Google shows you personalized ads across its services by tracking your interests and browsing habits
You cannot stop Google from showing you ads entirely — that is how Google funds its free services. But you can turn off the tracking that makes those ads personalized to you. When you disable personalized ads, Google will still show you advertisements, but they will be based on what you are doing right now (like the search terms you just typed) rather than a profile of your interests built over months.
The controls live in your Google Account settings, not in individual apps or browsers. One change affects ads across Gmail, YouTube, Google Search, and most other Google services you use while signed in. The process takes about five minutes.
Key Takeaways
- Disabling personalized ads in your Google Account settings stops Google from using your browsing history and interests to target ads, but you will still see ads based on your current activity.
- The main control is the "Ads Personalization" toggle in your Google Account, which you reach through myaccount.google.com.
- Turning off personalized ads in your Google Account does not affect ads shown by other companies on websites you visit — only Google's own ads.
- You can also delete your Google Ad interests list and remove individual topics Google thinks describe you.
- Ads personalization will turn back on automatically if you do not visit your Google Account for a long period, so you may need to re-disable it occasionally.
How to turn off personalized ads in your Google Account
Go to myaccount.google.com in your browser and sign in with the Google account you use most often. On the left side, click Data & Privacy. Scroll down until you see the section labeled Ad settings and click it.
You will see a toggle for Ads Personalization. Click the toggle to turn it off. Google will ask you to confirm — click the confirmation button. The change takes effect immediately, though it may take a few hours for Google's systems to stop serving you personalized ads everywhere.
If you have multiple Google accounts, you will need to repeat this step for each one. The setting does not carry across accounts.
What happens when you turn off personalized ads
After you disable personalized ads, Google stops building a profile of your interests based on your YouTube watch history, Gmail content, search history, and websites you visit that have Google tracking code. You will still see ads, but they will be based on your current context — if you search for "running shoes," you might see ads for running shoes, but Google will not remember that search next week and show you shoe ads on unrelated websites.
The ads you see may be less relevant to you, which means you might see ads for products you have no interest in. Some people find this annoying; others prefer it. There is no performance cost to you — pages load at the same speed, and your account works exactly the same way.
Removing topics Google thinks describe you
Even with personalized ads turned off, Google maintains a list of topics and interests it thinks apply to you based on your activity. You can see this list and remove items from it, which gives you more control over what Google knows about you even if you leave personalized ads on.
In the same Ad settings section where you toggled personalized ads, scroll down to find Your topics. This shows categories like "Sports," "Technology," or "Home & Garden" that Google has inferred from your activity. Click the X next to any topic you want to remove. You can also click a topic to see why Google assigned it to you — it will show you the websites or searches that triggered it.
Removing topics does not prevent Google from re-adding them if you continue the activity that triggered them. If you remove "Sports" but then watch ten basketball videos on YouTube, Google will add "Sports" back to your list.
Controlling ads on YouTube specifically
YouTube has its own ad controls separate from your main Google Account settings. Go to youtube.com, click your profile picture in the top right, and select Settings. Click Privacy on the left side, then find the option for Manage all Google Ads personalization settings. This takes you to the same Google Account settings page described above.
You can also control which ads you see on YouTube by clicking the three dots next to any ad and selecting Don't show ads like this or Report ad. This does not turn off personalized ads globally, but it tells YouTube you do not want to see that specific ad or category of ads again.
What personalized ads settings do not control
Turning off personalized ads in your Google Account only affects ads served by Google itself. It does not stop other companies from tracking you or showing you personalized ads. If you visit a website that has a Facebook pixel or Amazon tracking code, those companies can still build a profile of you and show you targeted ads on their own platforms.
To limit tracking by other companies, you would need to use browser privacy settings, install a privacy extension, or adjust settings in individual services like Facebook, Amazon, and Microsoft. Your Google Account settings do not reach those systems.
Why Google might re-enable personalized ads
Google's systems will automatically turn personalized ads back on if you do not sign into your Google Account for an extended period — typically several months. This is a technical reset rather than a deliberate choice by Google, but it means you may need to check your settings periodically and re-disable personalized ads if you notice they have been turned back on.
You can check your current setting anytime by returning to myaccount.google.com, going to Data & Privacy, and opening Ad settings. The toggle will show you whether personalized ads are currently on or off.
Frequently Asked Questions
Will turning off personalized ads make Google services slower or break anything?
No. Disabling personalized ads does not affect how fast pages load, how search works, or any other function of Google services. The only change is the type of ads you see — they will be less tailored to your interests, but the services themselves work identically.
Can I turn off personalized ads just on YouTube or Gmail without affecting other services?
No. The personalized ads setting is global across your Google Account. If you turn it off, it affects ads on YouTube, Gmail, Google Search, and any other Google service you use while signed in. There is no way to disable it for one service only.
If I use Google in a private or incognito window, does that avoid personalized ads?
Private browsing windows do not sign you into your Google Account automatically, so Google cannot use your account history to personalize ads in those windows. However, if you manually sign in while in a private window, personalized ads will work the same way they do in a regular window. Private browsing is not a substitute for disabling personalized ads in your account settings.
What is the difference between disabling personalized ads and deleting my Google search history?
Deleting your search history removes the record of past searches from your account, but it does not stop Google from building a new profile going forward. Disabling personalized ads stops Google from using your history (old or new) to target ads, but the history itself remains in your account unless you delete it separately. You can do both if you want maximum control.
Do I need to disable personalized ads on my phone separately from my computer?
No. The setting in your Google Account applies across all devices where you are signed in — phones, tablets, computers, and smart TVs. Changing it once changes it everywhere. However, if you use different Google accounts on different devices, you will need to adjust the setting for each account separately.
