We all know social media is noisy. Like really noisy. Millions of posts go up every single day, and your carefully crafted content can easily get buried. So how do you make sure your post actually gets seen by the right people?

Enter: Hashtag research and optimization — the not-so-secret weapon smart marketers and creators use to supercharge their reach, visibility, and engagement.

Why Hashtags Still Matter in 2025

Despite changes in algorithms and the rise of AI-driven feeds, hashtags are still highly relevant. Here’s what they help with:

  • Discovery: Hashtags are search terms. People do still browse or follow hashtags.
  • Categorization: Platforms use them to understand the context of your content.
  • Engagement: The right hashtags put your post in front of people who care (and will engage).

Instagram, LinkedIn, TikTok, and even YouTube Shorts all benefit from hashtag use — though how you use them will vary a bit per platform (more on that below).

  • Define Your Goals First - This helps you choose between broad, niche, and branded hashtags.
  • Core Keyword Research - Hashtag research = keyword research, just social-specific.
  • Mix Up Hashtag Strategy - This lets your post live in both crowded and quiet spaces — increasing the odds of being seen somewhere.
  • Customize Per Platform
  • Track, Test, and Tweak - Kill off underperforming tags and double down on the ones that bring in real results.

Pro Tips and Mistakes to Avoid

Do: Create a bank of reusable hashtags by theme. Keep an eye on trending tags without chasing them blindly. Rotate your sets to avoid spammy patterns

Don’t: Use banned or broken hashtags (they kill your post visibility). Copy-paste the same set on every post. Use irrelevant hashtags “just for reach” (it backfires).
