There was a time when hashtags were a key tool for positioning yourself on social media, but everything is changing, and these hashtags have lost much of their power. This, coupled with an attempt to "clean up" post descriptions, has led several platforms to recommend limiting their use or even enforce it outright. The latest to do so is TikTok. The famous Chinese social network has decided to establish a maximum of five hashtags per post. In recent days, its users have seen a pop-up notification informing them of this change while putting the finishing touches on their TikToks. This would be a way to improve the social media experience by reducing hashtag spam, achieving posts with less chaotic descriptions, and helping people discover more organized and focused content. Hashtags no longer control reach on social media. This measure is nothing revolutionary, as much as it may cause some annoyance to those accustomed to flooding their TikToks with hashtags. In recent years, these tags have lost relevance when it comes to segmenting content, and fewer and fewer people are searching by hashtag. Back in 2022, Adam Mosseri explained that hashtags had little real use in increasing views on Instagram. The evolution of algorithms, along with the growing power of key metrics such as impressions, views, and shares, have changed the game, and now reach is no longer subject to the use of hashtags containing keywords. Another notable case is Twitter, which on June 27th initiated a much more radical measure: eliminating the use of hashtags in its ads. Musk himself called them an "aesthetic nightmare" and asserted that they are useless on his social network. Of course, this doesn't mean you should abandon their use on TikTok, as they continue to be useful for organizing content. What we do recommend is that you focus on things like using keywords in your descriptions, selecting trending topics, using audio and music, and encouraging engagement with your content. Likewise, a good way to design your strategy is to use TikTok's trends section. In any case, it's always interesting to know which hashtags are the most popular worldwide on Instagram, TikTok, and LinkedIn.
