Got burned on freeebooksdaily.net. I paid the fee after the site owner replied that he had my date free & then I never heard back from him & never got my promo. I had to push a claim via PayPal to get my money back, then the bloke replies to me about a week or two after that & apologized & promised he would do my promo for free, which he didn't. Anyway, stay clear from this site & don't confuse it with freeebooksdaily.com which is legit & costs only 3 bucks. Freebookshub.com is also not worth it. I paid 10 dollars and only got 12 or so freebie downloads. I had a good experience from EbookSoda for only 10 bucks (100+ freebie downloads of An Empire Of Traitors), and now I've scheduled 3 promos for the 24th of this month with Ebooks Habit, ItsWriteNow, and the Fussy Librarian. Using similarweb.com I found that BKnights (only on Fiverr) really suffered a downfall in their visits & email responses. My last promo with them on September gave me half of the regular freebie downloads I get from them (1/2 out of 160+). BKnights/DBS have a cool business policy, they're very open and responsive & they do offer refunds if satisfaction is not met. Hope their traffic will improve for the holidays and into the new year.
As a great tip, don't rush to throw your money away on ebook promotion sites. From my experience, look at any promotion above 10-15 dollars with a LARGE grain of salt. And always type in the site's main URL into similarweb.com to see visits, bounce rate, ranking, and email & social media traffic sources for the respective site. What I personally do is multiply the visits with email traffic percentage then divide by 100 to see a figure closer to reality (approximation of active members) vis-a-vis so-called email blasts & newsletters. Note: make sure to include the www. into the search field, otherwise chances are the site won't recognize the address.
I will update this blog entry once I've seen the results of EbooksHabit, Fussy Librarian, and ItsWriteNow.
