I thought I'd report here that the $7 Hidden Gems ad last month may have accounted for four sales: 4 x .35 = $1.40. Then again, maybe my newsletter peeps, whom I informed of the Kindle Countdown deal, were the ones who rushed to buy during the sale.
I have the remaining ad ($10) coming up in a few days. Can't say I'm expecting much. I promised myself I would advertise in new venues this year, and Red Roses did okay for me once but not with a second title. I was lucky enough to get those three international BookBubs, but otherwise just about every ad has been a failure. The tail on the BB ads has run out, too. Now it's time to try again to get a Google Ad going.
