Thought Leader Ads versus single image ads: what the numbers show and what is contested

What a Thought Leader Ad actually is

A Thought Leader Ad promotes an existing organic post from a LinkedIn® member — a founder, an executive, an employee, a creator — under that person’s name rather than the company Page’s. LinkedIn’s own description: “Use Thought Leader Ads to promote content from LinkedIn members, creators, or employees of your company which can increase your reach and help you meet your brand goals.” Everything else about the format follows from that one design decision. The post looks like a person talking, because it is one. Source: LinkedIn Help, Thought Leader Ads.

What is eligible, and what quietly is not

Eligibility is narrower than most shortlists assume, and it has changed since the format launched, so we quote the page as it reads today. Eligible: single image, video, text, article, newsletter and collaborative posts. Not eligible, in LinkedIn’s words: “Celebrations, documents, polls, and multi-image posts aren’t eligible for promotion at this time. Reposted content isn’t eligible for sponsorship.” That removes a surprising share of “posts we could promote”: a repost, a document carousel and a multi-image post are all off the table. Check every candidate post against that list before the strategy deck is written, not after. Source: LinkedIn Help, Thought Leader Ads.

The permission step people discover late

The advertiser requests permission to sponsor the post from inside Campaign Manager. The author receives an email and can approve or reject the request, and can manage automatic approvals for future ones from their own sponsorship permissions page. On the company side, the person creating the ad needs super admin, content admin or Sponsored Content poster permissions on the associated Page. Sources: LinkedIn Help, Thought Leader Ads and Manage requests to sponsor your posts.

Treat this as a real dependency in a client engagement, not a formality. An executive who is travelling for two weeks is a two-week delay on the campaign, and a founder who has never heard of the request will not approve it from a plane. Get the approvals before the launch date is agreed.

Which objectives they can run against

Thought Leader Ads run against the Brand awareness and Engagement objectives, with Video views added for video posts. That is the whole list. Then the sentence that turns objective choice into a strategic decision rather than a dropdown, from LinkedIn’s ad set settings page: “The marketing objective you select determines which ad formats, bidding strategies, and optimization goals are available for your ad set.” Choose the objective and you have chosen the bidding, the optimisation and the formats you can use. Sources: LinkedIn Help, Thought Leader Ads and Understanding settings for ad sets.

The missing CTA button, and what it means

From the same help page: “A call-to-action (CTA) button isn’t available for single image or video ads, but URLs can be added to the intro text. Event Thought Leader Ads include a CTA button.” This is the clearest evidence that the format is built for brand and engagement rather than direct response, and it is a more useful fact than any uplift percentage. A post with no button is a post you read. It is not a post you convert on. Source: LinkedIn Help, Thought Leader Ads.

Lead Gen Forms: what LinkedIn lists, and what it does not

LinkedIn’s Lead Gen Form specifications page lists the formats a form can be attached to: single image, carousel image, video, event, message, document and conversation ads. Thought Leader Ads are not on that list, and the Thought Leader Ads help page does not mention Lead Gen Forms at all. “Not listed” is the honest description. We do not say “not supported”, because that is a claim we have not verified either; we check it inside Campaign Manager for the account in front of us. Source: LinkedIn Help, Lead Gen Form specifications.

The mechanism that matters, with no conversion rate attached: LinkedIn describes the form as one that will “automatically populate contact and profile information when a member clicks on your ad’s call-to-action button”, so the member does not retype their details.

What single image ads still do better

A CTA button. Lead Gen Form support. Every conversion objective, not two. Complete control of the creative, the offer and the wording, because the ad is written as an ad rather than borrowed from a feed. And a comparison that is actually readable, because one variable changes at a time. None of this makes single image ads better; it makes them a different instrument.

The part that is contested, and why we will not quote it

Figures circulate comparing the cost per click of Thought Leader Ads with the cost per click of single image ads, and they are repeated across agency blogs and conference slides. They do not appear here, for four reasons.

No LinkedIn-owned page publishes either figure; we checked the help centre and the ads guide on the date at the top of this post. The sources that do publish them name no methodology, no sample size, no period and no industry. The two formats usually run against different objectives, which changes what is being charged for, so the two numbers are not measuring the same event. And audience expansion “is automatically enabled on ad sets where it’s available”, with reporting that “will include activity from both your target audience and expansion audience” while the forecast “won’t include member accounts from audience expansion” — so two campaigns can be reaching materially different audiences while appearing to be a like-for-like test. Sources: LinkedIn Help, Use audience expansion in your ad set and the LinkedIn Ads Guide.

How to run the comparison properly in your own account

Six conditions, all of them at once. Same objective on both ad sets. Same audience definition. Same period. Audience expansion switched off on both. The LinkedIn Audience Network setting recorded, and identical on both. One variable changed — the format — and nothing else.

The answer you get is about your account, your offer and your audience. It does not transfer to anyone else’s, which is exactly why the numbers in circulation are worth so little.

What we do with this in a client account

Thought Leader Ads at the top of the funnel, where a named person has posts worth promoting and has agreed to it in advance. Single image and document ads where a form fill or a click is the point. Retargeting between the two, so the person who read the founder’s post is the person who later sees the offer. No claim about what any of it will cost or produce; that is what the comparison above is for.
