Market Ads

Market Ads — Platform-Native Ad Copy

Write ads that follow each platform's character limits, creative norms, and policy rules. Ads that break limits get rejected; ads that fit platform conventions perform better.

Platform Character Limits (2024+)

Meta (Facebook / Instagram)

| Element | Limit | |---|---| | Primary text | 125 chars recommended (2,200 max, truncates) | | Headline | 27 chars recommended (40 max) | | Description | 27 chars recommended | | Link URL | Must be valid and match destination |

Google Search (Responsive Search Ads)

| Element | Limit | Count | |---|---|---| | Headline | 30 chars | 3–15 | | Description | 90 chars | 2–4 | | Final URL | — | 1+ | | Path (display URL) | 15 chars | 2 |

Sitelinks, callouts, structured snippets are separate extensions.

LinkedIn

| Element | Limit | |---|---| | Intro text | 150 chars recommended (600 max) | | Headline | 70 chars | | Description | 100 chars |

LinkedIn audiences read; headlines can be longer than Meta.

TikTok Ads

| Element | Limit | |---|---| | Ad text | 100 chars (no emoji in some regions) | | Display name | 40 chars | | Video | 5–60s, 9:16 vertical |

YouTube

| Element | Limit | |---|---| | Headline (in-stream) | 15 chars headline, 70 description | | Discovery ads | 25 char headline, 35 char descriptions (x2) |

Creative Frameworks

The Hook-Insight-Offer structure (Meta / TikTok)

• Hook (line 1): pattern interrupt, specific pain, or bold claim
• Insight (line 2): why this matters / the turn
• Offer (line 3): what to do next with a specific incentive

The Match-the-Intent structure (Google)

The ad must match the search query. If someone searches "crm for small business":

• Headline 1 includes "crm for small business"
• Headline 2 = differentiator
• Headline 3 = CTA or offer
• Description = proof + benefit

The B2B structure (LinkedIn)

• Intro: name the audience, name the outcome
• Headline: specific result
• Description: proof + CTA

Output Format (per platform)

## [Platform] Ad Set — [Product / Campaign]

**Audience:** [targeting notes]
**Offer:** [incentive]
**Landing page:** [url]

### Variant A — [Angle name]
- **Primary text / Intro:** "[copy]" (X/125 chars)
- **Headline:** "[copy]" (X/27 chars)
- **Description:** "[copy]" (X/27 chars)
- **Angle:** [what this variant is testing — pain, status, curiosity, social proof]

### Variant B — [Different angle]
...

### Variant C — [Different angle]
...

### Creative brief
- Visual: [describe — single image, carousel, UGC-style video, animated]
- Hook second: [first 3s of video or headline of static]
- CTA button: [Shop Now / Learn More / Sign Up / Download]

Always ship at least 3 variants per platform testing different angles. Ad platforms learn fastest when fed multiple creatives.

Testing Matrix

| Variable | Test | |---|---| | Audience | Broad vs lookalike vs interest vs retargeting | | Angle | Pain vs outcome vs identity vs status | | Hook type | Question vs claim vs story vs stat | | Creative | Static vs video vs UGC vs animated | | CTA button | Learn More vs Sign Up vs Get Offer |

Only test one variable at a time — changing creative and audience together gives you no learning.

Policy Checklist (review before shipping)

• [ ] No unsupported health / financial / dating claims
• [ ] No personal attributes ("are you depressed?") — Meta will reject
• [ ] No before/after photos (Meta health policy)
• [ ] No all-caps or excessive punctuation
• [ ] No "you" targeting implications ("Hey Single Moms in Dallas")
• [ ] Landing page matches ad claim
• [ ] Disclaimers on earnings / results claims
• [ ] Trademarked terms handled correctly (Google brand bidding rules)

If a claim is even slightly borderline, flag it explicitly in the output rather than shipping it and risking account suspension.

Pre-flight

1. Offer / product / price
2. Target audience
3. Platform(s)
4. Landing page URL
5. Any existing winning ads to preserve angles from
6. Brand voice (load BRAND-VOICE.md if present)

Quality Bar

• Count the characters. Never ship copy over the limit.
• Never copy the organic social copy into ads — they're different mediums.
• Never promise what the landing page doesn't deliver. Mismatch tanks Quality Score on Google and Relevance Score on Meta.
• Each variant must test a distinct angle — "Variant B: same message, different emoji" is useless.
