ONLINE ADVERTISING WITH AI: COPY, VISUALS, TESTS

Meta, Google, Instagram: how AI helps write ten versions of an ad, produce the visuals, target and test without burning the budget. And the mistakes that cost.


By Arnaud Poirier, freelance web & software developer, Antibes
In brief
  • AI writes ten hooks and five texts in a few minutes; you keep the best three.
  • The platforms' machine-learning targeting beats your guesses if you give it conversions to observe.
  • Send to a fast, dedicated page, measure calls and sales, cut fast what does not work.

Online advertising rewards those who test a lot. AI makes tests almost free: ten hooks, five visuals, three audiences, in an hour instead of a week.

1. Write the ads

Give the assistant your offer, your typical customer and three reasons to buy. Ask for ten short hooks and five long texts, in a precise tone. Keep the best three, rewrite them in your own words. What works in advertising is precision (“wood-fired pizza, Golfe-Juan, takeaway in 15 minutes”), not poetry.

2. Produce the visuals

A real packshot on three generated backgrounds, a square format and a story format, readable text added afterwards. Platforms now prefer short videos: a photo animated in three seconds, generated by AI, is often enough to start.

3. Target

Platforms now do the targeting themselves by machine learning: give them a broad audience, a radius around your address, and let the algorithm find who responds. The platform's AI is better than your guesses, provided you give it enough conversions to observe.

4. Test, then cut

Three ads, a modest daily budget, one week. We cut the ones that do not convert, double the one that works, launch a new variant. It is mechanical, and that is what AI speeds up.

The mistakes that cost

  • Sending to a slow site or a generic home page. Every paid click deserves a dedicated page that loads in two seconds.
  • Letting AI promise : “the best”, “guaranteed”, “medical”. You are responsible for every word published.
  • Not measuring calls, bookings, sales. Without measurement, you pay for clicks.

What I do

The fast landing page, conversion measurement, and setting up the test method. The advertising itself, you can run yourself after a workshop, or hand to a specialist: I do not sell campaign management.
