Building Digital Ads with Claude
Writing ads is one of those tasks that sounds quick but isn’t.
One campaign might need five headline variations, three different body copy angles, platform-specific versions for LinkedIn vs Facebook, and a handful of CTAs to test. By the time you’ve written all of that, briefed the designer, and gotten approvals — half a day is gone.
I do this for multiple clients. So I built a better way.
What is this tool exactly?
It’s a custom Claude workflow — a skill, in Claude Code terms — that takes a campaign brief and produces complete, ready-to-use ad copy across multiple platforms and formats.
I give it the context: who the client is, what we’re promoting, who the audience is, what the offer is, and what platform we’re running on. It gives me back structured ad copy that’s already formatted correctly for each placement.
What does it actually produce?
Depending on what I ask for:
- LinkedIn ads — intro text, headlines, descriptions, CTAs
- Facebook/Meta ads — primary text, headline, link description
- Display ads — short headline, long headline, descriptions at multiple character counts
- Multiple variations — different angles (problem-focused, outcome-focused, proof-focused) so we have options to test
Everything comes out on-brand because the tool already knows the client’s voice, positioning, and audience. That context lives in my second brain and gets loaded automatically when I call the skill.
Why did I build this instead of using a generic AI tool?
Generic AI tools write generic ads. They don’t know that one client speaks to procurement managers at manufacturing companies and another speaks to independent farmers making equipment decisions. Brand voice isn’t just tone — it’s knowing what problems actually matter to a specific audience.
When the client context is baked into the system, the output is actually usable. I’m not rewriting 80% of what it gives me. I’m making small edits and moving on.
How does it fit into the real workflow?
I use it at the brief stage. Once I know the campaign objective and the audience, I run the skill and use the output as the starting point for the creative brief I hand to the design team.
The designer gets structured copy with clear character counts and placement specs. I’m not rewriting the same CTA five different ways. Reviews are faster because the structure is already right.
The whole process went from something that took most of a morning to something that takes about twenty minutes.
Could you build something like this?
Yes. The key is not the AI — it’s the context you give it. A generic “write me an ad” prompt gives you generic output. A prompt that includes the client’s positioning, their audience’s specific pain points, the offer, and the platform specs gives you something actually worth using.
Build the context first. The tool becomes useful almost automatically.
