SEO TikTok
TikTok SEO is the practice of optimizing TikTok videos and profiles so they appear more often in TikTok search results and related discovery surfaces like the For You Page.
What I’d do first
- Start with keyword research using TikTok's own search bar.
- Place keywords in captions, on-screen text, and spoken audio.
- Use 3-5 hashtags: broad, niche, and branded.
- Match content to search intent, not just a broad topic.
- Measure performance in TikTok analytics to refine your approach.
I've made plenty of mistakes here, so I'll share what actually works.
What I'd do first
Start with keyword research. Open TikTok's search bar and type in a topic related to your niche. Look at the autocomplete suggestions — those are real queries people are searching. Also check the search results page for the top videos and note the words they use in captions, on-screen text, and hashtags. Tools like Google Trends or Ahrefs can help expand your list. Pick 3-5 phrases that match your audience's intent.
The path I'd take
- Research keywords: Use TikTok search autocomplete and competitor videos to find phrases your audience uses.
- Optimize your profile: Add relevant keywords to your bio, display name, and username.
- Create content around one keyword per video: Focus each video on answering a specific query.
- Place keywords naturally: Include the main keyword in the caption, on-screen text, and spoken audio. Write captions for humans first.
- Use 3-5 hashtags: Mix broad (e.g., #SEO), niche (e.g., #TikTokSEO), and branded tags. Avoid stuffing.
- Hook viewers in the first 2 seconds: Start with a clear, benefit-driven statement that matches the search intent.
Watch-outs
- Keyword stuffing: Cramming keywords into captions or hashtags makes content look spammy and can hurt performance.
- Generic hashtags only: Using only broad tags like #fyp or #viral makes your content too competitive to stand out.
- Reusing off-platform videos: TikTok favors native content. If you repost from Instagram or YouTube, adapt the hook, pacing, and aspect ratio.
- Ignoring measurement: Don't just post and forget. Check TikTok analytics to see which keywords and formats drive search views.
What I got wrong
I used to stuff 15 hashtags into every caption, thinking more was better. Turns out, TikTok's algorithm prefers relevance over volume. I also ignored on-screen text — now I know that TikTok uses OCR to read text in videos, so adding keywords there helps. Another mistake: I reused YouTube videos without re-editing. TikTok rewards fast pacing and vertical format, so take the time to adapt.
