This page defines the metrics that are specific to Epsilo. Standard ad metrics such as impressions, clicks and CTR follow each network's own definition. ## How it works **1. Networks send the raw numbers** Spend, Ads GMV, orders, clicks and impressions come from each ad account you connect. **2. Epsilo adds its own reads** Metrics such as Ad live time, Missed GMV and Suggested budget are worked out by Epsilo from that data. **3. Every surface uses the same names** Pick any metric in a table, a Senses report or a Console answer and it means the same thing. ## Use it ### Core metrics | Metric | What it means | | - | - | | **Ads spend** | What your ads cost in the period. | | **Ads GMV** | Sales the network attributes to your ads in the period. | | **ROAS** | Ads GMV divided by Ads spend. | | **Orders** | Orders the network attributes to your ads. | | **CPO** | Ads spend per order. | | **Share of spend** | An account's or platform's share of the book's spend. | | **Runway** | How many days the ad wallet lasts at the current spend. Sort Portfolio by **Runway (soonest first)** to see who runs out first. | ### Ad live time **Ad live time** is the share of the period the ad was actually serving, instead of going dark on budget, stock or a pause. Higher is better. Where you see it: * As a column and a sort in Campaigns, on campaigns and ad objects. * As the **Low live time** health filter in Campaigns. * As the impact on each row in [Apply now](https://epsilo.ai/docs/portfolio/apply-now.md), where the goal is 100%. * On Home, beside the accounts losing the most. ### Performing time **Performing time** is a column in campaign and ad object tables. Read it next to Ad live time: an ad can be live but not spending, and Performing time shows how much of the live time turned into delivery. ### Missed GMV **Missed GMV** is an estimate of the sales lost while an ad was not live, for example when it paused, ran out of budget or ran out of stock. It is worked out by Epsilo from the ad's own pace, not reported by the network. Lower is better. Where you see it: * On ad account cards and as a sort in Portfolio. * As a column on campaigns and ad objects. * As the consequence on each row in [Apply now](https://epsilo.ai/docs/portfolio/apply-now.md). * On Home, in the zones that rank what is costing you most. ### Suggested budget **Suggested budget** is the daily budget Epsilo projects a campaign needs to stay live through the whole day at its current pace. It is a suggestion; nothing changes until you apply it. Where you see it: * In [Apply now](https://epsilo.ai/docs/portfolio/apply-now.md), where you apply it in one click. * As the **Suggested budget** health filter in Campaigns. * As the **Below suggestion** health chip on an ad account in Portfolio. * As a metric in [Senses](https://epsilo.ai/docs/portfolio/senses.md). ### Budget out When a campaign's budget runs out for the day, its ad account shows the **Budget out** health chip, titled **Budget exhausted today**. Raise the budget, or let a budget distribution move money to it. See [Automations](https://epsilo.ai/docs/automation/automations.md). ### Search demand **Total daily searches** in [Keyword lab](https://epsilo.ai/docs/portfolio/keyword-lab/key-concepts.md) is daily searches for a keyword over the last 7 days, summed across the platforms you picked. It is market demand, not your ad results. ### Digital shelf These metrics measure how visible your products are on the marketplace shelf. They appear in automation templates. To see the shelf product by product, open [Digital shelf](https://epsilo.ai/docs/portfolio/digital-shelf.md). * **Share of search**: your share of sponsored impressions on your target keywords. * **Share of shelf**: your share of sponsored slots on the category shelf. ### Benchmarks in Senses A Trend report in [Senses](https://epsilo.ai/docs/portfolio/senses.md) can add **Total**, **Growth**, **Avg per period**, **Avg daily**, **Avg BAU day**, **Avg Double Day** and **Peak day** beside each row. ## Ask Botep ```text theme={"system"} Which campaigns had the lowest Ad live time yesterday, and what did it cost in Missed GMV? ``` ```text theme={"system"} Explain how ROAS changed for my Shopee accounts this week. ``` ## FAQ > [accordion] Why doesn't Missed GMV match anything in Seller Center? > > Missed GMV is Epsilo's estimate of sales you did not get.
