Ad Copy Writer

Generate high-converting ad copy for Google, Microsoft, Meta, LinkedIn, TikTok, Reddit, Snapchat or X Ads. Works with no accounts connected.

Usage

`/ad-copy-writer google "project management tool"` — Google Ads copy `/ad-copy-writer meta example.com` — Meta Ads copy from website `/ad-copy-writer linkedin "B2B SaaS"` — LinkedIn Ads copy `/ad-copy-writer reddit|tiktok|snapchat|x|microsoft example.com` — other platforms

Works with

| Job | Primary | Also answers it | What differs | |-----|---------|-----------------|--------------| | Product and competitor research | WebFetch / WebSearch | — | Always available | | Angles already running (enhanced when connected) | The target platform's ad MCP | Any other connected ad platform | Read-only; used to avoid repeating angles, never to edit ads |

Pulling live ads per platform (tool names omit `mcp__cogny__mcp__<Prefix>__`):

| Platform | Prefix | Read current copy | |----------|--------|-------------------| | Google | `Google_Ads` | `tool_execute_gaql(customer_id, query: "SELECT ad_group_ad.ad.responsive_search_ad.headlines, ad_group_ad.ad.responsive_search_ad.descriptions, metrics.ctr FROM ad_group_ad WHERE ad_group_ad.status = 'ENABLED' AND segments.date DURING LAST_30_DAYS")` | | Microsoft | `Bing_Ads` | `tool_get_ad_groups` → `tool_get_ads(account_id, ad_group_id)` | | Meta | `Meta_Ads` | `tool_get_ads(ad_account_id, status_filter: ["ACTIVE"], include_creative: true)` | | LinkedIn | `LinkedIn_Ads` | `tool_get_creatives(ad_account_id, status_filter: ["ACTIVE"])` | | TikTok | `TikTok_Ads` | `tool_get_ads(advertiser_id, status_filter: [...])` | | Reddit | `Reddit_Ads` | `tool_get_ads(ad_account_id)` | | Snapchat | `Snapchat_Ads` | `tool_list_organizations` → `tool_list_ad_accounts` → `tool_get_creatives(ad_account_id)` | | X | `X_Ads` | `tool_get_tweets(account_id, tweet_type: "PUBLISHED")`, `tool_get_cards(account_id)` for card headlines | | Apple Search Ads | `Apple_Search_Ads` | `tool_list_acls` → `tool_get_campaigns` → `tool_get_ad_groups` → `tool_get_targeting_keywords` (keywords, not copy) |

Steps

1. Research the product

If a URL is provided, WebFetch it and extract:

• Value proposition
• Key features / benefits
• Target audience
• Pricing (if visible)
• Unique differentiators

If a description is provided, use that directly.

2. Research the competition

WebSearch for competitors to understand:

• What messaging angles they use
• Common claims in the space
• Price anchoring

2b. Enhanced when connected: read what's already running

If the target platform is connected (check `mcp__cogny__list_integrations`), pull its active ads with the tool above. List the angles, claims and CTAs already in use, and mark the top performers by the platform's own CTR where available. Then write new copy that tests *different* angles, and say which existing angle each new variation is meant to beat. If nothing is connected, skip this step.

3. Generate copy by platform

Google Ads (RSA format)

Generate 15 headlines (max 30 chars each) and 4 descriptions (max 90 chars each):

**Headlines** — mix of:

• Benefit-led: "Cut Ad Spend 40%"
• Feature-led: "AI-Powered Optimization"
• Social proof: "Trusted by 1,000+ Agencies"
• CTA: "Start Free Trial Today"
• Keyword-match: "[Primary keyword] Tool"

**Descriptions** — mix of:

• Problem/solution
• Feature list
• Social proof + CTA
• Urgency/offer

Meta Ads

Generate 3 variations:

• **Primary text** (50-150 chars recommended for single-image Feed ads, per Meta's Ads Guide; up to 500)
• **Headline** (27 chars recommended for single-image Feed ads; longer headlines truncate)
• **Description** (30 chars)
• **CTA button** recommendation

Angles: 1. Pain point → solution 2. Social proof → aspiration 3. Direct value prop → CTA

LinkedIn Ads

Generate 3 variations:

• **Intro text** (150 chars recommended to avoid truncation; 3,000 max)
• **Headline** (70 chars recommended; 200 max)
• **Description** (100 chars recommended; 300 max; shown only on LinkedIn Audience Network placements)

Angles: 1. Professional credibility 2. ROI / efficiency focus 3. Industry-specific insight

Microsoft Ads (RSA format)

Same limits as Google: 15 headlines (30 chars), 4 descriptions
