How are devices assigned to users?

Our stats show a lot of users with many device IDs. Like 20+. And many Merged IDs.How can I figute out based on what they were merged? It feels unnatural and I want to avoid us having an error in our tracking, missleading the numbers.

Change Amplitude "User ID" for old users

We plan to change the logic of the Amplitude user property "User ID" setup. Previously, we used to pass the value from our backend system there, and now we will start passing the firebase user id. We are planning to rewrite the value of this user property to firebase.user_id for old users (i.e. for all those who will have the "User ID" value before the logic is changed). Can our analytics "break" from changing the values for old users?

Is it possible to group events by properties that are updated after the event?

Hey, In our web app, we trigger a sign-up event the moment a new user signs up. After they sign-up, the user’s properties may get updated as they continue on in our app, for example by filling in their profile information according to what job role they do, which calls a user property update to add these details into amplitude.  I want to create a chart that groups sign-ups by job role (which is only updated after the sign-up event is sent). Is this possible? Our charts can’t seem to do this group by. Everyone’s property is set to (none)—I’m assuming because the property update is only after the event. Any solutions?

Stickiness Curve Weekly Breakdown:

Hey, I was wondering if its possible to view the stickiness curve in a monthly breakdown, but showing weeks instead of days: For example say we are looking at the month of February, Feb 1st - Feb 7th: Week 1 Feb 8th - Feb 14th: Week 2Feb 15th - Feb 21st : Week 3Feb 22nd - Feb 28th Week 4 I see amplitude does it in a weekly breakdown but in a 7-day period. I was wondering if they also did it in a monthly breakdown, but in a 4 week period also, or if its possible to do it that way on amplitude. Thanks!

Group by event properties

Hi all!I’m new to Amplitude. Just tried to push some data and I was successful. I’m especially interested in the event_properties and how I can create some expressive charts around them.However, I don’t see any options to “group by property_x”? For example, let’s say I store a event property“company” for a user. How can I make a chart to group the events by company, so I know which company did create how many events on a daily / weekly level?Here is a sketch :)Can you advise?Thank you!Lukas

User Composition measured by most recent value is wrong

I have a user property called free_trial_group which has 3 possible values (7_days, 30_days and none) and I used it for compositioning: Also I have photos_count user property which I used for segments:  The problem is that values in the resulting pie chart and downloaded users of one of the segments don’t match even though I use most recent value.For exampleI’m downloading those users who have 0 photos_count and are in 7_days free_trial_group:It’s the photos_count column: As you see, almost none of the really has 0 photos_count.Why? Am I doing smth wrong?

What source to use for the new Google Tag Manager Template "Amplitude Analytics Browser SDK"

I send data with GTM and the new Template "Amplitude Analytics Browser SDK", and it works. I see the events as a unknown source.I tried to create it as a source by using the “Google Tag Manager” option but it is stalled at listening for the events coming.I the tried the “Browser SDK” source, but the events send are not automatic detected. I also tried to create a HTTP API source, but with same result.The events i send will not associate them self with the source. How do I ensure that the event form this specific GTM container using the Amplitude Analytics Browser SDK template are recognized as a source, and what source type should I use ? I know i can add a property like “data_source=GTM-W639JT” to all events, but was under the assumption that Sources was to be used for this purpose.

Mismatch in SUM displayed and the summing of events divided by day.

I’m counting uniques performing event Application Installed.In the data table, I see the sum of unique displayed in the first row does not match with the sum of its components. It is 122 # (55+46+14+8)=123.What are potential reasons behind? Any directions I should follow to explore the causes of this mismatch?Thanks everyone!

How to measure CCU with amplitude

Hi all, I’m looking for a solution native to amplitude to measure the concurrent connected users on my platform.Can’t seem to find one, so here to get your feedback and help.I would love to be able to measure: Peak CCU Average CCUI’m almost sure there is a way since amplitude sdk is working and that it’s already listening to a variety of events!

Why are custom events missing standard properties like page_path and page_domain?

My understanding is that if we used the Browser SDK along with the Marketing Analytics SDK, we would get attribution tracking (e.g. UTM params) and the ability to turn on automatic pageview events.However, given discussion in my other question and the benefit of more specific events in amplitude reports, we are implementing custom events for each page view in our site and thus disabling automatic pageview events in the Marketing Analytics SDK.  All good so far.Our custom events are making it through to our development project in Amplitdue but but I’m surprised to see that there are properties missing that I expect to be there like page_path, page_domain which you do get on the automatic generic pageviews if we left that feature on.I then looked at custom events for click tracking we are doing on some buttons and see that they are also missing context of domain and path.No web analytics platform I’m aware of fails to add these properties automatically (which I’d consider essential).

Average Distinct Days per Cohort

Hi, guys I’m having some troubles trying to calculate the average amount of distinct days a cohort of users is active at my app and the compare them. Using SQL will be an easy calculation, but I’m having a hard time trying to deliver this easy calculation.  Would this be something I can set up using custom formulas or other specific analysis chart? Thanks

When shoudl you use flat list of event properties vs object arrays?

Amplitude supports object arrays as event properties as described herehttps://help.amplitude.com/hc/en-us/articles/9623000954907-Cart-analysis-Use-object-arrays-to-drive-behavioral-insights#terms-and-concepts that combined with property splitting seems powerful.  However I’m unclear when it’s best to use this vs a flat list of properties. Is it strictly when you need to represent multiple objects and thus would have repeating of properties forcing you to come up with creative naming to avoid collisions?in our case, say you only even have one subscription plan in a purchase.  Each plan say has a name, term length and price. Also given customers can change plans, we’d want to know the previous plan they are coming from.  is it just better to model event properties like:Event: Plan Purchasedplan_name: silver plan_price: 19.99 plan_months: 1 plan_name_previous: goldor is it better to do:Event: Plan Purchasedplan: { [ name: “silver”, price: 19.99, months: 1 ] } plan_name_previous: goldI ass

My event source is always unknown.

I used @amplitude/marketing-analytics-browser@0.4.0 for tracking my events.When I track my event, the Source of event is always “unknown”.I set Browser SDK Source and I followed the initialization guide faithfully.I set the API_KEY with the key inside the Browser SDK Source page. I don't know why Source is in unknown state. Is there something wrong with my settings?

Users from specific countries are not logged in Amplitude

Hey everyone, We’ve started using Amplitude roughly 3 months ago, and we discovered this week that users from Australia, New Zealand and Ghana (possibly other countries as well) are not being picked up by Amplitude whatsoever. Our other analytics tools are picking them up though, so we’re wondering what could be the issue with the Amplitude implementation that’s stopping us from getting any kind of events from these users. Is it something related to the device locale? is it a bug with Amplitude?  Thanks!Alex

Tracking user scroll

Hi, a team member asked me about tracking scroll events using Amplitude. What is the best practice on capturing events when a user scrolls to a certain part of the page? Let’s say we wanted to have insights into whether users even scroll to the end of a page.Do you think we should do that with Amplitude and what would be the best practice? Thank you Best regards

Creating funnels using number of events rather than type of event

Hi, I’m a new user and happy to be here! I’m trying to create a conversion funnel where I track number of events completed rather than the event itself. So 0-3 actions, 4-6 actions, 7-9 actions etc. Any advice on how to do this would be great.Thanks

Track Landing Pages

Hi all, Newbe here. As far as I understand, Amplitude does not report automatically on web landing pages so trying to find a way to identify them.This is the rationale that makes sense to me:Amplitude init / loads Before sending a page_view event, check if we have previously saved the session ID in browser's local storage. if not, it is a new sessions so we flag the page_view as landing and store session ID from amplitude.getSessionId(); so the next page_view is not identified as such.Does anyone implemented something similar with good results?Thanks in advance.

What are best practices for property naming?

Wondering what is the best practice for property names and if there are advantages to normalizing them across events.For example, imagine I have Event Foo and Event Bar.  Foo is an event involving a product and say Bar is an event involving a category. Which is the best course of action in data modeling in Amplitude:Option 1:Event Foo Property: product_name ​​​​​​​Event Bar ​​​​​​​Property: category_name Option 2: Event Foo ​​​​​​​Property: name ​​​​​​​Event Bar ​​​​​​​Property: name Basically what I’m asking is if there is any benefit to normalizing property names for charting or any other insights? Or is it a better practice to be as specific as possible?  The upside of this latter approach is that when we look at our property list in our data management, it’s really clear what a given property is for without needing to dig into the description.The downside is that there are now N number of properties where as I could instead have a single “name” property for multiple events.
