How TikTok’s Search Algorithm Works (2024 Update)

TikTok ranks videos based on:

  1. User Engagement (likes, shares, comments, watch time)
  2. Video Completion Rate (videos watched to the end rank higher)
  3. Relevance (keywords, hashtags, captions)
  4. Account Authority (consistent posting, follower interaction)

Key Difference from Google:

  • Google ranks based on backlinks and domain authority.
  • TikTok ranks based on engagement and retention.

Step 1: Keyword Research for TikTok SEO

Find Viral TikTok Keywords

  • Use TikTok’s Search Bar: Type a keyword and see auto-suggestions.
  • Check Competitor Videos: See which keywords top creators use.
  • Use Third-Party Tools:
  • TikTok Creative Center (trending hashtags & sounds)
  • ViralMango (TikTok keyword tool)

Example:

  • Instead of “fitness tips,” use “best ab workout at home no equipment” (long-tail, high intent).

Where to Place Keywords

Video Caption (First 3 lines matter most)
Hashtags (Mix broad and niche)
Voiceover & Text Overlays (TikTok scans spoken words)
Video File Name (Before uploading, rename to include keywords)


Step 2: Write SEO-Optimized Captions

  • Hook in the First 3 Seconds: “Stop wasting time on useless workouts!”
  • Include Target Keywords: “This 10-minute ab workout requires NO equipment.”
  • Ask a Question: “Which exercise burned the most fat for you? Comment below!”
  • Add a Strong CTA: “Like & follow for daily fitness tips!”

Bad Caption:
❌ “Try this workout!”

Good Caption:
✅ “This 10-minute ab workout (no equipment!) burns belly fat FAST. 🔥 Save & try it now!”


Step 3: Use the Best Hashtags for Reach

  • 3-5 Hashtags MAX (Overloading hurts visibility)
  • Mix of:
  • Broad (#Fitness, #Workout)
  • Niche (#HomeWorkout, #NoEquipmentAbs)
  • Branded (#YourBrandName)

*Pro Tip: Check *TikTok Creative Center for trending hashtags in your niche.


Step 4: Boost Engagement for Higher Rankings

TikTok’s algorithm rewards engagement. Hack it with:

  • Pinned Comments: Ask a question & pin the best reply.
  • Duets & Stitches: Engage with trending videos.
  • Reply to Comments Fast: Boosts video interaction.
  • Use Polls & Q&A: Increases watch time.

Case Study:
A small business used “Reply to all comments within 1 hour” and saw a 300% increase in video reach.


Step 5: Optimize Video Structure for Retention

  • 0:00-0:03: Hook (“You’re doing squats WRONG!”)
  • 0:04-0:15: Quick value (“Here’s the right form…”)
  • 0:16-0:58: Deep dive (“3 squat variations for max results”)
  • 0:59-1:00: CTA (“Follow for more fitness tips!”)

*Ideal Video Length: *30-60 seconds (TikTok prefers short, high-retention clips).


Step 6: Post at the Best Times for Maximum Reach

  • Best Days: Tuesday, Thursday, Friday
  • Best Times: 6-9 AM & 7-11 PM (local time)

*Tool: Use *TikTok Analytics to track your audience’s active hours.


Bonus: Advanced TikTok SEO Hacks

  1. Add Keywords to Your Profile Bio (Helps with search visibility).
  2. Use Trending Sounds (TikTok promotes videos with viral audio).
  3. Post Consistently (3-5x/week to stay in the algorithm).
  4. Optimize Thumbnails (Use bold text & faces for CTR).

Mistakes to Avoid

Ignoring the First 3 Seconds (Low retention = low reach).
Using Irrelevant Hashtags (#FYP doesn’t work anymore).
Posting at Random Times (Misses peak traffic).
