Donald Trump has 55 million followers on Twitter $TWTR. But his tweets reach less than half of that, according to an analysis by SparkToro.
More than 60% of the US president’s Twitter following, or about 33 million accounts, have been deemed fake by the marketing software firm. It ran all of Trump’s followers through a machine-learning based tool that picks up signals that an account might be spam, propaganda, a bot, or inactive. If the account racks up seven to 10 signals or more, it was counted as fake.

What counts as a signal? Here are some that SparkToro’s tool registered for Trump’s followers:
Here’s how SparkToro’s founder, former Moz chief executive Rand Fishkin, explains the rationale behind the analysis:
I have this sinking feeling that someone will undoubtedly point to one of these signals and say “but that doesn’t mean the account is spam/bot/propaganda/inactive!” so let me state this again: no one, two, three, or even six signals means we’ll treat an account as low quality. But, I think we’d all agree (and the machine learning model built off spam+bot accounts would concur) that it’s very rare that an account could have a combination of 7-10+ of the above signals and still be a real, active, human being regularly logging into their Twitter account. Not impossible, just exceptionally unlikely.
SparkToro also looked at the following of other prominent US politicians. Though Trump has the highest share of fake followers by far in the sample, it’s a problem that spans geographies and party lines. Here are the results:
The data offer a reality check for politicians, but they’re not necessarily a reflection of their reach online, SparkToro points out, particularly in the case of the president. While Trump may only be reaching 25 million human-run Twitter accounts, he can count on the media and others to spread his tweets to a much broader group.
