TikTok has added new tools to Search Ads for analyzing search auctions and finding keywords. In an update dated October 30, 2026, the company introduced Impression Share and Top 1 Impression Share to help advertisers assess the share of ad impressions they receive. At the same time, the Keyword Suggestion Tool gained ready-made packs of brand and category queries. For media buyers, this offers a more precise way to identify untapped search traffic, but the metrics alone do not show whether scaling it will be profitable.
Key Takeaways
- On October 30, 2026, TikTok announced Impression Share and Top 1 Impression Share for search advertising.
- Impression Share measures the share of impressions received out of available search opportunities.
- Top 1 Impression Share shows the share of impressions received in the first ad position out of the corresponding eligible opportunities.
- The metrics are intended to be available at the advertiser, campaign, and keyword levels.
- The Keyword Suggestion Tool gained Brand Keyword Packs and Category Keyword Packs, with recommendations refreshed daily.
- Availability depends on the account, market, campaign type, and stage of rollout.
What’s new in TikTok Search Ads?
TikTok introduced these features in its fourth Product Preview of 2026. The update applies to Search Ads Campaign, which displays ads to users in TikTok search results.
Unlike ads in the recommendation feed, the search format lets advertisers address interest that users have already expressed. A person may search for a specific brand, a product review, a comparison of products, or a solution to a particular problem.
Search Ads Campaign supports the Traffic, Sales, Lead Generation, and App Promotion objectives. TikTok previously expanded automation for these campaigns through Smart+.
UAGEEK has already covered the Smart+ Search Ads update and TikTok Ads’ new automation tools. The latest release adds search impression diagnostics and a faster way to build keyword lists.
Impression Share: what share of search impressions does an ad receive?
Impression Share is the percentage of available impressions in TikTok search results that an advertiser’s ads actually received.
For example, if the system estimates 10,000 available impressions and the ads receive 4,000, Impression Share is 40%.
This metric helps answer a question: does a campaign receive most of the available impressions for its keywords, or is there potentially room to grow?
However, TikTok does not disclose the detailed methodology it uses to estimate all eligible auctions in which an advertiser did not receive an impression. Impression Share should therefore be treated as the platform’s diagnostic estimate, not an exact forecast of additional traffic.
Top 1 Impression Share: how often does an ad take the first position?
The second metric, Top 1 Impression Share, estimates the share of impressions received in the first ad position out of the corresponding eligible opportunities.
This is not the same as the proportion of all delivered impressions that appeared in first place. TikTok uses a separate set of eligible first-position opportunities in its calculation.
The metric may be useful for brand queries, new product launches, and campaigns where visibility at the top of search results matters.
But a high share of first-position impressions does not automatically mean a high CTR, low CPA, or better ROAS. Advertisers may pay more for extra visibility than the value it brings to their business.
Where are the new TikTok Ads metrics available?
According to the official announcement, Impression Share and Top 1 Impression Share are intended to be available in TikTok Ads Manager at three levels:
- Advertiser. To assess overall presence in the available search inventory.
- Campaign. To compare individual advertising initiatives.
- Keyword. To identify specific queries with potential for additional impressions.
TikTok’s help documentation says the metrics may appear for eligible Search Ads Campaign and TopSearch campaigns. TopSearch is a separate search advertising product that offers placement in the first sponsored position.
Availability is not the same for all advertisers. It depends on the account, campaign type, country, and current stage of product rollout.
TikTok has not published a complete list of markets supporting the new metrics. Having Search Ads available in a particular location therefore does not guarantee access to Impression Share.
Why a low Impression Share does not always indicate a budget problem
If a campaign receives only a small share of available impressions, there may be several reasons: insufficient budget, uncompetitive bids, a limited keyword list, low creative relevance, or strong competition.
TikTok recommends starting by checking budget utilization.
The campaign spends its entire budget
If a campaign consistently uses all of its available budget while Impression Share remains low, increasing spending may help it receive more impressions.
Before changing the budget, however, review actual CPA, ROAS, conversion volume, and conversion quality. Additional impressions will not necessarily deliver conversions at the same efficiency.
The budget is not fully spent
If a campaign is underspending, TikTok advises checking whether the bids for selected keywords are competitive.
In that situation, simply increasing the budget may change nothing because the campaign is already not using the funds available to it.
It is also worth checking how well video creatives and landing pages match the search queries. Even a competitive bid does not guarantee an effective result if the ad fails to match the user’s intent.
What TikTok does not yet show in Impression Share
In Google Ads, advertisers can analyze Search Lost IS (Budget) and Search Lost IS (Rank) separately to assess impressions lost because of budget and Ad Rank.
TikTok’s official documentation for the new search metrics does not yet describe an equivalent breakdown.
This means Impression Share indicates the scale of missed opportunities but does not automatically explain how much of the loss is caused by budget, bids, or relevance.
TikTok has also not published a detailed formula for estimating eligible impressions. It is therefore incorrect to treat the absolute Impression Share values from TikTok and Google Ads as fully equivalent metrics.
Keyword Packs: ready-made sets of brand and category queries
The second part of the update concerns the Keyword Suggestion Tool, which helps advertisers find search keywords.
TikTok has added the ability to get ready-made keyword groups of two types:
- Brand Keyword Packs. Sets of queries associated with brands.
- Category Keyword Packs. Sets of queries grouped by product category.
Advertisers can preview the suggested groups and add them to a campaign without collecting each keyword manually.
Recommendations are updated daily. TikTok uses machine learning and signals including search volume, CPC, and competition to generate them.
However, refreshing recommendations daily does not mean all historical demand or cost-per-click data is completely recalculated every 24 hours. TikTok describes how often the packs are updated but does not disclose the complete methodology for calculating each metric.
How to use Brand and Category Keyword Packs
For brand campaigns, Keyword Packs can reduce the time spent finding relevant variations of product and brand names. This is especially useful when launching a new product or expanding an assortment.
Category packs can help identify additional queries from users who are looking for a type of product rather than a specific brand.
For example, a sports shoe retailer could separately test brand-related queries and broader category phrases associated with running shoes.
However, advertisers should not automatically add every recommended keyword. Before launch, check relevance, advertising restrictions, potential costs, and whether the landing page is a good match.
Particular care is needed with competitors’ brand names. A query appearing in TikTok’s recommendations does not mean every way of using it in advertising is permitted or free from legal risk.
How to evaluate the performance of new keywords
Impression Share helps assess visibility, but scaling decisions also require other metrics.
- CTR. Shows how often users click an ad after seeing it.
- CPC. Helps assess the actual cost of acquiring a click.
- CVR. Shows the share of users who complete the desired action.
- CPA. Shows the cost of acquiring a conversion.
- ROAS. Relates ad spending to attributed revenue.
If a campaign has low Impression Share but consistently generates profitable conversions, this may justify a controlled test of higher budgets or bids.
If Impression Share is low and CPA already exceeds the acceptable threshold, the first priority should be improving efficiency rather than buying additional inventory.
For a correct interpretation of costs, it is also worth considering the differences between CPM and CPC in TikTok Ads. The cost of an impression or a click does not, by itself, determine a campaign’s return.
A practical checklist for media buyers
- Check availability. Look for Impression Share and Top 1 Impression Share in TikTok Ads Manager reports for eligible Search Ads Campaign.
- Start with keywords. Identify queries with low Impression Share and proven conversion value.
- Assess budget utilization. If the budget is fully spent, consider a controlled test of increased spending.
- Check bids. If the campaign is underspending, determine whether the bids are competitive enough.
- Review Keyword Packs. Select relevant brand and category queries without automatically adding every recommendation.
- Compare the data with conversions. Evaluate CPA, ROAS, and the quality of results after making changes.
Avoid changing budgets, bids, keywords, and creatives all at once without a separate test plan. Otherwise, it will be difficult to understand what actually affected performance.
What this means for TikTok Search Ads in 2026
The update develops TikTok search advertising in two directions: a more transparent assessment of available ad inventory and greater automation of keyword research.
For performance teams, this could reduce the time spent diagnosing campaigns and finding additional demand. At the same time, TikTok does not yet provide a complete breakdown of the reasons for lost impressions and does not guarantee access to the new features in every account.
The guiding principle remains unchanged: scale not Impression Share itself, but search queries that generate valuable conversions at an acceptable cost.
