Funnels, retention and cohorts in nana800 analytics

Where to build them

Open Reports and dashboards in the analytics menu and create a chart. The chart type row has four options: Lines, Bars, Funnel and Retention. Pick a funnel or retention there, and add events as the series of the chart.

A chart can be saved with a name and a description, and the Add to dashboard button attaches it to a dashboard. The dashboard gets the saved version: unsaved changes do not reach it.

Funnel: steps and counting

Funnel steps are the events of the chart in order, from 2 to 20 steps. Each step can have its own property conditions, for example plan equals pro. A funnel always counts unique users.

A person passes a step when they made its event no earlier than the event of the previous step. When two steps in a row use the same event, the second must be later, so one event cannot close two steps. Only events of the chosen chart period count.

• Each step shows the number of people, the share of the previous and of the first step, and how many dropped off.
• The median time from the previous step shows how long people usually take between steps. A separate median covers the first to the last step.
• A click on a step opens the people who reached it. See the guide to chart clicks.

Conversion window

By default the time to go through a funnel is not limited. The conversion window setting offers 1 hour, 1 day, 7 days, 30 days or a custom value in hours or days, from 1 minute to 366 days. Then all steps must be done within that time from the first step, and the best attempt of a person counts.

Mind the edge of the period: people who started in the last days of the chart had no time to reach the end, so the conversion of the last days looks lower.

Retention: how to read the table

The first event of the chart is the start, the second is the return. Without a second event any event counts as a return. A cohort is the people who first made the start event on the same day, week or month. The Day 1 column holds the share of the cohort that came back on the next calendar day, Week 2 on the second week, and so on.

Under the cohort table there is a retention curve of all cohorts. A period that has not come yet is not shown, so fresh cohorts have shorter rows.

• By day: up to 30 return periods and up to 90 cohorts.
• By week: up to 26 periods and up to 52 cohorts.
• By month: up to 12 periods and up to 24 cohorts.

Days, weeks and months follow the time zone of the person who looks at the chart.

Cohorts and user groups

nana800 has no separate page of saved cohorts yet: cohorts live inside the retention report. A group of people is set with a filter. In a chart and on the Users page you can pick the people who have certain user properties or did at least one of the events. The events can carry conditions on their properties.

Say you want to compare the retention of people from ads with everyone else. Keep the first touch tag in user properties as the guide to events and tags shows, then build two retention charts with different filters.

Report limits

Reports are counted from raw events, so they have limits.

• One chart processes up to 2,000,000 events. With more data the web app warns that not all data is shown: make the period shorter or add conditions.
• Retention counts up to 500,000 users.
• Funnel steps and retention events cannot be split by a property, splitting works in lines and bars.
• A ready result is kept for 10 minutes, so opening the chart again is faster.
