Discover the optimised articles performance report

Understand our newly added metrics for clearer Sponsored products campaign insights.

Updated October 9, 2025


Up until now the articles performance report in the Campaigns breakdown on zDirect captured the broader impact of your Sponsored Product ads by tracking all sales that occur after an ad click, even if the purchased item wasn’t the one directly advertised.

Moving forward, the report will focus exclusively on sales of the directly advertised articles. The updated articles performance report gives you clean, accurate data to efficiently optimise your campaigns and calculate profitability. This enhances article-level reporting for all Conversion (Sponsored Products) campaigns in Ad Manager.

What’s new? 

The updated report introduces several improvements to help you analyse your campaign performance more effectively. 

  • Advertised-only articles: to give you clearer data, the report now only shows articles you're actively advertising with Sponsored Product ads. We've removed articles that were bought after an ad click but weren't advertised. This ensures you're analysing data only for your sponsored products.

  • New optimisation metrics: to provide more actionable insights to optimise your campaigns we've added Direct Sales vs. Total Sales to the metrics.

Although the new report lists only your advertised articles, any sales they help generate for other products are still included in your Total Sales metric. This provides a complete view of your ad’s overall impact.

Understand your performance metrics

The new report breaks down performance using several key metrics or key performance indicators, in short KPIs. First, let's define the core terms.

Core advertising KPIs

Core advertising KPIs

Description 

Budget spent

Your total campaign budget, including discounts, vouchers and free media.

Partner invest

The amount you invest in your campaign, excluding discounts, vouchers, and free media.

Viewable impressions

The number of times a user has been exposed to at least 50% of the ads’ content.

Clicks

The number of times a user clicked on your ad.

Cost per click (CPC)

The amount you pay for each click on your ads.

Direct sales KPIs

A direct sale is the primary measure of an ad's effectiveness. When a customer clicks on an ad of a specific article and purchases that exact same article in the advertised model and colour.

Direct sales KPIs

Description 

Direct items sold 

The number of items sold (before cancellations and returns) after a customer clicked on an ad, where the sold article was the same as the one advertised.

Direct conversion rate

The percentage of ad clicks that resulted in a purchase of the exact same article that was advertised.

Direct cost per sold item (CPSI)

The advertising cost for each item sold, calculated only on sales where the sold article was the same as the one advertised. It's calculated as Budget spent / Direct items sold.

Direct gross merchandise value (GMV) 

The revenue generated (before cancellations and returns) from attributed items sold where the purchased article was the same as the one advertised.

Direct return on ad spent (Direct ROAS)

The revenue your business earns for each dollar spent on advertising. It's calculated as direct GMV / budget spent.

Total sales KPIs

Understand the broader influence ads have on your brand. They include all sales from your brand that occurred after a click on this article's ad, including sales of other advertised items or non-advertised items, referred to as halo reporting.

Total sales KPIs

Description 

Items sold

The number of items sold (before cancellations and returns) after a customer clicked on an ad.

Conversion rate

The advertising cost for each item sold. It's calculated as Budget Spent / Items Sold.

Cost per sold item (CPSI)

The percentage of ad clicks that resulted in a purchase.

Gross merchandise value (GMV)

The revenue generated (before cancellations and returns) from all attributed items sold.

Return on ad spent (ROAS)

The revenue your business earns for each dollar spent on advertising. It's calculated as GMV / budget spent.

Definition

The total sales include cross-sells between your advertised products, such as sales of other colours, as well as sales for non advertised products.

The total sales KPIs in the By articles report of the Campaigns breakdown reflect the same overall performance numbers you see at the main campaign level.

Evaluate insights to discover opportunities

You have two distinct views of your performance in direct sales and total sales. Think of them as separate tools for two different tasks and decision to make about: 

Budget and profitability

Use direct metrics to make quick decisions to optimise your performance, this data tells you how effective an ad is at selling the specific article shown.

Long-term brand growth

Use total metrics to gather insights, this data reveals the broader impact your ads have on your brand's overall growth and sales.

Opportunity

Identify your opportunities

Recommended action

Eliminate inefficient spend

Articles with clicks but direct ROAS below your profitability threshold.

Pause or remove these articles from the campaign to stop spending on unprofitable products.

Maximise best performing articles

Articles with a very high direct ROAS.

Move these top performers into a dedicated campaign to better control and scale their budget.

Leverage gateway articles

Articles with a mediocre direct ROAS but a very high total ROAS.

Move these articles to a separate campaign so they can be measured by total ROAS without distorting the main campaign's direct ROAS average.

Check for stock issues

Articles with a high click-through rate (CTR) but unexpectedly low direct sales.

Remove the article from the campaign and check the product's stock availability and product detail page (PDP).

Frequently asked questions

What exactly are halo sales or spillover sales? 

Halo or spillover sale refers to any sale that occurs after an ad was clicked, but the sold article is not the exact article¹ that was clicked. These sales fall into two categories.

Other advertised article

A customer clicks on your ad for an advertised product but buys another advertised product from your campaign instead.

For example: A customer clicks on black jeans you are advertising, but ultimately decides to buy a pair of blue jeans promoted in the same campaign.

Non-advertised article

A customer clicks on your ad, but ends up buying a product from your assortment that was not part of your campaign.

These are positive signals that your ads are driving valuable customer exploration.

Why does my report show other advertised articles as halo sales?

An advertised article is counted as a halo sale if a customer buys it after clicking an ad for a different item from the same campaign.

This is based on last-click attribution. A sale is credited to the last ad the customer clicked before making any purchase within the 14-day attribution window.

For example, a customer clicks your ad for black jeans but ends up buying blue jeans instead. The sale of the blue jeans is credited to the black jeans' ad as a halo sale and is calculated in the items sold.

This can happen if the customer:

  • Sees the blue jeans as a different colour option on the same product page.

  • Navigates from the ad to their cart and purchases the blue jeans which were already there.

  • Navigates to the blue jeans product page from the black jeans’ page.

Why does my report seem to list fewer articles than before?  

We’ve streamlined the report to focus solely on actively promoted articles. Previously, it included all articles, both promoted and non-promoted halo articles.

For example, you could be advertising 200 articles, but see +4,000 articles listed in your report. The new view exclusively shows data for the articles you are actively advertising to give you a clearer view of campaign performance.

How can I be sure the total sales aren't just organic sales that would have happened anyway? 

Our attribution model follows a strict rule: a sale is only attributed to your campaign if a customer first clicks on one of your ads within 14 days. Organic sales, which have no associated ad click, are never included in your campaign performance metrics. 

Which of the two ROAS metrics is more important? 

Neither direct ROAS nor total ROAS is more important, they have different meanings. 

  • Use Direct ROAS for optimisations, such as deciding if a specific article is profitable enough to keep in your campaign. 

  • Use ROAS total for strategic insights and understand the overall impact of an ad on your brand.

What does it mean if my Direct ROAS is much lower than the ROAS total?

This means the ad is highly effective at generating sales across your overall assortment, rather than just for the specific article advertised. 

It also shows that the advertised articles are powerful products, also called gateway products, which serve as an entry point to your other assortment. They are very effective at bringing customers to your brand, even if they don't buy that specific item. Recognise their strategic value for customer acquisition and judge their success by their high ROAS total.
