First I'd start off talking about a print shops pain point. Right now they're nodding in agreement and thinking, "man, I know! I have that same problem." Notice that my focus keyword is in the first sentence (and the title, and the peramlink - bonus!).
Then I'd make them feel better by saying how 90% of print shops using Avanti are making this common mistake. A screen capture or image with the alt tag containing my keyword would earn me brownie points.
Next, I tell them how to fix the issue. And everyone is happy again. Thanks Avanti, you're the best for print shops. (There's that keyword again. Enough times, but not spammy).
PS: you have to save a draft before you can set your permalink.
