TikTok has expanded its search advertising analytics: Search Ads now includes Impression Share and Top 1 Impression Share metrics, showing what proportion of eligible ad impressions a campaign receives and how often it secures the first ad position. At the same time, the platform has updated its Keyword Suggestion Tool with ready-made sets of search keywords. For advertisers, this is an opportunity to assess competition in TikTok search more accurately and identify room to scale.
Key Takeaways
- On October 30, 2026, TikTok introduced new Search Ads tools in its Q4 advertising product preview.
- Impression Share shows the proportion of eligible search ad impressions received by an advertiser.
- Top 1 Impression Share measures the proportion of eligible impressions in the first advertising position.
- The metrics are available at campaign, advertiser, and keyword level for eligible accounts.
- The Keyword Suggestion Tool now offers ready-made Brand and Category Keyword Packs with daily updates to recommendations.
- Availability of the new features depends on the ad account, campaign type, and market.
What Has Changed in TikTok Search Ads?
In its October Product Preview, TikTok introduced two additions to Search Ads Campaign: new search impression share metrics and automatically generated keyword sets.
Previously, advertisers could analyze spend, clicks, impressions, and conversions, but those figures did not fully answer how many potentially eligible advertising impressions their campaigns were missing.
For example, 10,000 impressions could represent either strong coverage of available search demand or just a small fraction of possible inventory. Without more context, it is difficult to assess scaling potential.
The new metrics help reveal that difference. However, they do not show the entire volume of searches on TikTok: the calculation concerns only impressions for which the ad is eligible.
Impression Share: How Many Search Impressions Does an Ad Receive?
Impression Share (IS) is the percentage of eligible search ad impressions that a campaign receives.
Consider a hypothetical example: if an ad receives 4,000 impressions out of 10,000 eligible search ad impressions, its Impression Share is 40%.
This means the advertiser reached 40% of the relevant ad inventory. However, the remaining 60% cannot necessarily be captured simply by increasing the budget.
Competition, bids, budget, keyword selection, creative relevance, and changes in search demand all affect the result.
TikTok’s documentation says this metric helps assess ad visibility and identify opportunities to adjust budgets, bids, keywords, and ad creatives.
Top 1 Impression Share: How Often Does an Ad Get the First Position?
Top 1 Impression Share shows the percentage of eligible impressions in the first advertising position that an advertiser manages to win.
This is a separate metric from overall Impression Share. A campaign may appear regularly in search results but secure the most visible advertising placement much less often.
A high overall IS therefore does not necessarily mean dominance in the first position. And a low Top 1 Impression Share does not prove that a campaign performs poorly: acquisition costs and conversions also matter in performance advertising.
Another relevant point is TopSearch, TikTok’s advertising solution for the first sponsored position in search results. It uses an auction model with CPM pricing. If a TopSearch ad fails to win the first position, it does not automatically move to a lower advertising position within that format.
According to TikTok’s documentation, the new metrics may be displayed for eligible Search Ads Campaign and TopSearch campaigns. Availability depends on whether the feature is supported in the specific account.
Where to Find the New Metrics in TikTok Ads Manager
TikTok describes three levels of Impression Share analysis: advertiser, campaign, and individual keyword.
- Advertiser level. Helps assess overall presence across eligible search advertising inventory.
- Campaign level. Allows advertisers to compare impression share across different campaign areas.
- Keyword level. Helps identify queries for which ads receive only a small proportion of eligible impressions.
Keyword-level detail offers the greatest practical value for optimization. It allows advertisers to distinguish queries that already capture a substantial share of eligible impressions from those that may have more room for growth.
If Impression Share is missing from reporting, that does not necessarily indicate a technical issue. TikTok explicitly warns that availability depends on the market, advertising product, and rollout stage.
How to Use Impression Share to Scale Campaigns
A low impression share may point to growth potential, but advertisers should identify the cause before changing settings.
The Campaign Spends Its Entire Budget
If an ad regularly uses its entire available budget, TikTok recommends considering an increase. This may help generate additional impressions if the campaign is budget-constrained.
However, raising the budget makes sense only if campaign performance meets business objectives. A low Impression Share alongside a high CPA is not, by itself, a reason to spend more.
The Budget Remains Unspent
If a campaign does not use its allocated budget, TikTok advises checking whether bids are competitive for the selected keywords.
Advertisers should also assess the relevance of creatives and landing pages, keyword coverage, and possible targeting restrictions.
In the described update, TikTok does not provide a separate metric that precisely splits lost impression share into losses caused by budget and those caused by ad rank. The cause therefore needs to be inferred from a combination of metrics.
Impression Share Is Low, but CPA Is Good
This is one of the most interesting scenarios for testing scale. If a keyword already drives profitable conversions but captures only a small share of eligible impressions, an advertiser can explore ways to extend its reach.
It is important to change parameters gradually and monitor whether the cost per conversion remains acceptable. A larger impression share does not guarantee a proportional increase in profit.
Keyword Packs: TikTok Automates Search Keyword Discovery
The second part of the update concerns the Keyword Suggestion Tool. The tool can now recommend ready-made thematic keyword groups called Keyword Packs.
TikTok distinguishes between two types of packs:
- Brand Keyword Packs. Groups of searches related to brands.
- Category Keyword Packs. Groups of searches united by a product category or topic.
Advertisers can review a suggested pack and add it through the usual workflow in the Keyword Suggestion Tool.
Recommendations are refreshed daily. To generate them, TikTok uses search volume, CPC, competition data, and its own machine-learning models.
This reduces the amount of manual work required to build keyword lists. However, automatically generated lists should not be treated as a complete strategy: before adding them, advertisers need to check query relevance, user intent, and alignment with the product being advertised.
Brand-related queries deserve particular scrutiny because a recommendation does not override TikTok’s requirements for advertising content, trademarks, or other platform policies.
How TikTok Search Ads Are Becoming More Like Google Ads
In Google search advertising, impression share metrics have long been used to assess campaign competitiveness and growth potential.
The arrival of similar logic in TikTok means advertisers now have more tools for working with search demand, rather than relying solely on the familiar algorithmic distribution of videos in the feed.
However, TikTok Search Ads is not becoming a complete copy of Google Search. Search behavior, content formats, ad inventory, and user behavior differ between the two platforms.
In addition, TikTok has not yet publicly explained every detail of how eligible but missed search impressions are calculated. Impression Share on TikTok and Google Ads should therefore not be compared mechanically as identical metrics.
How the New Tools Fit Into TikTok Ads Automation
The update continues a series of changes to TikTok search advertising. In early October, the company introduced Smart+ for Search Ads Campaign, expanding the automation of keywords and ad creatives.
UAGEEK covered these changes in an article about TikTok Ads expanding AI automation with Smart+ Search Ads and a new ad network.
The new Keyword Packs help build initial lists of queries faster, while Impression Share adds a way to assess how effectively a campaign uses eligible search inventory.
TikTok is therefore automating some settings while providing more information for monitoring results.
What Media Buyers Should Check After the Update
If the new features are already available in your account, start with an audit of existing search campaigns.
- Reporting. Check whether Impression Share and Top 1 Impression Share are available at keyword level.
- Budget. Determine whether campaigns spend their allocated budgets in full.
- Bids. For campaigns with unspent budgets, check whether bids are competitive.
- Keywords. Review the suggested Brand and Category Keyword Packs before adding them.
- Relevance. Check whether search queries, video creatives, and landing pages are aligned.
- Economics. Evaluate Impression Share changes alongside CPC, CPA, conversions, and ROAS.
A proper analysis also requires understanding the differences between basic traffic cost metrics. UAGEEK explains these in more detail in its article on CPM and CPC in TikTok Ads.
Limitations: What TikTok Has Not Yet Explained
Despite the official announcement, several details remain unclear.
TikTok has not published a complete list of countries and accounts where Keyword Packs are available. It also has not fully explained the methodology for calculating all missed impression opportunities or introduced separate metrics for losses caused by budget or ad rank.
Furthermore, the new metrics do not prove that increasing bids will improve any particular campaign’s performance. They simply provide more information for decision-making.
Conclusion
TikTok Search Ads has received an important update for search advertising. Impression Share and Top 1 Impression Share help assess eligible ad inventory and impression competitiveness, while Keyword Packs speed up keyword list preparation.
For advertisers, the main benefit is not the new numbers themselves but the ability to identify more precisely where a campaign is budget-constrained, where bids need reviewing, and which search queries deserve further testing.
However, campaigns should be scaled based on conversions and profitability, not solely to increase search impression share.
