The search ad market just sent two loud signals in the same week, and most advertisers missed the second one. Alphabet posted Q1 2026 search revenue of $60.4 billion, up 19 percent year over year, while Microsoft confirmed Bing crossed 1 billion monthly active users for the first time. Bing search ad revenue, excluding traffic acquisition costs, grew 12 percent. That number is small in absolute dollars, but the direction tells you something important about where to put incremental search budget for the rest of the year.
If you run paid search for an ecommerce brand, a lead gen funnel, or a local services business, your revenue-tracking setup needs to answer a new question: how much of your category demand is now happening on Bing or inside AI search experiences, and is that share growing faster than your spend allocation reflects? In this post, you will see what the new data shows, why your current bing search ad share is probably underweighted, and the audit steps that move the needle.
What the Q1 2026 Earnings Actually Say
Google Search and Other revenue hit $60.4 billion in Q1 2026, with the pure Search line growing 31 percent year over year. That is the strongest growth rate Alphabet has reported in years. CEO Sundar Pichai told investors that queries are at an all-time high, with strength concentrated in retail, finance, and health.
The number that should make you pay attention is on the other side of the ledger. Google Network revenue, which is the network of third-party sites where Google places ads, dropped to $6.97 billion. That is below $7 billion for the first time, and it has declined every single quarter since Q1 2024. Two years ago Google Network was about 12 percent of Google ad revenue. It is now about 9 percent.
Translation for your media plan: Google itself is shifting more dollars into owned Search and YouTube placements and away from the open network. If your Google Display Network campaigns are quietly underperforming, you are seeing the same thing the financials show.
Why Bing Search Ad Share Just Got Strategic
Microsoft made the bigger announcement of the week, and almost nobody covered it. CEO Satya Nadella told analysts that Bing reached 1 billion monthly active users for the first time, with search ad revenue up 12 percent excluding traffic costs. Edge browser has gained market share for 20 consecutive quarters.
Here is the catch. Bing’s global search share is still about 5 percent according to StatCounter’s March 2026 data. The gap between 1 billion monthly users and 5 percent share tells you most of those users are low-frequency, often arriving through default settings on Edge or Windows. That is not a bad thing. Default-driven traffic is high-intent and underpriced compared to the same query on Google.
For paid search teams, the practical bing search ad share question is simple: are you bidding on Bing for your top 20 commercial keywords, or are you running a single low-budget mirror campaign and calling it covered? Most agencies and in-house teams are doing the second thing. The same gap shows up when you compare Google Ads versus Meta for high-intent leads: most teams default to one platform without testing where their actual buyers are.
The Bing Search Ad Share Audit You Should Run This Week
Pull up your Microsoft Advertising account and your Google Ads account side by side. Run a one-week comparison on your top revenue-driving keyword cluster and check three things.
First, impression share. If your Microsoft Advertising lost-impression-share-budget is above 10 percent on your highest-converting cluster, you are leaving cheap volume on the table. Bing CPCs in most B2B and high-consideration verticals run 30 to 50 percent below Google for the same keyword.
Second, conversion rate. Bing audiences skew older, higher income, and more desktop. For finance, B2B SaaS, healthcare, and professional services, Bing conversion rates frequently match or beat Google. For consumer ecommerce in younger demographics, Google still wins. Look at your own data, not the industry average. If you do not yet have a clean view of which marketing metrics actually predict revenue, that is a higher-priority fix than any platform reweight.
Third, attribution coverage. If you are not feeding offline conversions into both platforms, your conversion data is incomplete. Microsoft’s Universal Event Tracking and offline conversion imports work the same way Google’s do, and they make the same kind of difference to your bidding signals.
What the Google Network Decline Means for Display Strategy
That $6.97 billion Google Network number is a signal you cannot ignore if you are running any kind of display or programmatic. Two consecutive years of decline, while Google Search grows 31 percent in a single quarter, means Google is consolidating dollars into its owned-and-operated surfaces.
For your display budget, the read is straightforward. Open-network Display Network campaigns are getting less of Google’s optimization attention than YouTube placements, Performance Max, and Demand Gen. If your PPC playbook still treats Display as an awareness layer that runs on autopilot, you are funding a shrinking part of the ecosystem.
The fix is not to abandon Display. It is to rebalance. Move your awareness budget into YouTube and Demand Gen for the upper funnel, keep a small Display retargeting layer with strict placement exclusions, and put the dollars you free up into testing Bing search at higher impression-share targets.
How AI Search Changes the Click Math
Pichai also said queries are at an all-time high, even as third-party studies show AI Overviews are reducing organic clicks. Ahrefs found that AI Overviews correlate with a 58 percent lower click-through rate on a 300,000-keyword study. Chartbeat data shared with Axios showed small publishers lost 60 percent of search traffic over two years.
For paid search, the implication is the opposite of what most people assume. When organic clicks shrink, the value of a paid click rises because the paid ad is now one of the only links above the AI summary. CPCs on commercial intent queries are likely to keep climbing through 2026, especially in retail, finance, and health where Pichai called out specific strength.
Your defensive move is to lock in conversion-rate gains now. Cleaner landing pages, faster site speed, and tighter Google Ads account hygiene all compound when CPCs climb. A 10 percent conversion-rate lift on a 20 percent more expensive click leaves you ahead.
How to Reweight Your Search Spend for the Rest of 2026
If you run a $50,000 monthly search budget today and 95 percent of it is on Google, you are statistically representative of the market. You are also statistically leaving money on the table. Use the new earnings data to set a quarterly rebalancing rule.
Start with a 90/10 Google to Bing split as your baseline test. Run it for 30 days on your top three campaigns by revenue. If Bing CPA comes in within 20 percent of Google’s CPA, increase to 85/15 for the next 30 days. Keep going until Bing’s incremental CPA crosses your tolerance, then hold the split there for the rest of the quarter.
The same logic applies to Google Performance Max versus Google Network Display. PMax now gets the optimization attention. If you have legacy Display campaigns running independently, fold them into PMax as audience signals or shut them down. The earnings data is telling you Google does not see open Display as the future.
What This Means for Your Reporting and Forecasting
One last update for your reporting cadence. If you are still aggregating paid ad metrics as a single search-channel line in your dashboard, split it into three lines for the rest of 2026: Google Search, Bing Search, and Google Display Network. The trends are diverging fast enough that a blended number will hide both your wins and your losses.
For forecasting, assume Google Search CPCs continue to climb 8 to 15 percent year over year on commercial intent queries, Bing CPCs hold flat or rise 3 to 5 percent, and Google Network volume continues to decline. Build those assumptions into your 2026 plan and your finance team will not be surprised when actual costs land where the data says they will.
What to Do Next on Your Bing Search Ad Share
The 1 billion Bing user milestone, the 31 percent Google Search growth, and the 9 percent Google Network share all point to the same conclusion. The search ad market is consolidating into two clear winners, Google Search and Bing, while the open display network keeps shrinking. Your bing search ad share decision for 2026 is not whether to be on Bing. It is how much.
