Definition:
The Google Ads Search Network is the set of websites and surfaces where ads associated with searches may appear. It includes Google search results and, when campaign settings allow it, search partner sites.
It is not a separate platform from Google Ads and does not include every Google advertising placement. It is an advertising inventory primarily associated with queries and other search contexts.

How the Search Network works
When someone performs a search, Google Ads identifies which ads may participate according to campaign settings. Keywords, match types, location, language, device, and other signals help determine eligibility.
Eligible ads enter an auction. The bid alone does not decide whether an ad appears or its position: estimated quality, the expected effect of assets, search context, and applicable thresholds also contribute. An active keyword therefore cannot guarantee impressions for every related query.
The user’s query and the keyword do not have to be identical. Match types can cover variants and related meanings, while a negative keyword prevents participation in searches that are not relevant to the campaign.
Search Network inventory
The Search Network can cover several surfaces. Specific availability depends on the format, country, query, and configuration. The following are among its common destinations:
- Google Search: Ads may appear above or below search results and in other enabled areas of the page.
- Google Shopping: Certain ads may appear alongside product search results and experiences.
- Google Images: Compatible ads may be integrated into visual search contexts.
- Google Maps: Some campaigns can show ads related to local searches in Maps and its application.
- Google Play: Eligible formats may appear alongside search results within Google Play.
- Search partners: Associated websites and services show ads alongside their results; they may include non-Google properties and certain Google surfaces.
Partners extend reach, but their traffic should be analysed separately. Campaign settings allow the partner network to be included or excluded as a group; advertisers do not ordinarily select each website individually through a placement list.
Google Ads documentation maintains the operational list of surfaces and formats, which may change as the product evolves.
Search Network targeting
Presence on the network is controlled from a Search campaign. Its configuration combines several selection criteria:
- Queries: Keywords and match types delimit the searches in which an ad may participate.
- Location: Geographic targeting uses the person’s presence or interest according to the selected option.
- Language: A campaign can target ads according to the languages Google estimates that a person understands.
- Audiences: Segments may be used for observation, adjustment, or restriction depending on the available setting.
- Scheduling: Time, devices, and other settings modify when and how an ad may be displayed.
Targeting does not replace the relationship between the query, ad, and landing page. A relevant message may generate the click, but the page must address the intent and comply with policies for the experience to remain coherent.
Performance measurement
Performance is analysed through impressions, clicks, CTR, cost, conversions, and value according to the configured objectives. These metrics represent different stages: a good CTR does not prove profitability by itself, and a conversion can only be interpreted when the action and its measurement are correctly defined.
The search terms report shows some of the queries that triggered ads and helps identify new negatives, variations in intent, or groups that need restructuring. It does not necessarily include every query because Google applies privacy and volume thresholds.
Performance from Google Search and partners should also be separated. Differences in volume, click-through rate, cost, or conversion may justify configuration changes, but they require sufficient data and do not prove that the entire partner network is lower quality.
Optimisation means adjusting queries, ads, bids, budget, and pages using measured results. Changing many variables simultaneously makes it harder to attribute each effect to a specific action.
Differences from the Display Network
The Display Network distributes ads across websites, applications, and other surfaces mainly according to audiences, content, and placements. The Search Network responds primarily to queries or search contexts and therefore tends to reflect more directly expressed intent.
This does not make one network better than the other. Each supports different formats, controls, and objectives. Some automated campaigns may use several inventories, but that does not mean all their ads belong to the Search Network.
The network should not be confused with the work of a Google Ads agency, organic search, or a specific campaign. It defines where ads appear; the campaign determines how they participate, and the auction decides each individual opportunity.
