In Ptengine Experience, you can set the following two types of goals: Access to a specific page URL Example: Member registration completion page, purchase completion page, etc. ``` Counting method: 1 count per visit to the specified page ``` Event occurrence Occurrence of a pre-configured Ptengine event ``` Counting method: 1 count per event occurrence ``` ๐Ÿ’ก For more details on goals, please also refer to the ["What is a Goal?"](/en/experience/glossary.md) documentation. ## **Goal Reaching Unique Users** ๐ŸŽฏ Goal Reaching Unique Users (Goal Reaching UU) refers to the number of unique users among those who viewed an experience who reached the set goal. ๐Ÿ“Œ Important conditions: To be measured as Goal Reaching UU, the experience must be displayed within the same session. ๐Ÿ’ก How measurement works: Experience is displayed to the user Goal is reached within the same session Counted as Goal Reaching UU โŒ Cases where measurement does not occur: User leaves after experiencing the interaction, and reaches the goal on a revisit without the experience being displayed โœ… Cases where measurement exceptionally occurs: The session ends while the page remains open in the browser When returning to the page afterward and meeting the following conditions Page editing: Click or scroll ``` Web engagement: Click on popup or fixed bar ``` ๐Ÿ” Notes: The number of "Users who reached the goal" on the goal list screen may differ from "Goal Reaching UU" in the experience report. Goal list: The pure number of users who reached the definition, regardless of experience display Experience report: The number of users who reached the goal within the same session after the experience was displayed Understanding this difference enables more accurate analysis. ## Goal Rate Goal Rate shows the percentage of users who reached the set goal among those to whom the experience was displayed. Calculation formula: Number of Goal Reaching Users รท Number of Impression Users ร— 100% ## View Conversion Rate / Click Conversion Rate Experience Goals support an "attribution mode" (switch it under the goal's **Advanced settings**), and the conversion metric in reports changes accordingly: * **View Conversion Rate**: the percentage of users who reached the goal after seeing the experience; the denominator is Impression Users (the same basis as "Goal Rate" above). * **Click Conversion Rate**: the percentage of users who reached the goal after clicking a button/link in the experience; the denominator is interaction UU (users who clicked a button/link in the experience). Experiences without clickable elements (inline / redirect, etc.) do not offer the mode switch and continue to display as "Goal Rate." Click Conversion is measured using data from June 22, 2026 onward. ## Average Session Duration Represents the average time from when an experience is displayed until the user transitions (leaves) to a page not measured by Ptengine. Calculation formula: (Total session duration after experience display) รท (Impression Unique Users) ## Average Page Views The average number of page views from when an experience is displayed until the user transitions (leaves) to a page not measured by Ptengine. Calculation formula: (Total page views after experience display) รท (Impression Unique Users) ## Bounce Rate Shows the percentage of users who leave without transitioning to other pages being measured by Ptengine after the experience is displayed.
