When you have an Amazon deal live for a product, your PPC conversion rate increases, right?
Not always. Sometimes it drops.
The lower price and deal badge can attract less qualified traffic.
So click-through rate and spend goes up - but conversion rate drops.
It's worth tracking how each of your top products perform on deal.
On some products you may want to keep spend high, on others it might work better to reduce budgets pre-emptively and preserve profit.
