The "Business vs. Personal" Dilemma

Before you post, you must choose your account type. This is the most common mistake eBay sellers make in 2025.

Option A: Personal Account

  • Access to Trending Music
  • Higher Viral Potential
  • No Link in Bio (until 1k followers)

Best for: New accounts trying to grow fast

Option B: Business Account

  • Instant Link in Bio (0 followers needed)
  • Analytics Tools
  • No Commercial Music (Harder to go viral)

Best for: Sellers who need clicks immediately

💡 Our Recommendation: Start with a Personal Account to build an audience using trending sounds. Once you hit 1,000 followers, you get the link and keep the music. If you absolutely need a link today, switch to Business, but expect lower views.

TikTok SEO: The New "Hashtags"

In 2025, TikTok is a search engine. Users don't just scroll; they search for "vintage nike jacket" or "pokémon cards." To rank, you must optimize three things:

  • Spoken Keywords: The algorithm "listens" to your video. If you are selling a camera, literally say "This is a vintage Canon AE-1" in the first 3 seconds.
  • On-Screen Text: Add text bubbles in the TikTok editor that say the exact item name. The algorithm reads this text to categorize your video.
  • The 3-Line Description: Don't just use hashtags. Write a natural sentence: "Found this rare 1990s Chicago Bulls t-shirt at a thrift store today." Then add 3-4 specific hashtags like #vintageclothing #ebayfinds.

How to Post (Step-by-Step)

  1. 1

    The "Link in Bio" Setup

    Do not change the link in your bio for every item. Instead, use a "Link Tree" or the eBay Store link we provide you.
    Pro Tip: In your bio, write: "👇 Shop these finds here:" pointing down to the link.

  2. 2

    Upload & Add Sound

    Upload your VidFlipper export. Tap Add Sound and look for a song with a "blue checkmark" or a "Trending" arrow next to it. Set the volume to 5% so it plays in the background without overpowering your video.

  3. 3

    The "Pinned Comment" Trick

    Since you cannot put a clickable link in the caption, post a comment on your own video immediately:
    "Link to buy is in my bio! (Item #42)"
    Then Long Press that comment and select "Pin Comment" so it stays at the top.

Common Questions

Should I use TikTok Shop?

If you have high-quantity inventory (10+ of the same item), yes. But for unique 1-of-1 eBay listings, TikTok Shop is difficult to manage. Focus on driving traffic to eBay instead.

My views are stuck at 200. Why?

This is usually a "retention" issue. Ensure your video has a "Hook" in the first 2 seconds (e.g., visual movement, text popping up). If the video is static, users scroll instantly.
