The Referrer Tracker V4 module can be used in tracking and analytics of your referral data, which is easily integrated into OpenCart and gives the information on where customers get to your site, which country they belong to, and which campaigns or sources have the most conversions. It is handy in digital marketing campaigns, social media promotions, affiliate programs, and paid advertisements.

Key Features of Referrer Tracker V4

1. Source Identification and Tagging: Referrer Tracker V4 tracks and segments all incoming traffic by source (e.g., Google, Facebook, Instagram, Email Campaigns). All referral sources are tagged so you can easily segment the traffic and determine high-performing sources.
2. Custom Campaign Tracking: The module allows for UTM parameters. It can create custom tracking URLs for your campaigns, promotions, or influencers, enabling you to find out which efforts generate the best ROI.
3. Real-Time Analytics Dashboard: Users will be provided with an intuitive, real-time dashboard that shows current referral data. Key performance metrics such as clicks, visits, bounce rate, and conversions would be available for creating a realistic view about the engagement with users. 
4. Conversion Tracking: Referrer Tracker V4 tracks conversions and connects these to specific referral sources. You can see all of the customer journey from source through to purchase, so you can better determine which channels are profitable. 
5. Customisable Reports: The module produces a detailed report based on several types of time frames, sources, campaigns, and customer actions. You can download reports for later review or to share with the rest of your team.
6. Google Analytics Integration: Referrer Tracker V4 can integrate with Google Analytics, giving you access to extra data layers and providing a more holistic view of your marketing performance.
7. Automatic Source Identification: Users, who prefer not much setup, will love to know that Referrer Tracker V4 automatically detects and classifies referral traffic using no URL customization. The usual sources are automatically collated, thus organising the data into such categories. 
8. IP and Bot Filtering: Referrer Tracker V4 can eliminate unwanted and humanless traffic, for instance, those coming from bot sites or internal IPs, which makes data more real with respect to customer activity. 
9. Affiliate Program Compatibility: You can use this module even when you're using the affiliate program since it has the capability to track sales arising from affiliate links and make remunerations to affiliates.
10. Multi-Store Support: This module tracks every separate store in your OpenCart setup, perfect for organisations having multiple brands or even regional sites.
