AdSense limited ads provide a restricted advertising option when personal data cannot be used for ad personalization. They can help publishers monetize eligible page views that cannot receive personalized or non-personalized advertising under the available privacy signals.
Limited ads are not the same as personalized ads, non-personalized ads or an account-level ad-serving limit. Each term represents a different advertising or enforcement condition.
Google explains that limited ads disable the collection, sharing and use of personal data for advertising personalization. However, normal ad-delivery technology may still be installed or cached, advertisements are transmitted to the device, and IP addresses are used to deliver them. 1
This guide explains how AdSense limited ads work, how to manage the setting and how to measure their effect on revenue.
What Are Google AdSense Limited Ads?
Limited ads, also called LTD, are advertisements served without using personal data to personalize ad selection.
Google may attempt to serve an eligible limited ad when a visitor’s preferences do not permit personalized or non-personalized ads, but the required transparency has been established for:
- Special Purpose 1: Security, fraud prevention and error correction
- Special Purpose 2: Delivery and presentation of advertising and content
- Google as an advertising vendor
Under Google’s current implementation, legitimate interest for Purpose 7—ad-performance measurement—is optional. However, some Google Demand click-tracking and measurement capabilities may be unavailable without it. 1
Limited ads do not guarantee that an advertisement will appear. A request must still be eligible, and suitable advertising demand must be available.
Personalized vs Non-Personalized vs Limited Ads
| Feature | Personalized ads | Non-personalized ads | Limited ads |
|---|---|---|---|
| Historical user data for targeting | Permitted when consented | Not used | Not used |
| Interest and demographic targeting | Available | Unavailable | Unavailable |
| Contextual targeting | Available | Available | Available when eligible |
| Personal data used for personalization | Yes, when permitted | No | No |
| Cookie or local-storage consent | May be required | May still be required | More restricted serving scenario |
| Google programmatic demand | Supported | Supported | Supported when the setting is enabled |
| Third-party buyer demand | Supported | Supported | Supported for eligible inventory |
| Invalid-traffic protection | Supported | Supported | Supported |
Google reports personalized, non-personalized and limited ads as different serving conditions. Limited ads are specifically associated with the absence of consent for cookies, mobile identifiers or other local storage used by less restricted advertising modes. 2
AdSense Limited Ads vs Limited Ad Serving
These two terms sound similar, but their meanings are completely different.
AdSense Limited Ads
Limited ads are a privacy-related ad-serving mode. They restrict how personal data can be used for advertising personalization.
Limited Ad Serving
Limited ad serving is an account-level enforcement. Google reduces the number of advertisements the account can show while evaluating traffic quality or because it has detected possible invalid-traffic concerns.
| Term | What is limited? | Main reason |
|---|---|---|
| Limited ads | Data used for ad serving | Privacy and consent signals |
| Limited ad serving | Number of advertisements shown | Traffic-quality assessment or invalid traffic |
| Restricted ad serving | Advertiser eligibility | Policy, restriction or advertiser preference |
| Disabled ad serving | All Google ads on affected inventory | Policy enforcement |
Google confirms that limited ad serving limits the number of advertisements shown, while limited ads restrict what data can be used to serve advertising. 3
Turning the Limited ads setting on or off will not remove an account-level ad-serving limit.
How AdSense Limited Ads Work
A simplified European consent journey can operate as follows:
- A visitor opens your website.
- A certified CMP presents the applicable privacy choices.
- The visitor grants, rejects or customizes consent.
- The CMP creates and communicates a valid TC string.
- AdSense evaluates the consent and transparency signals.
- Personalized ads are considered when the required consent exists.
- Non-personalized ads are considered when their requirements are met.
- Limited ads may be considered when neither of the first two modes is permitted but the required transparency exists.
- An advertisement is served only when the request and available demand are eligible.
Publishers using Google’s Privacy & messaging system can create European regulations messages that support TCF v2.3. Publishers using another Google-certified TCF v2.3 CMP normally do not need a separate limited-ads integration because the TC string contains the signals Google uses to select the appropriate serving mode. 1
What Information Can Limited Ads Use?
Limited ads do not use personal data to personalize which advertisement is shown. However, this does not mean that no information or advertising technology is involved.
Google states that:
- Advertising JavaScript can still be installed or cached.
- Advertising creatives are transmitted to the visitor’s device.
- Creatives may sometimes be cached on the device.
- IP addresses are used to facilitate advertisement delivery.
- Programmatic limited ads can use invalid-traffic-detection-only cookies and local storage.
- The Shared Storage API can be used for invalid-traffic-only purposes when programmatic limited ads are enabled. 1
Therefore, avoid describing limited ads as “completely tracking-free,” “technology-free” or “zero-data advertising.”
A more accurate description is:
Limited ads do not use personal data for advertising personalization, but some technology and data remain necessary to deliver ads and protect the advertising system from fraud.
What Are Programmatic Limited Ads?
Programmatic limited ads allow eligible limited-ad inventory to receive contextual demand through Google Demand and Authorized Buyers.
Contextual demand considers the advertising opportunity and page context without using personal data to create a personalized advertisement for the individual visitor.
When programmatic limited ads are enabled, Google can use invalid-traffic-detection-only cookies and local storage on both consented and unconsented traffic. Google states that it does not require publishers to obtain consent for this specific use case, but it also emphasizes that publishers remain legally responsible for their consent tools and regulatory obligations. 1
This distinction is important:
- Google’s product requirement is not automatically a complete statement of applicable law.
- Publishers should review regulator guidance and obtain suitable professional advice before selecting their configuration.
Are AdSense Limited Ads Enabled by Default?
Yes. Google’s current AdSense documentation states that the Limited ads option is turned on by default and can be disabled through the ad-serving settings. 1
The setting applies to AdSense for Content advertisements and controls whether programmatic demand can participate in eligible limited-ad requests.
How to Enable AdSense Limited Ads
If you previously disabled the setting, follow these steps:
- Sign in to Google AdSense.
- Open Brand safety.
- Select Content.
- Open Blocking controls.
- Click Manage Ad serving.
- Find the Limited ads setting.
- Turn the setting on.
- Save the configuration if requested.
Enabling this setting allows eligible limited-ad requests to receive demand from Google Demand and Authorized Buyers. 4
You do not normally need to add a separate limited-ads script when you are using Google’s Privacy & messaging CMP or another properly configured, Google-certified TCF v2.3 CMP.
How to Disable AdSense Limited Ads
To disable programmatic limited ads:
- Sign in to AdSense.
- Open Brand safety.
- Select Content.
- Click Blocking controls.
- Open Manage Ad serving.
- Find Limited ads.
- Turn the setting off.
Publishers who do not want invalid-traffic-detection-only cookies and local storage used without consent can opt out by disabling this setting. 1
Disabling it can reduce the programmatic demand available for limited-ad requests. This may result in fewer monetized impressions from visitors whose privacy choices do not support personalized or non-personalized ads.
Do not select the setting based only on revenue. Review the data use, privacy requirements and user expectations with your legal or privacy team.
Do You Still Need a CMP?
Limited ads do not remove your responsibility to implement an appropriate consent and transparency process.
Google requires publishers serving personalized ads to users in the EEA, UK and Switzerland to use a Google-certified CMP integrated with the IAB Transparency and Consent Framework. Only traffic from a certified CMP is eligible for personalized ads; traffic from a non-certified CMP may still be eligible for non-personalized or limited ads where supported. 5
However, the availability of limited ads without a certified CMP is not an exemption from Google’s EU User Consent Policy.
Google specifically reminds publishers without a CMP that they must still:
- Identify parties that may collect, receive or use personal data.
- Provide prominent and accessible information about data use.
- Satisfy the other relevant provisions of the EU User Consent Policy. 1
For most AdSense websites receiving European traffic, using Google’s CMP or another certified TCF CMP is safer and easier to manage than attempting to build a custom implementation.
TCF v2.3 and Limited Ads
TCF v2.3 became mandatory for new TC strings generated on or after March 1, 2026. Google’s Privacy & messaging European regulations messages support this version. 6
TCF configuration errors can cause requests to default to limited ads.
Examples include:
- The CMP remaining in a loading or error state
- An empty TC string
- Invalid CMP identification
- A globally scoped TC string
- An outdated TCF version
- Missing TCF signals
- Google missing from the disclosed-vendors section
Google attempts to serve limited ads for several TCF implementation and TC-string errors. Therefore, an unexpectedly high limited-ad rate can indicate either genuine visitor choices or a broken CMP implementation. 6
Do not assume that every limited-ad impression was caused by a visitor intentionally rejecting consent.
How to Track Limited Ads in AdSense Reports
AdSense provides a Serving restriction breakdown that lets publishers compare privacy-related serving modes and evaluate their revenue impact.
Follow these steps:
- Sign in to AdSense.
- Open Reports.
- Create a custom report.
- Click Add breakdown.
- Select Serving restriction.
- Choose a suitable date range.
- Add country and device filters when useful.
- Compare impressions, estimated earnings and RPM.
The report can include:
- Limited ads
- Restricted data processing
- Non-personalized ads
- Basic ads
- Personalization disabled
- No restriction
Serving-restriction data is unavailable for dates before October 11, 2024. Policy-related ad restrictions are not included in this report and must be reviewed separately in the Policy Center. 2
Metrics to Monitor
Compare the following metrics:
- Page views
- Ad requests
- Ad impressions
- Coverage
- Estimated earnings
- Page RPM
- Ad RPM
- Visitor country
- Device category
- Serving restriction
- Date
Create separate reports for:
- EEA traffic
- UK traffic
- Swiss traffic
- Mobile visitors
- Desktop visitors
- New visitors
- Returning visitors
A high number of limited-ad impressions may be normal when many visitors reject or restrict local-storage consent. However, a sudden increase after changing your CMP, theme or caching configuration should be investigated.
Do Limited Ads Earn Less?
Limited ads may have a different level of advertiser demand because they cannot use personal data for ad personalization. However, Google supports contextual programmatic demand from Google and eligible third-party buyers on limited-ad inventory when the setting is enabled. 1
There is no universal percentage by which limited ads earn less than personalized or non-personalized ads.
Revenue depends on:
- Visitor country
- Content niche
- Advertiser competition
- Device type
- Ad format
- Viewability
- Page context
- Season
- Available contextual demand
- Quality of the advertising inventory
Use your Serving restriction report instead of relying on estimates from unrelated websites.
Why Are Limited Ads Not Showing?
Possible reasons include:
1. The Limited Ads Setting Is Off
Check:
Brand safety → Content → Blocking controls → Manage Ad servingConfirm that Limited ads are enabled.
2. No Eligible Demand Is Available
Enabling limited ads does not guarantee an advertisement for every request. A suitable contextual advertisement and eligible buyer must still be available.
3. The CMP Signals Are Incomplete
The request may contain:
- An invalid TC string
- Missing transparency signals
- An unsupported CMP
- A missing vendor configuration
- An outdated TCF implementation
Download and review your AdSense TCF error report.
4. Google Is Not Properly Disclosed
TCF v2.3 requires the Disclosed Vendors section. Google Advertising Products, vendor ID 755, should be included in the CMP configuration for eligible Google advertising operations. 6
5. The AdSense Code Is Missing
Make sure the correct AdSense code is installed on every eligible page and uses the publisher ID from the correct account.
6. A Policy Issue Exists
A Policy Center enforcement can restrict or disable ad serving independently of privacy-related limited ads.
7. An Ad Blocker Is Active
Test using a private browser profile without advertising-blocking extensions.
8. The Ad Unit Is Unfilled
A valid ad request can remain unfilled when no eligible advertisement is available.
Why Is My Limited-Ads Traffic Increasing?
A rising limited-ads percentage can result from:
- More visitors rejecting local-storage consent
- A change in traffic location
- A new European marketing campaign
- CMP configuration errors
- An invalid or outdated TC string
- Google missing from vendor disclosures
- Consent not being preserved across pages
- A cookie or script optimizer delaying the CMP
- A non-certified CMP
- Incorrect regional consent defaults
Use country-level comparisons to determine whether the increase is linked to visitor location. Then check the date when your CMP, WordPress plugins or consent message were last updated.
WordPress Limited Ads Checklist
For a WordPress website, confirm that:
- Only one primary CMP is active.
- The CMP is Google-certified where required.
- The CMP supports TCF v2.3.
- The consent message appears on every relevant page.
- Google is included in the vendor configuration.
- The AdSense code uses the correct publisher ID.
- Cache plugins do not remove the CMP script.
- JavaScript-delay settings do not load ads before the CMP.
- The visitor’s selection is preserved across pages.
- Mobile and desktop consent messages both work.
- The privacy-policy link is accurate.
- Consent-revocation controls work.
- TCF errors are monitored.
- Limited ads are enabled or disabled intentionally.
- Serving-restriction reports are reviewed regularly.
Avoid using separate cookie-banner, CMP, Consent Mode and custom-script plugins without checking whether they duplicate or overwrite one another.
Recommended Limited Ads Review Process
Step 1: Confirm the Setting
Check whether Limited ads are enabled inside Manage Ad serving.
Step 2: Review Your CMP
Confirm certification, TCF version and vendor configuration.
Step 3: Test Consent Choices
Test:
- Consent to all
- Reject all
- Manage options
- Partial consent
- Consent withdrawal
Step 4: Review TCF Errors
Investigate high-volume errors rather than focusing only on one or two isolated requests.
Step 5: Create a Serving Restriction Report
Compare limited ads with non-personalized ads and unrestricted personalized traffic.
Step 6: Segment by Country
Prioritize EEA, UK and Swiss traffic.
Step 7: Compare Revenue and Coverage
Record Page RPM, Ad RPM, impressions and coverage before changing the setting.
Step 8: Make One Change at a Time
Do not simultaneously replace your CMP, modify the theme, change AdSense settings and enable new Auto Ads formats.

Frequently Asked Questions
What are AdSense limited ads?
Limited ads allow eligible advertisements to be served without collecting, sharing or using personal data for advertising personalization. Some technology and data remain necessary for ad delivery and fraud protection. 1
Are limited ads the same as non-personalized ads?
No. Non-personalized ads can use contextual information and certain storage when the applicable requirements are met. Limited ads represent a more restricted serving scenario when personalized and non-personalized advertising are not permitted.
Are limited ads the same as an AdSense ad-serving limit?
No. Limited ads restrict data use. An ad-serving limit reduces the number of advertisements the account can show because of traffic assessment or invalid-traffic concerns. 7
Are limited ads enabled automatically?
Google’s current documentation says the Limited ads setting is enabled by default. Publishers can turn it off through the Ad serving controls. 1
Do limited ads use cookies?
When programmatic limited ads are enabled, Google can use invalid-traffic-detection-only cookies and local storage. These are used for fraud and abuse protection rather than advertising personalization. 1
Do limited ads use IP addresses?
Yes. Google says IP addresses are still used to facilitate transmission of advertisements to visitors’ devices. 1
Can limited ads receive programmatic demand?
Yes. Eligible limited-ad inventory can receive contextual demand from Google Demand and Authorized Buyers when the feature is enabled. 1
Do limited ads guarantee revenue?
No. Advertising demand, request eligibility, visitor location, page context and other factors determine whether an advertisement is returned.
Can I disable limited ads?
Yes. Open Brand safety, Content, Blocking controls and Manage Ad serving. Turn off Limited ads if you do not want the programmatic limited-ads data usage described by Google. 4
Do I still need a certified CMP?
A certified CMP is required when serving personalized ads to users in the EEA, UK and Switzerland. Limited-ad availability does not remove your transparency, consent or policy responsibilities. 5
How can I see limited-ads earnings?
Create an AdSense report and add the Serving restriction breakdown. Select Limited ads and compare estimated earnings, impressions, coverage and RPM. 2
Can TCF errors cause limited ads?
Yes. Google attempts to serve limited ads for several TCF misconfigurations, invalid TC strings and missing consent signals. 6
Conclusion
AdSense limited ads provide a privacy-restricted monetization option when personal data cannot be used for advertising personalization.
The feature can unlock contextual demand from Google and Authorized Buyers, but programmatic limited ads use invalid-traffic-detection-only cookies and local storage. Publishers should review this data use and their applicable legal obligations before deciding whether to leave the feature enabled.
Do not confuse limited ads with limited ad serving. The first is a privacy-related serving mode, while the second is an account-level restriction associated with traffic-quality assessment or invalid traffic.
Use a properly configured TCF v2.3 CMP, monitor TCF errors and create a Serving restriction report to understand how limited ads affect your website. Base your final setting on verified data, user privacy and professional compliance advice—not only on short-term advertising revenue.
