What are display keywords in Google Ads, and how do they match?
Part of Google Ads placements
The short answer
Display keywords, which Google calls Display or Video keywords, are words added to an ad group so ads can show on Display Network pages and YouTube videos whose central theme matches them. Google reads each page's text, language, links and structure to find that theme, so a page can match without using the exact word. Match types do not apply.
Key takeaways
- A display keyword describes content, not a search: Google matches it to the central theme it finds on each page or video.
- Google advises against match types for contextual targeting, suggests 5 to 10 keywords per ad group on its contextual page, and keeps each keyword to 2 or 3 terms.
- Keywords beside placements widen an ad group to content matching either; an audience layer on top narrows it again.
- On the Display Network keyword targets are fully supported, while on YouTube Google says keyword and topic targeting act as a hint.
- With optimized targeting on, keywords in a Display ad group can become signals, and Google may reduce or stop serving on them.
What are display keywords in Google Ads?
Definition
- Display or Video keyword
- A word or short phrase in a Display, Video or Demand Gen ad group that tells Google which subject the surrounding content should be about. Google calls this contextual targeting and manages it on the Content page with topics and placements.
The same word does different work in different campaign types. In a Search campaign, a keyword is compared with what a person types. In a Display or Video ad group, it is compared with what a page or video is about. Google's contextual targeting page (opens in a new tab) says the system analyzes the content of each webpage to determine its central theme, then matches ads to it.
| Where the keyword lives | What it is compared with | Match types |
|---|---|---|
| Search campaign keyword | The search query a person types | Yes: broad, phrase and exact |
| Display or Video keyword (content) | The central theme Google finds on a page, app or video | No: Google advises against match types for contextual targeting |
| Custom segment keyword | A description of people's interests, entered with URLs and apps to build an audience segment | No: it defines an audience, not content |
The last row matters for planners who read old guides. Google's Demand Gen audiences overview (opens in a new tab) describes custom segments built from relevant keywords, URLs and apps, which find people, not pages. Google Ads Editor's Display settings page (opens in a new tab) still separates content keywords, matched to the page being viewed, from audience keywords, shown to people based on recent browsing history. Only the content kind is placement adjacent.
How do content keywords match web pages?
Google's page on how contextual targeting works (opens in a new tab) lists the factors it reads. For a Display Network webpage they are the text, the language, the link structure and the page structure. For a YouTube video they are text, metadata, visual content, audio content and channel information. From those, Google determines a central theme for each page or video and compares it with the keywords in the ad group.
Writing display keywords that match the right pages
- Name the subject, not the shopper. Write the words a page about the subject would use, such as "puppy vaccination schedule", not words about the buyer.
- Keep each keyword short. Google suggests 2 or 3 terms per keyword so targeting stays relevant without becoming too narrow.
- Keep each ad group small. Google's About contextual targeting page (opens in a new tab) recommends approximately 5 to 10 keywords per ad group; split a long list into themed ad groups.
- Skip match types. Google says match types offer no advantage for contextual targeting and can confuse attribution in reporting.
- Test on real pages. Before launch, search for pages that should match and pages that should not, and ask whether each one's main subject fits the keyword.
How do keywords combine with placements in an ad group?
Google treats content targeting types as alternatives within one ad group. Its page on combining content targeting types (opens in a new tab) says ads show on content that matches any of the topics, placements, or Display or Video keywords targeted. A keyword beside a list of 20 sites adds every page on the network whose theme matches the keyword; it does not confine the ad to keyword pages on those 20 sites.
| Change | Effect on reach | Source |
|---|---|---|
| Add a keyword to an ad group that already has placements | Wider: content matching either qualifies | Combining content targeting types (opens in a new tab) |
| Add more keywords of the same kind | Wider: adding items within a targeting type broadens reach | Targeting for Display campaigns (opens in a new tab) |
| Add an audience layer on top of content targeting | Narrower: each new layer of targeting generally narrows potential reach | Targeting for Display campaigns (opens in a new tab) |
| Leave optimized targeting on in a Display ad group | Can move beyond the keywords: they act as signals, and serving on them may drop if better traffic is found | About optimized targeting (opens in a new tab) |
The last row is easy to miss. Google's optimized targeting page (opens in a new tab) says optimized targeting is turned on automatically, that Display campaigns can use keywords and topics as signals, and that it may reduce or stop serving on those signals. It also says it respects existing brand safety settings such as content exclusions, and that it can be turned off in ad group settings. For Video campaigns, the same page says placements are not used as a signal and ads show only on the placements provided.
When should you use keywords instead of placements?
Keywords and placements answer different planning questions. A placement says where; a keyword says about what. Neither is better in general, and each has a cost the planner should accept on purpose.
| Question | Display keywords | Placements |
|---|---|---|
| What the buyer controls | The subject of the content | The exact sites, apps, channels and videos |
| Strengths | Reaches pages on the subject across many sites, including sites the team has never heard of | Every location can be reviewed for quality, suitability and selling path before launch |
| Weaknesses | Sites are known only after impressions run, and a word with two meanings can pull in the wrong subject | Reach is capped by the list, and a small list may not spend its budget |
| Upkeep | Reading where ads showed and excluding poor sites as they appear | Reviewing and refreshing the list itself |
| Fits best | Discovery tests and subjects spread thinly across general sites | Signed off lists, regulated categories and briefs with strict suitability needs |
Before adding display keywords to a placement plan
- The keywords sit in their own ad group, apart from the reviewed placements, with a set budget share.
- Each keyword was tested on real pages for a second meaning that could pull in the wrong subject.
- Optimized targeting is set on purpose, on or off, for the keyword ad group.
- Account level exclusions and content suitability settings are in place before launch.
- A weekly read of where ads showed is scheduled, with good finds moved into the reviewed list.
Which campaign types still support content keywords?
Content keywords have lost ground as Google folded conversion focused video buying and then Display campaigns into Demand Gen. The table below follows Google Ads Help as checked in October 2026 and names the surface each statement covers.
| Campaign type | Content keywords | Surface notes |
|---|---|---|
| Display | Yes, per ad group on the Content page | Display Network pages: Google says keyword and topic targets in Demand Gen and Display campaigns allow ads to appear on any page on the Display Network |
| Demand Gen | Yes, as contextual targeting with topics and placements | YouTube: keyword and topic targeting act as a hint; Discover and Gmail do not support contextual targeting and do not serve at all when topic or keyword inclusions are enabled (help (opens in a new tab)) |
| Video (awareness and consideration) | Yes | YouTube: keyword and topic targets help optimize as hints, while placement targeting is fully supported |
| Video campaigns that drive conversions | No | Content targeting was removed from these campaigns from early 2023, and Video action campaigns were upgraded to Demand Gen by April 2026 (help (opens in a new tab)) |
What does a display keyword ad group look like on a real brief?
Fictional example
A veterinary clinic network in Iowa and Nebraska
A fictional network of veterinary clinics in Des Moines, Omaha and Lincoln runs an English Display plan on 30 reviewed pet care and local family sites. The client wants more reach on new puppy and kitten care without loosening its standards for the reviewed list.
The buyer builds a separate ad group with eight keywords of two or three terms each, such as puppy vaccination schedule and kitten first vet visit. Testing on real pages shows that one candidate, pet scan, also matches pages about PET scans in human medicine, so it is replaced with a clearer phrase. Optimized targeting is turned off in the keyword ad group so the keywords are not treated as signals.
The placement ad group keeps the 30 reviewed sites with no keywords beside them. Each week the buyer reads where ads showed for the keyword ad group, excludes sites that fail the same review the 30 passed, and adds sites that pass to the reviewed list.

Frequently asked questions
What happens to display keywords when a Display campaign moves to Demand Gen?
Google's migration page lists contextual targeting as supported, along with performance history back to 42 days. It also lists blockers: manual CPC bidding, shared budgets and ad group bid modifiers or exclusions must be changed first, and Observation settings for non demographic targeting are not supported. Check each keyword ad group against that list before migrating.
What is an audience keyword in Google Ads Editor?
Google Ads Editor's Display settings page describes audience keywords as showing ads to people based on their recent browsing history, unlike content keywords, which match the page being viewed. For a placement plan built on content, only content keywords keep the targeting tied to pages. Check which setting an inherited ad group uses before reusing it.
Can I paste my Search keyword list into a Display ad group?
It can be added, but the two do different jobs. Search keywords describe what people type, with match types, while display keywords describe what a page is mostly about, with no match types. Rewrite the list as short subject phrases of two or three terms and test them on real pages before launch.
Do display keywords reach apps as well as websites?
They can. Google's page on combining content targeting types gives an example of keyword targeting reaching sites, apps and videos about a subject, and the where ads showed report lists apps beside websites. A plan meant only for websites needs app exclusions set before launch, then a check of the report in the first week.
