Online advertising in 2025 is driven by AI, privacy-centric targeting, and immersive formats like AR and interactive video. Brands focus on delivering value-driven, non-intrusive ads tailored to user preferences across devices.

HubSpot has published a new guide, ‘Online advertising: All you need to know’.

Corey Braccialini says, “Whether you‘re on the lookout for the best Indian restaurant in your neighborhood or looking for a specific SaaS tool, you’re likely going to turn to a search engine to find what you need.

The same goes for your audience.

With search engines like Google, Perplexity, and many others being a core part of daily routines, running paid ads can catch your audience’s attention on these platforms.

And let’s not overlook how much time people spend on social media — an average of two hours and 23 minutes each day, according to Statista (though some of us — cough — may be pushing those averages ever higher). In most cases, social media advertising should be part of your overall marketing plan.

There are plenty of ways to advertise your business strategically. First think about who you’re trying to reach.”
