GA4 Optimizer Documentation

GA4 Optimizer aims to solve common analysis needs when using Google Analytics™ 4 interface. This guide explains what each feature does and how to use it. Please note that as Google Analytics 4™ interface changes some of these features may stop working.

Quick Access to Settings: Most features can be toggled on/off from the popup. Features with more detailed configurations (like "Click to Copy" actions or "Date Range Presets" visibility) have a settings option in the popup. Clicking this will open a dedicated settings page.

Looking for a Quick Overview? Visit our features page for a concise summary of all capabilities.

1. Click to Copy Cell

Applies to: Explorations & Standard Reports
Quickly copy values from table cells, headers, or dimension labels to your clipboard. Detailed click behaviors (single, double, triple) can be configured by clicking the Settings button in the popup.

  • Single Click (if enabled): Copies the text of the specific line you clicked within a cell.
  • Double Click (Explorations Only, if enabled): Copies the entire text content of the clicked cell or label, automatically adding spaces where lines wrap.
  • Triple Click (Exploration Data Cells Only, if enabled): Copies the combined text content from the hover tooltip.
Note: Copying complex multi-line text from Explorations might occasionally miss or add a space. Manual selection is always an option.

2. Sticky Report Header

Applies to: Standard Reports Only
Keeps the header row visible while scrolling, making it easier to analyze long reports without losing track of metric columns.

  • When scrolling down a long table in a Standard Report it's hard to know which metric you're looking at. This feature keeps the header row fixed at the top.
  • NEW: The search box and pagination controls are now sticky to the bottom when scrolling for easy access. There is an option in the settings to turn this off if needed.

3. Highlight Sampling

Applies to: Explorations & Standard Reports
Instantly see when your data is sampled. This feature makes the data quality icon pulse so you're always aware of potential data inaccuracies.

4. Percentage Change Highlighter

Applies to: Standard Reports Only (when date comparison is active)
Uses conditional formatting to highlight significant positive or negative trends based on user-defined ranges and colors. Configure ranges, colors, and highlight source in settings.

5. Δ% Share Change (Reports)

Applies to: Standard Reports Only (when date comparison is active)
Calculates and displays the percentage change of the "percentage of total" values directly in the "% change" row, providing deeper context than standard % change.

Note: This feature relies on the presence of the "percent-of-total" spans (e.g., (XX.XX%)) generated by GA4 in the data rows. If these are missing or GA4 changes their structure, this feature may not work.

6. Percentage of Column Total

Applies to: Explorations Only
On hover, this instantly calculates each row's percentage contribution to the column total, ideal for quick contribution analysis.

Note: If the "Total" row is scrolled out of view, percentages might temporarily show "Scroll up to capture Column's Total" or be based on the last known total.

7. Detailed Results Shortcut (Beta)

Applies to: Explorations Only
Manually trigger "More detailed results" (less sampling) in Explorations using a keyboard shortcut for better accuracy. Configure manual or automatic activation modes in settings.

Requirement: This feature must be enabled in the popup and you must be on an Exploration page.
  • Keyboard Shortcut: Press Ctrl+Shift+Q (Windows/Linux) or Command+Shift+Q (Mac) while on an Exploration page.
  • When to Use: Use this when you see a sampling icon (⚠️) in your Exploration, indicating that the data is sampled.
  • What it Does: Attempts to switch the Exploration to use "More detailed results" which provides less sampled data.

8. Percentage of All Users

Applies to: Explorations Only
Quickly calculate and compare user conversion rates for different segments against the total user base, simplifying funnel and segment performance analysis.

Requirement: The 'All Users' segment or any segment containing "All users" must be included in your Exploration table setup.
Visibility Requirement: If the 'All Users' column is scrolled out of view, the conversion rate might be unavailable or show 'N/A'.

9. AB Test Segment Comparison

Applies to: Explorations Only
A powerful tool for conversion rate optimization (CRO) that compares metrics between test variations, calculates statistical significance, and checks for sample ratio mismatch (SRM).

Requirement: Segments must be named with `VAR-` prefix, and the control segment must start with `VAR-Control` (case-sensitive).

How it Works

  • Automatic Activation: The moment your Exploration contains correctly named segments, the feature activates automatically.
  • At-a-Glance Icons: The feature places minimalist arrow icons directly inside the cells of your variant segments.
  • Visibility Toggle: A new 'eye' icon appears in the top-right of the GA4 interface.
  • Detailed Hover Tooltip: Hovering over any cell provides detailed tooltip with exact percentage differences and statistical significance.

10. Exploration View Enhancer

Applies to: Freeform Explorations Only
A comprehensive suite of tools designed to maximize your productivity when working with GA4 Freeform Explorations. Combines three powerful sub-features: Collapsible Panels for screen real estate, Maximize View for instant data density optimization, and Pagination Controls for effortless navigation through large datasets. Additionally, hover over exploration tabs to see full tab names when they're truncated.

10a. Collapsible Panels

Adds toggle buttons to collapse/expand the "Variables" and "Tab Settings" panels in Explorations, giving you maximum screen real estate for your data table.

  • Chevron buttons appear on the left side of the Exploration table to minimize/expand the Variables and Settings panels.
  • Collapsed panels stay collapsed as you navigate between Explorations (optional setting).
  • Provides more horizontal space for viewing wide tables with many columns.
Tip: If the buttons are misplaced or missing after a GA4 update, try refreshing the page.

10b. Maximize View

Instantly optimize your Exploration view to display the maximum amount of data with a single click or keyboard shortcut. Automatically sets "Show rows" to 500 and "Show column groups" to 20.

  • One-Click Activation: Click the "Maximize View" button that appears in your Exploration interface.
  • Keyboard Shortcut: Press Shift+M to instantly maximize your view.
  • Smart Panel Handling: If the Settings panel is collapsed, Maximize View automatically expands it, applies the changes, and optionally re-collapses it.
  • Auto-Maximize Option: Enable "Auto-maximize on load" to automatically apply Maximize View whenever you open a Freeform Exploration.
  • Tab Tooltips: Hover over exploration tabs to see full tab names when they're truncated.
Availability: This feature only works on Freeform Explorations. Other exploration techniques (Funnel, Path, Cohort, etc.) are not supported.

10c. Pagination Controls

Navigate through large datasets effortlessly with an intelligent pagination system that overlays intuitive controls on your Exploration canvas.

  • Floating Pagination Bar: A sleek pagination bar appears at the bottom-center of your Exploration table, showing your current position (e.g., "Rows 1-500") with navigation controls.
  • Next / Previous Buttons: Advance or return through row sets without opening the Settings panel.
  • Rows Per Page Dropdown: Quickly change how many rows to display (10, 25, 50, 100, 250, or 500).
  • Keyboard Shortcuts:
    • Alt+→: Navigate to next page
    • Alt+←: Navigate to previous page
    • Alt+Home: Jump to first page
    • Alt+End: Jump to last page (when detectable)
Availability: This feature only works on Freeform Explorations. Other exploration techniques (Funnel, Path, Cohort, etc.) are not supported.

11. Sticky Conversion Calculator

Applies to: All Google Analytics 4™ Pages
A quick-access calculator for common marketing calculations like conversion rate or CPC, available anywhere in the GA4 interface. Calculate two CRs and compare them with absolute difference and relative uplift.

  • A calculator icon appears in the bottom-right. Click to open.
  • Calculate two CRs (CR1, CR2) by entering Conversions and Total.
  • Compares CR2 vs CR1 (Absolute Difference, Relative Uplift).
  • Panel header is draggable. Click icon or "X" to close.

12. Date Range Presets

Applies to: Standard Reports Only
Adds quick-select buttons for common date ranges (e.g., 7D, 30D, LM) and comparisons (e.g., LM MoM), plus a powerful Compare button with three comparison modes for instant, accurate date comparisons. Customize visible presets and their order by clicking the Settings button in the popup, or by clicking the gear icon next to the presets on the GA4 page.

  • Preset buttons appear next to the date picker in Standard Reports.
  • Clicking a preset applies it and reloads the report.
  • If many presets are visible, a scrollbar appears in the preset area.
  • Comparison presets are hidden on Advertising pages.
  • Compare Button — Three Powerful Modes: A dedicated Compare button appears alongside the presets with three distinct comparison modes:
    • Click (no modifiers): Applies "vs. Previous Period" comparison with weekday alignment for accurate period-to-period analysis.
    • Shift + Click: Applies "vs. Last Year" comparison using exact calendar dates for simple year-over-year analysis.
    • Ctrl + Shift + Click (Cmd + Shift on Mac): Applies "vs. Last Year (Day of Week Aligned)" for the most accurate year-over-year comparison that accounts for weekday shifts.
    • Smart Override: Clicking with any modifier key instantly switches to that comparison mode, even if another is already active.
    • Toggle Off: Clicking the same mode again removes the comparison entirely.
Why Weekday Alignment Matters: When comparing periods year-over-year, calendar dates don't always align with weekdays. For example, Jan 15–21, 2024 runs Monday–Sunday, but Jan 15–21, 2023 runs Sunday–Saturday. This misalignment can skew metrics that vary by day of week. The "Day of Week Aligned" mode automatically adjusts the comparison period so weekdays match perfectly.
Tip: Hover over the Compare button to see all three modes at a glance. As you hold modifier keys (Shift, Ctrl/Cmd), the tooltip updates to show exactly what will happen when you click.

13. Quick Calculated Metric

Applies to: Standard Reports & Explorations (Table Visualization)
Create calculated metrics (rates, ratios) directly in your reports without using GA4 Admin settings. Save to your library for reuse across reports. NEW: Right-click segment headers in Freeform Explorations to compare all metrics across segments instantly!

Note: In Explorations, this feature only works with Freeform technique using Table visualization. It will not activate in other exploration types (Funnel, Path, etc.) or visualizations (Line chart, Bar chart, etc.).

In Standard Reports

Adds a new column to your report table for calculated rates.

  • Click + Add calculated rate in the new column header.
  • Select numerator and denominator metrics from dropdowns.
  • Choose display format (Percentage or Decimal).
  • Optionally save to library and set auto-apply preferences.
  • Use the pencil icon to edit, plus (+) icon to add more columns. Manage saved rates in Settings → Global Features.

In Freeform Explorations (Table Only)

Calculated rates appear in hover tooltips. Create them by right-clicking metric or segment headers.

  • Metric-Based Calculations — Best for conversion rates, engagement rates (e.g., Conversions ÷ Sessions): Right-click a metric header, select "Create from '[Metric Name]'...", choose denominator and format.
  • Segment-Based Calculations (NEW) — Best for segment penetration, cohort analysis (e.g., Mobile Users ÷ All Users): Right-click a segment header, select "Create rate from '[Segment Name]'...", choose denominator segment. Calculation applies to all metrics in that segment.
  • Saved metrics auto-apply when their numerator and denominator are present. Manage all saved calculations in Settings → Global Features.
Note: Saved calculated metrics are available for quick access and management in the settings page. Temporary (on-the-fly) calculations are only for your current view and will be cleared when the page reloads.

14. Line Chart Color Customization (Beta)

Applies to: Standard Reports & Explorations
Customize the colors of line charts and add hourly granularity to Standard Reports. Click the palette icon near charts to customize colors, or use the new "Hour" option in the time interval dropdown for detailed hourly analysis.

Note: While this feature works in both Standard Reports and Explorations, Google Analytics' rendering behavior in Standard Reports can sometimes be inconsistent, especially when a "Total" series is included.

15. Fix Shared Links

Applies to: All Google Analytics 4™ Pages
Shared GA4 links often open with a "Missing permissions" error or are redirected to the welcome page — not because you don't have access, but because the link opened under the wrong Google account. This feature detects that situation and automatically finds the right account for you.

When This Helps: A colleague sends you a GA4 link, but you're signed into your personal Google account instead of your work one, or you have multiple work accounts with different property access.

How it Works

  • When GA4 shows a "Missing permissions" error or redirects to the Welcome to Google Analytics page, the extension detects it automatically.
  • It allows you to scan all your signed-in Google accounts to find which one has access.
  • Once it finds an account with access, it opens the previously attempted link under that account.
  • Share the extension with your stakeholders to prevent them from complaining that they can't access your links!

Smart Share Link Button

This feature also adds a "Copy smart share link" button to the GA4 Optimizer toolbar on Standard Reports, Advertising, and Explorations pages.

  • Auto-Cleans the URL: Automatically strips the ?authuser= parameter that GA4 adds to URLs, which can force recipients into the wrong Google account and cause instant "Missing permissions" errors.
  • Includes a Helpful Note: Along with the clean URL, the clipboard text includes a short professional note with a link to the extension, giving your client an instant lifeline if they get stuck.
  • Exploration Workflows: If an Exploration hasn't been shared natively yet, the button first triggers GA4's native share flow, then copies the clean URL and note to your clipboard.

16. Create Exit Pages Report

Applies to: All Google Analytics 4™ Pages (via Popup)
Instantly generates a new Standard Report template pre-filled with Exits, Views, and Bounce Rate metrics, using Page Path as the primary dimension. This feature provides a crucial workaround, as the "Exits" metric is not available in the standard GA4 Report Builder UI.

Note: This feature requires you to have at least Editor Role Access and to be on a page within a GA4 property (i.e., the URL must contain a property ID like "/p123456789/"). The button in the popup will be disabled if you are not on a valid GA4 page.
  • How it works: When you are on any GA4 property page, open the extension popup, navigate to the "Reports" tab, and click the "Create Exit Pages Report" button.
  • Your current tab will be redirected to the GA4 "Create a new report" screen, with the necessary (and normally unavailable) metrics and dimensions already selected for you.
  • You can then save this report to your library for future use. The Exit Rate column will automatically appear thanks to the calculated metric.

17. Custom Definitions Copy/Paste

Applies to: GA4 Admin > Custom Definitions Page Only
Copy custom dimensions, custom metrics, and calculated metrics between GA4 properties. Perfect for setting up new properties, migrating configurations, or maintaining consistency across multiple properties.

Requirements: Must have Editor or Administrator role on both properties. Must be on the Admin > Custom definitions page in GA4.

How to Use

  • Copy from Source Property:
    • Go to Admin > Custom definitions in your source property.
    • Click the tab for what you want to copy (Custom dimensions, Custom metrics, or Calculated metrics).
    • Click the "Copy [Type]" button with the GA4 Optimizer logo.
    • Wait for "Copy completed successfully" message.
  • Paste to Destination Property:
    • Go to Admin > Custom definitions in your destination property.
    • Click the matching tab for what you copied.
    • Click "Paste [Type]" button (shows how many items are available).
    • Review what will be created and click "Continue".

Key Features

  • Smart Duplicate Prevention: Automatically skips items that already exist.
  • Multi-Type Clipboard: Copy dimensions, metrics, and calculated metrics separately — the system remembers all of them.
  • Progress Tracking: Shows real-time progress with option to cancel long operations.
  • Handles Large Datasets: Works with hundreds of items across multiple pages.
Important Notes: Calculated Metrics — only name and formula are copied; you'll need to set formatting (currency, percentage, etc.) manually. Works within your GA4 property's limits (Standard: 50 each, GA4 360: 125+ each). GA4 creates new API names automatically in the destination property.

18. 500 Rows per Page

Applies to: Standard Reports Only
GA4's "Rows per page" dropdown maxes out at 250 by default. This feature adds a 500 option so you can see twice as many rows without paginating — ideal for large reports where you need the full picture at a glance.

  • Open any Standard Report and scroll to the bottom of the table.
  • Click the Rows per page dropdown — you'll see a new 500 option with the GA4 Optimizer icon next to it.
  • Select it. The page reloads with 500 rows displayed.
  • A confirmation toast appears at the bottom of the screen reminding you that larger row counts may slow the page down.
Performance note: Loading 500 rows asks GA4 to process significantly more data than the default 10. On reports with many metrics or complex filters, the page may take a singnificantly longer to load and may even result in unresponsive page. There is a good reason why Google did not want this option accessible by default but we're making it accessible for power users.

Troubleshooting

Ensure you are on the correct page type (Exploration or Standard Report). Try refreshing the GA4 page using the button in the popup or your browser's refresh. Double-check the feature is toggled on in the popup.

The GA4 interface might have changed. Check for extension updates or report the issue. For "Percentage of Column Total", if "Total" row is scrolled out of view, data might be unavailable. For "Percentage of All Users" or "AB Test Segment Comparison", if 'All Users' or 'VAR-Control' columns are out of view, data may be unavailable.

Ensure feature and desired click actions are enabled in settings (by clicking the Settings button in the popup). Complex Exploration tables can be tricky; manual selection might be needed.

  • Verify exploration type: This feature only works in Freeform Explorations with Table visualization.
  • Check segment naming: must start with VAR-, control with VAR-Control (case-sensitive).
  • Ensure variant and a matching control segment (same metric) are in the table and visible.
  • Control segment's value must not be zero/non-numeric for count comparison.
  • For Δ%Shr comparison, both variant and control cells need valid, non-zero column totals.
  • Statistical significance requires column totals to be visible for all variants and sample sizes to be adequate (n > 30).
  • General: Ensure you are on a Freeform Exploration page. This feature does not work on other exploration techniques (Funnel, Path, Cohort, etc.) or Standard Reports.
  • Master Toggle: Check that "Maximize View" is enabled in the popup. Individual sub-features (Collapsible Panels, Maximize View, Pagination) also have their own toggles in the settings page.
  • Collapsible Panels: If the chevron buttons are misplaced or missing, try refreshing the GA4 page.
  • Maximize View: If the button doesn't appear or Shift+M doesn't work, ensure the feature is enabled and you're on a Freeform Exploration.
  • Pagination: If the pagination bar doesn't appear, verify you're on a Freeform Exploration, ensure the Settings panel is expanded, and check that pagination is enabled in settings.
  • Pagination Buttons Disabled: If pagination buttons are grayed out, expand the Settings panel — pagination requires access to GA4's "Start row" and "Show rows" inputs.
  • Keyboard Shortcuts Not Working: Ensure you're not typing in an input field when pressing shortcuts.
  • Ensure you are on a Standard Report page. Try refreshing the GA4 page.
  • Check the feature is enabled and configured in settings (by clicking the Settings button in the popup).
  • Visual overlaps with sticky header might occur; try toggling sticky header or refresh.
  • In Standard Reports: The feature adds a new column. If it's not there, refresh the page. Both the numerator and denominator metrics must be present as columns in the report.
  • In Explorations: Verify you're using Freeform technique with Table visualization. The feature will not work in other exploration types or visualizations. It works via right-clicking a metric header. Both the numerator and denominator metric columns must be present in your Exploration table for the same segment.

This can happen in Standard Reports due to how GA4 renders its charts. GA4's code can sometimes override the custom colors after a moment, most commonly when a "Total" line is included. The feature works most reliably in Explorations. If colors don't apply, try refreshing the page or toggling the "Total" series off in the GA4 report settings.

  • Ensure the feature is enabled in the popup (Global tab).
  • The scan only triggers when GA4 shows a "Missing permissions" error. If you already have access, nothing will appear — that's expected.
  • If the scan ran but found no matching account, none of your currently signed-in Google accounts have access to that property. Use the "Log in to another account" link in the dialog to add the right account.
  • If the dialog appeared but the scan didn't start automatically, try refreshing the page and opening the shared link again.
  • Buttons not appearing: Ensure you're on the Admin > Custom definitions page in GA4. The feature only works on this specific admin page.
  • Copy operation fails: Verify you have Editor or Administrator role on the source property and that there are items to copy on the current tab.
  • Paste button disabled: Make sure you're on the correct tab for the data you copied. The paste button only enables when there's matching data for the current tab.
  • Paste operation interrupted: If your computer locks or the browser becomes inactive, look for a recovery modal when you return. You can resume, start over, or cancel.
  • Large datasets timing out: For properties with 50+ items, the operation may take several minutes. The system automatically prevents computer sleep on supported browsers.
  • Storage quota errors: The system automatically switches to local storage for large datasets. Clear your browser's extension data if issues persist.
  • Feature not enabled: Check that "500 Rows per Page" is toggled on in the popup under the Reports tab.
  • Wrong page type: This feature only works on Standard Reports. It will not appear in Explorations, Admin pages, or the GA4 home screen.
  • Option not visible after enabling: Close and reopen the dropdown. The option is injected when the dropdown opens, so it won't appear in a dropdown that was already open when you enabled the feature.
  • Page loaded slowly: On slow connections, the option may take a moment to appear. Close and reopen the dropdown if it's missing.
