Simply mention the product name repeatedly, throughout the ad.
The good news is that the Client will probably really like it.
And it will sail through research.
The bad news is that it will almost certainly be a terrible ad.
Here's another example, the (in)famous Go Compare campaign.
But what if it's a print ad, I hear you ask?
Simple, just make the ad out of the logo.
It's a shame I couldn't find my all-time least-favourite example, a poster from the UK for budget hotel chain Premier Inn, which showed a little girl snuggled up in bed, cuddling their logo.
She really loved that logo.
