Conversation Ads

Conversation ads are a LinkedIn Sponsored Messaging format. They land in a member's LinkedIn inbox as a message from a named sender, and instead of one button they offer several. Each button can lead to another message, a landing page, or a Lead Gen Form, so the ad behaves like a short scripted chat. LinkedIn's specifications allow up to five CTA buttons per message and 50 per conversation, an intro message of up to 8,000 characters with up to 10 emojis, and a subject line of 60 characters. You build the tree in Campaign Manager, and reporting shows which buttons people pressed, so you can see which branch of your message earns attention. Because the whole ad lives in the inbox, the quality of the first two lines decides almost everything.

Delivery has its own rules. LinkedIn's placement page says Sponsored Messaging appears in LinkedIn Messaging on desktop and mobile, and only to members who are logged in. For targeted members, the messages move to the Archived Messages folder after 60 days. The sender is a real profile that you choose or add, and a Business Manager admin may need to approve it. The optional 300 by 250 pixel banner shows only on desktop. In the EEA and Switzerland, LinkedIn says targeting is supported only for members who opted in to see Sponsored Messaging ads in their inbox, which can shrink audiences there. Check the sender's profile photo and headline, since members often look at it before replying.

A rule that shapes your design: a Not Interested button is required, and LinkedIn applies it automatically as one of the five buttons on the intro message. When a member clicks it, they can delete or archive the ad, and LinkedIn reduces how often that member sees ads from the same ad set. That leaves you four custom buttons on the first message. Conversation ads fit best with narrow, well-defined audiences, such as a company list or a title list, because each send is a one-to-one interruption. They pair well with Lead Gen Forms, since the form can open from a button and prefill the member's details. Remember that you can use a Lead Gen Form as a destination, which keeps the reader inside LinkedIn.

The usual mistake is building too many branches. Every extra layer loses people who would have converted at the first step, and a four-option menu with nested follow-ups looks like a phone tree. A second mistake is writing the intro as a press release. The message should read like a note from a person, with a clear reason for contacting this reader. A third is using a vague sender, so that the message feels like spam. Personalization macros, such as the first name, fall back to generic text like LinkedIn Member if the member turned off ad personalization, so test how the message reads without them. Write each button as a clear action, such as Get the pricing sheet, and avoid vague labels like Learn more.

Keep the first version small: an intro message, two or three buttons that match different needs, and one clear destination for each. For example, one button for a demo, one for pricing, one for a case study. Run it to a defined list and read the button click rates after a week. If the Not Interested rate is high, rewrite the opening or narrow the audience. If clicks are high but conversions are low, check the destination page. Review each branch separately. A branch that nobody picks can be removed, and a branch that converts well deserves a stronger destination. Export or note each branch's click rate weekly and prune the branches that nobody chooses.
