From Indies Unlimited:
I (Julie) ran an ad for one of Bob’s contemporary fiction genre books at a sale price of 99 cents on March 21, 2015 with:
eBookBooster $25 (eBookBooster is a site that agrees to send your ad out to various sites, 25 sites for $25, including Awesome Gang, Sweeties Picks, Ebook-Saurus, eBookLister, and maybe HotZippy – maybe was their word, never did know if it was included or not).
Sold 2 books total.
I thought they couldn’t all be that ineffective, so I decided to try some of eBookBooster’s sites directly. Yep, they’re all that ineffective.
Ran an ad for a different book in March with:
Read Cheaply ($15)
Ebook-Saurus ($10 for premium listing)
Ran an ad on April 10 with Awesome Gang ($10 for featured book listing)
Ran another ad with EbookSoda ($10)
Ran an ad in November for BKnights ($5)
Have tried multiple ads with Fussy Librarian ($15)
Never sell more than 3.
To summarize, with ads through EbookSoda, eBookBooster (including Awesome Gang, Sweeties Picks, Ebook-Saurus, eBookLister), Read Cheaply, BKnights, and Fussy Librarian, I spent $120.00 and sold a total of 14 books. At $0.35 per book, That means Bob took in $4.90, which translates to being down by $115.10.
