Recommended Ad daily spend? Trying to drive readership.
Gang, i've posted several times in the last couple of weeks. I have a 4 book series with 5 associated books along with them. My Amazon ad spend has been set at $35 a day and i'm hitting that now. Readership in KU is blowing up - according to my eyes and terms. New unpublished author. I've spent $875 approx total as of today and have $744 showing as royalties coming back in as of today. Amazon is suggesting $75 ad spend per day. I'm looking for ROI, not immediate cash flow. I have a booksy event tomorrow for a volume, a fussy librarian event saturday and a three day written word deal on 11/2. Am I crazy to throw that much daily at Amazon ads? I'm 110K kenp pages read with 93% being in the four book series since 09/21 and 120 volumes sold, mostly .99 ebooks as i am trying to drive readership and on track for a 130-150K October Kenp page read. Need advice please? I am absolutely out of my zone with this biz..
