Shopping campaigns require more ongoing management for several reasons. Most eCommerce stores are frequently updating their inventory, competitive products arrive at slightly lower prices, and as a feed changes automated bidding may require recalibration.
The Shopping platforms are constantly monitoring eCommerce campaigns that utilize their ad platform. Typically this is done by bots and it frequently results in Merchant Center exceptions, warnings, and errors arriving in the form of unwelcome emails. We monitor Shopping campaigns for these issues and handle them as they arrive.
Reporting and performance management is a crucial need for eCommerce advertisers. Most of our eCommerce clients receive reports monthly, detailing performance in the period vs previous periods, and highlighting work on ongoing challenges and issues.
SKU-Level Performance Tracking
SKU-level tracking isn’t just for Performance Max – it’s one of the most valuable tools in managing standard Shopping campaigns. Every product in the feed is effectively running its own mini-campaign, and overall ROAS figures can mask significant variation underneath. A catalog that looks acceptable at the campaign level often contains a mix of strong performers, marginal products consuming budget at a loss, and items that aren’t serving at all.
We track performance at the individual product level to identify which SKUs are generating profitable revenue, which are generating clicks without converting, and which have impression share problems due to feed issues or bids that are too low to compete. The impact of SKU-level optimization on campaign efficiency is significant – pulling budget from underperforming products and concentrating it on proven performers is one of the most direct paths to improving Shopping ROAS. Acting on this data may mean adjusting bids at the product level, restructuring campaigns around product tiers, or excluding poor performers entirely.
Search Term Monitoring and Negative Keywords
Unlike search campaigns, Shopping campaigns don’t use keywords directly – Google matches products to queries based on the feed. That makes search term monitoring especially important. Without regular review, irrelevant queries accumulate unchecked and erode ROAS over time. Negative keyword discovery for Shopping campaigns is an ongoing process, not a one-time setup task. We review search term reports regularly to catch irrelevant traffic before it becomes a meaningful drain on budget.
Search term data also informs feed improvements. If high-intent queries are triggering the wrong products, or strong queries aren’t triggering anything at all, that’s often a signal that product titles, descriptions, or category mapping in the feed need adjustment.
Feed Management and Optimization
The product feed is the foundation of a Shopping campaign, and it requires ongoing attention. Feed quality directly affects how many products are eligible to serve, how accurately Google matches them to relevant queries, and what bids are competitive for a given product. Disapprovals, missing attributes, pricing mismatches, and stale product data all reduce coverage and can suppress performance without any obvious signal in campaign metrics.
Product feed optimization is part of ongoing Shopping campaign management – not just a launch task. As inventory changes, new products are added, and seasonal assortments shift, the feed needs to stay current and clean to maintain coverage and data quality.
Bid Strategy and Impression Share Management
Automated bidding in Shopping campaigns requires periodic oversight, particularly as the product mix and conversion data evolve. Bid strategies trained on one period’s data may need recalibration when seasonal patterns shift, when new products are introduced, or when competitive dynamics change. Impression share metrics tell us whether the campaign is capturing its available market or losing ground – and critically, whether those losses are due to budget constraints or competitive rank. Each cause calls for a different response.
