Understanding Standard Shopping campaigns: A targeted approach

Standard Shopping campaigns focus solely on product listings, appearing in the Google Shopping tab and alongside search results. They offer more granular control over targeting, bidding, and campaign structure.

The primary control mechanism for these campaigns is the use of product feeds and keyword targeting. Advertisers manually manage bids, budgets, and targeting settings, providing a level of granular control over where and how ads are displayed.

Pros:

1. Granular control: Advertisers can set specific bids for individual products or product groups, offering precise control over ad spend.
2. Predictable performance: The ability to manage and monitor performance on a product-by-product basis can lead to more predictable and measurable outcomes.
3. Data transparency: Detailed reporting allows advertisers to analyse performance metrics at a granular level, such as clicks, conversions, and cost-per-acquisition (CPA).
4. Portfolio bid strategies: Use portfolio-level bidding to manage multiple campaigns efficiently.
5. Priority settings: Prioritise products within campaigns for better performance.
6. Search Term Analysis: Gain in-depth insights into search terms driving clicks and conversions.
7. Brand safety: Ensure ads appear alongside relevant and reputable content.

Cons:

1. Manual management: Requires significant time and effort to set up and optimise campaigns, including adjusting bids and targeting.
2. Limited reach: Ads are limited to Google Search and Shopping Network, potentially missing out on other valuable traffic sources.
3. Steeper learning curve: Understanding advanced features like portfolio bid strategies and priority settings can be challenging.

The rise of Google Performance Max (PMax): A comprehensive approach

Google’s most recent ad format offers a broad-reach approach to advertising across multiple Google networks. By leveraging machine learning and automation, these campaigns optimise your ads for maximum performance across Search, Display, YouTube, Discover, and Gmail. Google Performance Max (PMax) campaigns represent a shift towards automation and machine learning.

Pros:

1. Automation and efficiency: PMax campaigns automate bid management, targeting and ad placement.
2. Expanded reach: Ads are displayed across all of Google’s properties, potentially reaching a wider audience and increasing overall visibility.
3. Advanced machine learning: Google’s algorithms use historical data and real-time signals to optimise campaign performance, potentially leading to better results with less manual intervention.
4. Single campaign: Multiple ad formats (Search, Display, YouTube, etc.) can all be managed within a single campaign.
5. Asset-based approach: Create ad groups using various assets (images, text, videos) for dynamic ad creation.

Cons:

1. Less granular control: Advertisers have less control over specific aspects of the campaign, such as bidding strategies and ad placements compared to Standard Shopping campaigns.
2. Data transparency: Reporting and data granularity are more limited compared to Standard Shopping Campaigns, making it harder to pinpoint which elements are driving performance. There is also greater potential for Ad Creep: If not managed carefully, Performance Max can allocate budget to less relevant ad placements.
3. Learning curve: The reliance on machine learning may require an adjustment period to fully understand and trust the automated processes.

Choosing the right campaign type

To determine whether Google PMax or Standard Shopping Campaigns are better suited for your eCommerce growth, it’s essential to consider several factors, including your business goals, resources, and target audience.

1. Performance and efficiency: Data from early adopters of PMax campaigns indicate that they can drive higher conversion rates and lower CPA due to the advanced optimisation algorithms. However, this advantage often comes with a trade-off in control and transparency. For businesses with limited resources and a need for efficiency, PMax can provide substantial benefits through automation.
2. Control and customisation: If your business requires precise control over every aspect of your ad campaigns, including detailed reporting and bid adjustments, Standard Shopping Campaigns may be preferable. The ability to fine-tune bids and target specific product groups can be invaluable for managing complex inventories and optimising for niche markets.
3. Audience reach: PMax campaigns offer the advantage of a broader reach across Google’s entire ecosystem. For businesses looking to expand their visibility and tap into new audience segments, PMax can provide a significant edge by leveraging Google’s extensive network.
4. Resource allocation: Standard Shopping Campaigns require ongoing management and optimisation, which can be resource-intensive. If your team has the bandwidth to manage these campaigns effectively, the granular control can be beneficial. Conversely, PMax’s automation can be advantageous for businesses looking to streamline their advertising efforts and focus on strategic initiatives.
5. Brand safety: If brand safety is a top priority, Standard Shopping offers more control over where your ads appear.

In some cases, a hybrid approach might be effective. You can use Performance Max for broader reach and automation while employing Standard Shopping for specific product categories or targeting needs. This can help you leverage the strengths of both campaign types.

We recently worked with a client whose online goals were both sales and brand exposure. They relied heavily on distribution networks and wholesale sales so reach and impressions were important to consider in their online strategy.

They had previously only used Standard Shopping and Search Campaigns. Although these campaigns were yielding decent conversions, we enhanced their strategy by introducing a PMax campaign to the mix. In doing this we were able to maximise the reach potential of PMax whilst containing the granular control of standard shopping campaigns.

In the month following the launch we saw a 27% increase in ad impressions and within 3 months we saw a 35% increase in the ROAS.

So which one should you use?

Both Google Performance Max and Standard Shopping campaigns offer valuable features for eCommerce growth, but their effectiveness largely depends on your specific needs and resources.

maxemus Digital Marketing is one of only a few agencies that still commit a good portion of our ad spend to Standard Shopping campaigns. We don’t do this because we’re old school (if that were the case, we’d still be using manual bidding!). We do it because Standard Shopping campaigns still work in the right scenarios. Just like we opt for PMax campaigns when it’s the right choice.

PMax excels in automation and broad reach, making it ideal for businesses seeking efficiency and expanded visibility. On the other hand, Standard Shopping campaigns provide granular control and transparency, catering to those who require detailed management and optimisation.

Ultimately, the best approach involves testing both types of campaigns to see which aligns better with your business goals and delivers the best results. By leveraging data-driven insights and continually optimising your strategies, you can harness the power of Google Ads to drive meaningful growth for your eCommerce business.

Not sure what’s best for your business and need guidance in getting started? Google Ads can be confusing, and with the introduction of AI-powered campaigns that rely heavily on signals from Google Analytics 4 you can waste a lot of time and money trying to figure it out alone.
