a human editorial pass before anything ships — that's the difference between AI-assisted and AI-generic content.

A simple workflow marketing teams actually use

  1. Brief the AI tightly. Feed it your brand voice guide, target audience, and 2-3 examples of copy you like — vague prompts produce generic output.
  2. Generate 5-10 variants, not one. AI is cheap to iterate with; pick the best elements from several drafts rather than accepting the first result.
  3. Edit for specificity. Replace generic claims ("industry-leading", "cutting-edge") with real numbers, names, or details only your brand would know.
  4. Fact-check before publishing. AI can invent statistics or misattribute quotes — verify anything presented as fact.

Make AI earn its place through better experiments

Marketing teams can generate endless copy with AI; volume is not the same as value. I would use it to create genuinely different hypotheses, angles and first drafts, then judge them with real audience results rather than choosing whichever version sounds most polished.

A practical test: Pick one campaign and use AI to produce three distinct approaches based on the same brief. Human-edit them, run the normal test, and compare performance with the team’s baseline.

A prompt template to adapt

This is a template, not a tested result. Replace the brackets with your own details:

"Write three subject lines and one 80-word email for [audience] about [offer]. Use these verified facts only: [facts]. Keep the tone [tone], avoid exaggerated claims, and do not invent testimonials or statistics."

Frequently asked questions

Does using AI to write marketing copy hurt SEO?

Not inherently — search engines penalise low-quality, unedited mass content, not AI use itself. Reviewed, genuinely useful AI-assisted content performs fine.

Do I need to disclose AI-generated ad content?

For certain content, like AI-generated testimonials or influencer posts, yes, under FTC (US) and ASA (UK) rules. Check the specific disclosure requirements for your content type and region.

Which marketing tasks should stay human-only?

Brand strategy, tone-of-voice decisions, and anything involving real customer relationships or sensitive judgment calls — AI can support these but shouldn't lead them.
