How to Write a Paid Ad (and How Not To)

Most ads read like a product brief that escaped a meeting and wandered onto the internet.

By Cynical SallyIssue Nº 1

You have roughly 1.7 seconds before a thumb flicks you into oblivion. That is your whole career as an ad. Not a paragraph, not a brand story, not your 'why'. A second and a half. Most ads spend it clearing their throat.

The Full Truth

on A DTC skincare brand's Facebook ad

4.1
out of ten
You wrote 'glow' three times and never once said what the product actually does. That is not a tagline, that is a candle scent pretending to be a face cream.
The Investigation
  1. 01

    The headline introduces a product nobody asked to meet

    Critical

    'Introducing GlowDrops: Your Skin's New Best Friend' spends all seven words on you and zero on the reader. Nobody scrolls Facebook hoping to be introduced to a serum. Lead with the result they already want: 'Tight, flaky skin by 3pm? This fixes it by Friday.' The product name belongs in the second line, after you have earned a reason to keep reading.

  2. 02

    Adjective soup where a benefit should be

    Critical

    'Clean, vegan, dermatologist-formulated, plant-powered radiance' is four claims that say nothing a buyer can feel. 'Vegan' is table stakes, not a hook. Pick the single most concrete promise (does it stop the 4pm dry patch, fade redness in two weeks, survive a humid commute?) and let the certifications live in the comments or the landing page where they belong.

  3. 03

    The call-to-action evaporates on contact

    Notable

    'Discover your glow today' is not an instruction, it is a horoscope. The reader does not know what happens after the click: a quiz, a product page, a discount, a void? Tell them the literal next step. 'See the before-and-afters' or 'Take the 30-second skin quiz' sets an expectation and lifts click-through because the brain likes knowing where the door leads.

The Action Plan
  1. 1Rewrite the first line to name one specific problem the buyer feels, and cut every word before that problem appears.
  2. 2Replace the adjective stack with a single measurable benefit and one proof point (a number, a timeframe, or a before-and-after).
  3. 3Swap the vague CTA for the literal next action, then run it as a head-to-head against the old one on identical budget.
  4. 4Strip the offer to one promise per ad, kill the permanent '50% OFF', and let the winning variant earn the scale-up budget.

Your turn

That was a stranger's ad copy. Drop yours, I will go just as hard.

One coffee, from €2,99. No mercy.

The good news: paid ads are the most honest medium there is. Nobody asked to see you, nobody is being polite, and the metrics do not lie. If your ad is boring, the cost-per-click will tell you in a voice colder than mine. Let's make yours worth the slot it stole.

How to do it right
  • 01Lead with the one specific outcome the reader wants, in the first five words, before the scroll eats you.
  • 02Name the exact problem, not the category. 'Tightness after washing' beats 'skincare concerns' every time.
  • 03Use one idea per ad. Test it against another single idea. One ad, one promise, one click.
  • 04Write the call-to-action as the next physical step, not a vibe. 'See the 3-step routine' over 'Discover more'.
  • 05Make the first line survive without the image. If the photo fails to load and your ad dies, the photo was doing all the work.
How not to
  • Opening with 'Introducing' or 'Meet', as if the reader requested a formal product debut.
  • Stacking five adjectives ('clean, vegan, cruelty-free, dermatologist-loved, glow-boosting') and zero reasons to care.
  • Burying the offer under a brand origin story about a founder's kitchen and a dream.
  • Using 'Discover', 'Elevate', 'Unlock', and 'Transform' in one ad like a buzzword bingo card.
  • Slapping '50% OFF' on everything so the discount means nothing and the urgency reads as desperation.
