What is Hashtag strategy?

Also known as: Hashtag research, Hashtag mix

Definition

A deliberate plan for which hashtags go under which posts — using a mix of popular, niche-specific and branded tags to reach the right audience rather than a random pile of tags.

In-depth explanation

A strong hashtag strategy combines: (1) high-volume tags (#fitness, #foodie — lots of reach, lots of competition), (2) niche tags (#veganbakeryUtrecht — less reach, high relevance), (3) branded hashtags (#GoldCrustBakery — community-building), (4) campaign hashtags (temporary, for specific promotions).

Instagram recommends 3-5 relevant hashtags in 2025 (down from 30). LinkedIn works best with 3-5 broad hashtags. TikTok relies on trending hashtags that change quickly. Agencies need to track this per platform, per client.

Example from agency practice

For client "Plant Vegan Bakery", the agency uses per Instagram post: 2 high-volume (#veganbakery #plantbasedfood), 2 niche (#veganUtrecht #glutenfreeUtrecht), 1 branded (#PlantBites). Average engagement rises 40% compared with random hashtags.
