Ingmar

We're creating a LinkedIn ad for a new B2B product. What needs to be in it to make you click?

To be honest, if I were to look at a LinkedIn ad, it would have to say that it makes my job easier and allows me to complete my tasks with more independence.

Kelly

We're creating a LinkedIn ad for a new B2B product. What needs to be in it to make you click?

If it's a B2B product, it needs to get straight to the point. What's in it for me? And fast. No long-winded rambling.

Anna

We're creating a LinkedIn ad for a new B2B product. What does it need to include to get you to click?

So, to get me to click, the ad really has to show exactly what the product does. Not just marketing fluff.
