> TL;DR: Facebook Marketplace ads run through Meta Ads Manager, not Marketplace seller tools. You need a square image at minimum 1080x1080px, a 40-character headline, and at least one feed placement ticked alongside Marketplace. Coinis Image Ads generates Marketplace-ready creatives directly from a product URL.

Why Facebook Marketplace Ads Work
Marketplace puts your ad in front of people who are already shopping. That's a different audience from a scrolling News Feed.
Reach buyers with purchase intent
Marketplace users browse with intent to buy. Your ad appears among organic listings. Less convincing needed, faster path to conversion.
Affordable starting costs ($1/day minimum)
You can test a Marketplace campaign for approximately $1 per day. Validate your creative before committing a bigger budget.

Step-by-Step: Create Your First Marketplace Ad
Eight steps. Follow them in order.
Step 1: Choose your campaign objective
Click "Create" in Ads Manager. Pick an objective aligned with your goal. Sales, Traffic, and Leads all work well for Marketplace.
Step 2: Set budget and audience targeting
Set a daily or lifetime budget. Define your audience by location, age, and interests. Narrower targeting drives stronger relevance.
Step 3: Select Marketplace in placements (+ one feed placement required)
Under Placements, choose "Manual Placements" and tick Facebook Marketplace. Keep at least one feed placement ticked alongside it. Without a feed placement, certain objectives won't deliver ads at all.
Step 4: Create or source your ad image (1080x1080px square, high quality)
Your image must be square. Per Meta's Ads Guide, the minimum resolution is 1080x1080 pixels at a 1:1 ratio. There is no maximum resolution. Use the highest quality file you have.
Step 5: Write compelling headline, description, and CTA
Per Meta's Ads Guide, character limits are strict. 40 for headline, 30 for description, and 125 for primary text. Lead with price in the headline. Direct copy outperforms clever copy here.
Step 6: Preview your ad across mobile/desktop
Use the preview tool inside Ads Manager. Check your ad in Marketplace feed, News Feed, and mobile views before publishing.
Step 7: Set conversion tracking with Facebook Pixel
Install the Facebook Pixel on your site and connect it to your ad set. It tells Meta which users convert, which powers smarter optimization over time.
Step 8: Review and publish
Check budget, placements, and creative one final time. Then click Publish.

Image Specifications & Design Tips
Wrong specs get your ad rejected or looking blurry. Get these right from the start.
Minimum resolution: 1080x1080 pixels (square, 1:1 ratio)
Per Meta's Ads Guide, 1080x1080px is the floor. Use the highest resolution available. No maximum resolution limit applies.
File type: JPG or PNG, max 30MB
Per Meta's Ads Guide, accepted file types are JPG and PNG. Maximum file size is 30MB.
Best practices: High-contrast product shots, price-first headline, thumb-stopping visuals
Your ad competes directly with organic listings. High-contrast product shots on clean backgrounds stand out. Put your price in the headline. Give shoppers a reason to click before they read anything else.

Frequently Asked Questions
Can I run a Facebook Marketplace ad without a Facebook Business Page?
No. You need a Facebook Business Account with a connected Page to access Meta Ads Manager and run Marketplace ads. Marketplace seller tools do not support full ad campaigns.
What is the difference between a Marketplace ad and a boosted listing?
A boosted listing is a simple seller promotion with limited targeting options. A Marketplace ad runs through Meta Ads Manager and gives you full audience targeting, campaign objectives, conversion tracking, and placement controls.
