KeywordSearch

A one-sentence summary

KeywordSearch is an AI-based audience research platform designed for use with Google and YouTube ads; it enables the creation of actionable audience insights based on business needs, ideal customers, or advertising objectives, and it allows these selected audiences to be integrated into Google Ads.

What is KeywordSearch?

KeywordSearch is operated by KeywordSearch LLC and serves advertisers, content creators, businesses, and marketing agencies. It brings together functions such as AI-driven audience generation, YouTube keyword research, topic expansion, ad material monitoring, and customer reports in a single web-based workspace.

The product’s name might lead one to think that it is merely a traditional keyword search tool, but its actual purpose is more focused on identifying advertising audiences and conducting research for YouTube marketing. Its value lies in organizing various keywords, interests, websites, apps, and channels into audience groups that can be used for further testing.

Overview of Core Competencies

AI Audience Builder

AI Audience Builder accepts information such as a business description, target customers, a list of keywords, or competitors, and generates candidates related to the advertising strategy. A single analysis can take into account various aspects such as interests, search terms, relevant websites, apps, and YouTube channels.

• Generate the target audience based on a business description.
• Identify relevant interests based on the profile of the target customers.
• Expand Google search terms and YouTube keywords.
• Discover related websites, apps, and channels.
• Automatically organize potential audiences by theme.
• Continue to expand the selected keyword group.
• After being saved in a collection, it can be used for different advertising campaigns.

The audience generated by AI represents assumptions regarding targeting, not a guarantee of conversion rates. Advertising teams still need to consider factors such as region, language, purchasing intent, audience size, and brand safety, and they should test actual performance through experiments with small budgets.

AI audience creation process

1. Create an account and select a plan that matches the expected volume of research.
2. Enter a brief description of the business, the products, the target customers, and the advertising objectives.
3. Select templates such as business description, customer profile, keywords, or competitors.
4. Generate candidates for keywords, interests, websites, apps, and channels.
5. Remove items that are irrelevant, ambiguous, sensitive, or pose a high risk to the brand.
6. Organize the candidates into audience groups based on themes and purchasing intent.
7. Save to Collection and record the research hypotheses.
8. Synchronize the selected audience after connecting to Google Ads.
9. Test click-through rates, conversion rates, and customer acquisition costs using small-scale ads.
10. Retain, split, or deactivate audiences based on real data.

One-click synchronization for Google Ads

Plans Pro and above allow connection to a Google Ads account, enabling the creation of the audience segments selected on the platform within that ad account. This process helps to reduce the time required for manually copying keywords as well as configuring website and app targets.

The synchronization feature carries out the actions specified by the user on external advertising accounts; therefore, it is necessary to verify the account details, the customer center, and the write permissions before granting authorization. Organizations should especially avoid accidentally synchronizing the audience of one client to another client’s account.

YouTube keyword research

Keyword research tools identify search terms related to YouTube content and advertisements, and they assist users in making selections by taking into account factors such as search volume, competition level, and relevance. These relevant keywords can be used in video titles, descriptions, tags, and topic choices, as well as in customizing ad audiences.

• Search for YouTube keywords related to the topic.
• Compare search volume, competitiveness, and relevance.
• Generate new words related to the semantics of the current topic.
• Continue to carry out progressive research along with the associated keywords.
• Copy the selected keywords to the deployment workflow.
• Save the research results by project.

Search volume and competition metrics are indicators to be considered; they do not guarantee that a video will rank well or receive views. The choice of keywords ultimately also depends on the quality of the content, the profile of the channel, search intent, region, and date of publication.

Topic Auto Expansion

Topic Auto Expansion is used to continue searching for relevant topics based on an existing set of keywords, while maintaining the semantic relationship with the original topic. It is suitable for expanding the list of target audiences, identifying long-tail topics, and creating more detailed ad groups.

The so-called continuous expansion does not mean that every suggestion is worth implementing. The broader the topic, the more likely it is that relevance will decline and budget will be wasted; therefore, manual screening should be carried out after each round of expansion.

YouTube Ad Spy

YouTube Ad Spy provides a database of ads; users can search for competitive ads by industry or keyword, and view ad metadata, target keywords that may be used, viewing statistics, and metrics such as Spend Trend. The results can be sorted by the number of views or spending trends.

• Public and unlisted YouTube ads were found.
• Examine the creative approaches adopted by competing brands.
• Study ad titles, videos, and metadata.
• Find the keywords that advertising might be targeted toward.
• Sort by view count or spending trend.
• Include valuable keywords in your research.

Ads in databases do not necessarily indicate that a particular creative approach is effective, and views alone cannot prove profitability. Using materials from competitors can serve only for insight and comparison; it is not permissible to copy expressions and materials protected by copyright, trademarks, or advertising regulations.

Collections and project organization

Collections allows keywords, video locations, video ads, and other research items to be grouped together in separate collections, making it easier to switch between different campaigns or clients. It is useful for storing candidate options, reducing duplicate searches, and creating materials for team reviews.

Agency reports and white labeling

The Agency plan includes three users; it allows for the export of AI-driven advertising targeting research in PDF format, and enables the creation of branded reports using the agency’s logo and links. Marketing agencies can use it to present reports to existing clients, or to prepare analyses of potential customer opportunities for prospective clients.

• Conduct separate audience research for different customers.
• Generate a PDF report that can be shared.
• Replace the platform’s brand with the organization’s logo and link.
• Explain to customers the keywords, channels, and website audience.
• Retain customer approval before deployment.
• Combine the conclusions of the report with actual advertising data.

White-labeling only changes the way the reports are presented; it does not mean that the organization owns the source code or algorithms of the platform. External reports should indicate the data timing, assumptions, and limitations, and AI recommendations cannot be presented as audit conclusions that guarantee conversion rates.

Prices and packages

The price information was verified on August 23, 2026; the actual amounts, taxes, exchange rates, and discounts may vary, and the final figures will be those displayed on the settlement page.

KeywordSearch offers three monthly subscription plans: Starter, Pro, and Agency. The annual payment option indicates a 25% discount, but the total cost for each annual plan is not listed in the pricing section. All plans come with a trial period; the exact number of days available for testing, whether a payment is required, and the timing for automatic renewal can be found on the registration and payment page.

The unlimited keyword research option in Starter is not the same as unlimited AI audience research; different quota rules apply to each. Once the quota for AI Audience Searches is exhausted, it is possible to upgrade to obtain more credits, and before making such a purchase it is necessary to estimate the number of customers per month and the frequency of research.

Refund rules

Users who submit a valid refund request within 14 days from the date of purchase will receive a full refund; after 14 days, they generally no longer qualify for a refund. The request must include the name and customer number, and it should be submitted under the topic specified in the refund rules.

Suggestions for package selection

There is a significant difference in price and the amount of AI research between the Starter and Pro versions; it is advisable to test the relevance of the AI model for real business applications before making a purchase. Organizations should also find out the actual pricing for more than three seats, additional customers, and extra amounts of research.

API, GitHub, and open-source status

It has not been confirmed that KeywordSearch provides public APIs, SDKs, Webhooks, or official developer documentation to ordinary customers.

Privacy and Google Account permissions

The platform handles data such as accounts, subscriptions, transaction records, files, user profiles, analytics metrics, devices, and access logs. Once users authorize their Google accounts, it is also possible to access their name, email address, profile picture, as well as other Google data related to the service.

When connecting to Google Ads, the platform states that it will carry out actions such as creating custom audiences based on the user’s instructions, and may store relevant data on servers. The privacy policy does not specify a fixed deadline for deleting various types of advertising data; instead, such data is retained depending on the account’s duration of existence, the needs of the service, and compliance requirements.

• Connect only to the ad accounts that need to be managed.
• Verify that the correct customer center and sub-account are connected.
• Avoid including client confidential information or personal sensitive data in the business description.
• Regularly check and revoke any unused Google authorizations.
• Remove seats promptly when team members leave or a project comes to an end.
• Process audience research and targeting data in accordance with the client’s contract.
• Keep a record when submitting requests to the platform for deletion or correction.

Advertising compliance and usage boundaries

Audience research takes into account the rules of advertising platforms, as well as issues related to privacy, anti-discrimination measures, and restrictions on sensitive topics. Users cannot rely on AI suggestions to create targeted campaigns that deal with health, politics, financial difficulties, minors, or other sensitive categories.

7. Compare different audience groups using a unified concept and a low budget.
8. Decisions are made based on conversion rate, customer acquisition cost, and incremental impact.
9. Regularly deactivate ineffective audiences and update outdated keywords.
10. Reports on the timing of data retention for customers, along with explanatory notes based on manual judgment.
