TikTok Engagement Tips

Short answer: Absolutely.

TikTok might be a video-first platform, but words play a surprisingly powerful role in getting your content discovered—and engaged with.

From captions to voiceovers, hashtags to comments, TikTok’s algorithm uses language cues to figure out who your video is for. So if you're ignoring keywords, you're missing out.

Let’s break down how the right words can boost your TikTok engagement:

📝 Captions

TikTok uses captions to categorize your video content and recommend it to the right viewers. Tools like TikTok's Keyword Insights show that certain keywords (like “easy,” “quick,” or “beginner”) consistently rank high in performance metrics like impressions and CTR.

Tip: Include 1–2 primary keywords in your caption. For example, instead of “just made this 😍”, try “easy 10-minute pasta recipe 😍”

#️⃣ Hashtags

Hashtags are searchable keywords that help TikTok understand both topic and audience intent.

  • Use broad hashtags like #TikTokMadeMeTryIt or #LifeHacks for reach.
  • Mix in niche-specific hashtags like #budgetmealsforfamilies or #curlyhairroutine to attract targeted viewers.

Pro tip: Don’t overuse them—3 to 5 well-chosen hashtags outperform stuffed lists of irrelevant ones.

🗣️ Text on Screen & Voiceovers

TikTok uses text recognition and voice-to-text transcription to understand your video’s subject.

That means:

  • Text overlays should include key phrases related to your content.
  • Voiceovers that mention relevant terms help TikTok categorize and serve your content to matching search queries.

Example: If your video is about outfit ideas, saying “how to style wide-leg jeans” aloud (or putting it in text) can make it more discoverable to users searching that exact phrase.

🔍 TikTok SEO

TikTok has officially become a search engine—especially among Gen Z. Searches like “what to wear to a wedding,” “easy healthy snacks,” or “how to make iced coffee” are increasingly popular.

Start thinking like a content creator and a search engine optimizer:

  • Use TikTok’s search bar to research phrases your audience is using.
  • Try tools like KeywordTool.io or TikTok’s Creative Center to track trending terms.
  • Position your content around searchable how-tos, tips, and product mentions.

💬 Comments

Yes, even comments matter. TikTok picks up on recurring themes in comment sections.

Encourage keyword-rich comments by adding prompts like:

  • “Which one would you try first?”
  • “Tag someone who needs this recipe!”
  • “What’s your go-to morning skincare product?”

This creates natural keyword variation in your post's engagement—giving TikTok even more signals to boost your content. Make sure to also reply to your comments with actual words, not only emojis!

What you say, write, and display on TikTok isn’t just filler, it’s fuel for visibility.

Strategic keyword placement in captions, hashtags, onscreen text, voiceovers, and comments helps TikTok match your content to the right people at the right time.

So yes, what you write absolutely affects your engagement.

Next time you hit “post,” ask yourself: What would someone search to find this video? Then put that in your caption, overlay, or voiceover.
