Missing Web Events due to Ad Blockers and How to Handle It

Hi there Amplitude Community!When using Amplitude Web SDKs, it is possible that some users’ events are not ingested into Amplitude due to ad blockers. Currently, we are not able to estimate the percentage of events that do not get ingested as we do not have the data to support it. While we do not offer official support for circumventing ad-blockers, our Engineering Team has provided a workaround - run a reverse proxy through your own domain. Please note that it is best that this process is done by an Engineer or a Developer as this is a technical workaround.Details on what a proxy service is and how to use it in this setting can be found here:https://www.docs.developers.amplitude.com/analytics/domain-proxy/Hope this helps! ----- please give this post a thumb-up if you find it helpful! This will help us know what content we should publish in the future :) -----Amplitude Team

Instrumenting the Duration Event Property

Media customers that are interested in tracking the amount of time users spend on their products would be interested in instrumenting a property that measures the duration between two events. With this property, users can then measure various items such as Average Property Value, Median Property Value, or use the duration values in complex formulas in our Event Segmentation: Formulas chart.  To track duration, you would need to capture the timestamp of a Start Event and timestamp of an End Event, calculate the difference between the two timestamps, and then pass in the duration as an event property for the End Event. In our demo account this End Event is called Played Song, and here is an example chart: https://analytics.amplitude.com/demo/chart/new/snewb09  As an example for Page View events, let's say you have a Start Event = 'Viewed Home Page' and an End Event = 'Clicked Signup'. When the user fires the 'Viewed Home Page' event, you can create a variable in your code called first_ti

Seeking Strategies for User Conversion Analysis in E-commerce with Common Landing Pages

Our company is operating an e-commerce platform, and we're trying to use the 'page_name' property of the page view event to group and see which pages have a high purchase conversion rate. Amplitude aggregates data based on the first page view shown, and due to the nature of our e-commerce, which has several common landing pages, it's challenging to identify the actual converting pages using the usual funnel analysis (there are so many pages after landing). We're unable to see the conversion rate per user when we hold the 'product_id' as a constant property, as the conversion rate is then divided by the number of products shown. We want to analyze when the product shown on the page and the purchased product are the same. How can we view the purchase conversion metrics based on the same 'product_id' while also being able to see the purchase conversion rate per user? I've been searching for a method for three days but haven't found an effective solution. Even a small piece of advice would

Excluding Facebook social sign-in from referrals

As new Amplitude users we noticed a weird pattern in our attribution data where Facebook.com and accounts.google.com were being attributed as referrers for a significant number of our registration events.We quickly realised that when our users opted to authenticate via Google or Facebook’s social sign-in, they were temporarily leaving our domain to go to the respective site to give us permission to authenticate. When they come back to our domain, despite it still being the same session, Amplitude is overwriting the true attribution data e.g. referrer, referring domain, UTMs, etc, with either facebook.com or accounts.google.com.We’ve excluded accounts.google.com as a referrer which neatly solves that one. Annoyingly as visitors who come from Facebook appear as facebook.com regardless of whether they clicked on a link, or came via the authentication page there’s no way to exclude that domain without losing attribution on genuine organic FB registrations.We’ve been speaking with Amplitude

New User Pathfinder

I am currently trying to create a pathfinder analysis to answer the questions: What is the typical journey for new users?. When I was designing the pathfinder I saw that there is an event called ‘New User’. After further research I understood that the new user event is:A user’s first event in Amplitude A new user is a user who has logged an event to Amplitude for the first time (this includes inactive events). The time of when the user is new is the time of when they logged their earliest eventWith this information I created a Pathfinder that starts with Start Session. For the User I selected for users that performed New User and was then prompted with “who performed user = x time. I started changing the operator and number and saw that with each change the number of Start sessions changes. I don’t understand how the event New User can be equal any number if it is defined as the first event of a user and how I can make the parameters New User > 4 means or New User = 0. I would appre

difficulties in funnel analysis

The article (https://help.amplitude.com/hc/en-us/articles/19466710221979-View-funnel-conversion-by-event-property-values) says "If users in your funnel can complete the steps multiple times, this method will take the first occurrence of each event and bucket the user for the value on that event". And I want to know the conversion rate with taking the last occurrence of each event, not the first occurrence.And other article says "If, however, you opt to hold properties constant, the funnel chart will display the unique count of user and user/event property pairs that have completed the funnel. If a user goes through the entire funnel X times with Y distinct event property values, the user will be counted Y times." But I want to know the conversion rate of distinct user using hold properties constant (not the value of divided by number of property values) . Is there any way to resolve these issues?Thank you.

Track Amplitude Conversions in Google Ads

I’ve followed the instructions to use an event stream to push conversion events from Amplitude to Google Ads which can then be used to optimize my campaigns by following the instructions here: https://www.docs.developers.amplitude.com/data/destinations/google-ads-event-streaming/. However, I cannot get the settings to pass the validation when I test the connection.I’m getting tripped up by the Google Cloud Service Account field and what to put in there. The instructions say “Enter your Base64 encoded Google Cloud Service Account.” and the link references the service account you need to create in Google Cloud Console. I’ve created this account and downloaded the appropriate json file, but it’s not clear what needs to be input into the Google Cloud Service Account field. I tried encoding the json file in Base64 and inputting that and I’ve tried the private key information (both encoded and not). None of which work. I get two kinds of errors...When I input the entire base64 encoded json f

Freemarker syntax for accessing item in array

I am trying to create a custom payload for my Webhook destination. The input event payload has an array of items and I always want to access fields in the first item of the array. I am able to successfully test the connection if I only access the first item of the array, but when I try to access properties within that item, I get a configuration error. "${input.events[0].event_type}"Leads to the error belowThere was an issue with sending your test event.Invalid payload or configuration. But "${input.events[0]}"does not lead to any errors. This suggests that accessing the item using the index works correctly, but I can’t find any documentation out there on how to access the properties within that item. For reference, this is the input event. I redacted some private information. This is an integration between RevenueCat and Amplitude, I need to forward some of this info to another service (Singular) which Amplitude does not have an integration for.{ "api_key": <redacted>, "events

Filter out/group page events with unique strings

We have a ton of Unexpected events generated from varying page views with unique strings attached that I can’t seem to clean out/block future.I feel like it should be pretty simple to create a filter and auto block, but there is no way I can see to program a ‘contains’ in URL for filter configuration.So some examples, I just want to filter out events with /app/chat/*/ and the like programmatically.Or on the same notion, create a rule to group to 1 event based on a url path, i.e. /app/{UID}/goals/*/comments = Comment Viewed vs /app/{UID}/goals/*/home = Goal Viewedfyi @Esther Trapadoux  Sample of this undesirables:

Can't stop "[Amplitude] Application Backgrounded" without stopping "[Amplitude] Application Installed"

I had to delete the event "[Amplitude] Application Backgrounded" because it was triggering 30x/user/day, but I would like to keep “[Amplitude] Application Installed". When you delete an event, Amplitude says “You should also update your instrumentation to stop sending the deleted event type (https://app.amplitude.com/analytics/play2pay/chart/spv718cg/edit/s9rk1iev?source=copy+url) but AFAIK, there’s no way to update the SDK instrumentation (using appLifeCycles = false) without also blocking “[Amplitude] Application Installed", correct?
