Occasionally, I receive emails from readers upset about my word choice.
They object to the phrase to suck. They don’t like my reference to sex in idea sex. Or they hate the phrase shitty first drafts.
Even the word stinky got banned when I wrote a guest post several years ago.
Word choice is personal, and it’s hard to please everyone. So, I tend to follow my gut feeling. I don’t swear in my writing, and I mostly avoid harsh language.
Today’s topic is slightly different.
It can also lead to heated debates.
But while word choice is personal, a strong reason exists to ignore the style guides when it comes to writing out numbers.
Shall I explain?
What style guides suggest about numbers in writing
Style guides present different advice on writing numbers as digits or words.
The MLA style, for instance, suggests spelling out numbers when you can write them in two words or less. So, thirty-five, eleven hundred, and one third. But: 301 and 1,107. But the APA style suggests only spelling out numbers below 10, so nine and three, but 11, 100, and 1/3.
For online writing, I suggest going a step further than APA and using digits for all numbers apart from one or two. For huge numbers, use a mixed approach, such as 24 billion or 7.2 million.
Why?
As an eye-tracking study by usability expert Jakob Nielsen suggests, online readers fixate on numbers:
Because numbers represent facts, which is something users typically relish. Sometimes people are looking for specific facts, such as a product’s weight or size, so product pages are certainly one place where you should write numbers as numerals. But even when a number doesn’t represent a product attribute, it’s a more compact (and thus attractive) representation of hard information than flowery verbiage.
People associate numbers with facts, and that’s why they can add substance and credibility to your writing. Moreover, numbers attract attention because they’re differently shaped from letters. This is why they stand out in social media streams, in inboxes, and on web pages.
As an online writer, writing most numbers as digits is an easy way to draw attention and boost your credibility.
So, how can you add more numbers?
1. Numbers in subject lines and headlines
You can add numbers to headlines in various ways. Want some examples?
The most shared post on Copyblogger in the last 12 months is a list post:
And the most popular post on Backlinko uses a big number:
And the most popular on Moz.com uses a year:
And the second most popular post on the Art of Manliness refers to an old year to arouse curiosity:
All of the blog posts above received thousands of social shares. (Note: thousands is not a specific number, hence I spell it out).
Of course, this is just a snapshot. Yet, several studies suggest that headlines with numbers outperform headlines without numbers:
- This study by Conductor suggests that a headline with a number outperforms a how-to headline by a factor of two
- This study by Buzzsumo suggests the numbers 10, 5, 15, and 7 generate the most engagement on Facebook
- This comparison of Buzzfeed listicles suggests that odd numbered posts may outperform even numbered posts
Of course, adding a number won’t magically make shares for an average post soar. Write a valuable post first, and then see whether you can add a number to attract attention and boost social sharing.
2. Numbers on your sales page
The most common place to use numbers on sales pages is at the end of the page where you sum up your offer, and nudge people to buy.
Here’s example bullet points at the end of the sales page for the Write It Don’t Fight It course, explaining what you’ll get:
- The Joyful Writer ebook: a 58-page PDF with down-to-earth guidance on how to unclog your mind, so you can work with your inner critic and write with more joy
- The Write It, Don’t Fight It workbook: a 50-page PDF with 26 recommended activities to apply your learning, experiment and challenge yourself to write faster, more regularly, and with more joy
- The discussion video What Sports Pros Can Teach Us About Motivation, Habits and Peak Performance (22 minutes)
Be careful. Don’t focus just on numbers to add substance and specificity. Add a benefit, too, for optimal persuasiveness.
Next, where possible, get numbers included in testimonials. Here’s an example from Newfangled, explaining the results of their content marketing advice:
(…) they are adding over 3,000 words of unique, high-quality, indexable content to the website every month, resulting in a 40% increase in web traffic, a 40% increase in organic search traffic, and an astonishing 2,500% increase in email traffic.
Persuasive, eh?
The rule in persuasive writing is we appeal to emotions first, then use facts to justify a purchase. So, at the start of a sales page, you paint a picture of what your offer will mean to customers—how will it change their lives?
Even here, you can use numbers. For instance, Case Study Buddy, uses numbers to explain why case studies will make a big difference to your marketing:
- 62% of US agency execs cited case studies as the most effective content for lead generation.
- 77% of B2B buyers cited customer success stories as the most influential content they consumed.
- 65% of B2B marketers ranked case studies among their top 3 most effective content types.
Be careful. Your objective is not to use numbers at all costs—only use numbers at the start of the page if they help you explain why your service or product will help make your customer’s life better.
One more example?
If your sales page includes a snippet about you and your company, you can add a number, too. Karyn Greenstreet instantly boosts her credibility as mastermind facilitator and trainer like this:
Hi, I’m Karyn Greenstreet. I’ve been running mastermind groups since 1994, and teaching people to start and run successful mastermind groups for over 15 years.
In headlines, you mainly use numbers to attract attention and get more clicks to your content. But in sales copy, you use numbers to boost your credibility and make your offer more persuasive.
Have you thought about what numbers you could use?
Bonus tip: When to visualize numbers
Do your readers grasp what your numbers mean?
Some numbers are so mind-boggling that we can’t really understand their impact. In this case, try visualization. For instance, in a blog post about creating a lesson plan for an online course, I start with a statistic:
The global market for online courses is estimated around $107 billion. A mind-boggling figure, right?
As this number feels difficult to grasp, I continue by visualizing the number:
Imagine stuffing one-dollar bills into a 53-foot truck. Depending on how crumpled your bills are, you’d need around 1,000 trucks stuffed up to the roof to transport those 107-billion dollar bills.
Would you like one of those trucks to deliver a heap of money to you?
A more common way to visualize such a number is to calculate how many people it could provide for. But I chose the truck visualization because I could get back to it at the end of the post:
Can you hear that truck honking?
The driver leans out of the window, a smile on his face. He’s waving at you, ready to deliver a heap of dollar bills.
Tiny numbers can be as baffling as big numbers. Here’s a brilliant explanation by Grace Hopper of how long a nanosecond is:
Boost your credibility with numbers
Are you a style guide devotee? Feel free to stick to spelling out your numbers.
But if you’re not afraid of breaking the rules, write your numbers as digits to attract attention to your headlines and to add substance to your sales copy.
You’re the writer. It’s your choice. 🙂
I enjoyed reading your blog and I’ve learnt a lot especially on how to use numbers. I am a newbie in Copywriting but I believe that soon I’ll master the art. Thanks
I’m glad you’re enjoying my blog, Ezeigwe. Thank you for stopping by.
Love your bites and links to expand each tip. Thank you!
Thank you so much, Pat. Happy snacking!
I have another interesting question. When should you use abbreviations for words. Such as ” for inches, or in for inches. Ave for avenue, avg for average. There are so many. Thru for through and so on. It shortens the copy, but should they be used? Or better, when should they be used. Just asking. I have wondered for quite a while if I should use them in my sales copy.
As long as your readers understand an abbreviation, then it’s usually okay to use it in your writing but it also depends on your tone of voice.
Some of the abbreviations you mention are informal (such as thru or avg) and that’s a style choice. I personally wouldn’t use them on my website (I’d use them for a Whatsapp message or texting) but that doesn’t mean you can’t use them on your website. It depends on how formal or informal you’d like to be and who your target audience is.
Interesting one. I’ve long known the importance of numbers in marketing. But strangely until this very day I had been confused about which number format to use in my writing (!!!) – why have I not made the link before! I’d decided long ago to use numbers in headlines/meta titles as it’s easier to read, attracts the eye, I’ve heard the studies and a number usually takes up less space, but for some crazy reason I hadn’t made the link with body text until your post. I was still following an APA approach. Thank you Henneke, you’ve fixed a problem I’ve had for ages and still had this week! I don’t mind breaking rules and my ideal reader wouldn’t mind me breaking the rules either. Another awesome post. Thumbs up.
I am glad we could fix this together! 🙂
Honestly, the style guide I refer to when I don’t know what to do, is an English handbook intended for high school students. Sometimes I don’t like what it says, and then I just do whatever I want. A guide is a guide, not a law set in stone. A guide helps a person write for someone else, know what that person prefers, edit according to how we will BE edited. Editors love when we mind their preferences.
When we write our own copy for our own purposes, then we should do how we want. 🙂
That’s a good point about respecting another person’s preferences if we write for them. And otherwise, yes to this: “Sometimes I don’t like what it says, and then I just do whatever I want.”
Always good to see you, Katharine!
Yes, you are right. As online writer as well as free will, we should decide what is right rather than following dogma.
Your post on numbers with numbers as facts has really given a fresh perspective to relook at all styles. I will not only be aware about numbers, but also I will use your advise to improve my sales writing and blog posts. Ensuring, content has its substance.
Yep, no need to follow dogma if it doesn’t suit us. Happy writing, Shailendra!
Superlative post as always, Henneke.
My comment this time isn’t about your piece right now. No, I must have inadvertently deleted your last post which came yesterday or Monday (we’re in Australia).
Could you please resend because we don’t want to miss one of your posts. Thanks in advance for this and best regards – Paul Herring
Here’s this week’s post: https://www.enchantingmarketing.com/how-to-improve-writing-skills/
It’s a big one! I hope you’ll enjoy it 🙂
Hi Henneke,
Your post is helpful and I love the tips. I have been using the APA style, writing numbers below 10 in word form and those above as digits. It has been working, though. However, I will experiment with your style and compare results.
Thanks for sharing.
Some people find it quite hard to move away from APA style. I’d be interested to hear how your experimentation goes. Thank you for stopping by, Moss!
I always love reading your posts! I think you are spot on and that having a bit more choice to when to write out numbers can help grab attention and convince your audience. Thank you for writing such helpful articles!
Thank you, Angela. I’m glad you found this article helpful. Happy writing!
Par convention j’écris les chiffres en toutes lettre dans le texte ! je vais donc changer pour être plus performant. Merci
Interesting that the convention of writing numbers in words is similar in French. My French is not good enough to reply in French. 🙂
The ‘numbers’ post: Truly useful and practical – many style guides are a bit dense and also out of date – i.e. pre-internet.
The ‘loose’ (!) language:
In my classes I say: “If you wouldn’t hear it on the BBC, don’t
use it. And avoid Americanisation wherever possible.”
Sucks, shitty, crap, bugger, bullshit – these are lazy expressions that can be heard everywhere, on building sites, bloke-ey situations – talkback radio (ignorance talking to ignorance) . . .
As writing professionals, how about we lift the game and send the spiral upward instead of downward?
While I agree with the sentiment of making our discourse more civilized, it’s also true that as copywriters, we have to “speak” the language of our intended audience, so I don’t object to using strong language (even if I rarely do).
Damn right 😉
Let’s break the rules 😀
Always!
I have not blogged yesterday. For the second time in a month. If that is not a major rule-break!
First off, there once was a dog that by tapping its foot could count to 3 but that skill was not a recessive gene occurring every fourth generation. 🙂
In technical SOP’s sometimes a direction could be written as “…place 3 (three) gaskets onto the #9 bolt.”
Thank you Ms. Henneke for sharing your research and personal preferences for Content writing.
I like your suggestions and references noted.
What a smart dog!
I had to look up SOP – Standard Operating Procedure, and writing numbers as digits rather spelling them out as words seems to make sense because when the digits stand out, they attract more attention and it may feel easier to follow the instructions.
Thanks for sharing 🙂
Thanks Henneke,
Now I understand the proliferation of blogs and YouTube clips with titles like “10 things you didn’t know about…” and 15 life hacks to brighten your day” etc.
P.S. The image of the smiling guy with the truck full of dollar bills really made me smile! You have a unique way of creating ‘sticky’, memorable imagery 🙂
Yes, the 10 Things … and the 15 Life Hacks … feel a bit cliché but they do work (if the title promises something worthwhile and the article is indeed good).
I’m glad you like the guy with the truck full of dollar bills. 🙂
Wow! So many thoughts!
I’ve always stuck to writing out the one-syllable numbers within the copy and using numerals for all numbers in titles. The first lady who ever taught me about blogging said to do this. 😀
I’ve lately been taught that numbering lists that should be bulleted instead, was wrong. Only number lists when the order is important, such as in a recipe or a chronological list, but bullet all others. I don’t know. I think if I offer six ways to do something, then numbering the list helps the reader know how far he’s read and how much is left, and I appreciate that when I’m reading.
Another use of numbers I’ve seen is to offer a list of five things, but then to deliver six, and make a slight bit of humor out of that. Or even give a small prize to the first person to notice and mention it in the comments.
I like the video very much. I want to be like Grace Hopper when I grow up!
Last thought: Whenever did blogging stick to formal writing rules? Haha!
Grace Hopper is amazing, isn’t she? But so are you!
Interesting point on numbering lists where the order isn’t important. I think this is mainly a matter of style as the numbers in a list don’t represent facts. When I write a list post, I do number the subheads so that people know how far they’ve still got to go in the list and to make it clear I’m delivering on the promise of 5 tips (or 7 tips etc).
I once made a mistake and the numbering was wrong. I got called out quite quickly but didn’t think of awarding someone a price. Nice idea!
And I do agree with you … bloggers often take the freedom to interpret the rules their way and break them when they like. I do 🙂
I always taught my writing students to follow the rules as they are learning writing basics, but it is also okay to occasionally break a rule if they have a good reason to do so. This article provides a great example of when, how, and why to “break a rule” when writing. Also loved the little video you shared. Thanks for another great post!
Yes! As Picasso says: Learn the rules like a pro, so you can break them like an artist.
Thank you for stopping by 🙂
He is also known to have said “If I had joined the priesthood, I would have become a Pope, I took up painting and became a Picasso”.
I think it was his mother who said that to him?
I often wonder about the “less than 10” rule. This helps me understand why I’ve been frustrated and have started doing what looks best to me. Now I have permission…and the facts to back it up! 🙂 Thanks.
So, you were right all along! Glad to have cleared that up 🙂
Henneke:
Thanks for this perspective. You certainly clarified questions I have every time I write numbers in copy.
To write “%” or “percentage” is another sticking point!
Loved the nanosecond video. Can’t be beat “show and tell!”
I love that nanosecond video, too!
The simplest rule to follow for % vs percent is to follow a word with a word and a number with the symbol. So, two percent, but 2.2%.
I agree 100%. Numbers pop.
As for those style guides, enough said.
I see no reason why we cannot create a guide that expresses OUR STYLE 🙂
That’s the best thing I’ve heard this whole week … we can all create own guide to express our style. Fab! 🙂
Great article, Henneke! I stick to the words from one to nine then switch to digits, unless it’s a title. Digits are easier to spot and draw the eye in, whereas words do not – not as strongly. I would agree with odd numbers being more appealing too.
Being consistent in your approach is probably the main thing!
True – we will not please everyone. My mother was curious to learn – looked up information all the time; worked difficult crossword puzzles and word problems. That video clip “made me want to learn more” – here are 2 more takeaways about Grace Murray Hooper – quote “I’ve come to realize that there is no use doing anything unless you can communicate.” and after a moth infiltrated the circuits of Mark I, she coined the term bug to refer to unexplained computer failures.
I hadn’t heard of Grace Hopper before I saw that video clip, and I was also curious to learn more about her. I came across the story about debugging, but hadn’t come across her quote. Thank you for sharing, JoAnne, and for stopping by, of course!
You kicked my copywriting thought process into high gear Henneke! I had no idea the power of word numbers, number numbers, etc.
Thank you
Bert
You’re not the only one! I see a lot of people missing out on this one.
Thank you for stopping by, Bert 🙂
Darn good point made 🙂 Numbers make all the difference.
I am glad you agree ?
Thanks for an interesting look at how to use numbers Henneke. I always have to think 2 or 3 (or is it two or three?) times before deciding what format is best.
And where’d you find the Grace Hopper clip? What a wonderfully clear explanation of something unimaginable.
All the best from sunny Sydney.
Unfortunately, I can’t remember where I came across the Grace Hopper clip. I should have made a note. But when I saw it, I knew I had to include it some time. Despite the rather grainy recording, it’s fabulous.
You had me at the headline. Who would pass up the opportunity to find out the 1 tweak that would boost their credibility and persuasiveness? Not me!
I used to adhere to the APA style and write out numbers under 10, even though I could see that the actual numerals were more eye-catching in my text. I won’t be doing that any more ?
Thanks, Henneke.
I love it when a tip is so easy to both grasp and implement.
This might be the easiest tip on my whole website. I wish writing could always be so simple 🙂
I’m sure we all wish that.
On a different note, thanks for reminding me of Oliver Sacks the other day. I am now reading his memoir called “On the Move – A Life” and it is compelling. What a very honest and human person, who led a remarkable life, that is for sure.
I thought it was you who reminded me to read his essays! I recently read Gratitude, and started reading The River of Consciousness. Although quite different, they’re both excellent (as far as I’ve read). I loved his memoir On the Move, too.
Great stuff, Henneke. Really useful. Now I’m going to treat numbers with more respect.
I like that idea: treating numbers with respect.
Thank you for stopping by, Aleksei!
