When do ads perform best
according to Google Ad Manager data?
Timing plays a crucial role in the success of online advertising. Google Ad Manager’s reporting tools allow publishers to identify when their ads perform best, helping to optimize delivery and maximize revenue. From time of day and day of the week to seasonal traffic patterns, GAM data can reveal high-performing ad windows that are often overlooked. In this blog, we explore what the data shows about peak ad performance periods and how you can align your strategy accordingly.
Peak Times of Day for Ad Engagement
Identify high-performing hours based on user activity and CTR trends.
Understanding when users are most active can help maximize the impact of your ad units. Generally, ad engagement peaks during early mornings (7 AM – 9 AM) and evening hours (7 PM – 10 PM), when users are commuting, relaxing, or browsing content on their mobile devices. These time blocks typically show higher click-through rates (CTR) and stronger advertiser competition, especially in lifestyle, news, and entertainment categories.
User behavior varies by region, audience type, and device, but lunch breaks (12 PM – 2 PM) also show noticeable spikes in engagement. For publishers, scheduling high-paying line items or premium creatives during these windows can improve revenue. Leveraging daypart targeting and analyzing historical performance reports in Google Ad Manager can help identify your platform’s unique peak engagement hours and adjust strategies accordingly.
• Early Mornings (7 AM – 9 AM):
Users often check their phones or browse the web during their morning routines or commutes, leading to high engagement and CTRs.
• Lunchtime (12 PM – 2 PM):
This period sees a spike in mobile activity as users take breaks, offering a great window for reaching audiences with snackable or scroll-friendly content.
• Evenings (7 PM – 10 PM):
Prime time for engagement, especially on mobile and entertainment platforms. Users are relaxed and more likely to click on ads during this window.
• Late Nights (10 PM – 12 AM):
While volume may be lower, CTR can be surprisingly strong, especially for lifestyle, health, and personal interest content.
• Work Hours (9 AM – 5 PM):
During standard business hours, desktop traffic dominates, benefiting news, finance, productivity, and B2B content.
• Device-Based Behavior Matters:
Mobile users peak in the morning and late evening, while desktop users are most active during work hours, impacting when and where your ads perform best.
• Use GAM Time-Based Reports:
Leverage hourly performance reports in Google Ad Manager to spot your platform’s top-performing time slots and adjust delivery accordingly.
Best Days of the Week for Ad Revenue
Analyze how weekdays vs. weekends impact impressions, engagement, and earnings.
Ad revenue is not just influenced by time of day—it also varies significantly across different days of the week. Typically, weekdays (Monday to Friday) tend to generate higher impressions and ad earnings, especially for websites focused on business, education, technology, or finance. This is when users are most active online during work hours, leading to stronger engagement and higher competition among advertisers.
On the other hand, weekends often show a drop in ad revenue, especially for B2B or productivity-related content. However, sites centered on entertainment, travel, food, and lifestyle may see a boost on Saturdays and Sundays, as users have more leisure time to explore content. To maximize earnings, publishers should analyze traffic patterns and historical performance, then align their premium campaigns and high-CPM line items with the best-performing days for their specific niche.
• Weekdays (Monday to Friday) Perform Better:
Most websites experience higher impressions and ad revenue on weekdays, especially those related to business, tech, news, education, or finance, as users are more active during working hours.
• Peak Engagement During Midweek:
Tuesdays, Wednesdays, and Thursdays often show the best combination of CTR and CPM, as ad campaigns are in full swing and user activity is consistent.
• Lower Performance on Weekends (for Some Niches):
Saturday and Sunday may see a drop in revenue for B2B or productivity content, as users shift their focus to personal time and leisure activities.
• Lifestyle & Entertainment Sites May Thrive on Weekends:
For niches like travel, food, DIY, and entertainment, weekends can bring higher engagement, as users have more free time to explore and interact with content.
• Ad Budgets Reset on Mondays:
Many advertisers restart budgets early in the week, leading to increased competition and higher CPMs from Monday onwards.
• Fridays Can Be Mixed:
Friday performance varies—some sectors wind down, while others (like e-commerce or weekend event promotions) ramp up ad spend.
• Use GAM Reports to Validate Trends:
Regularly check your Google Ad Manager data to identify which days perform best for your specific audience and niche, then schedule key campaigns accordingly.
Seasonal Trends and High-Demand Periods
Understand how holidays, events, and seasons affect ad performance.
Ad performance often fluctuates with seasonal trends, major events, and holiday periods, all of which can significantly impact impressions, CPMs, and click-through rates. For example, the Q4 holiday season (October to December)—which includes Diwali, Black Friday, Christmas, and New Year—is known for peak advertiser spending as brands compete for visibility. This results in higher ad demand and better revenue opportunities for publishers.
In contrast, Q1 (January to March) can see a dip in ad budgets as companies reset their marketing plans, often leading to lower CPMs and reduced fill rates. Seasonal events like the IPL, school admissions, festival sales, or travel holidays also create temporary spikes in traffic and demand. To make the most of these trends, publishers should plan inventory, adjust pricing rules, and prioritize high-performing ad units during peak periods. Leveraging historical data and aligning with advertiser calendars ensures you are ready to capitalize on every high-demand window.
• Q4 is the Peak Revenue Season:
The months of October to December bring major holidays and shopping events like Diwali, Black Friday, Christmas, and New Year, driving higher advertiser competition and CPMs.
• Q1 Often Sees a Dip:
From January to March, ad spending tends to slow down as brands reset budgets, leading to lower fill rates and revenue for many publishers.
• Festivals and Local Events Drive Short-Term Spikes:
Events like the IPL, festive sales, and cultural holidays generate temporary boosts in ad demand, especially for lifestyle, travel, and e-commerce content.
• Seasonal Content Performs Better in Cycles:
Topics like summer vacations, winter shopping, health resolutions, or back-to-school perform best when aligned with relevant seasons or life stages.
• Advertiser Campaigns Align with Consumer Behavior:
Brands launch aggressive campaigns during peak shopping seasons and promotional periods, increasing competition and revenue potential.
• Prepare Inventory in Advance:
Schedule and prioritize premium campaigns or high-yield line items ahead of known demand periods to capture maximum value.
• Use GAM Trends to Forecast Spikes:
Google Ad Manager’s historical reports can help identify seasonal patterns, guiding better planning and pricing strategies year over year.
How to Use GAM Reports to Schedule Ads Strategically
Tips on leveraging historical data, dayparting, and custom schedules in Google Ad Manager.
Google Ad Manager (GAM) offers powerful reporting tools that help publishers make data-driven decisions about when and how to serve ads. By analyzing historical performance reports, you can identify patterns in impressions, CTRs, and revenue across different hours, days, and devices. This insight allows you to schedule high-paying line items during peak traffic periods and avoid low-engagement windows.
To fine-tune your strategy, use dayparting—a feature that lets you set ads to run only during selected time blocks, such as morning commutes or evening scroll hours. You can also create custom delivery schedules for premium campaigns, ensuring they appear when users are most likely to engage. By combining historical data with smart scheduling, you can maximize ad visibility, improve fill rates, and boost overall revenue performance.
• Analyze Historical Data:
Use GAM’s historical reports to identify trends in impressions, clicks, CTR, and revenue based on time of day, day of week, and device type.
• Identify Peak Engagement Times:
Look for high-traffic hours and days when users are most active. Focus on scheduling premium campaigns during these periods.
• Leverage Dayparting:
Use the dayparting feature in line items to run ads only during selected time slots—like mornings, evenings, or weekends—based on engagement patterns.
• Create Custom Delivery Schedules:
Set up custom start and end times for specific campaigns to ensure they run during peak windows or seasonal demand periods.
• Target by Device & Geography:
Use reporting insights to schedule ads based on device usage (mobile vs. desktop) or geographic activity, optimizing delivery for your audience.
• Monitor Fill Rates by Time:
Track how fill rates fluctuate throughout the day or week, and schedule ads when inventory is most likely to be filled.
• Adjust Bidding and Priority Settings:
For high-performing periods, increase CPM floors or line item priority to attract higher-quality demand and boost revenue.
• Use Report Filters for Clarity:
Apply filters for ad units, orders, creatives, or geographies to narrow down performance data and make informed scheduling decisions.
• Review Regularly & Iterate:
Continuously review and refine schedules based on updated GAM data to keep your ad strategy aligned with user behavior and advertiser trends.
