When it comes to Google Ads, choosing the right campaign type can make or break your ecommerce strategy. While both Shopping Ads and Performance Max can help you drive sales, the way they function and the results they deliver can vary significantly. 

Whilst one is highly specific and product-focused, the other leverages automation to spread across multiple channels with minimal input. Understanding how these two systems differ is key to crafting an effective advertising approach tailored to your business.

In this article, we’ll dive into the core differences between Shopping Ads and Performance Max, breaking down how each works and when one might be a better fit over the other.

Shopping Ads, also known as Product Listing Ads (PLAs), are a powerful way to showcase your products on Google’s search engine results page (SERP). These ads display product images, prices, and descriptions, giving customers a quick snapshot of your offerings and are designed to drive direct traffic to product pages, allowing users to quickly find and purchase what they’re looking for.

Shopping Ads rely on the data in your Google Merchant Centre account, which contains product information like pricing, availability, and descriptions. Once the product feed is set up and approved, these ads can appear when users search for relevant terms in Google Search or 

. Advertisers only pay when a user clicks on the ad and lands on their website (CPC – Cost per Click).

Performance Max is a more recent campaign type introduced by Google Ads that aims to provide advertisers with a streamlined, all-in-one solution. This campaign type uses machine learning to optimise performance across multiple channels, including Search, Display, YouTube, Gmail, and Discover. Performance Max allows advertisers to reach potential customers across Google’s entire advertising ecosystem, all within a single campaign.

Unlike Shopping Ads, Performance Max doesn’t rely on a single ad format or specific targeting method. Instead, it combines several ad types, such as text, image, and video ads and automatically distributes them across various Google properties based on the user’s behaviour and intent. The system uses Google’s machine learning to optimise ad delivery and bidding in real-time, making it a more automated approach to advertising.

Key differences between shopping ads and Performance Max

While both Shopping Ads and Performance Max aim to drive conversions and boost sales, there are significant differences between the two. Understanding these distinctions will help you choose the right solution for your business goals.

Shopping Ads require a more hands-on approach when it comes to setup. Advertisers must create a product feed in Google Merchant Centre, which includes detailed information about their products. Shopping Ads are generally run with a targeted product focus, meaning you’ll have to create and manage individual campaigns based on product categories or specific items. Performance Max simplifies the campaign management process by automating much of the work. You’ll still need to upload assets (such as images and text), but the system takes care of distributing ads across multiple channels. This is a great option for advertisers looking for ease of use and greater automation.

, meaning your ads will be shown based on specific search queries entered by users. However, you can also set negative keywords to prevent your ads from appearing for irrelevant searches. While Shopping Ads can be highly effective, they don’t offer the same level of cross-channel reach or automation.

Performance Max, on the other hand, is built on machine learning, which automatically optimises ads and bids to target the best-performing audiences. It doesn't require specific keywords and instead targets users based on intent signals from across Google’s network. This can result in higher efficiency, especially for businesses with limited time or resources for manual optimisation.

When it comes to reporting, Shopping Ads offer detailed data about the performance of individual products, campaigns, and ad groups. This allows you to monitor which products are performing best and optimise your campaigns accordingly. 

Performance Max, however, takes a more high-level approach to reporting

. While it provides valuable insights into overall campaign performance, you don’t get as granular of a view as you would with Shopping Ads. The trade-off is that Performance Max’s machine learning optimises the campaign for you, so you don’t need to manually tweak everything.

When should you use shopping ads vs Performance Max?

Shopping ads: ideal for a specific product focus

Shopping Ads are perfect for advertisers who want to focus on promoting individual products or specific product categories. If your business has a clear product inventory with well-defined categories, Shopping Ads allow you to target searchers who are actively looking for those specific items. They’re also ideal if you have a solid understanding of 

 and want to maintain control over your bids and campaigns.

Performance Max: ideal for broader reach and automation

If you want to leverage Google’s entire advertising ecosystem and benefit from automated optimisation, Performance Max is the better choice. It’s especially useful for businesses that want to cast a wide net and target users across different stages of the 

. Additionally, if you’re looking for a more automated approach with minimal manual management, Performance Max can help you achieve optimal results with less effort.
