Facebook and Twitter’s growth challengeReading Time: 6 minutes
Facebook and Twitter are at different points in their histories: Facebook just celebrated its 10th anniversary, generates profits each quarter, and has become a dominant force in global social networking, while Twitter has a fraction of Facebook’s users, loses money and seems to suffer from a crisis of identity about its role in the world. But the two companies share a common path to growth, and it’s instructive to look at where each of them is on that path.
Fundamentally, both companies need to do three things: grow users, get their users more engaged, and then find ways to monetize that engagement. Twitter actually makes this pretty explicit, but both companies provide metrics that allow us to measure how they’re doing on each of these three strategic objectives.
User growth has peaked at both companies
First, user growth. The chart below shows the growth in the number of monthly active users (MAUs) year on year at both companies, as reported by each of them.
As context for Twitter’s current scale, here’s a chart that shows user numbers for various other popular services:
Twitter is shown in light blue, and although it’s recently passed Amazon’s number of active user accounts, it’s far behind Apple’s iTunes and iCloud user numbers, and just barely ahead of the number of Dropbox accounts, which is also growing more rapidly. If Twitter is going to be a mass-market phenomenon globally it needs to both grow significantly more quickly and achieve significantly greater scale.
Twitter talks explicitly about engagement, and uses timeline views per MAU as its chief measure of engagement. Facebook doesn’t talk about it in quite the same way, but it does provide regular reporting on its daily active users, which are a good proxy for the proportion of users who are actively engaged. The chart below shows these engagement metrics for Twitter and Facebook. The first chart shows timeline views per MAU for Twitter, while the second shows the percentage of MAUs who are also daily active users at Facebook.
The good news for both companies is that these metrics are very much heading in the right direction. The exception is the most recent quarter for Twitter, where timeline views per MAU actually fell, but this was the result of tweaks to the Twitter mobile apps, which led to less going back-and-forth to and from the timeline, depressing overall numbers[ref]See Dick Costolo’s remarks on the earnings call[/ref]. So it’s a one-time downward adjustment of the curve rather than a sign of a longer-term downward trend.
Overall, though, both companies are successfully increasing engagement, which means that there is at least one driver of growth even as user growth slows. However, Facebook’s engagement growth is slowing in the US, its dominant region, which is likely a sign that it is reaching saturation among its existing base, so it’s not all rosy.
Both companies’ revenue is directly tied to advertising, which is another way of saying that they both have to find ways of monetizing the user growth and related growth in engagement in order to grow revenues. So the third lever for growth is increasing the amount of revenue per user, which is shown in the next chart:
The first obvious thing is that Facebook’s ad revenue per user is much higher, which of course reflects its greater maturity and experience in providing advertising to users. But both are rising in a healthy way, which is helping to drive overall revenue growth when combined with user growth and user engagement. Interestingly, though, both companies do far better at monetizing their US users than they do international users:
This is particularly dramatic for Twitter, which generated just 23 cents per MAU in the fourth quarter outside of the US, compared with over two dollars per MAU in the US. Facebook sees a greater spread between its various regions, with the US generating over $5 per quarter per MAU, Europe at $2.36 in Q4, and its other regions at under a dollar per quarter per MAU. Again, the good news though is that each company is successfully growing revenue per user.
The other thing worth thinking about in this context is what’s possible longer-term. Unlike other forms of revenue generation, advertising has a natural saturation point at which it becomes off-putting to users, which puts a cap on revenues per user. The revenues per user in the US of Google and Yahoo, long-established US-based online advertising businesses, are vastly different, and show the range of what’s possible. For this exercise, I’ve used Comscore’s numbers for desktop unique users for both Yahoo and Google sites as a good proxy for their number of US users. It obviously excludes mobile users, but my guess would be that neither number would rise dramatically if mobile-only users were factored in since the total numbers are both so close to the size of the US online population. The chart below shows US revenue per US user (using that Comscore data) over the last few quarters for Google and Yahoo[ref]Yahoo hasn’t reported its US revenue numbers for Q4 2013 yet[/ref]:
Google clearly generates enormously more from its US users than Yahoo does at over $30 per quarter. Yahoo, on the other hand, generates just over $4 per quarter from its US users. Facebook has already passed that amount, and Twitter is about halfway there at this point. But neither is anywhere near catching Google yet. This obviously tells us a lot about Yahoo’s struggles too: applying the same growth strategy framework to Yahoo suggests that it’s maxed out user numbers in the US and it’s engagement and monetization where it needs to make significant progress. The big challenge here is that Google has long since hit upon the holy grail in online advertising: search. Search is unique in that it pairs advertisers with users who have expressed an explicit current interest in the item being advertised, resulting in very high hit rates. By contrast, Facebook and Twitter can only hope to derive enough about their users’ general interests to offer up profile-based targeting, which is inherently less effective (though it may help explain Facebook’s interest in graph search and other forms of search). See this separate post on advertising business models for more on this.
The other thing that’s worth noting is that Google still generates a large proportion of its overall revenues from the US, even though its overall user base is obviously much larger in the rest of the world. This suggests that even mature online advertising businesses will always see much higher average revenues per user in the US than in the rest of the world, and it’s not just a question of a lag as with engagement. This is another important factor for Facebook in particular to bear in mind as its growth in the US slows to a crawl.
So where do we stand in evaluating Facebook and Twitter’s growth challenges? Both companies have stopped growing their user bases as fast as they once did, though Facebook has hit that point with about a billion more users than Twitter and is still adding about a quarter billion each year. Twitter’s slowing growth is worrying and should be a major priority for the management to fix. However, both companies are successfully finding ways to get their users to spend more time on their services, which combined with increased efforts to develop effective advertising products has led to significant growth in revenue per user. Both companies could continue to grow revenue significantly in the coming years even with slowing user growth simply by growing engagement and revenue per user, though at some point both companies will hit up against the natural limits imposed by advertising based business models.
