What is viral content? Definition, examples and how it spreads

Viral is a piece of content, such as a video, post, meme or ad, that spreads quickly because people share it with each other on their own initiative. Reach grows from person to person, like a virus, instead of through paid media. The best-known example, the 2014 ALS Ice Bucket Challenge, raised $115 million for the ALS Association in eight weeks.

What does viral mean in marketing?

In marketing, viral means content whose reach comes mainly from shares, not from the brand’s own budget. One person shares it, several friends see it and share it further, and the audience multiplies in hours or days. Viral marketing is the deliberate attempt to create such content, and it is closely related to buzz marketing.

Where does the term viral marketing come from?

The term viral marketing became popular in 1996 and 1997. Jeffrey Rayport used it in the 1996 Fast Company article “The Virus of Marketing”, and media critic Douglas Rushkoff wrote about “media viruses” in the same year. In 1997 investors Tim Draper and Steve Jurvetson used the phrase to describe Hotmail, which added a sign-up link to every outgoing email and gained 12 million users in 18 months.

Why does content go viral? The STEPPS model

Content goes viral when it gives people a reason to share that benefits the sharer. Jonah Berger, a marketing professor at the Wharton School, describes 6 drivers in his 2013 book “Contagious”, known as STEPPS:

  • Social currency: sharing makes the person look smart, funny or in the know.
  • Triggers: everyday cues keep the idea top of mind.
  • Emotion: strong feelings such as awe, amusement or anger drive action.
  • Public: visible behaviour gets copied.
  • Practical value: useful tips get passed on.
  • Stories: the message travels inside a narrative.

Berger also points out that only about 7% of word of mouth happens online, so a viral idea often spreads in conversations too.

Viral content on TikTok, Reels and in search

Today virality happens mostly in recommendation feeds. TikTok and Instagram Reels show videos to people who do not follow the creator, so one strong clip can reach millions without an existing audience.

For SEO, a viral moment creates a short spike in branded searches, mentions and links. In my projects I make sure a landing page and a press page are ready, because journalists and bloggers who cover the story give natural backlinks. Those mentions also help AI search engines recognise the brand as an entity.

How to plan for virality

Nobody can guarantee virality, but you can raise the odds with a repeatable process:

  1. Pick one emotion and one simple idea.
  2. Make the first 2 seconds of a video work without sound.
  3. Add an easy action people can copy, such as a challenge or template.
  4. Test several short versions instead of one expensive film.
  5. Prepare landing pages and SEO tracking before launch.
Pro tip: Treat virality as a bonus, not a strategy. Plan content that works for your target audience even at 1,000 views, and give every piece a clear next step, so a sudden spike turns into leads instead of empty reach.
