The National Football League is the richest sports league in the world with 27 NFL teams landing on Forbes’ recent look at the 50 most valuable sports teams, including the Dallas Cowboys who ranked first at $4 billion. But when it comes to global reach, NFL teams can’t touch their brethren that play the other brand of football.

The NFL’s 32 teams have a combined 141 million followers on social media across Facebook, Instagram and Twitter. The tally lags Spanish soccer powerhouses Barcelona and Real Madrid, who on their own command 148 million and 146 million followers respectively. Real’s Cristiano Ronaldo and Barca’s Lionel Messi have the two biggest individual followings in sports with 215 million and 131 million as of last month.

A big following on social media is not everything though for sports teams. It is important to have an engaged audience to help expand the team’s brand and ultimately to monetize that audience. To see which sports teams were doing the best job on social media, Forbes turned to Hookit, which tracks sponsorship value in social and digital media.

Hookit examined the social media accounts of the teams in every major sports league to gauge followings, interactions (likes, shares, comments or retweets) and “earned media value.” The media value is based on sponsored promotions via hashtags and mentions and not image recognition. “Total follower numbers can be impressive, but the engagement is what drives the value coupled with the quality of ‘promoted’ posts,” says Hookit co-founder Scott Tilton.

We combined the ranks of teams in these three categories to determine the top sports teams on social media below. The stats cover June 2015 through June 2016. Soccer dominates the action with 11 of the top 20 teams. Barcelona ranked first in all three categories.
