Introduction

Customers do not stay in one place online. In a single day, someone might search on Google, watch a YouTube Short, check directions on Google Maps, scroll the Discover feed on their phone, read emails in Gmail and browse websites that show display ads. Reaching them consistently once meant running separate campaigns for each channel, each with its own settings, budgets and creative.

Performance Max changes this. It is a single Google Ads campaign that can show ads across all of Google’s main channels, using machine learning to decide where, when and to whom to show them, based on the goals you set. Since its launch, it has become one of the most widely used campaign types, especially for online stores, and Google has continued to add features and reporting.

Performance Max can be powerful, but it is also widely misunderstood. Some businesses see excellent results; others find it spends budget on low-value placements or claims credit for sales that would have happened anyway. The difference usually comes down to setup: tracking, goals, creative, audience signals, product feeds and ongoing review.

This article explains how Performance Max works, its benefits and limitations, how to set it up well and how to measure it fairly. It reflects how our digital marketing team at Dsigngo Group uses Performance Max for clients in Sri Lanka and the UAE.

What is Performance Max?

Performance Max is a goal-based campaign type in Google Ads. Instead of choosing keywords and placements for each channel, you provide:

• A conversion goal, such as online sales, leads or store visits.
• A budget and bidding strategy, such as Maximise conversion value with a target ROAS.
• Creative assets: headlines, descriptions, images, logos and videos.
• A product feed from Google Merchant Center, for online stores.
• Audience signals, such as customer lists and interests, which guide Google’s targeting.
• Locations, languages and other settings.

Google then uses this information to show ads across:

• Search, including text ads and Shopping ads.
• YouTube, including in-stream, in-feed and Shorts.
• Display, on millions of websites and apps.
• Discover, on the Google app and mobile home screens.
• Gmail, in the promotions and social tabs.
• Maps, for businesses with locations.

Ads are assembled automatically from your assets to suit each channel and placement.

The benefits of Performance Max

Reach across every Google channel

One campaign can reach customers at different stages: discovering your brand on YouTube, comparing products on Shopping, and searching for you by name. This helps businesses that lack the time or budget to manage many separate campaigns.

Machine learning for bidding and targeting

Performance Max uses Smart Bidding and Google’s audience understanding to find people likely to convert, often including audiences that manual targeting would not have tried. Blog Article 2 explains Smart Bidding in detail.

Strong results for online stores

For eCommerce businesses with a good product feed and conversion tracking, Performance Max can drive sales efficiently across Shopping, Search and other placements. It has largely replaced older Smart Shopping campaigns.

Support for local business goals

Businesses with physical locations can use Performance Max with store goals to drive visits, calls and direction requests, using Maps and local placements.

Simpler management

Instead of managing many separate campaigns, advertisers manage fewer campaigns with asset groups. This frees time for strategy, creative and landing pages.

Better visibility than before

Early versions of Performance Max offered limited reporting. In 2025, Google introduced channel performance reporting, showing results by channel, along with full search terms reporting and more detailed asset performance data. This makes it easier to understand where budget goes and which creative works.

The limitations to understand

Less direct control

You cannot choose exact keywords for every search or select every placement. Google decides where ads appear based on its predictions. Some controls exist, such as brand exclusions, negative keyword lists in some circumstances, account-level placement exclusions and URL rules, but control is less detailed than in Search campaigns.

Dependence on conversion data

Performance Max optimises for the conversions you track. Poor or inflated tracking leads to poor decisions. It needs meaningful conversion actions and, ideally, values.

Risk of claiming brand and existing demand

Performance Max can show ads for searches of your own brand name and to people who were already likely to buy. This can make results look better than the true extra value created. Brand exclusions, separate brand Search campaigns and careful measurement help.

Creative quality matters a lot

Because ads appear across very different channels, weak or missing assets reduce performance. If you do not supply videos, Google may generate simple ones automatically, which often look generic.

Learning time and budget

Performance Max needs time and sufficient budget to learn. Very small budgets may not generate enough data for good optimisation.

Setting up Performance Max well

1. Get tracking right first

Track meaningful conversions, assign values where possible and test everything before launch. For online stores, track purchase values accurately. For lead generation, consider importing qualified leads or sales as offline conversions, so the campaign learns from real outcomes. Insights Article 3 explains conversion tracking.

2. Choose the right goal and bidding strategy

For online stores, Maximise conversion value with a target ROAS is common once data is stable. For lead generation, Maximise conversions with a target CPA is often suitable. Set targets based on profitability, as explained in Insights Article 5.

3. Organise asset groups by theme

An asset group is a set of creative assets and audience signals for a particular theme, such as a product category, service line or customer segment. Separate asset groups allow messages and images to match each theme. For example, a furniture store might have asset groups for office furniture, bedroom furniture and outdoor furniture.

4. Provide strong, varied assets

Supply the full range of assets:

• Several headlines and long headlines, written for different angles: benefits, offers, trust and calls to action.
• Descriptions that explain what makes you different.
• High-quality images in landscape, square and portrait formats.
• Logos in square and landscape formats.
• Videos in horizontal, square and vertical formats, ideally including short vertical videos for YouTube Shorts.

Our design and video teams create assets specifically for Performance Max placements.

5. Optimise your product feed

For online stores, the Merchant Center feed is critical. Use descriptive product titles, accurate prices and availability, high-quality images, correct categories and clear shipping information. Custom labels can group products by margin, best-seller status or season, allowing different campaigns or asset groups to prioritise them.

6. Add audience signals

Audience signals tell Google where to start looking. Good signals include your customer lists (uploaded with consent), website visitors, people who searched for relevant terms, and interest or demographic segments. Signals guide learning; they do not restrict targeting.

7. Set brand and URL controls

Use brand exclusions if you want Performance Max to avoid brand searches that a separate Search campaign already covers. Use URL settings to control which landing pages can be used, so traffic goes only to relevant pages.

8. Run Search alongside Performance Max

Search campaigns with exact or phrase match keywords generally take priority when a search exactly matches a keyword in them. Running Search for core, high-intent keywords and your brand, alongside Performance Max for wider reach, gives a balance of control and scale.

Measuring Performance Max fairly

To judge Performance Max properly:

• Review channel reports to see results and costs by Search, YouTube, Display, Discover, Gmail and Maps.
• Check search term insights for the share of results coming from brand searches.
• Review asset reports to replace low-performing images, videos and text.
• Compare total business results, such as total online sales and new customers, before and after launch, not just Google Ads conversions.
• Watch new versus returning customers. Performance Max can use a new customer acquisition goal to value new customers more highly.
• Use experiments where possible, comparing Performance Max with your existing setup.

Performance Max for lead generation

Performance Max is best known for eCommerce, but it can also generate leads. The risk is low-quality leads, for example spam form submissions from Display placements. To reduce this:

• Optimise for qualified leads or sales imported from your CRM, not raw form fills.
• Use forms with validation and simple qualifying questions.
• Exclude poor-quality placements where possible.
• Monitor lead quality closely with the sales team.

Who benefits most from Performance Max?

Performance Max suits some businesses better than others. It usually works well for:

• Online stores with a product feed, accurate purchase tracking and enough monthly sales to learn from.
• Retailers with physical branches that want to drive store visits as well as online sales.
• Hotels, tour operators and travel businesses with strong visual content and clear booking tracking.
• Businesses with good creative, especially video, that can make use of YouTube and Discover placements.
• Established advertisers that already run successful Search campaigns and want to expand reach.

It may be less suitable, at least at first, for:

• Businesses with no conversion tracking or very few conversions each month.
• Highly specialised B2B services where most valuable customers search with specific terms, which Search campaigns can target more precisely.
• Businesses with very small budgets that need tight control over every click.
• Brands without suitable images or videos.

For these businesses, we usually start with Search campaigns, build tracking and creative, then test Performance Max when the foundations are in place.

Creative best practices for each channel

Because Performance Max assembles ads for many placements, creative should be designed with each channel in mind:

Refreshing creative every few months, especially before seasonal campaigns, prevents audiences from tiring of the same ads.

Common Performance Max mistakes

• Launching without reliable conversion tracking.
• Using one asset group for every product or service, which forces generic messages.
• Uploading only a few low-quality images and no video.
• Leaving the product feed with poor titles, missing images or wrong prices.
• Letting Performance Max take over brand searches without measuring the true benefit.
• Judging results after a few days, during the learning period.
• Ignoring channel, search term and asset reports now that they are available.
• Optimising for form fills that never become customers.

Our Performance Max management routine

Each month, our team reviews channel performance and costs, search term insights and brand share, asset performance ratings and creative fatigue, product group results by margin and stock levels, audience signal performance, and conversion quality. We then refresh assets, adjust targets, update the feed and recommend landing page improvements. These reviews are summarised in plain language in our monthly report, so clients understand not only what Performance Max achieved, but why.

Performance Max compared with other campaign types

Using Performance Max with a small budget

Small businesses can use Performance Max, but they need to be selective. Focus on the most profitable products or one key service, rather than spreading a small budget across everything. Use a single, well-built asset group with excellent images and at least one short video. Make sure conversion tracking captures the main action, and allow enough time to learn before making changes. If results remain unstable after several weeks, it may be better to concentrate the budget on Search campaigns until conversion volume grows, then return to Performance Max later.

Planning seasonal Performance Max campaigns

Festive seasons are important for many businesses in Sri Lanka and the UAE. Prepare seasonal asset groups or campaigns in advance, with festive images, videos and offers, and use seasonality adjustments when a short promotion is expected to change conversion rates sharply. Update product feeds with promotional prices and stock, and return assets to normal promptly when the season ends, so outdated offers do not continue to appear.

Illustrative example

The following example is illustrative and does not describe a real client.

A Sri Lankan online store sells cosmetics and personal care products, with several hundred items. It runs a basic Shopping campaign and a few Search campaigns, but has no videos and limited conversion values.

The team improves the product feed with clearer titles and better images, sets up accurate purchase values and creates custom labels for high-margin and best-selling products. A Performance Max campaign is built with asset groups for skincare, hair care and gift sets, each with tailored headlines, lifestyle images and short vertical videos produced by the video team. Customer lists are added as audience signals, and brand searches are covered by a separate Search campaign. Monthly channel and asset reviews show that video placements bring many first-time buyers, so new seasonal videos are added before festive periods.

Frequently asked questions

Should Performance Max replace all other campaigns?

Usually not. Many businesses get the best results by running Performance Max alongside Search campaigns for brand and core keywords.

How much budget does Performance Max need?

It needs enough budget to generate regular conversions so it can learn. We recommend budgets based on your goals, product prices and expected conversion rates.

Can we see where our ads appear?

Channel performance reports now show results by channel, and placement information is available for some inventory. Visibility has improved significantly since 2025.

Do we need videos?

Videos are strongly recommended. Without them, Google may create basic videos automatically. Short, well-made videos usually improve performance on YouTube placements.

How long before Performance Max shows results?

Allow several weeks for learning, depending on budget and conversion volume, before judging results.

Conclusion

Performance Max offers modern businesses a way to reach customers across every Google channel from one campaign, guided by machine learning and their own goals. Its benefits are greatest when tracking is accurate, creative is strong, product feeds are well maintained, audience signals are thoughtful and results are reviewed honestly. Its limitations, less direct control and the risk of claiming existing demand, can be managed with brand controls, Search campaigns alongside it and careful measurement.

Our team builds and manages Performance Max campaigns with creative from our own design and video studios, so every asset is made for the channels it appears on.
