To track where users are landing on your product from sources like Instagram, LinkedIn, YouTube, etc., Mixpanel offers several attribution tracking methods:

Mixpanel's JavaScript library automatically tracks UTM parameters and referrer information: 1. UTM Parameters: Mixpanel tracks all UTM tags by default, including: - utm_source: identifies where traffic is coming from (e.g., Instagram, LinkedIn) - utm_medium: identifies the advertising medium - utm_campaign: identifies the specific campaign name - utm_content: identifies specific links within ads - utm_term: identifies keywords associated with campaigns

Traffic Attribution documentation provides details on how these parameters are tracked.2. Referrer Information: Mixpanel tracks Initial Referrer and Initial Referring Domain properties, which show where users first came from before landing on your site.

The JavaScript SDK automatically captures this information. To optimize for attribution models, use this initialization option: LBKSmixpanel.init('YOUR_PROJECT_TOKEN', { stop_utm_persistence: true // disable utm persistence });LBKS

You'll need to manually extract UTM parameters and referrer information from requests. Here's an example in Python: ```from urllib.parse import urlparse

from mixpanel import Mixpanel

mp = mixpanel.init("YOUR_TOKEN")

def track_to_mp(request, event_name, properties): if "Referer" in request.headers: properties.update({ "referring_domain": urlparse(request.headers["Referer"]).hostname })

utm_keys = ["utm_source", "utm_medium", "utm_campaign", "utm_content", "utm_term"] utm_values = {key: request.args[key] for key in utm_keys if request.args.get(key)} properties.update(utm_values)

properties["ip"] = request.remote_addr mp.track(request.user_id, event_name, properties)```

Mobile attribution is more complex: - For Android, you can use Google's Play Install Referrer Library - For iOS, you'll need a mobile attribution partner as the App Store strips referrer dataMobile Attribution documentation recommends using a partner service for reliable tracking, with several integration options available.

Once you've collected this data, you can use Mixpanel's Attribution feature to analyze which sources are driving conversions: - Choose different attribution models (first touch, last touch, linear, etc.) - Set lookback windows - Break down conversions by sourceThis helps you understand which marketing channels are most effective at bringing users to your product.
