The Bestseller Guide To When You Should Publish Your Book

Over the course of the last couple of years spent crunching numbers for this blog, surfing dodgy creative social media and keeping my eyes open (in the darker hours) I’ve come to the conclusion that there are two pieces of advice all authors would do well to live by.

The first is to stay far away from tight undergarments. The second is never to trust a man called Gerald who tries to sell you a second-hand generator in a pub.

Just kidding. The advice relates to the publishing of fiction. I just needed to have a bit of fun before I whack readers in the face with some heavy-duty graphs. I’ve been going easy on you recently, with all that talking to my arse, not to mention tributes to hairy Irishmen, but all that has to stop now, for a bit of business.

Now read this advice very carefully, for I will only say it ad nauseum until I’m blue in the face saying it. It’s aimed at both traditionally published authors and self-published authors or indies: anyone who is not a best-selling author already, in fact.

  1. Don’t bring out your book at the same time as a blockbusting heavyweight. There can only be one loser. It’s going to be you.
  2. Unless it’s important for your book launch to be timed with a specific event or anniversary, launch when the book market is relatively quiet.

And how are you supposed to know when it’s quiet, I hear nobody asking? Well, that’s where nerds like me come in. Below I have some lovely graphs which are all full of colours and sweet, glorious little numbers which show you what the big publishers already know: the times of year when people buy more books, and also, when sales tend to drop. Also, I have a few insights into when the big hitters released their books in the 12 months from June 2014 to May 2015. They didn’t just pick their launch dates at random. They had their reasons, and so should you (for avoiding them).

I referred to this before, in October 2014, when I only had 5 months’ data, but now it’s time to look over a full year of Nielsen Bookscan data, as published by the Sunday Times (UK). Back in What Time Of The Year Should You Publish Your Novel? I said:

Although the base data obviously only includes the top 10 bestsellers from each week (and is in itself far from perfect, given the issues still surrounding e-book sales data) the exercise still suffices for what I want to look at: Trends. Sales trends and outliers, to be precise.

The data sources are the same and the caveats unchanged, so on we go.

First, let’s look at those actual sales: a full year’s worth, this time. Greens are highs, reds are lows.

When Should You Publish Your Book? Bestseller Data Gives Us The Answer

What does it all mean? As you can see glaring at you from the above (I changed those colours three times in an effort to make them prettier, so if you don’t like them, I won’t listen), hardback sales – i.e. blockbuster new releases – peaked in the pre-Christmas market, whereas average paperback sales peaked in June. Even though overall sales were higher in the months from October-December, people bought more paperbacks in June than any other month.

And why is that? Holidays, of course. Some people only read on holidays; some think they’ll read, and don’t; some always read, and double up on their break. It all means the same thing: overbuying, mostly.

What does that mean for you? People planning on publishing digitally should be taking advantage of the holiday market, and the sorts of people who don’t want to lug hardbacks around with them while they’re practising Camel Mindfulness in Bolivia.

Great! That’s my first million in the bag! Er, no. Big publishers know this. They knew before you did. Therefore, do not launch in June, because you’ll be ground into a pulp by the major blockbusters who will eat up all the headlines and pocket money. Launch in April or early May instead. And look at the quieter months: they are also a good time for indie authors to release – September, March and April in particular.

Really? Prove your point.  June 2014 saw major paperback releases from James Patterson, Lynda La Plante, Helen Fielding, Karen Slaughter, J.K. Rowling T/A Robert Galbraith, and the lesser-spotted Donna Tartt. June 2015 saw the release of Grey by EL James. Nuff said.

And furthermore: Keep up with the news. Read the Culture sections in the broadsheets. What’s the big release they’re all talking about? Avoid that launch week like the plague. Your dates can change, theirs won’t. You want to compete with that kind of noise, go right ahead. But don’t come crying to me when punters walk right past your triumphant book launch to buy something famous.

The following graph illustrates the overall numbers, with no split between paperbacks and hardbacks. And if you’ve been behaving yourself, and reading properly like I told you, they will back up all the things I just said. However, I am now going to blow your mind, by turning the theory on its head somewhat.

When Should You Publish Your Book? Bestseller Data Gives Us The Answer

Here we see August 2014 was the quietest month over this period, but I wouldn’t recommend launching then either, because your friendly local journalist will generally be on holidays – psychologically if not physically. Your friends will also be away, and whatever you sacrifice, you absolutely cannot sacrifice their obligation to buy three copies of your book, plus one for the dog.

Conversely, December was the biggest month for book buying, but all the promotion for the biggies is usually done and dusted by November, which means there could actually be headspace for your marketing might. I did see some data which suggested that promotional activity taken up in late December got good results. Perhaps by the time the turkey’s carved, everyone is so sick of Christmas that they just want to curl up with a new book which didn’t have a bow on it.

So there you have it. If anyone has a real-life launching experience which could help or hinder any of these theories, speak now, or forever hold your purse.

And while we’re at it, if you like these numbers as much as I do, please vote for me in the Irish Blog Awards, which I covet most unwholesomely in 2 categories this year… voting is only open until September 21st, so time is running out. Vote for me in Best Art & Culture Blog here, and in Best Marketing & Communications Blog here. Thank you!

    Looking back on it, I think my last two books came out in July and May . . . and both of them tanked. However, your data and advise has given me a plan: I call it Book Title Shimmer. The unscrupulous author, ie me, checks the literary press for the dates of the blockbuster releases, and then launches my book, but with a temporary change of title.

    Hence – EL James releases 50 Shades of Greyness, a sado-masochistic tale of erotica, at the same time as 50 Shades of Greyness, a paranormal conspiracy set in Wurzburg. And then after Christmas the Wurzburg Grey reverts to its original title (that’s the ‘shimmer’ see…) and all those thickos read my book wondering who taught EL James how to write proper.

    I’ll give you a credit for the idea in the credits section of the book and in my opening statement in court.

    You’ll be happy to hear that my personal experience completely agrees with your data. Also, August sucks. It’s amazing how deep a dip (see what I did there?) my sales take each August. I’ve already sold more books in the first week of September than in the whole of August.

    Conversely, December is a wonderful month. Even with all the competition, my promos have been as much as ten times (!) more successful than during other months.

    Thanks for the number-crunching. I wish there was some data for ebooks, although I suspect that wouldn’t change the distribution significantly.

    Thank you for this, Tara! On Nicholas’s desire to compare/crunch the numbers, someone numbers-savvy might be able to do using the data, so helpfully supplied by The Data Guy and Hugh Howie, at to correlate for ebooks. It’s only Amazon data, but well, Amazon is Amazon… 🙂

      You’re more than welcome, N.E.! I’ve seen their graphs and they’re pretty comprehensive – they have a huge amount of data already published and who knows, maybe they’ve looked at the seasonality already. David Gaughran has done good rundowns on their data on the past, too. And I can only dream of having the Amazon data on this stuff. But a girl’s got to dream…

    This all seems good sense to me except for one thing. Sorry, I feel sure that you know there is going to be a “But” in everything that agrees completely. I am no expert but have had two publishers in my life. Most of my books are self published. They (The publishers) say the optimum time for a book release is August. Too late for the summer audience too early for Christmas you may think and it is down time for book sales. I asked why? They, in turn, replied; people don’t buy any shit for christmas they have to be sold it. Launch a book in October you are only gaining momentum in November and most have bought everything. Launch in August and you have gained momentum for the Christmas sales. Every radio show, magazine and/or blog that is happy to have you. you have to be there. I cannot say that this is a definitive answer in any way, but it has worked for me. Launch in february, for the summer or August for Christmas.

      I don’t mind buts at all! In fact, regular readers of this blog will know my penchant for buts!

      I see what you mean about August. Perhaps however (see, another but) it depends on where on the ladder you are, as an author, and what sort of momentum you mean. Usually local media (in this country anyway) is more interested in newly-launched books, than in books which have been out for a few months and not doing much in the meantime. Do you mean momentum from reviews, etc.? Because that could be solved with advance review copies, with a launch boost in the media closer to peak market time.


  7. September 11, 2015 at 9:29 pm

    Hmm, I’m looking at this with considerable interest. My self-published paperback fiction last year was officially published on December 5th, but I did all the party stuff in November and emailed and snail mailed everyone I knew or was related to, so they felt obliged to buy each other copies (of an upbeat book about suicide) for Christmas. This worked remarkably well as I could tag onto local Christmas fairs and even sold copies of my previous novel.
    Next year I will be having a non-fiction hardback published in July (it should by been June, but daughter 2 is getting married then). The fiction hardback figures for July don’t look great. Do you have non-fiction figures? Though this is probably niche publishing (military) and won’t follow the general pattern.

      I remember you publishing around Christmas, Hilary, and I thought at the time it might be a good idea, given that late November/early December is a great time for your immediate and intermediate circle to feel the need to buy your book for all their friends! The data I’ve seen since on the response to Nicholas Rossis’ December ad campaign suggests the same thing.

      I’m afraid I’m a bit useless to you on the non-fiction side of things, I didn’t collate that data. I’d say in a broad sense they follow the usual trends – as people who rather non-fiction are book buyers just like anyone else – but I would say that if you can tie your military history in with an anniversary or other relevant date, and hit up the media in advance with story proposals, you could get fantastic coverage by timing it wisely.

      I for one am convinced that Twitter is useless for marketing books. There’s too much noise on the platform and I just mute anyone who incessantly sends out “BUY THIS BOOK!!!” tweets whether it’s for their book or anybody else’s. I don’t think anyone can sell a book in 140 characters. I’ve been begging authors to stop flogging their books to death on Twitter for years.

    Do you think major book festivals like the Edinburgh Book Festival have a significant affect on book sales? Edinburgh is in August and they appear to move vast quantities, but perhaps not significant in the grand total of sales.

    • September 16, 2015 at 7:50 pm

      I suppose it depends on the size of the festival… it would have to be something the size of Hay with its accompanying TV coverage to have a significant effect on national book sales, wouldn’t it?But any exposure at a festival will increase sales, as long as they’re available nearby.
