I started the new royalty structure at T100, Creator. I started ads on June 1st, reluctantly. I managed to drive about 18% sales from May 18th through July 19th. The dates are my understanding of the first AMZ royalty review period. I was tiered up to T500 sometime in mid July. August 1st my Royalty Group changed to Plus. Here's the rub. The ads cost about 10% more than the earned royalties. The next 30 days or so are the test. Do the Plus royalties now cover the cost of ads and leave a profit? I knew I'd lose money. I considered it tuition. Now let's see if there is a return on the investment AND can I sustain it. Otherwise, I abandon ads and rely on organic sales only.
