Should You Still Use Hashtags on Social Media?

Performance Communications | March 11, 2025

This question comes up a lot when discussing social media strategy: Should we include hashtags?

The Origins of Hashtags

Hashtags were originally designed to group conversations on social platforms, making it easier for people to follow specific topics. If you were into motorcycles, searching for #Motorcycles would bring up relevant discussions.

They were a simple yet effective solution—until marketers got involved. Suddenly, everything needed a hashtag, and not always for the right reasons. (Lest we forget Susan Boyle and her, ahem, album party.)

The Decline of Hashtags

As brands and users started stuffing posts with excessive hashtags in an attempt to game the algorithm, the feature lost much of its original purpose. Instead of improving content discovery, hashtags often cluttered posts, making them look desperate rather than strategic.

For a while, many in the industry suspected that hashtags had little to no impact on brand engagement. That notion was reinforced by Adam Mosseri, CEO of Instagram, who stated that hashtags do not significantly influence content distribution or interaction. He made it clear: there’s no magic trick or algorithm hack that guarantees success.

Testing the Impact of Hashtags

We wanted to test that, so we worked with our client Michelin to put this theory to the test. In January, they experimented:

First half of the month → Posts included hashtags.
Second half of the month → Hashtags were removed.

The results? Hashtags still have some value—just not as much as you might think.

On Facebook and X (formerly Twitter), reach and engagement were either unaffected or saw a slight increase with hashtags.
On Instagram, reach remained the same, but engagement was slightly higher with hashtags.

The Verdict: Should You Use Hashtags?

So, what does this tell us? Well, it’s an unscientific test with inconclusive results—hardly a definitive answer.

However, my advice to clients remains the same: use hashtags sparingly and with purpose. They should serve as keywords to highlight relevant topics, not as a desperate attempt to game the algorithm.

At the end of the day, compelling content and genuine engagement will always outperform a post overloaded with hashtags.

TO CHARGE FOR FEATURES, OR NOT TO CHARGE? THAT IS THE QUESTION FOR SOFTWARE DEFINED VEHICLES

I enjoyed my first visit to FT Future of the Car summit last month, and it got me thinking. While Software Defined Vehicles (SDVs) and connected cars were a hot topic, communicating the benefits of these vehicles to consumers isn’t necessarily straightforward. It’s especially hard when it feels like new tech is simply the enabler […]

PARTNERSHIPS, PARTNERSHIPS, PARTNERSHIPS

Sam Mercer noticed a running theme at the FT Future of the Car Summit as the complexity and cost of producing modern cars is pushing more and more companies to work together. “Protectionism doesn’t work”. That was the clear statement from one panellist at FT Future of the Car last week. And this sentiment truly […]

Breaking Barriers

It’s not often you stop and stand in awe of sporting achievement, but Sunday morning’s London Marathon stopped me in my tracks. The sub two-hour barrier for a marathon was never meant to be beaten in competition across 26.2 miles. While Red Bull and INEOS’ 2019 event showed it could be done in controlled conditions, […]

2026 is make-or-break for self-driving cars in the UK

We all know that driverless cars are no longer the stuff of science fiction. While both China and the US have embraced autonomous technology, Aisling Fitzgerald looks at why 2026 promises to be a big year for self-driving vehicles here in the UK… This year is set to be a turning point for autonomous mobility […]

Do e-axles hold the key to the EV transition? Why EV powertrains are going all-in-one

While battery technology typically takes the role of frontman in the rock band that is the EV transition, Matthew Kirtley looks at another member of the group that could be about to take centre stage… According to a recent report from Automotive IQ, the total value of EV powertrains produced worldwide is projected to more than […]

The law of unintended consequences: The new per-mile EV tax in detail

It has been more than a week since the later-than-usual Autumn Budget, and we think the new proposals could have an unintended consequence that will bring an age-old challenge for the auto industry back in the spotlight. The 2025 Autumn Budget has introduced a new per-mile road tax for battery EVs and plug-in hybrid EVs. […]

5 key takeaways from the IAA Mobility show

We were on the ground at the IAA Mobility show earlier this week, and what a show it was. The European motorshow is back with a bang. Here are my five key take-aways: Rise of the small EV: Favourable market conditions and demand for low-cost EVs, lead to an abundance of great-looking all-electric hatchbacks. VW’s […]

Nuclear’s Role in the EV transition

It’s no secret that mass adoption of BEVs and PHEVs depends on access to reliable charging infrastructure, but an under-appreciated aspect of the EV revolution is how much it depends on affordable electricity. Here, Performance Communications’ own Matthew Kirtley explores how nuclear might be the missing piece of the jigsaw. Rolls-Royce has recently claimed that […]
