When I have great pricing on a line (or even a single item), I like to experiment with having “Sale” in the headline. I used to do “on Sale” a lot.
For example, let say you have great prices on Viking Grills.
You could do a boring headline that’s just “Viking Grills”.
But I’d say also try “Viking Grills on Sale”.
But I’ve learned to try other variations. I can’t give them all away here! But let me give some examples.
“Viking Grill Big Sale”
“Viking Grill Blowout Sale”
Besides standing out more, it also has a connotation of an event. A sale event, rather than just everyday on sale.
Try those variations (at least those you can fit within 25 characters) and see what kind of CTR you get!
