An enterprise layer, not a magic bidder
Search Ads 360 (SA360) is Google’s enterprise layer on top of Google Ads, Microsoft Advertising, Yahoo! Japan and Baidu. It adds cross-engine management, Floodlight measurement, auction-time bidding on custom signals and central budget management. Pricing is negotiated individually based on the volume of managed spend. It pays off for multi-engine, multi-market setups with substantial search budgets. For smaller, Google-only accounts it is an unnecessary fee.

Almost nobody writes about SA360 independently. The available content comes from Google and a handful of vendors selling the platform. As a certified SA360 agency, we both deploy it and talk clients out of it. This article is the decision framework we use internally.

What is Search Ads 360 and how does it differ from Google Ads?
Search Ads 360 is Google's platform for managing search campaigns across multiple ad systems from one interface: Google Ads, Microsoft Advertising, Yahoo! Japan and Baidu (Google, 2026). It is not a replacement for Google Ads but a layer above it. Campaigns keep running in the native systems; SA360 manages, measures and bids on them.
SA360 is part of the Google Marketing Platform, so it connects natively to Campaign Manager 360 and Floodlight measurement. The rebuilt version launched in 2022 runs on the same technology stack as Google Ads, which means new engine features arrive faster than in the legacy interface (Google Marketing Platform blog, 2022).
Just as important is what SA360 is not: it is not a magic bidder that beats Smart Bidding. On a single engine with conversions measured in Google Ads, auction-time bidding does practically the same thing. The value appears only when you manage multiple engines, multiple accounts and multiple conversion data sources at once.
What does SA360 actually add over Google Ads?
Four things you do not get in Google Ads alone: cross-engine management and reporting, Floodlight conversions shared with CM360, auction-time bidding on custom signals including for Microsoft Advertising, and central budget management via the Performance Center. The rest are conveniences for large teams: templates, bulk edits, automated rules across accounts.
| Feature | Google Ads | SA360 |
|---|---|---|
| Managing Google campaigns | yes | yes (unchanged) |
| Microsoft Advertising, Yahoo! Japan, Baidu | no, separate in each system | yes, one interface |
| Auction-time bidding for Google | yes (Smart Bidding) | yes |
| Auction-time bidding for Microsoft | native in Microsoft Ads only | yes, steered from SA360 since 02/2025 |
| Floodlight conversions + CM360 deduplication | no | yes |
| Custom conversion signals (business data, custom variables) | limited (imports, value rules) | yes, directly in bidding |
| Cross-engine portfolio bid strategies | no | yes |
| Budget management across engines | manual | Performance Center with forecasting |
| Price | free | percentage of spend |
Two features deserve detail. Floodlight: one measurement system across search, display and video means deduplicated conversions across channels, so bidding stops overpaying search for conversions another channel already bought. Auction-time bidding for Microsoft: since February 2025, SA360 steers Microsoft Advertising bids in real time at the auction (Search Ads 360 Help, 2025). For advertisers who take Microsoft Ads in Europe seriously, this is the strongest argument for the platform.
What this looks like in practice: for travel-tech platform Daytrip, deploying SA360 with Floodlight-based bidding delivered a 17 % higher conversion value and a 15 % higher ROAS across Brand and Non-Brand campaigns. The full setup is in the Daytrip case study.
How much does SA360 cost?
Google does not publish a price list. The fee is negotiated individually as a percentage of managed search spend, and the rate depends on spend volume and commitment length. Access goes through Google or certified partners; there is no self-service signup. The key question is not "what does it cost" but "what does the platform have to improve to pay for itself": that is realistic when you consolidate fragmented multi-engine management, not on a well-run, Google-only account. Want concrete terms for your account? Get in touch and we will help you negotiate them.
From what spend level does SA360 make sense?
Our threshold: roughly 50,000 EUR in monthly search spend, and only when other conditions hold as well, typically a second engine or multiple markets and accounts. Below that level, the fee and the administration reliably outweigh the benefits.
Consider SA360 when at least two of these apply:
- You spend over 50,000 EUR per month on search and the volume is growing.
- You invest meaningfully in Microsoft Advertising alongside Google Ads.
- You manage multiple accounts, brands or markets and stitch reporting together by hand.
- You run CM360 and want deduplicated Floodlight conversions feeding your bidding.
- You bid on values Google Ads cannot see: margin, LTV, offline closes, lead scores.
- Budget pacing across engines and markets currently lives in spreadsheets.
A concrete European example: a retailer running Google Ads in eight markets plus Microsoft Advertising in DACH and the Netherlands, with margin data in a warehouse, is a textbook SA360 case. A single-market store spending 15,000 EUR per month on Google alone is not.

When is SA360 not worth it?
It is not worth it for Google-only advertisers with a single account, for accounts below roughly 50,000 EUR in monthly search spend, and for teams without capacity to own the measurement setup. In those situations you pay a percentage of spend for features you will not use, or that Google Ads provides for free.
Situations where we talk clients out of SA360:
- One engine, one account. Smart Bidding in Google Ads does auction-time bidding for free. SA360 adds nothing but an invoice.
- Search spend below the threshold. The fee on a small spend is small, but the fixed costs of setup, migration and platform administration are not.
- Conversions measured only in GA4 or Google Ads, with no further plans. Without Floodlight or custom signals, the bidding layer loses its point.
- The account's real problem is elsewhere. A weak feed, a missing Performance Max structure or broken tracking will not be fixed by SA360. The platform scales good work, not bad work.
- Nobody will own it. SA360 needs an admin who understands bid strategies and Floodlight. Without ownership it degrades into an expensive reporting tool.
An honest note: most e-commerce accounts we audit would not benefit from SA360. The typical performance ceiling is measurement, feed quality and structure, not a missing enterprise layer. That is also why only around 3 % of our clients actually run SA360 today.
What does an SA360 migration look like?
Migration is primarily a measurement project, not a campaign project. Campaigns do not move; they stay in the native systems. What decides success is wiring conversions correctly, converting bid strategies to portfolios, and a transition period in which you resist drawing conclusions from strategies that are still learning.
The checklist we use:
- Map the conversion stack: what Google Ads measures, what GA4 measures, what CM360 measures, where duplicates arise.
- Decide the primary conversion source for bidding (Floodlight vs native conversions) and document the counting differences.
- Link the engine accounts (Google Ads, Microsoft Advertising) and verify data completeness.
- Convert bid strategies to SA360 portfolios gradually, campaign group by campaign group, never all at once.
- For the first 4 to 6 weeks, compare performance against the pre-migration period and let strategies relearn.
- Set up budget management and reporting only after bidding stabilizes.
- Train the team: who owns the platform, who owns bid strategies, who owns measurement.
As a certified SA360 agency, we arrange platform access and migration, including negotiating the terms.

FAQ
What does SA360 stand for?
SA360 stands for Search Ads 360, Google's enterprise platform for search campaign management. It is part of the Google Marketing Platform alongside Campaign Manager 360 and Display & Video 360. From one interface it manages campaigns in Google Ads, Microsoft Advertising, Yahoo! Japan and Baidu.
How much does Search Ads 360 cost?
There is no public price list. The fee is negotiated individually as a percentage of managed spend and depends on spend volume and commitment length. Add internal costs on top: setup, measurement migration and ongoing platform administration. Contact us for concrete terms.
Does SA360 replace Google Ads?
No. Campaigns keep running in Google Ads and the other native systems. SA360 is a control layer above them that unifies measurement, bidding and reporting. You will still log into Google Ads for features SA360 does not cover, including parts of Performance Max configuration.
Is SA360 bidding better than Smart Bidding in Google Ads?
On a single Google account with native conversions, no; it is the same auction-time technology. The difference appears with Floodlight conversions, custom signals (margin, LTV, offline data) and cross-engine portfolios. Since February 2025, SA360 also steers auction-time bidding for Microsoft Advertising (Search Ads 360 Help, 2025).
At what budget does SA360 pay off?
Our rule of thumb: from around 50,000 EUR in monthly search spend, provided you also run multiple engines, markets or advanced measurement. Below the threshold, invest in measurement and campaign structure instead of a platform.
Can SA360 manage Performance Max and Shopping campaigns?
Yes. SA360 supports Google Ads Performance Max and Shopping campaigns and syncs them into unified reporting and budget management. Some configuration still happens in the native Google Ads interface. Microsoft Advertising follows the same principle with a narrower feature set.
Do I need Campaign Manager 360 to use SA360?
Not strictly; SA360 works on its own. The biggest measurement benefit, however, comes with CM360: Floodlight tags measure conversions consistently across search, display and video and deduplicate them. Without CM360 you mainly use cross-engine management and bidding, not unified measurement.
How long does an SA360 migration take?
Plan for 6 to 10 weeks from decision to stable operation. Linking accounts takes days; most of the time goes into the measurement audit, converting bid strategies to portfolios and the learning period while strategies gather data. Migrate gradually, never the whole account at once.
Conclusion
SA360 is a strong tool for a narrow group of advertisers: large search spend, multiple engines or markets, advanced measurement and a team that can run the platform. For everyone else it is an extra fee with no matching benefit. The decision should rest on numbers, not on the feeling that an enterprise stack is something you ought to have.
