A consistent idea for the feed
LinkedIn ad creative,
kept together.
Make the same product, offer or business story work in two compositions. Choose LinkedIn ad kit when you create Fast Ads and every concept arrives with both formats and copy. You can also adapt a saved Fast Ad. The artwork and copy stay together on the main or locked canvas.
- 01 / Square creative
- A 1:1 image you can use across the desktop and mobile feed.
- 02 / Portrait creative
- A 4:5 composition for mobile feed delivery, preserving the direction of your original.
- 03 / Campaign Manager copy
- A headline, introductory text and suggested call to action, alongside the short message on the image.
The kit prepares your creative. You control the audience, destination, budget and launch in LinkedIn.

Creative and campaign setup
An ad kit for
your LinkedIn ad set.
LinkedIn uses campaigns, ad sets and ads. An ad set is where you choose delivery settings such as audience, format and placements. The Ad Legends kit gives you artwork and copy to use in your ads; it does not create or configure the ad set.
For the delivery side, follow LinkedIn’s Campaign Manager setup guide. You remain in control of campaign settings and media spend.
This first LinkedIn kit focuses on still-image Sponsored Content. Organic posts, video, carousels, document ads and Thought Leader Ads are separate formats. Test your finished ads against your own campaign goals.
Before you make one
LinkedIn ad kit questions.
What is a LinkedIn ad kit?
A LinkedIn ad kit brings together square and portrait single-image Sponsored Content creative, with headline, introductory text and a suggested call to action. Choose LinkedIn ad kit when starting Fast Ads to receive three concepts, each in both formats with copy, or make a kit from an existing ad. Each kit stays in an expandable drawer beside its original.
Is a LinkedIn ad kit the same as a LinkedIn ad set?
No. LinkedIn Campaign Manager organizes campaigns into ad sets and ads. Ad sets control settings such as audience, ad format and placements, with budget and schedule depending on the campaign setup. An Ad Legends kit supplies artwork and copy for your ads. It does not create or configure a LinkedIn ad set.
Which LinkedIn ad sizes does the kit generate?
The kit generates a 1200×1200 square image (1:1) for desktop and mobile, and a 1200×1500 portrait image (4:5) for mobile. Each exported image is no larger than 5 MB. These are the two formats in this kit, not every format LinkedIn supports. Review the current LinkedIn specifications and placement preview before publishing.
Can I use an existing Fast Ad to make LinkedIn ads?
Yes. Open the existing session, choose your original ad, expand Generate ad kits and select LinkedIn. Choose Make LinkedIn ad kit to create the missing formats and Campaign Manager copy. Your original remains available, and existing LinkedIn kit formats are reused.
Does this LinkedIn ad generator write copy too?
Yes. The kit includes a headline, introductory text and a suggested call to action alongside the short message on the artwork. Review the Campaign Manager copy details in the drawer, then copy the fields into LinkedIn. Confirm text truncation, destination and available CTA for your selected placement.
How much does a LinkedIn ad kit cost?
Choose LinkedIn ad kit before generation and both formats with copy are included in the displayed Fast Ads cast price, just like Meta. More like this also includes both formats when a LinkedIn kit is requested. Making a kit from an existing ad is a separate action: 2 Legend Credits per missing format, or 4 when both are new; saved formats in that kit are reused. LinkedIn media spend is separate.
How long does generation take, and can I leave the page?
For a kit made from an existing ad, allow around one to two minutes; some kits take longer. Creating new concepts and their kits can take several minutes. Loading cards show progress, with an elapsed timer for existing-ad kit generation. Keep the page open until your results appear. You can switch browser tabs while it runs, but avoid refreshing or leaving the page.
Can my AI agent create a LinkedIn ad kit?
Yes. Connect your AI agent to Ad Legends through MCP and ask for LinkedIn ad kits when creating Fast Ads or requesting More like this. It can also make a kit from an existing Fast Ad. Your agent can read the saved artwork, platform copy and generation outcome from the session. Keep connected generation requests open while they run.
Does the kit create organic posts, video ads or launch a campaign?
This kit creates still-image Sponsored Content artwork and copy. Organic posts, video, carousels, document ads and Thought Leader Ads are outside this kit. Download each image and upload it with the copy in Campaign Manager. You choose targeting, budget and launch settings; the kit does not publish paid ads or guarantee performance.
