Use this when checking metric definitions, formulas, and purposes. *** ## Page-Level Metrics Metrics showing overall page performance. Primarily used in "Numerical Report" and "Smart Summary" tabs. | Metric Name | Definition | Unit | | -------------------- | ----------------------------------------------------------------------------------------------------------------- | ------- | | Visits | Number of site visits (sessions). Multiple visits by the same user each count as 1 visit. | Count | | Unique Users (UU) | Number of people visiting the site within the period. The same user counts as 1 UU regardless of visit frequency. | Count | | Page Views (PV) | Number of times the page was displayed. Each page load counts as 1 PV. | Count | | New Rate | % of new visits in total visits. Calculation: new visits ÷ total visits | % | | Bounce Rate | % of visits exiting from landing page without visiting other pages. Calculation: bounce visits ÷ total visits | % | | Average Stay Time | Average stay time on a specific page. Calculation: total stay time ÷ total PV for page | Seconds | | First View Exit Rate | % of visits exiting from first view (initial visible area upon page load) | % | | Entrances | Number of times this page served as entry/landing page | Count | | Average Page Views | Average number of pages viewed per visit | Pages | | Click Count | Total clicks (PC) or taps (mobile) on page, regardless of link presence | Count | | Click Rate | Click rate for the page | % | | CTA Click Rate | Click rate for CTA (Call To Action) buttons | % | | Conversion Rate | % of visits achieving set site goals. Calculation: conversions ÷ total visits | % | | Completion Count | Number of visits achieving conversion | Count | *** ## Block-Level Metrics Metrics showing performance for each block (section) within the page. Used in "Stay," "Exit," and "Conversion" heatmaps. ### Impression ※PV-based | Metric Name | Definition | Formula | | ---------------- | ------------------------------------------ | ----------------------------------------------------- | | Impression Rate | % of PVs that scrolled to reach this block | PVs reaching block top ÷ total PVs | | Impression Count | Number of times this block was displayed | PVs reaching block top (= impression rate × total PVs | ### Stay ※PV-based | Metric Name | Definition | Formula | | ----------------------- | ----------------------------------------------------------------------------------------------------- | --------------------------------------------- | | Block Average Stay Time | Average time this block was visible in the viewport (seconds). Shows how long users viewed the block. | Sum of block viewport time ÷ impression count | ### Exit ※PV-based | Metric Name | Definition | Formula | | --------------- | ------------------------------------------------------------------------ | --------------------------------------------------------------------------- | | Block Exit Rate | % of PVs viewing this block where it was the deepest reach point on page | PVs with this block as deepest point ÷ PVs viewing block (impression count) | | Exit Count | Actual number of PVs exiting at this block | Exit rate × impression count | ### Conversion ※Session-based | Metric Name | Definition | Formula | | ---------------------- | --------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------- | | Block Conversion Count | Sessions staying 5+ seconds on this block and converting | Sessions meeting dwell condition and converting | | Block Conversion Rate | % of sessions meeting dwell condition that converted. Default condition: **5+ seconds** | Block conversion count ÷ sessions meeting dwell condition (real\_duration ≥ 5000ms) | > **Block Conversion Rate Concept**: Rather than users merely "reaching" a block, it shows conversion % among those who "thoroughly reviewed" the block 5+ seconds. This reveals how much the content impacts purchase decisions. > > **Calculation Unit**: Block conversion rate uses **session basis** (unlike impression/exit rates using PV basis). This is because conversion is determined across the entire session. ### Block-Level Metrics Calculation Unit Summary | Metric Category | Calculation Unit | Target Metrics | | --------------- | ----------------- | --------------------------------------------- | | Impression | **PV-based** | Impression rate, impression count | | Stay | **PV-based** | Block average stay time | | Exit | **PV-based** | Block exit rate, exit count | | Conversion | **Session-based** | Block conversion count, block conversion rate | > Impression, stay, and exit measure behavior per page view, so they use **PV-based** calculation. Conversion determines goal achievement across the entire session, so it uses **session-based** calculation. *** ## Element-Level Metrics Metrics showing performance of individual page elements (buttons, links, images, etc.). Used in "Click" heatmap and "Conversion" heatmap element analysis. | Metric Name | Definition | Formula | | --------------------- | ----------------------------------------------------------------------------- | ------------------------------------------------- | | Click Count | Number of clicks on target element | — | | Click Share | % of total page clicks accounted for by target element | Target clicks ÷ total page clicks | | Visits | Number of visits (sessions) clicking this element | — | | CV Contribution Count | Sessions converting after clicking this element | Sessions converting after element click | | CV Contribution Rate | % of sessions clicking element that converted. **Session-based** calculation. | CV contribution count ÷ sessions clicking element | *** ## Supplementary: Analysis Metrics Used in Smart Summary Smart Summary "Ad Effectiveness Analysis" and "Audience Analysis" use the following concepts alongside page-level metrics above. | Concept | Description | | ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | | Session Count (visits) | Visit count. Calculated on session basis rather than PV or UU. | | Four-Quadrant Classification | Analysis method classifying ad sources or audience segments into 4 groups using 2 axes: visit count (session count) and conversion rate. | | Concentrated | When a specific ad source or segment represents 95%+ of traffic, treated as overall overview rather than comparative analysis. | *** ## Related Pages * [Heatmap Comprehensive Guide](https://gitlab.com/PtmindDev/ptx/ptengine-helps/-/blob/main/DOCS/en/insight/smart-heatmap/overview.md) * [Stay Heatmap](/en/insight/smart-heatmap/stay-heatmap.md) * [Exit Heatmap](/en/insight/smart-heatmap/exit-heatmap.md) * [Click Heatmap](/en/insight/smart-heatmap/click-heatmap.md) * [Conversion Heatmap](/en/insight/smart-heatmap/conversion-heatmap.md)
