Content keyword targeting uses keywords in Google Display and video campaigns to place your ads on websites, apps and YouTube videos whose content is about those words. It is a form of contextual targeting: the ad follows the subject of the page, not something the person typed into a search box.
How content keyword targeting works
You add a list of keywords to an ad group in a Display campaign or a video campaign. Google scans pages and videos across the Display Network and YouTube, works out their themes, and shows your ad where the content matches. A garden landscaper adding patio ideas, garden design and raised beds would appear on gardening blogs, home improvement articles and how-to videos on those subjects.
Display keywords are treated as themes rather than exact matches, so match types and close variants do not apply the way they do in search. At the time of writing (October 2026), Google Ads lets you choose whether keywords should target content only, or also people who seem interested in those themes. The content setting is the one that keeps the ad tied to the page.
It is worth separating this from custom segments, which also start from a list of keywords. A custom segment uses those words to describe a kind of person, based on what they have searched for or browsed, and then follows that person around the web. Content keyword targeting describes a kind of page. The two can be used together, but they answer different questions and should be judged separately.
When you combine keywords with other targeting, such as topic targeting or placements, the ad generally has to satisfy both, which narrows reach. Optimised targeting, if switched on, is designed to find people beyond the signals you give it, so decide deliberately whether you want it.
Why it matters
Contextual targeting does not rely on tracking individuals, which makes it a useful option as cookie-based audiences shrink and as more UK visitors decline non-essential cookies under PECR consent rules. Someone reading an article about loft conversions is in a relevant frame of mind, whatever their browsing history.
It also gives you more say over where a brand appears than broad audience targeting. For a business with a narrow specialism, a well-chosen keyword list can find the small corners of the web where its buyers read.
Common mistakes
- Copying a search keyword list straight across. Search keywords describe what people want to buy; content keywords should describe what they read about.
- Using very short, ambiguous words that match unrelated content, such as bridge for a dental practice.
- Leaving optimised targeting on by default without deciding whether wider reach suits the campaign.
- Never checking where the ads appeared, so low-quality sites and children’s apps soak up budget.
How to act on it
Write ten to twenty keywords that describe the subjects your customers read about, each closely related to the others, and keep one theme per ad group. Decide whether you want content-only targeting and set it deliberately, along with optimised targeting.
Before launch, set the account’s content exclusions to rule out sensitive categories you would not want your brand next to. If your offer needs a proper browsing session to make sense, plan to watch app placements closely once the campaign is live. Give each ad group its own creative that suits the subject of the pages it will appear on: an ad that echoes the article’s theme tends to earn more attention than a generic one.
After a week or two, open the “Where ads showed” report, add poor sites and apps as placement exclusions, and refine the keyword list. Display and video work sits inside my PPC management service, where I review placements as part of the routine checks.
