August
- Public URLs for experiment results – Share experiment results the way you already share dashboards. Generate a public link or an embeddable iframe from the Share modal. You can open a read-only results page with no Optimizely Analytics login.
- Statistical significance notifications – Opt in per experiment to be notified when a metric reaches statistical significance, so you can act without watching the scorecard. Sequential and Bayesian experiments are supported, with one notification per metric and variation combination.
- Custom color palettes – Set an app-wide color palette so every chart matches your brand. Choose from predefined palettes or build and save your own.
- Event usage stats in the event selector – See how heavily each event typeeach event type is used while you build an analysis. The selector shows an average daily count, color-coded so busier events read darker, which makes stale events easy to spot.
- Value counts in column details and filters – Column and JavaScript Object Notation (JSON) field tooltips show the top values, distinct counts, and null percentage, so you can see what a column holds before filtering on it. Distinct-value dropdowns list each value's occurrence count and its share of the column.
- Conversion drivers in Mark – Ask Mark what drove or blocked conversion between funnel steps. Mark returns a link to the conversion driver analysisconversion driver analysis, so you no longer have to build it manually. Supports single segment analyses.
- Mark dashboard actions – Run MarkMark actions on a dashboard from one menu: Summarize Dashboard, Arrange Tiles, and Revert Layout. New Ask Mark entry points in the sidebar and type picker start an exploration without leaving your dashboard.
July
- Unified experiment results page – Added a redesigned experiment results pageexperiment results page. A guided tour walks you through reading and interacting with the page.
- Embedded dashboards – Embed full dashboardsEmbed full dashboards in external sites and tools, so a team reads your dashboard where they already work. Embed URLs include readable parameter and filter names. You can embed visualizations directly from the Share modal through a new Embedding tab.
- Drag-and-drop dashboard tiles – Reorder and resize dashboard tilesdashboard tiles by dragging them, so you can rearrange a dashboard without editing each tile. Grid units appear while resizing, and new tiles land full-width at the bottom.
- First-ever event option for funnels – Count the first funnel stage only when the event is the actor's first-ever occurrence, not just the first within the time range. This isolates new behavior.
- Event occurrence filter for event segmentation – In event segmentation with a Uniques measure, choose how occurrences count: all matching events in the time range, only the first in range, or each actor's first-ever occurrence. This separates new behavior from repeat behavior.
- Inline description editing in explorations – Edit event and custom column descriptions in place from the exploration UI, saved from the tooltip and details views. Context stays current without a trip to the catalog.
- Nested JSON fields in the dataset editor – Drill into JSON-typed columns in the Columns tab to curate their sub-fieldscurate their sub-fields inline, so nested data is as discoverable as a top-level column. Enable or disable fields, set data index, assign categories, and edit descriptions.
- Inline actor lookup – Inspect the individual actors behind a chart without leaving the visualization. A paginated actor table opens inline on a tile, and clicking a row jumps to that actor's details.
- Mark workspace overview – MarkMark now checks which datasets, events, and columns exist before it answers, so its analyses reflect your real workspace instead of assumed structure.
- Mark Structured Query Language (SQL) tool – Mark runs read-only SELECT queries against the warehouse as a last resort when no existing explore type answers the question, returning rows with their schema.
- Automatic experiment pause on a guardrail breach – Opt in per guardrail alertguardrail alert to automatically pause an experiment when a metric breaches its threshold, so a degraded experience stops without waiting for manual intervention.
- Time range filters on scorecards – Apply a dashboard time range filter to narrow an experiment scorecard's analysis window after the fact. You can use it to exclude a day affected by an unrelated site incident.
June
- Conversion drivers – Understand what users did between funnel steps with a beeline analysisbeeline analysis that maps the behaviors driving or blocking conversion, surfacing the events that best explain drop-off after any step.
- Automatic sample ratio mismatch check – Sample ratio mismatch (SRM) is checked automatically when the experiment results pageexperiment results page opens or refreshes, so you no longer need the manual refresh button. Clear Not available states explain when a check is skipped.
- Progressive dashboard filters – Link dashboard filter tiles together so one filter's dropdown narrows based on the selection in another. Filtered dashboards become faster to navigate.
- Public dashboard sharing – Share dashboardsShare dashboards with password-protected links that expire on a date you set. Executives and external partners then view read-only dashboards without an Optimizely Analytics login. Link management includes per-link enable and disable, bulk revoke, and a per-app control to allow or block public link creation.
- Background query refresh – Experiment and exploration results load immediately from cache while a refresh runs in the background, replacing the blank screen you used to see while waiting on recalculation.
- Bulk delete events – Select multiple events in the event catalog and delete them in one action, so cleaning up a cluttered catalog no longer means deleting events one at a time. A confirmation dialog shows how many you are removing.
- Categories and favorites in global search – Global search results show the categories applied to an entity and a star for favorited entities, so you can tell items apart without opening each one.
- Mark engagement analysis – A new engagement tool lets MarkMark analyze event engagement before and after a focal point. For example, compare feature usage two weeks either side of a product launch.
- Mark event measure types – Build analyses through MarkMark using four more event segmentation measure types: Frequency, Active Actor Percent, Intervals Engaged, and Custom Property with percentile aggregation. Mark now covers the measure types you already use in the UI.
May
- Optimizely Analytics Model Context Protocol (MCP) server – Connect your AI tools to Optimizely Analytics through the Analytics MCP serverAnalytics MCP server, so an agent queries your data and builds analyses without leaving the tool you already work in.
- Funnel metrics – Measure sequential event completion as a first-class metric type. Define an ordered sequence of steps and track conversion rates between stages. Funnel measures work directly in experiment scorecardsexperiment scorecards, so you can see how a treatment affects a multi-step journey.
- Automatic CUPED selection – Controlled-experiment Using Pre-Experiment Data (CUPED)Controlled-experiment Using Pre-Experiment Data (CUPED) evaluates results with and without variance reduction in parallel and applies it only when it improves the statistics. Each metric shows whether CUPED was used and why.
- Chart annotations – Add notes directly on time-series chartstime-series charts to capture context around key moments, so the story behind your data travels with the chart.
- Exploration targets – Set a numeric target on any measure and see at a glance whether you are on track. Single value tiles show a progress bar with percent-to-goal, and line or bar chart tileschart tiles show a dashed target line.
- Single value period-over-period comparison – Headline chart tiles display period-over-period changeperiod-over-period change alongside the main metric. The delta value, percentage change, and a directional color indicator show trend direction at a glance.
- Audience conditions in experiment results – The Audiences fieldAudiences field on the experiment results page displays the audience conditions applied to the experiment in a structured tree, giving you clearer targeting context alongside your metrics.
- Experiment conclusions – Concluded experiments surface their conclusion, deployed variation, and conclusion date directly on the results pageresults page, so decision context stays visible without digging through history.
- Refresh experiment results – Fetch the latest experiment results on demand with Refresh resultsRefresh results in the results toolbar, without reloading the full page.
- User visibility controls – Organization admins can toggle whether users see all membersusers see all members of the organization or only those sharing a group, so you can keep membership private in shared environments.
- Case-sensitive contains filter – Configure each column individually for case-sensitive CONTAINS comparisons, which can speed up filtering on warehouses where the default case-insensitive match is expensive.
- Right-click legend highlight – Right-click a series in a chart legend to hide all the others, so you can read one series in a crowded chart. Right-click again to restore full visibility. Works for bar, line, pie, and doughnut charts.
- Persistent column widths – Column width adjustments in data tables are saved, so your layout preferences persist across sessions.
- Event selector usage sorting – Sort the event selector by how often you and your team use each event, so the ones you reach for most surface at the top. Switch to alphabetical anytime, and your choice persists.
- Mark experiment and dashboard tools – MarkMark builds experiment scorecards with specific metrics, adds analyses to an experiment's Explore tab, and adds image tiles to dashboards. Together these enable an end-to-end automated analysis workflow.
- Mark comma-separated values (CSV) upload – Upload CSV data directly to your data warehouse from MarkMark, using inline CSV content or an authenticated file URL, up to 20 MB.
- Mark nested JSON support – Mark tools reference nested JSON column properties in filters, group-bys, and measures. Previously only top-level column IDs were accessible.
April
- CUPED variable configuration – Control variance reduction precisely in experiment scorecards. The CUPEDCUPED settings let you select specific experiment measures and actor-level properties as CUPED variables, replacing the previous on and off toggle.
- Experiment results page redesign – Added a redesigned experiment results experienceexperiment results experience. It adds an experiment time range display, visitor counts, and clearer empty states when data conditions are not yet met.
- Edit explore while querying – Continue refining your explorationexploration configuration while a query is in flight. Changes are preserved without interrupting the running query.
- Mark default app preference – Set a preferred app for MarkMark per user and per organization. Mark resolves to your preferred app without a manual selection step each session.
- Historical event counts timeline – The organizationorganization data usage page loads a time series of historical event counts automatically, so you see ingestion trends without clicking Check data usage.
- Duplicate measure blocks – Copy an existing measure type block in the metric editor to build variations quickly without rebuilding from scratch.
- Formula editor hover cards – Hover over @ mentions in the formula editorformula editor to see entity details without leaving your formula. Slash and quoted names are also valid in variable references.
- Color picker reset – Click Reset to defaultReset to default to return a customized series color to its original, so you can undo a manual color change without rebuilding the chart.
- Events category assignment – Assign raw and clean events to categories directly from the Events page, so you can organize a new event without opening the catalog.
- Collapsible editor pane – Click Hide EditorHide Editor on the experiment results page to collapse the editor and free up horizontal space when you review results. Click Expand Editor to bring it back.
