Spark Ads vs Non-Spark Ads: Which to Use in 2025

Spark Ads achieve 134% higher completion rates and 43% higher conversion rates compared to standard in-feed ads.

The difference isn't small. Spark Ads consistently outperform because they're not technically ads—they're organic TikTok posts that you're amplifying with paid distribution.

But Spark Ads aren't always the right choice. Here's when to use each format and how to maximize performance with both.

What Are Spark Ads?

Spark Ads let you promote existing organic TikTok content as paid ads.

Key characteristics:

• Uses an actual TikTok post (from your account or a creator's account)
• Retains all engagement features (likes, comments, shares, profile visits)
• Displays the original creator's username and profile picture
• Shows a small "Sponsored" label but otherwise looks like organic content

How they differ from regular ads:

Regular in-feed ads are uploaded directly to TikTok Ads Manager. They don't exist as organic posts. Users can't engage with them beyond clicking the CTA, and the post doesn't accumulate social proof over time.

Spark Ads are native content that happens to be paid-promoted. All engagement counts toward the original post, building credibility.

Performance: Spark Ads vs Non-Spark Ads

The data consistently shows Spark Ads outperform regular ads across all major metrics.

Performance comparison:

Metric	Spark Ads	Regular Ads	Lift
Completion rate	+134%	Baseline	134% higher
6-second view-through rate	+157%	Baseline	157% higher
Conversion rate	+43%	Baseline	43% higher
Engagement	+142%	Baseline	142% higher
CTR	Up to 64% higher	Baseline	40-64% higher
Install rate	Up to 72% higher	Baseline	40-72% higher

Why Spark Ads perform better:

1. Social proof: Existing likes, comments, and shares signal credibility. Users trust content that others have engaged with.

2. Authenticity: Spark Ads retain the creator's identity and voice. They don't feel like advertising.

3. Engagement compounds: As the Spark Ad runs, new engagement adds to the original post's metrics, creating a flywheel effect.

4. Native user experience: Spark Ads are indistinguishable from organic content except for the "Sponsored" label.

When to Use Spark Ads

Spark Ads work best in specific scenarios:

1. You Have High-Performing Organic Content

If one of your organic TikToks is performing well (high engagement, strong completion rate), amplify it with Spark Ads.

How to identify candidates:

Look for organic posts with:

• 10%+ engagement rate
• High completion rate (50%+)
• Comments indicating interest or questions about the product
• Strong hook that stops scrolling

Why this works:

The content has already proven it resonates. Paid promotion extends its reach beyond your organic followers.

2. You're Running Creator Partnerships

If you work with influencers or UGC creators, Spark Ads let you promote their content while keeping their profile and credibility intact.

Example:

A fitness creator posts about your workout app. Instead of downloading the video and reuploading it as a regular ad (which loses their profile and engagement), you promote it as a Spark Ad. Viewers see the creator's name, existing engagement, and can visit their profile.

Performance benefit:

Creator-led Spark Ads drive higher trust because the creator's identity remains attached. Regular ads uploaded by brands lose that connection.

3. You Want to Build Long-Term Organic Presence

Spark Ads contribute to your organic TikTok profile growth.

How:

• Likes, comments, and shares on Spark Ads count toward the original post
• Profile visits from Spark Ads can convert to organic followers
• Over time, your organic content library builds social proof

Regular ads don't contribute to organic growth. They exist only in the ads ecosystem.

4. You're Testing Organic Content for Future Campaigns

Use Spark Ads to test organic posts before committing to large-scale creator campaigns.

Process:

1. Post organic content or partner with a creator
2. Promote it as a Spark Ad with a small budget ($50-100)
3. If it performs well, scale the Spark Ad or create more content in that style

This de-risks creative production. You're testing with real TikTok users before investing heavily.

When to Use Regular (Non-Spark) Ads

Spark Ads aren't always the best choice. Regular ads offer flexibility Spark Ads don't.

1. You Need Full Control Over Messaging

With Spark Ads, you're promoting existing content. You can't edit the video, change the caption, or A/B test variations easily.

Regular ads give you complete control. You can upload different versions, test multiple hooks, and iterate quickly.

When this matters:

• Direct response campaigns where messaging precision matters
• Apps with complex value propositions requiring specific wording
• A/B testing creative elements (hooks, CTAs, video length)

2. You Don't Have Organic Content

If you're not posting organically on TikTok or don't have creator partnerships, you can't run Spark Ads.

Regular ads work without an organic presence. You upload creatives directly to Ads Manager and launch.

Implication:

If you're purely focused on performance marketing and don't want to invest in organic TikTok content, regular ads are your only option.

3. You Want Advanced Tracking and Customization

Regular ads support more granular tracking and customization:

• Multiple CTA button options
• Custom landing page URLs with tracking parameters
• Detailed A/B testing within Ads Manager

Spark Ads use the original post's settings, which limits flexibility.

4. You're Running Retargeting Campaigns

Retargeting often requires specific messaging ("Come back and finish your download," "Limited-time offer," etc.).

Creating organic posts for every retargeting message isn't practical. Regular ads let you upload purpose-built retargeting creatives.

How to Create Spark Ads

Setting up Spark Ads requires authorization from the TikTok post owner.

If you're promoting your own organic content:

1. Post the video organically on your TikTok account
2. Go to TikTok Ads Manager > Spark Ads
3. Toggle on "Ad Authorization" in your TikTok settings
4. Copy the authorization code
5. In Ads Manager, select "Use Spark Ads" and enter the code
6. Set targeting, budget, and launch

If you're promoting a creator's content:

1. Ask the creator to enable Ad Authorization in their TikTok settings
2. Creator shares the authorization code with you
3. In Ads Manager, input the code to gain permission
4. Promote the post with your budget and targeting

Important: Creators retain full control. They can revoke authorization at any time, which will pause your Spark Ad.

Combining Spark Ads and Regular Ads

The most effective advertisers use both.

Recommended structure:

60-70% of budget: Spark Ads promoting proven organic content or high-performing creator posts.

30-40% of budget: Regular ads for testing new concepts, retargeting, and precise messaging control.

Why this balance works:

Spark Ads deliver higher baseline performance due to social proof and authenticity. Regular ads provide the flexibility to test and iterate rapidly.

Workflow:

1. Test new concepts as regular ads with small budgets
2. Identify top performers
3. Recreate top concepts as organic posts
4. Promote those posts as Spark Ads for scale

This combines the testing speed of regular ads with the performance efficiency of Spark Ads.

Spark Ads Best Practices for App Campaigns

1. Don't over-optimize organic posts for ads

If you create an organic post specifically to turn into a Spark Ad, it often loses authenticity. Let the post exist organically first, then promote it if it performs.

2. Use creator Spark Ads when possible

Spark Ads from creators (not your brand account) drive higher trust and engagement. Partner with 3-5 creators and promote their best posts.

3. Monitor engagement on Spark Ads

Since engagement accumulates on the original post, watch for negative comments or feedback. Respond quickly to maintain credibility.

4. Refresh Spark Ads when engagement slows

If a Spark Ad's engagement rate drops over time, rotate in a new organic post. Don't run the same Spark Ad for months—it will fatigue.

5. Combine with organic posting strategy

Brands that post organically 3-5 times/week have a steady pipeline of Spark Ad candidates. Irregular posting limits Spark Ad opportunities.

Cost Comparison: Spark Ads vs Regular Ads

Spark Ads don't cost more to run, but they typically deliver better ROI.

CPM/CPC: Similar baseline costs to regular ads.

CPI: Often 20-40% lower due to higher conversion rates.

Example:

• Regular ad: $3.50 CPI
• Spark Ad with same targeting: $2.50 CPI

The creative format (Spark vs. regular) drives the efficiency difference, not the media cost.

Spark Ads Limitations

Despite their advantages, Spark Ads have constraints:

1. Dependent on organic content

You can't run Spark Ads without first creating organic posts. This requires maintaining an active TikTok presence.

2. Less control over creative

You can't edit a Spark Ad once it's live. The video, caption, and music are locked to the original post.

3. Creator dependency

If you're promoting a creator's post and they revoke authorization, your Spark Ad pauses immediately.

4. Limited A/B testing

Testing multiple Spark Ads requires creating multiple organic posts, which is slower than uploading variations in Ads Manager.

FAQs

What's the performance difference between Spark Ads and regular ads?

Spark Ads achieve 134% higher completion rates, 157% higher 6-second view-through rates, 43% higher conversion rates, and 142% increased engagement compared to regular in-feed ads. They perform better because they're actual organic content with built-in social proof.

When should I use Spark Ads vs regular ads?

Use Spark Ads when you have high-performing organic content or creator partnerships. Use regular ads when you need full control over messaging, A/B testing capabilities, or don't have organic content to promote.

Can I use someone else's TikTok video as a Spark Ad?

Yes, with permission. The creator must enable the Spark Ads authorization code in their TikTok settings and share it with you. You can then promote their organic post as an ad while retaining all original engagement.

Do Spark Ads cost more than regular ads?

No. Spark Ads have the same media costs as regular ads. However, they often deliver 20-40% lower CPIs due to higher performance, making them more cost-efficient overall.

Can I edit a Spark Ad after launching it?

No. Spark Ads are tied to the original organic post. You can't change the video, caption, or music. If you need to make changes, you must create a new organic post and promote that instead.

Spark Ads are the highest-performing ad format on TikTok for most use cases. If you have organic content or creator partnerships, prioritize Spark Ads. Use regular ads for testing, retargeting, and scenarios requiring full creative control. The best strategies use both.
