How do URL placements work in Google Ads, from whole domains to single pages?
Part of Google Ads placements
The short answer
A URL placement tells Google Ads where an ad group may serve on the Display Network. A bare domain is the widest entry, a subdomain or section path is narrower, and a full page URL is the narrowest. Use a domain when the whole site fits, and a page or section when only one part matches the brief.
Key takeaways
- Google says a placement can be a website, a specific page on a site, an app, video content or an individual ad unit, so the URL you type sets the scope.
- Google documents domain, subdomain, directory and page matching in detail for exclusions; for targeted URLs it publishes no equivalent table, so confirm scope in reporting.
- The Google Ads API caps placement URLs at 250 characters and two levels of depth, which rules out long tracking strings and deep paths.
- Page placements trade reach for precision, so they fit as a small set beside domain placements, not as a whole plan.
What is the difference between a domain and a page placement?
Google's placement targeting page (opens in a new tab) says a placement can be a website or a specific page on a site, a mobile app, video content, or even an individual ad unit. In practice the difference between a website placement and a page placement is the string the planner types. A bare domain such as example.com asks Google Ads to treat the whole site as eligible. A full address such as example.com/guides/first-home.html asks for one document and nothing around it.
Definition
- URL placement
- A website placement entered as a web address in a Display or Demand Gen ad group. Its scope runs from a whole domain down to one page, depending on how much of the address is entered.
The Google Ads API reference says the same thing in its own terms. The PlacementInfo criterion has one field, url, described as the URL of the placement. Nothing marks an entry as a domain or a page: the scope comes from the address alone, so two planners loading the same publisher can get very different delivery.
| Entry level | Example entry | What it asks for | Example use on a plan |
|---|---|---|---|
| Domain | example.com | The whole site; for exclusions Google says a bare domain also covers its subdomains | A specialist publisher whose whole site fits the brief |
| Subdomain | travel.example.com | Only the pages served from that host | A large media group that runs a vertical on its own host |
| Section path | example.com/recipes | Pages under that directory | A broad site with one section that matches the brief |
| Single page | example.com/recipes/sourdough.html | One document only | An evergreen guide that keeps earning readers |
How do subdomains match in Google Ads placements?
Google's clearest statement on subdomain matching is on its exclusions page (opens in a new tab), which says excluding a domain prevents ads from appearing on any page on or within that domain, while an entry such as www.example.com covers only that subdomain and its directories. Google's help pages for targeted placements, checked October 21, 2026, do not publish an equivalent table. The safest working assumption is that scope follows the same logic, and the safest practice is to confirm it in reporting rather than rely on it.
Two patterns cause surprises. A list built by copying the address bar fills with www entries that may cover less than the whole site. And some news groups run sports, events or classifieds on separate hosts: if the brief wants the newsroom only, enter that subdomain; if it wants everything, enter the bare domain.
Choosing the entry for a publisher with several hosts
- List the publisher's hosts. Open the homepage and note every distinct host its menus link to, such as news, events or shop.
- Read a few pages on each host. Decide host by host whether the content fits the brief.
- Enter the bare domain when every host fits. Drop the www prefix so the entry is not limited to one host.
- Enter one line per host when only some fit. Add each fitting subdomain separately and leave the others out.
- Exclude the hosts that must never serve. A targeted subdomain does not block its siblings if another targeting method reaches them, so add an exclusion for any host the client rejected.
When should you target a specific URL instead of a whole site?
A page placement earns its place when one document fits the brief far better than the site around it, such as an evergreen buying guide on a general lifestyle site or a long running explainer on a regional news site. If the planner could not defend the rest of the site to the client but is confident about this page, target the page.
| Situation | Better entry | Why | Watch for |
|---|---|---|---|
| Recent articles fit the brief throughout | Domain | Reach grows with the site's output | A section the client would object to |
| One section fits, the rest is off topic | Section path | Keeps the theme without picking pages one by one | Section pages that move to new paths |
| One evergreen page fits, the site does not | Single page | Precise context the client can open and read | Low impression volume and page redesigns |
| The page is news that will age in days | Neither | The context will change before the flight ends | Spending effort on a URL that stops getting readers |
Google's add and edit placements page tells advertisers to click Enter in the placement box, then enter their placement URLs. The Google Ads API criteria guide limits placement URLs to 250 characters and two levels of depth, so strip query strings, campaign tags and anchors before loading a page URL.
Before adding a page URL as a placement
- The page carries ads today: open it on a phone and a desktop and find the ad slots.
- The address is the canonical form, without query strings, tracking tags or anchors.
- The address is under 250 characters and no deeper than two levels below the domain.
- The page is evergreen enough to keep readers for the whole flight.
- The same ad group holds no topics or display keywords that would widen it back to the network.
Do page placements limit reach too much?
They can, and the planner makes that trade on purpose. One page receives a fraction of a site's visits, and Google's placement targeting page says advertisers still compete in the auction for placements they choose, and popular sites may need higher bids to get impressions. A plan of page URLs alone can look precise and deliver almost nothing.
The fix is structure. Keep page and section placements in their own ad group so their delivery is visible, pair them with a domain level ad group for publishers that fit throughout, and review early in the flight. If the page ad group barely serves, widen it one step at a time, rereading the content at each step.
How do domain and page placements show up in reports?
The Google Ads API documentation on placement views (opens in a new tab) separates three levels: the managed view for placements an advertiser targets (Content then Placements), the group view for where ads served by domain, channel or app, and the detail view for specific URLs, matching View details in Where ads showed.
That split explains why a page placement looks different across reports. A page placement appears in the Placements report as the URL the planner entered, while Where ads showed groups delivery under the publisher's domain. Only View details shows which pages carried the ads. Google's Where ads showed help page (opens in a new tab) also warns that placements appear only above minimum thresholds of impressions or interactions, so a quiet page URL may not show at all.
What does a URL placement plan look like on a real brief?
Fictional example
A residential solar installer in Colorado and Utah
A fictional installer of rooftop solar panels in Denver and Salt Lake City wants Display ads beside homeowner guides to energy bills and roofing, in English. Candidates include two specialist home energy publishers, a large regional news site and a general lifestyle site with one well read guide to solar tax credits.
The specialist publishers go in as bare domains, because nearly every recent article fits. The news site runs real estate on its own subdomain, so that host goes in alone. On the lifestyle site only the tax credit guide fits, so its canonical page URL, stripped of tracking tags, goes in a separate ad group.
Neither ad group holds topics or display keywords. After the first week, View details in Where ads showed confirms the page group served on the guide itself, and the planner records the result beside the approved list.
How does PlacementGraph decide whether a whole site fits a brief?
How do you exclude a single page without losing the whole site?
Enter the full address of that page as a placement exclusion. Google's exclusions page lists an individual page, such as www.example.com/index.html, as an entry that excludes only that page. Google also states that subpage exclusions do not work on the Search Partner Network, and a page exclusion does nothing for the next article on the same theme. The placement exclusions guide covers levels, lists and limits.
Removing a targeted page from an ad group is not the same as excluding it. Google's add and edit placements page (opens in a new tab) warns that ads may still appear on a removed placement if the ad group has matching keywords, topics or other phrases. For more on choosing Display sites in the first place, see the Display Network placements guide, and for reading served rows, the where ads showed guide.
Frequently asked questions
Should I type http or https at the start of a placement URL?
It does not change scope. The scheme does not alter which pages a placement covers, and the Google Ads API example placement uses http. Stripping the scheme and the www prefix from every row before import keeps the list consistent and easy to check.
Can I target a whole section of a site with one entry?
A directory path such as example.com/recipes expresses a section. Google documents directory scope for exclusions, where the entry covers that directory and its pages. For targeting, confirm what served with View details in Where ads showed after the first days, and keep the path within the API's two level depth limit.
Do URL placements work for YouTube?
No. YouTube placements are channels and videos, chosen by channel or video rather than by web address. URL placements are for websites on the Display Network. Google's placement pages treat YouTube channels and videos as their own placement types, so a YouTube plan needs its own list, not a set of youtube.com addresses.
What should I do when a publisher moves a page I targeted?
Treat the old entry as stale. A page placement names one address, and Google does not document that it follows a new path. When View details stops showing the page, find the new canonical address, reread it, and replace the entry in the ad group and the approved list.
