5 reasons why a headline goes viral

A headline might be a reader’s first – and only – contact with a brand, and many will keep skimming until they land on something that takes their interest.

If you aren’t into the nitty-gritty of headlines, stop reading now. But if you want to be that content creator who writes the runaway headline, here’s a snapshot of what some of the research has found.

Between 1 March and 10 May 2017, BuzzSumo analysed 100 million of the most shared article headlines on Facebook and Twitter, the platforms dominated by publisher and consumer content. Then in July, it published its analysis of 10 million B2B headlines – those shared on LinkedIn – and found that the best headline phrases, structures, numbers and lengths differed from the B2C results.

1. What works for B2C content

While previous research suggested that the first three and last three words were the important parts of a headline, the BuzzSumo research highlighted linking phrases as key for headlines targeting B2C audiences.

The three-word phrase – or trigram – that led the engagement charge (likes, shares, comments) was ‘will make you’. In fact, on Facebook it had twice as many engagements as the trigram that took second place (‘this is why’), followed by ‘can we guess’, ‘only X in’ and ‘the reason is’.

BuzzSumo determined that the success of the ‘will make you’ phrase was based on it linking content to the emotional impact it will have on the reader – it sets you up to care (‘will make you cry’, ‘will make you smarter’, etc.).

It also found that headlines that provoke curiosity work well when readers are looking to learn something from an article. They are a little like the ‘will make you’ articles, but they tell you what you’ll find out rather than what you’ll feel.

The BuzzSumo research found that the top five phrases starting a B2C headline were:

  1. X reasons why…
  2. X things you…
  3. This is what…
  4. This is the…
  5. This is how…

The top five phrases ending a B2C headline were:

  1. …the world
  2. …X years
  3. …goes viral
  4. …to know
  5. …X days

Admittedly, the second-place holder might not rate as well in Australia, but the five top-performing first words were:

  1. This…
  2. Trump…
  3. How…
  4. 10…
  5. Why…

So, what doesn’t work for B2C audiences? The five worst-performing frequently used phrases were:

  1. control of your
  2. your own business
  3. work for you
  4. the introduction of
  5. what’s new in

Confirming earlier Outbrain research, BuzzSumo found that 12 to 18 words and 80 to 95 characters had the highest engagement on Facebook.

2. What works for B2B content

In BuzzSumo’s analysis of 10 million headlines of articles shared on LinkedIn, the practical and informative nature of how-to and list posts (see #3 below) proved to be strong performers in the top five most popular three-word phrases:

  1. X ways to…
  2. The future of…
  3. X things you…
  4. How to get…
  5. How to make…

There was a clear frontrunner in the top two-word phrases starting headlines – ‘How to…’ was shared almost three times more on average than the second-place holder. The top two-word phrases starting B2B headings were:

  1. How to…
  2. The X…
  3. X things…
  4. X ways…
  5. Top X…

Note that after the ‘How to…’ phrase, the next four most shared phrases were all forms of list posts, which gained more than double the average shares of ‘what’ or ‘why’ posts.

Celebrity brand names also garnered high levels of engagement. It makes sense that companies influencing the business environment and forging technological and business model innovation – like Uber, Google, Apple, Facebook, Tesla and Amazon – will have strong reader appeal. For example, nib’s Ambulance or Uber: Who you gonna call?generated a lot of conversation on its Facebook page due to Uber’s topicality.

At seven to 12 words, the optimum headline length for LinkedIn is much shorter than for Facebook.

3. The ongoing power of the list

In July 2017, CoSchedule founder Garrett Moon published results of an analysis that began with close to one million blog headlines – which were then put through various filters. The top takeaway was that list posts or listicles (headlines that start with a number) are “huge”. Moon wrote they are “the most likely type of post to be shared 1000 or even 100 times”. Interestingly, he also noted that “list posts only made up 5% of the total posts actually written”.

The BuzzSumo research, confirming the power of lists and the list post format, found the six most effective numbers (in descending order) in B2C content are 10, 5, 15, 7, 20 and 6. In B2B content, the most shared numbers that start post headlines are 5, 10, 3, 7, 4 and 6, with 5 and 10 performing equally well. Note that how-to posts outstripped list posts in B2B.

CoSchedule’s results show that list posts that they identified by the words ‘thing’, ‘should’ and ‘reasons’ – ‘5 things you can do…’, ‘4 reasons why you should…’ – do best on Facebook, Twitter and LinkedIn.

It’s possible that this is due to a combination of clear promise (‘10 steps’, etc.) and the scannable nature of the post, where you can easily work out which bits you want to read.

4. Emotion is good but beware the bait

While strong emotional headlines and those provoking curiosity may get you results, you need to rein in any urge to overstate.

In May 2017, Facebook announced it would demote “headlines that exaggerate the details of a story with sensational language” and those that aim “to make the story seem like a bigger deal than it really is.”

There may be some debate about what is and isn’t clickbait, but there are two key points to consider. In the first place, the reader needs to feel encouraged to read. And in the second, they need to not be disappointed when they have finished reading.

5. Research, tailor and test

There are no hard and fast rules. You always need to research what works for your audience, your topics and your social platforms, and to test your headlines. Different audiences will require different content and will be accessing it on different platforms. For example, Outbrain works for an editorial-led audience more than a business-specific audience.

In the interests of transparency, this headline isn’t the first that came to mind. It’s the result of trawling through this research.

Maybe we all need to take the advice of Ann Handley, chief content officer at MarketingProfs: “Spend as much time writing the headline as you do an entire blog post or social post.”

If there’s one topic Australians never tire of debating, it’s housing. Whether it’s at the pub, around the dinner table, or dominating headlines, property prices, rent hikes and the “can I ever afford a home?” questions are constant fixtures of the national conversation.

But let’s be honest—rising house prices aren’t new. What is changing is how the conversation is evolving, who’s shaping it, and which narratives are starting to stick.

 Using Lumina’s Stories and Perspectives, we analysed 19 stories and over 50 perspectives across a 30-day period from 15 March to 14 April 2026 to understand what’s actually driving the housing narrative in Australia right now—and why it matters. 

 

Which are the stories shaping conversation and who's driving it?

 

 

Housing Supply and Affordability Divide — Analysts and economists link supply shortages directly to soaring prices. Cities that built more homes saw far less price growth. 

Key drivers: Gerard Burg (Cotality), Peter Tulip (Centre for Independent Studies), Australian Associated Press

Tax Reform Debates Heat Up Ahead of Budget — 14 competing perspectives. Advocates say reforms are essential for fairness; the property industry warns they’ll push rents up 30%. 

Key drivers: Anthony Albanese, Jim Chalmers, Angus Taylor, Housing Industry Association, Saul Eslake

Grattan Institute Connects Housing to Democratic Trust — A major report argues that the housing crisis is eroding public confidence in democracy itself. 

Key drivers: Aruna Sathanapally, Grattan Institute

 

 

Australians make housing supply the biggest story


This perspective was
100% of the coverage of this story and generated 85 media items, making it the most widely covered story of the entire period. The main insight is the public drawing a direct line between housing supply levels and property prices across Australia’s capital cities. 

Perth and Brisbane, where home construction has lagged well behind population growth since the pandemic, have seen property values surge massively. Meanwhile, Victoria — which built a proportionally higher number of new homes — saw less growth, compared to the national average.

It ran everywhere from PerthNow to regional papers across NSW and Victoria. The fact that the Australian Associated Press syndicated the data meant it hit dozens of outlets simultaneously.

 

[/et_pb_text][et_pb_image src="https://www.isentia.com/wp-content/uploads/2026/04/2-1-scaled.png" title_text="2" _builder_version="4.27.4" _module_preset="default" width="68%" max_width="68%" module_alignment="center" custom_margin="||60px|||" global_colors_info="{}"][/et_pb_image][et_pb_text _builder_version="4.27.4" _module_preset="default" text_font="DM Sans||||||||" header_font="DM Sans||||||||" header_3_font="DM Sans|700|||||||" global_colors_info="{}"]

The key drivers are property analysts Gerard Burg from Cotality and Peter Tulip from the Centre for Independent Studies. Both are pushing the same message. If you want to fix affordability, you have to fix supply. Their proposed solution is liberalising zoning laws, particularly in NSW and Victoria, to allow more homes to be built faster. 

 

Why does this matter for communicators?

This story had the widest media footprint of the entire period, reaching outlets from The West Australian to regional mastheads across the country. If your organisation operates in housing, property, or urban planning, the “supply-equals-affordability” narrative is now firmly established in public discourse, and therefore, your messaging needs to account for it. Audiences know of the supply argument before, and with experts aligned on the issue, it’s harder for policymakers to dismiss it easily. 

It’s also worth noting how the analysis around who the key drivers are adds a layer traditional media monitoring might miss. The AAP’s role as the primary distribution channel meant this story reached dozens of the bigger mastheads like PerthNow and The West Australian  and  hyperlocal outlets like the Cobram Courier and Benalla Ensign, simultaneously. For communicators, this distribution pattern indicates that a story has penetrated both metropolitan and regional audiences, making it impossible to dismiss as just a capital-city concern.  

 

Tax reform rebates are the most contested story of the month

The housing tax reform debate was the most contested generating 14 distinct perspectives across 23 media items becoming by far the most multi-sided story of the month. However, the top three perspectives were the most interesting to look at considering how disputed the opinions of either side are and sit at the highest level in the government. 

At the centre of it is the Albanese Government’s consideration of reducing the capital gains tax discount and limiting negative gearing ahead of the May budget. The country is essentially split down the middle on this one. 

Perspective 1: This made up for 34.8% of the story coverage. Prime Minister Anthony Albanese, Treasurer Jim Chalmers, and housing advocacy group Everybody’s Home are arguing that the current system unfairly benefits wealthy investors while locking out first-home buyers. Economist Saul Eslake backs this view. Together, they account for about a third of the story’s total coverage.

Perspective 2: This had an equal share in coverage at 34.8% of the story. Opposition figures Angus Taylor, the Housing Industry Association, and Victorian Libertarian Party Leader David Limbrick are warning that scrapping these tax incentives will scare off investors, shrink rental supply, and push rents up by as much as 30%. They command an equal share of the conversation (Herald Sun)

[/et_pb_text][et_pb_image src="https://www.isentia.com/wp-content/uploads/2026/04/image-11.png" title_text="image" _builder_version="4.27.4" _module_preset="default" width="60%" max_width="60%" module_alignment="center" custom_margin="||72px|||" global_colors_info="{}"][/et_pb_image][et_pb_text _builder_version="4.27.4" _module_preset="default" text_font="DM Sans||||||||" header_font="DM Sans|700|||||||" header_3_font="DM Sans|700|||||||" global_colors_info="{}"]

What’s interesting is what sits beneath these two dominant perspectives. A third angle that was 17.4% of the story coverage  was driven by Chalmers and Greens Senator Nick McKim, frames the whole debate as a question of intergenerational fairness. And then there are the young “rentvestors” who rent where they live but own an investment property elsewhere. They’re worried about getting caught in the crossfire of changes that weren’t designed with them in mind (Australian Financial Review)

Trust is eroding in the Australian democracy — and housing is the problem

The Grattan Institute released a report warning that trust in Australian democracy is under pressure, and housing is one of the reasons why. This soon became the second biggest story, generating 58 media items. 

Led by Grattan CEO Aruna Sathanapally, the report argues that persistent inequality, including the housing affordability gap, is eroding the social contract between citizens and government. The report explicitly names the housing crisis as one of the major unresolved challenges fuelling public disillusionment. Sathanapally is the key driver of this story, commanding over 93% of its coverage. Her influence matters because she’s reframing housing as something bigger than an economic problem. She’s positioning it as a threat to democratic stability. That’s a powerful narrative shift, and one that gives housing advocates a new way to make their case. 

For anyone in public affairs or government communications, this connection between housing and democratic trust is worth watching. It’s the kind of framing that can reshape how policymakers prioritise the issue. 

[/et_pb_text][et_pb_image src="https://www.isentia.com/wp-content/uploads/2026/04/image-9.png" title_text="image" _builder_version="4.27.4" _module_preset="default" width="60%" max_width="60%" module_alignment="center" custom_margin="||92px|||" global_colors_info="{}"][/et_pb_image][et_pb_text _builder_version="4.27.4" _module_preset="default" text_font="DM Sans||||||||" header_font="DM Sans|700|||||||" header_3_font="DM Sans|700|||||||" min_height="763px" global_colors_info="{}"]

How does this inform PR & Comms strategy?

  1. Know which side of the debate your audience sits on: The tax reform story alone has 14 perspectives. If you’re crafting messaging around housing policy, understand which perspective your stakeholders identify with and who they consider a credible voice. A one-size-fits all approach might not work.
  2. Follow the key drivers, not just the headlines: The unexpected pairing of Greens Senator Nick McKim with Treasurer Chalmers on intergenerational fairness suggests this issue is cutting across traditional party lines in ways that could reshape coalition dynamics. Meanwhile, the "rentvestor" audience represents a politically orphaned group that neither side of the debate is referencing or considering, making them a potential swing audience whose concerns could quietly shape how any reform actually lands.
  3. Watch the emerging narratives: One Nation’s growing support, the “rentvestor” demographic, and the connection between housing and democratic trust are all stories that could become dominant in the months ahead. 

 

What does this tell us about the Australian housing conversation?

It’s not a new crisis anymore. It’s a nationally entrenched issue that is now being addressed by the public by way of debates along with policymakers and experts at the highest government level. These debates are on solutions, trade-offs and fairness. The conversation is much more sophisticated where audiences are not just talking about “prices being too high”, but discussing supply, investments, short term relief vs long term reform. What’s also essential is to look at the key drivers or the key voices driving the top narratives.  From economists to policymakers to advocacy groups, the voices gaining traction are influencing how the issue is understood and what solutions feel viable.

Understanding not just what’s being said, but who is driving the conversation and why it’s resonating, is becoming critical for organisations looking to engage credibly. That’s where Lumina’s Stories and Perspectives comes in, helping you move beyond headlines to uncover the narratives and voices shaping the issues that matter most.

The media landscape is accelerating. In an era where influence is ephemeral and every angle demands instant comprehension, PR and communications professionals require more than generic technology—they need intelligence engineered for their specific challenges.

Isentia is proud to introduce Lumina, a groundbreaking suite of intelligent AI tools. Lumina has been trained from the ground up on the complex workflows and realities of modern communications and public affairs. It is explicitly designed to shift professionals from passive media monitoring back into the role of strategic leaders and pacesetters. 

“The PR, Comms and Public Affairs sectors have been experimenting with AI, but most tools have not been built with their real challenges in mind.” said Joanna Arnold, CEO of Pulsar Group

“Lumina is different; it is the first intelligence suite designed around how narratives actually form today, combining human credibility signals with machine-level analysis. It helps teams understand how stories evolve, filter out noise and respond with context and confidence to crises and opportunities.”

Setting a new standard for PR intelligence

Lumina is centered on empowering, not replacing, the human element of communications strategy. This suite is purpose-built to help PR, Comms, and Public Affairs professionals significantly improve productivity, enhance message clarity, and facilitate early risk detection.

Lumina enables communicators to:

  • Understand & Interpret: Move beyond basic alerts to strategically map the trajectory and spread of narrative evolution.
  • Focus & Personalise: Achieve the clarity necessary to execute strategic action before critical moments pass.
  • Execute & Monitor: Rapidly deploy strategy firmly rooted in real-time, actionable insight.

Get a demo today: Stories & Perspectives module

We are launching the Lumina suite by making our first module immediately available: Stories & Perspectives.

In the current fragmented, multi-channel media environment, communications professionals need to be able to instantly perceive not just how a story is growing, but also how it is being perceived across different stakeholder groups.

Stories & Perspectives organizes raw media mentions into clustered, cohesive Stories, and the Perspectives that exist within each, reflecting distinct media, audience, and public affairs angles. This unique functionality allows users to:

  • Rise above the noise: Instantly identify which high-level topics are gaining momentum or fading from attention.
  • Get to the detail, fast: Uncover the influential voices, niche communities, and specific channels actively shaping the narrative.
  • Catch the pivot point: Precisely identify the moment a story shifts—from a strategic opportunity to a reputation risk—or when a new key opinion former begins guiding the conversation.

"Media isn’t a stream of mentions," said Kyle Lindsay, Head of Product at Pulsar Group. "But rather a living system of stories shaped by competing perspectives. When you can see those structures clearly, you gain the ability to understand issues as they form, anticipate how they’ll evolve, and act with precision. That’s what we mean when we talk about AI built for communicators, and that's what an off-the-shelf LLM can't give you."

The Lumina Roadmap: AI tools for the future of comms

The launch of Stories & Perspectives is the first release of many. Over the upcoming months, we will systematically roll out the full Lumina roadmap, introducing a comprehensive set of AI tools engineered to handle every phase of the communications lifecycle.

The full Lumina suite will soon incorporate:

  • Curated media summaries: AI-driven daily summaries customized specifically to the priorities of senior leadership, highlighting only the most relevant stories.
  • Reputation analysis: Advanced measurement tracking how critical themes like ethics, innovation, and leadership are statistically shaping corporate perception.
  • Press release & media relations assistant: Tools designed to accelerate content creation and craft hyper-focused, personalized pitches that reach the precise contacts faster.
  • Predictive intelligence layer: Technology engineered to track and anticipate story momentum and strategic change before the window of opportunity closes.
  • Intelligent agents: Background agents continuously scanning all media channels for emerging key spokespeople and previously undetected reputation risks.
  • Enhanced audio, broadcast & crisis detection: Complete, real-time oversight of all channels—including audio and broadcast—enabling rapid context building and optimal crisis response delivery.
