Setting up line items in Google Ad Manager for third-party advertising is essential for publishers who want to serve ads from multiple networks or demand sources.
Line items act as instructions that define how, when, and which ads from third parties get displayed on a website or app, ensuring smooth integration and revenue optimisation.
Without proper setup, third-party ads may not deliver correctly or compete effectively with other ads.
To successfully use third-party advertising, Google Ad Manager needs to be configured to accept and manage these line items.
This involves selecting the right type of line item, adding necessary tags, and setting priorities and targeting rules.
Each step helps maintain control over ad delivery and guarantees that ads meet the site’s requirements and audience preferences.
Key Takeways
- Line items control the delivery of third-party ads in Google Ad Manager.
- Proper configuration ensures ads compete and display correctly.
- Monitoring line item performance helps increase ad revenue.
Understanding Line Items in Google Ad Manager
Line items in Google Ad Manager define how ads are delivered across an ad inventory.
They determine the timing, targeting, and creative details of ads while managing impressions and clicks.
Each line item connects to a specific ad order, making it crucial for precise campaign control.
What Are Line Items?
A line item is a set of instructions in Google Ad Manager that controls how ads should run.
It specifies where and when ads will appear, the number of impressions or clicks to serve, and which ad creatives to use.
Line items act as contracts between the advertiser and publisher, setting the terms for campaign delivery.
They ensure the ad server knows exactly how to manage ad inventory according to advertiser needs.
Types of line items vary by priority and inventory type.
For instance, some are guaranteed impressions while others fill leftover space.
Understanding these types helps optimise ad delivery.
Key Components of a Line Item
Key components include:
- Start and end dates: Define the campaign timeline.
- Ad units: Specify the locations in the inventory where ads appear.
- Impression or click goals: Determine how many times an ad should be shown or clicked.
- Targeting criteria: Allow ads to reach specific audiences based on demographics or behaviours.
- Creative assets: The actual ads that deliver the message.
These elements work together to control budget pacing and delivery speed.
The default pacing setting evenly distributes impressions across the campaign duration unless altered.
How Line Items Interact with Ad Orders
Line items are always part of an ad order in Google Ad Manager.
An order groups multiple line items that share a common goal or advertiser.
This structure helps organise campaigns under one contract.
Each line item operates separately but contributes to the overall order’s success.
Orders allow publishers and advertisers to manage multiple creatives, formats, and targeting strategies in one place.
This relationship ensures efficient tracking and reporting.
Changes to a line item affect only that segment of the campaign, while the order records total progress.
More details about line items and orders can be found at about line items in Google Ad Manager.
Types of Line Items for Third-Party Advertising
Line items in Google Ad Manager define how ad campaigns run, how ads compete, and what guarantees exist for delivery.
Different types control priority, pricing, and inventory access, allowing publishers to manage both direct and third-party advertising effectively.
Guaranteed Line Items Explained
Guaranteed line items include sponsorship and standard types.
Sponsorship line items reserve most or all of the inventory during a specific time, offering a fixed number of impressions or clicks.
They often ensure exclusivity and priority over other campaigns.
Standard guaranteed line items come with specific delivery goals and fixed budgets.
Advertisers are guaranteed a minimum level of impressions or ad delivery within a set period.
These line items take precedence over non-guaranteed types, ensuring advertisers’ objectives are met reliably.
Both sponsorship and standard line items allow for detailed targeting, including ad units and devices.
This gives advertisers confidence in reaching their audience without competition from third-party networks or exchanges.
Non-Guaranteed Line Items Overview
Non-guaranteed line items are flexible options that do not guarantee impressions but compete for inventory based on rules like price or priority.
This category includes network, price priority, and bulk line items.
These are often used for remnant inventory that guaranteed campaigns do not fill.
Network line items work with third-party ad networks and receive lower priority than guaranteed orders.
Price priority line items focus on delivering ads by the highest bid price, suitable for header bidding or ad networks where price dictates delivery.
Bulk line items serve as low-priority options with minimal controls, typically for experimental or broad campaigns.
Non-guaranteed line items allow publishers to monetise unsold inventory by accepting bids from multiple sources without strict delivery commitments.
Programmatic Line Item Categories
Programmatic line items involve automated buying and selling, including options like Ad Exchange, AdSense, and preferred deals.
These line items use dynamic pricing and real-time bidding to allocate inventory.
Ad Exchange and AdSense line items represent demand from Google’s platforms, and both are available only to accounts enabled for third-party services.
They compete at a fixed priority level, usually lower than guaranteed line items but higher than bulk.
Preferred deals allow advertisers to negotiate private pricing and priority delivery before inventory goes to open auction.
These line items provide an intermediate option between direct guaranteed campaigns and open programmatic auctions.
Each programmatic category helps publishers tap into external demand while maintaining control over pricing and inventory allocation.
More detailed setup instructions are available in the line item types and priorities guide.
Preparing Google Ad Manager for Third-Party Line Items
Before adding third-party line items, Google Ad Manager must be set up to handle demand from various sources.
This involves organising your ad units and inventory precisely, connecting demand partners, and enabling modern bidding methods to maximise revenue and control.
Configuring Ad Units and Inventory
Ad units define where ads will appear on a website or app and must be carefully organised in GAM.
Publishers should create ad units that match their site’s layout and traffic patterns, grouping similar placements under clear, logical names.
Ad inventory should be categorised by size, type, and format (e.g. banner, video).
This allows accurate targeting when setting up line items.
Steps to configure:
- Create ad units with descriptive names.
- Include sizes supported by demand partners.
- Set up placements and hierarchies for easy management.
Proper configuration helps third-party ads deliver in the right spot, reducing errors and improving fill rates.
For more details on setting up ad units, see Google Ad Manager Help.
Setting Up Demand Partners and Ad Exchange Accounts
To accept third-party ads, demand partners like Google Ad Exchange (AdX) must be authorised.
Publishers need:
- An active Ad Exchange account linked to GAM.
- To enable third-party services in the account.
- To connect demand sources or networks that will provide ads.
This ensures GAM can route ad requests to the right demand and manage competition across partners.
Demand partner setup includes granting access, defining targeting parameters, and aligning payment terms.
Without proper connection and permissions, ads from third parties will not serve correctly.
Publishers often coordinate with Google representatives or partners for activation and troubleshooting.
More on demand partner types is available at OKO.
Integrating Open Bidding and Header Bidding
Open bidding (also called exchange bidding) allows multiple demand sources to compete in real time within GAM.
It operates server-side, simplifying setup and improving latency.
Header bidding is a client-side method where multiple demand partners bid before the ad server runs.
It often uses Prebid.js to manage bids outside of GAM.
Both methods help increase competition for inventory and maximise revenue.
Key points for integration:
- Enable open bidding in GAM settings and configure demand partners.
- Use Prebid to connect header bidding with GAM through line items prioritised as “network” or “price priority.”
- Monitor auction and CPMs regularly to adjust settings.
Combining open and header bidding can improve fill rates and yield but requires technical coordination.
Google Ad Manager’s integration guides can assist in setup.

Step-by-Step Setup of Line Items for Third-Party Advertising
Setting up line items in Google Ad Manager requires careful attention to detail.
It involves creating line items correctly, linking them to specific orders and ad units, assigning the right creatives, and setting accurate schedules and delivery options.
Each step ensures ads serve as intended and meet campaign goals.
Creating and Naming Line Items
The first step is to create a new line item in the ad server.
A clear, descriptive name helps keep campaigns organised, especially when managing multiple line items across orders and ad units.
The name should include key details such as campaign type, target audience, or third-party network for easy identification.
When creating a line item, select the correct type—such as network, sponsorship, or price priority—depending on how it will compete with other line items.
Setting the right priority affects how often the ads serve.
Make sure to specify whether the line item is guaranteed or non-guaranteed.
This initial setup helps control ad delivery and billing.
Linking Line Items to Orders and Ad Units
Once the line item is created, it must be linked to an order.
Orders group line items for specific campaigns or clients, ensuring billing and reporting are accurate.
Each line item belongs to only one order but can target multiple ad units.
Targeting ad units correctly is essential.
This defines where the ads will appear on the publisher’s site or app.
Targeting settings can include placements, device types, and geography.
Accurate targeting maximises the relevance of ads and improves campaign performance.
Assigning Ad Creatives to Line Items
Ad creatives are the actual ads displayed to users.
After setting up the line item, the appropriate creatives must be assigned.
This can include images, video, or HTML5 ads, depending on campaign needs.
Google Ad Manager allows multiple creatives per line item.
This lets the system rotate or optimise ad delivery based on performance.
It is important to verify that creatives meet size, format, and policy requirements.
Assigning the right creatives ensures the ads display correctly and maintains user experience.
Scheduling and Delivery Settings
Scheduling controls when a line item will deliver ads.
Start and end dates should be set based on the campaign timeline.
Additionally, delivery settings such as impressions caps and daily limits prevent overserving.
Delivery pacing must be chosen carefully: standard pacing distributes impressions evenly over the campaign duration, while accelerated pacing serves ads as fast as possible.
For third-party advertising, it’s common to use capping to control ad frequency and avoid overexposure to the same users.
Monitoring these settings regularly helps maintain campaign goals and budget limits.
For a complete breakdown of line item settings, consult detailed Google Ad Manager line item setup guides.
Advanced Targeting and Pricing Strategies
Effective ad delivery depends on carefully selecting who sees the ads and how much advertisers pay.
Strategies include setting clear targeting rules, managing pricing with unified controls, using data owned by the publisher, and fine-tuning how ads compete for space.
These elements work together to ensure campaigns reach the right audience while maximising revenue.
Defining Targeting Criteria and Audience Segments
Setting precise targeting criteria allows for ads to reach specific groups based on location, device, or user behaviour.
Audience segments can include categories like age, gender, interests, or past interactions with the website.
Using detailed demographics and remarketing data helps improve campaign relevance.
Publishers can combine several targeting criteria for better accuracy.
For example, they might target users in a particular city who previously visited certain pages and are browsing on mobile devices.
This layered targeting narrows the audience but increases the chance of engagement.
Using audience segments also supports dynamic bidding, where advertisers pay more for highly specific targets.
This setup improves campaign performance by focusing on the most valuable users.
Applying Unified Pricing Rules
Unified pricing rules standardise how bids are handled across multiple ad exchanges and networks. They set minimum bid levels, price adjustments, or deal-specific rates to align with the publisher’s revenue goals.
By applying these rules, publishers can prevent low bids from winning impressions too cheaply. It also makes managing multiple line items easier because pricing policies apply consistently.
Unified pricing can be configured to change based on the day, user device, or audience segment. For example, prices might be higher during peak hours or for premium segments.
This dynamic approach ensures pricing reflects demand conditions.
Utilising First-Party Data
First-party data comes directly from the publisher’s own audience and is highly valuable for targeting. It includes information collected through website interactions, newsletters, or user registrations.
Using this data allows publishers to create custom audience segments that provide more precise targeting. For instance, frequent buyers or newsletter subscribers represent valuable groups advertisers want to reach.
Integrating first-party data with line items improves campaign effectiveness by combining unique insights with broader third-party data. It also supports privacy rules better since first-party data is collected with user consent.
Dynamic Allocation Settings
Dynamic allocation controls how Google Ad Manager decides which line item serves an ad when multiple campaigns compete for the same slot. It allows non-guaranteed line items to compete with guaranteed ones based on price.
This system helps maximise revenue by letting higher bidders win impressions even if they are non-guaranteed campaigns.
Publishers must set minimum prices and priorities to maintain control. For example, they can ensure direct deals always take precedence but allow programmatic buys to fill leftover inventory.
Dynamic allocation is key for balancing advertiser demand and optimising yield across different sources.
For more details on integrating pricing and targeting settings, see the guide to setting custom target CPM and unified pricing rules in Google Ad Manager.
Optimising and Monitoring Line Item Performance
Effective line item performance relies on careful tracking, timely adjustments, and efficient management. Monitoring key metrics such as impressions, clicks, and advertising revenue helps identify trends and issues.
Adjusting delivery settings and managing line items in bulk ensures campaigns reach their target and perform as expected.
Tracking Impressions, Clicks, and Ad Revenue
Tracking impressions shows how often ads are viewed. Clicks indicate user engagement with the ads.
Both are essential for understanding audience interaction. Advertising revenue reveals the financial success of campaigns.
In Google Ad Manager, these metrics are available through detailed reports. Publishers can set up custom reports to monitor daily or weekly trends.
Clear visibility into impressions, clicks, and revenue helps in spotting underperforming line items or revenue drops early. This allows quick responses.
Using consistent tracking also helps compare performance between different line items. This keeps optimisation efforts data-driven.
Adjusting Performance and Delivery
When line items underperform, adjusting delivery pacing and targeting is key. Line item types can be set to reserve impressions or be optimized for revenue.
Modifying pacing rates controls how quickly impressions are served. Advertisers can use Google Ad Manager’s optimisation features for CTR or revenue improvements if the line items meet eligibility rules.
This automatic adjustment improves ad delivery without constant manual changes. Custom curve delivery pacing lets publishers smooth out impression delivery over time to avoid spikes or drops.
Adjusting targeting options such as inventory or audience ensures ads reach the right users. This improves click and revenue rates.
Bulk Management and Troubleshooting
Handling multiple line items manually can be inefficient.
Google Ad Manager supports bulk editing tools to change delivery settings or budgets across many line items simultaneously.
This saves time and reduces errors.
Bulk reports allow performance monitoring of large campaigns quickly.
They help identify common issues in ad serving or pacing.
Common reasons for under-delivery include pacing problems, targeting conflicts, and priority settings.
Regular troubleshooting involves reviewing these factors and adjusting accordingly.
