I’m not exactly sure when sentence case vs capitalising the first letter of every word in a heading became the norm, but I suspect it started when people began using AI to create their content.
In case you don’t know what on earth I’m talking about, it’s when a heading looks like this:
Every Word In A Heading Starts With A Capital Letter
As I understand it, this style of capitalisation, often called start case, has roots in computing and programming conventions, so it makes sense that it crept in with the increased use of AI.
And I say it crept in, more like swept in, because it’s everywhere, like a fashion trend I didn’t get the memo about (not that I’m exactly what you’d call a follower of fashion).
But what really doesn’t make sense to me is why so many people have adopted it.
Not only does it look odd (to me, anyway), but I’d argue that it makes headings less easy to read, too.
And when we’re creating content we want people to read, surely we want to make our message as easy to read as possible?
Sentence case vs capitalising every word: what’s the difference?
If you’ve ever wondered whether you should capitalise every word in a heading, it helps to understand the main styles of capitalisation.
There are three worth knowing about.
1. Sentence case
Sentence case means capitalising the first word of a heading, along with any proper nouns that require capital letters.
For example:
The importance of getting the basics in marketing right
This is my preferred style because it looks clean and reads naturally.
2. Title case
Title case means capitalising the main words in a heading, while leaving certain shorter words in lowercase.
For example:
The Importance of Getting the Basics in Marketing Right
Title case is perfectly legitimate. It’s widely used in publishing and can work well in certain contexts.
It’s just not my preference.
3. Start case
Start case takes the approach of capitalising every word, including short connecting words.
For example:
The Importance Of Getting The Basics In Marketing Right
This is the newest kid on the block.
Does capitalising every word make content harder to read?
I’m not claiming to have conducted a scientific study into heading capitalisation, and therefore I can’t claim that everyone will find start case harder to read.
People have different preferences, and familiarity plays a part in how we respond to written content.
However, there is a good reason to think about the visual presentation of words.
We don’t read by carefully examining each individual letter. We recognise familiar word patterns, use context, and move through text to understand its meaning.
Capitalising every word changes the visual appearance of a heading. It introduces more uppercase letters, including short words that would normally appear in lowercase.
For me, this interrupts the natural flow.
And that matters.
Your headings should help people scan a page, understand what each section is about, and decide whether the content is relevant to them.
They shouldn’t make your reader work harder than necessary.
And not making your reader work hard in general is good advice when it comes to any form of written communication.
That’s why things like sentence length, spacing, punctuation, and how you use capital letters in headings matter.
But could heading capitalisation affect SEO?
If you’re writing blog posts, updating website pages, or managing content for a business, you might worry that this has become a trend because it has a positive effect on SEO.
The good news is that there’s no established SEO advantage to capitalising every word in a heading.
Google’s guidance focuses on creating helpful, reliable, people-first content.
So what matters much more is whether your content answers the reader’s question, uses relevant terminology naturally, provides useful information, and delivers a good user experience, of which readability plays a part.
What about AI search?
With more of us thinking about AI search, it’s tempting to scrutinise every little detail of how our content is written and formatted, wondering whether it will make a difference to our chances of appearing in AI-generated search results.
But, as with SEO, there’s no evidence to suggest that not using start case will stop your content from appearing in search results. Equally, there’s no evidence to suggest that using it will improve your chances.
Just because AI suggests it doesn’t mean you should use it
I’m not anti-AI. Far from it.
AI can be a useful tool for brainstorming ideas, developing outlines, summarising information, and generally helping with the writing process.
But there’s a difference between using AI to support your work and accepting everything it produces without question.
If you use AI to draft a blog post, you still need to review it. Does it sound like your business? Is the information accurate? Is the language appropriate for your audience? Does it say anything useful? Does it follow your brand guidelines?
And, yes, does it use the right capitalisation?
AI-generated content can look polished while still missing the mark. It can be grammatically correct without being particularly engaging. It can follow a familiar format without that format being right for your audience.
That’s why the human touch matters.
How to choose the right capitalisation style for your content
If you’re reviewing your website or creating content guidelines for your business, here are a few simple things to consider.
Choose a style that suits your brand. Think about how you want your business to communicate. A straightforward, conversational brand might find sentence case a more natural fit.
Make readability a priority. Your headings should help your readers understand your content and navigate the page. Avoid unnecessary formatting that distracts from your message.
Be consistent. Pick a style and use it consistently across your website, blog posts, email marketing, and other marketing channels.
Don’t confuse formatting with SEO. Capitalising every word won’t magically improve your search rankings. Focus on useful content, clear headings, and answering your audience’s questions.
Check your AI-generated content. If you use AI to help create content, make sure the finished version follows your preferred style rather than simply accepting the default.
A small detail, but part of a bigger picture
I appreciate that heading capitalisation isn’t the biggest challenge facing businesses when it comes to marketing.
There are far more important things to get right, from understanding your audience and explaining why they should choose you to making sure your website turns visitors into enquiries.
But small details do matter.
Marketing is about communication. And good communication means thinking about the person on the receiving end of your message.
It means making your content clear, useful, and easy to engage with, rather than simply following whatever happens to be popular at the time.
Perhaps start case will become the accepted standard. Language and writing conventions evolve, and I’m not suggesting that there’s only one correct way to format a heading.
But I do think it’s worth questioning why we make certain choices, particularly when they appear to be driven by a tool rather than a conscious decision about what works best.
So, if you’ve been wondering whether you should capitalise every word in your headings because that’s what AI seems to do, here’s my advice.
Don’t feel you have to.
When it comes to sentence case vs capitalising every word, I’m sticking with sentence case. And if you want people to read and engage with your content, I’d suggest giving it a go, too.
