How to Vet TikTok Creators Before Paying (Using Competitor Ad Performance)

Why Follower Counts and Engagement Rates Lie

Most brands vet TikTok creators the same way. They check follower counts, scroll through recent videos, and calculate an engagement rate. This process feels thorough, but it's built on vanity metrics that don't guarantee sales.

Fake followers are easy to buy. Engagement can be inflated. Even a creator with a genuine, active audience might not be the right fit for your product. Their followers might not be buyers.

The real signal is commercial performance. Has this creator's content already driven sales for a brand like yours? You don't need to guess. The data exists in TikTok's ad library.

Brandsearch Discovery surfaces this data. It shows you every TikTok Spark ad a competitor is running, who the creator is, and how long that ad has been live. An ad running for 25+ days is a winner. The brand is making money. The creator's content is proven to convert.

This is your shortcut. Instead of betting on a creator's potential, you partner with creators who have a track record of driving ROI for your competitors.

Step 1: Find Competitors Actively Using TikTok Spark Ads

Start with a list of 3-5 direct competitors or brands in your niche. These are brands selling similar products to a similar audience.

Open Brandsearch Discovery. Switch the platform filter to TikTok.

Use the 'Search in Brands' function. Type in a competitor's name. This will show you every TikTok ad they are currently running.

Now, apply the 'Spark/Reel' filter. This isolates only creator-led Spark Ads. These are the ads where a brand has paid a creator to promote their product using the creator's own account and content.

Repeat this for each competitor on your list. Your goal is to build a list of brands that are actively investing in TikTok creator partnerships. A brand running 5-10 Spark ads is testing the channel. A brand running 20+ is likely seeing positive ROAS.

Step 2: Analyze the Creators in Your Competitors' Winning Ads

Scroll through the list of Spark ads for each competitor. Click on individual ads to open the detailed view.

Note the creator's handle displayed on the ad. This is your potential partnership candidate.

The key metric to evaluate is Running Days. This tells you how long the ad has been active. An ad that has been running for 3 days is a test. An ad that has been running for 25, 60, or 90+ days is a winner. The brand is pouring budget into it because it's profitable.

Also, check the Call-to-Action (CTA) and funnel type. Ads with a "Shop Now" CTA driving to a product page are high-intent. They are designed for direct response and sales.

Compile a list of creators who appear in multiple long-running ads, especially across different competitors. A creator featured in winning ads for three different supplement brands is a proven asset in that niche. Their content style, audience, and presentation consistently convert.

Step 3: Validate and Pitch with Unbeatable Data

You now have a list of pre-vetted creators. The validation isn't based on your opinion—it's based on your competitors' ad spend. They have already paid to prove these creators can drive sales.

Use this data to craft a compelling pitch. Instead of a generic outreach email, reference their successful work.

"Hi [Creator], I saw your fantastic Spark ad for [Competitor Brand] that's been running for over 60 days. The angle on [specific hook] really resonated. We have a similar product and believe your audience would love it. We'd like to discuss a partnership."

This approach shows you've done your homework. You're not just another brand spraying emails. You're a savvy operator who recognizes their proven value.

Negotiate rates based on this demonstrated performance, not just follower count. A creator who consistently appears in winning ads for 8-figure brands can justify a higher rate—and is likely to deliver a better return.

Use Brandsearch Discovery as an ongoing system. Set aside 20 minutes each week to check on your competitor shortlist. You'll discover new, validated creators before they become oversaturated and expensive, turning competitor intelligence into a scalable creator sourcing channel.

The Bottom Line

Follower counts are a weak proxy for commercial success. Competitor ad performance is a direct signal.

The method is simple: find competitors scaling on TikTok, identify the creators in their long-running Spark ads, and pitch based on proven results. You de-risk your creator budget and invest in partnerships with a known history of driving sales.

This workflow replaces guesswork with data. You stop paying for potential and start paying for performance.
