TikTok Spark Ads vs In-Feed Ads Performance 2026
TikTok’s own A/B testing recorded a 134% higher video completion rate for Spark Ads than for standard In-Feed Ads, plus a 157% higher 6-second view-through rate. Both figures come from TikTok’s 2022 internal Spark Ads test data, published on its business blog. This report compares the two formats on completion, conversion, cost and creative control, using TikTok’s published tests, its own campaign case studies and 2025 platform benchmarks.
TikTok Spark Ads vs In-Feed Ads
How Do TikTok Spark Ads vs In-Feed Ads Compare on Performance?
TikTok publishes four format-level comparisons on its business blog. All four are drawn from internal A/B tests run in 2022, split across the brand auction and the performance auction.
The company has not released an updated Spark Ads test since. Every widely circulated version of these numbers traces back to the same footnotes.
| Metric | Spark Ads vs standard In-Feed Ads | Test auction |
|---|---|---|
| Video completion rate | +134% | Brand |
| 6-second view-through rate | +157% | Brand |
| Conversion rate, profile landing page UI | +69% | Performance |
| Cost per acquisition, profile landing page UI | −37% | Performance |

The completion gap is the number media buyers quote most. It also matches the broader pattern in TikTok video completion rate data, where retention tracks how native a video feels rather than how polished it is.
What Separates Spark Ads From In-Feed Ads in Ads Manager?
The two formats bill differently because they count clicks differently. TikTok’s Business Help Center, updated June 2026, sets out the mechanics.
| Attribute | Spark Ads | Non-Spark In-Feed Ads |
|---|---|---|
| Creative source | An organic TikTok post, with creator authorization where needed | Built in Ads Manager |
| Paid clicks counted | CTA button and ad caption | CTA button, caption, nickname, profile photo, swipe-left |
| Display name and ad text | Taken from the organic post, not editable at ad creation | Set by the advertiser |
| Extra reported metrics | Paid followers, paid profile visits, music clicks, anchor click rate | Not reported |
| Engagement attribution | Returns to the original organic post | No organic post to attribute to |
| Account limit | 10,000 Spark Ads per Ads Manager account | Not stated |
Source: TikTok Business Help Center, About Spark Ads, updated June 2026
Spark Ads count fewer click surfaces as paid clicks. A profile visit or a swipe-left registers as a paid click on a non-Spark ad and as a separate reported action on a Spark Ad, which is worth knowing before comparing CTR across the two.
TikTok Spark Ads vs In-Feed Ads in Published Campaign Results
One case study on TikTok’s Spark Ads page compares both formats inside a single account. Bridal jewellery retailer James Allen ran a prospecting campaign and recorded a 25% higher CTR and a 24% higher CVR on Spark Ads than on its non-Spark Ads.
The remaining case studies report outcomes without a non-Spark control. Isle of Paradise recorded 500% ROI, 45 million video views and a 68% increase in revenue per week. Shufersal reported sales up 251% against the two weeks before its campaign, with online sales moving from 10% to 37% of its total.
Photomyne ran 12 organic posts from 10 mid-tier creators as Spark Ads, reporting a 27.5% conversion rate for app installs and a 50% drop in CPA. Monnalisa reached over 1.5 million users and 8 million impressions.
Schwarzkopf ran its own A/B test across traditional In-Feed Ads and Spark Ads. TikTok states the test found Spark Ads more effective for that campaign but publishes no figures for it.

What Do TikTok Ad Costs Look Like Across 2025?
Format choice sits inside a platform where reach got more expensive through 2025. Triple Whale’s benchmark covers brands using its platform between January 1 and December 31, 2025, and measures all TikTok ad formats together rather than Spark Ads on their own.
| Metric | 2025 | 2024 | YoY change |
|---|---|---|---|
| CPA | $32.74 | $30.14 | +8.64% |
| CPM | $13.26 | $11.43 | +16.00% |
| CVR | 2.01% | 2.15% | −6.20% |
| ROAS | 2.21 | 2.34 | −5.70% |
| AOV | $74.12 | $72.19 | +2.68% |
| CTR | 1.77% | 1.56% | +13.74% |
| MER | 0.39 | 0.37 | +5.98% |

CTR rose 13.74% while CVR fell 6.20%. Clicks got easier to earn and harder to convert, which is the case advertisers make for creative that carries social proof into the click. Rising auction prices are also visible in wider TikTok ad revenue figures.

Median CTR spanned 0.49% in Pets & Animals to 0.73% in Electronics. Those margins put weight on the opening frames, which is where 3-second hook retention benchmarks do most of their work.

Where In-Feed Ads Still Beat TikTok Spark Ads
Spark creative is locked. The display name and ad text come from the organic post and cannot be edited during ad creation, so variant testing means finding or commissioning another post.
In-Feed Ads need no organic post and no creator authorization code. TikTok lets advertisers set authorization duration, but the creator still has to issue it.
Click accounting favours In-Feed for direct response. Nickname, profile photo and swipe-left all count as paid clicks on non-Spark ads, and every one of those routes leads somewhere the advertiser controls.
Spark Ads also depend on content that already earned attention, which is why sponsored versus organic engagement data matters before boosting, and why engagement rates by follower count often favour smaller accounts.
FAQs
How much better do TikTok Spark Ads perform than In-Feed Ads?
TikTok’s 2022 internal A/B test recorded a 134% higher completion rate and a 157% higher 6-second view-through rate for Spark Ads. Its profile landing page UI added a 69% higher conversion rate and 37% lower CPA in the performance auction.
Are TikTok Spark Ads cheaper than In-Feed Ads?
TikTok reports a 37% lower CPA for the Spark Ads profile landing page UI in its 2022 performance auction test. It publishes no Spark versus In-Feed CPM comparison, so cost per impression cannot be answered from its data.
What do advertisers on Reddit say about Spark Ads vs In-Feed Ads?
Reddit threads on TikTok advertising are single-account anecdotes without stated sample sizes, periods or objectives. Useful for hypotheses, not benchmarks. TikTok’s published +134% completion difference and Triple Whale’s 2025 figures are the measured comparisons.
Why do Reddit threads mention Spark Ads authorization problems?
Spark Ads need an authorization code issued by the creator, a step In-Feed Ads skip entirely. TikTok’s Business Help Center documents the process and lets advertisers customise how long each code stays valid.
How many Spark Ads can one TikTok account run?
Each TikTok Ads Manager account supports a maximum of 10,000 Spark Ads. Videos up to 10 minutes can be sparked, and an organic post has to be un-authorized before it can be deleted.
