Understanding Google Ads metrics in Datadrew
Datadrew pulls key performance metrics from your Google Ads account to give you a unified view of your advertising
performance. This article explains what each metric means and how it helps your e-commerce business.
Core performance metrics
| | | | | --- | --- | --- | | Metric | Definition | Why It Matters | | Spend | Total advertising cost for the selected
period. Google Ads reports cost in micros (millionths of the account currency), which Datadrew converts to standard
currency values. | Your advertising budget baseline. Essential for calculating ROAS and understanding your cost
structure. | | Impressions | The number of times your ads were shown on Google Search, Display Network, YouTube, or
Shopping. | Measures visibility. Compare impressions across campaigns to understand which are getting the most exposure.
| | Clicks | The number of times users clicked on your ads. | Directly measures user interest. Unlike Facebook, Google
Ads "Clicks" typically means clicks to your website. | | CTR (Click-Through Rate) | Clicks divided by Impressions,
expressed as a percentage. | Indicates how relevant your ads are to the audience seeing them. Low CTR may signal the
need for better ad copy or targeting. | | CPC (Cost Per Click) | Spend divided by Clicks. | Your average cost for each
website visit from Google Ads. Compare across campaigns and ad groups to optimize budget allocation. | | CPM (Cost Per
Thousand Impressions) | Cost per 1,000 impressions. Calculated as (Spend / Impressions) x 1,000. | Most relevant for
Display and YouTube campaigns where awareness is the goal rather than direct clicks. |
Conversion metrics
| | | | | --- | --- | --- | | Metric | Definition | Why It Matters | | Conversions | The number of conversion actions
(purchases, sign-ups, etc.) attributed to your ads based on your Google Ads conversion tracking setup. | Your primary
success metric. Ensure your Google Ads conversion tracking is properly configured for accurate data. | | Conversion
Value | The total monetary value of all conversions attributed to your ads. | Represents the revenue your Google Ads
campaigns are driving. Used to calculate ROAS. | | ROAS (Return on Ad Spend) | Conversion Value divided by Spend. |
Tells you how much revenue each dollar of ad spend generates. Compare your Google Ads ROAS with Facebook Ads ROAS in the
Blended Metrics view. | | Video Views | The number of times your video ads were viewed (for YouTube and video
campaigns). | Relevant if you run YouTube or video campaigns. Helps measure brand awareness and top-of-funnel
engagement. |
