Which Days Are Best To Promote Your Free KDP Select Book?

For Readers: Which day of the week is most popular to look for a quality free read?

For Writers: Which Days Are Best To Promote Your Free KDP Select Book?

An author enrolled in Amazon KDP select has 5 days out of 90 day period to list their book for free as a promotional tool to entice readers to read their book. Which day(s) are best to promote your Free KDP Select Book? Worst?

Well the analytics people at Digital Book Today took a look at this question that Amazon refuses to answer. They crunched the numbers for 28 weeks (196 days) from their popular sister site The Top 100 Best Free Kindle Books List which features predominately small and independent author titles that are free for a limited time. Titles listed meet the minimum guidelines of 13+ reviews and 4.0+ stars. This is a stronger list of proven reads than the Amazon Top Free list (in our opinion). It should be noted that The Top 100 Best Free Kindle Books List is presented like the front of a bookstore. The bestsellers without being broken down by genre. A great place to look to see what is available and maybe you will find a great read that is not in your normal genre which is a delight to any author. Some book buyers never venture any farther than the front of the store before they have their arms (or eReaders) full of books to enjoy.

Before we get to the actual graphs, lets talk about the data. Of course The Top 100 Best Free Kindle Books List is just a small sample of the total amount of traffic that is sent to Amazon by the many book web sites on the internet. Another site could easily have completely different results. Our data is based upon visits for this time 28 week period.  The Top 100 Best Free Kindle Books List is updated daily.

A few last topics before we get to the data:

  • This article is not about the pro’s and con’s of an author promoting their book for free. That topic has been covered extensively on other blogs.
  • The data does not reflect the quality (in terms of ratings/# of reviews) or the number of free books that are free on given day. Sounds like another interesting topic. We have that data. Stay tuned for that blog post.

No fancy infographics. Just the standard Excel graphs.

Dates for Data: 2/26/2012 – 9/8/2012. 196 days. 28 Weeks.

We compared and ranked traffic on a Sunday – Saturday basis for each week. Lets look at an example.

In the example above Monday had the highest percentage of traffic in a day for the week. Friday had the least amount of traffic.

In the example below the results are entered into the table from the data above.

Now for the fun stats.

The table below has the info for each day for each of the 28 weeks in our sample. All totals indicate 28 occurrences for each day.

What does this tell us?

  • Wednesday had the highest traffic (8 times out of 28 weeks).
  • Saturday and Sunday tied (10 times each) for the least amount of traffic.

    Thanks for posting that! I had been under the impression that the weekend was the best time for free. Huh. Good to know!

      Shawn,

      Just remember that these are just for our site. We hope to get our next post out by next week that shows which days have the most free books available on Amazon. Just looking at the raw numbers it points to Saturday and Sunday.

    Thank you Anthony for your informative statistics! You are always doing great things for the author out here. Thanks so much and have a great day!!
    Take care,
    Sandy Jones

    Anthony, Thanks for the info. I would have thought Monday was the best. Go figure, huh?

    • September 20, 2012 at 11:11 am

      Stephen,

      Actually Monday is not very far behind statistically. On our site overall M-F are good days. The stats just show that Saturday and Sunday are slower. On DigitalBookToday.com the traffic has the normal ups and downs with no real day standing out for traffic.

      These stats are for the segment of people who are shopping for free books, but these same people also buy books (and other products) on Amazon as they click through. We simply would not be maintaining this site if there was not a business return for us.

      One odd or interesting stat since we have have other non-book sites that we have been running for years but the book sites follow the same pattern. We see blips in traffic between 8:00AM-10:00AM on Mondays and between 2:00PM-4:00PM on Fridays. I would guess this increase is from workers in cubicles either delaying the start of their work week or hoping for the end of the Friday workday!

        I had thought Wed – Fri would be best but it looks as though Mon-Wed would actually be better. Interesting! Thanks for the stats.

          JR,
          What we don’t have in the stats are the actually percentage for each day. There is not a lot of variance on the Monday-Friday days. All are effective as long as an other has other marketing efforts planned on the free dates.

          TO SEE THE RAW DATA:

          Due to request we have created another page with just the raw data. This will also help clarify that there is often not a huge difference in traffic among the days of the week. You can also check the traffic for holidays. This page may load slow due to the size of the image. Below is the link.

    Hi, Anthony,
    You have provided a fine service by compiling and publishing this data. As we talked a couple weeks ago, your results jibed perfectly with my own on my uses of KDP Select Free Promos, however, my sampling was much, much smaller so yours is of great interest to me. Thanks, David

    Anthony,

    Great analysis. For what it’s worth, and I’m just one person so this isn’t a scientific survey, I’ve offered my book for free several times. Without exception, it has netted me more downloads (and later sales) by being free on a Tues or Wed (Monday has never worked all that well but it hasn’t been terrible.) The worst time I made it free? Over a weekend.
    In other words, your data feels right to me, just based on my own experience.

      Rob,
      Thanks for the feedback. We need to get the data compiled for the number of books offered for free on any given day.

  6. September 20, 2012 at 11:56 am

    Wow! Who woulda thunk it?

    • September 20, 2012 at 12:15 pm

      Just remember the info is just for our site. I am sure sites vary.
      Thanks for reading and commenting.

    Just adding my thanks for this — and for ALL you and your site do for indie authors.

    This author appreciates you!

    • September 20, 2012 at 4:05 pm

      Thanks for the mention on your site.

  8. September 20, 2012 at 3:35 pm

    Thanks for the great information. I’ve always found that having free days Wed-Thur or Wed-Friday was best because then you usually get more sales on the weekend when people are shopping and buying. At least that is what has worked for me.

    • September 20, 2012 at 4:05 pm

      Deanna,
      Now that is an interesting concept. Wouldn’t it be nice to know what Amazon’s best day is for selling books?

  9. September 20, 2012 at 4:01 pm

    Anthony,

    As far as I’m concerned you ROCK! Anyway, I’ve done a few free days and you know what? Wednesday was the best day.
    Thanks for sharing these numbers.

    • September 20, 2012 at 4:09 pm

      Susan,
      Thanks for the kind words. I might have to put a note on our submission page to let authors know that Wednesdays might be harder to get their books listed. Our list for next week is already growing.

  10. September 20, 2012 at 4:53 pm

    Great info. Thanks, Anthony!

  11. September 21, 2012 at 7:43 am

    I am not really a number cruncher as far as doing analysis that much, but I have tried different days and noticed that it seems you get different results on different days even though you may promote the free books in the same way. Thanks for sharing your analysis,

      It may seem there are different results even though we promote the same way everyday, but there is always one big unknown on a daily basis. What are the current algorithms for the search engines.

      We also have spikes in traffic for a day or so depending on publicity such as: a popular blog listing our link or being pinned on a popular Pinterest board.

      Thanks for visiting.

    I’m late to chime in, but I want to add my appreciation for this information to everyone else’s. Big business has to pay a ton for data like this! Thank you, Anthony, for providing it gratis. It’s so helpful having this sort of insight when planning a marketing campaign.

      Barbara,
      Thanks for the commenting and I hope it helps you out.

  13. October 1, 2012 at 3:46 pm

    This is definitely an eye-opener. Like some of the others commenting here, I also thought the weekend was best. Now I know!

    • October 1, 2012 at 5:09 pm

      Sharon,
      As I have pointed out before that this traffic is just for our sites. It could be much different on other sites. Thanks for stopping by.
