A LinkedIn Ads form that went from 1.6% to 6.1%
I inherited a B2B SaaS account with one campaign, one creative, and a cost per lead that didn't add up. The problem was the form.
1.6%to 6.1%
Form completion rate
8.08%
Video CTR
Where it started
B2B software company, long sales cycle, buying decisions made by committee. The account had been running for months on a single active campaign with one creative that had long since run its course. Cost per lead climbed every week and nobody could say why.
The number that sent me to the form was the completion rate: 1.6%. Out of every hundred people who opened the native LinkedIn form, ninety-eight closed it without submitting.
That number says something specific. The ad worked well enough to get the click and open the form. Whatever was failing happened after that.
What I found
The form asked for seven fields, phone number and company size among them. In B2B, asking for a phone number on first contact means asking someone to accept a sales call before they know whether they care about you.
The campaign ran against one broad audience, putting profiles with completely different needs in front of the same ad and the same form. The creative was a static image that had been rotating against the same people for months.
There was also a measurement problem: LinkedIn was counting leads that never reached the CRM. Cross-checking the two sources turned up a gap nobody had looked at.
What I did
I cut the form to four fields and changed the order. Work email first, phone number gone.
I split the campaign by segment and by intent, each group with its own ad and its own form, instead of one large audience receiving the same message.
I made video the primary format, with three different hooks, to see which one held attention past the first three seconds.
And I went through the LinkedIn-to-CRM handoff to stop counting leads that didn't exist.
Results
Over the quarter:
- Form completion: from 1.6% to 6.1%
- Video CTR: 8.08%
- Lower cost per qualified lead on the same budget
What I took from it
The form is part of the campaign. Bids, audiences and creatives get optimized for months while the form sits exactly as whoever built it left it on day one. In this account, four fewer fields moved more than any targeting change.
