Inconsistent Data Collection and Tracking Challenges for a Restaurant Menu Website Using Piwik PRO

I am managing a restaurant menu website that relies heavily on Piwik PRO for analytics, user behavior tracking, and conversion measurement. The website includes multiple menu categories, promotional content, dynamic pricing, and seasonal offerings. Despite having Piwik PRO implemented, I am encountering inconsistent data collection across different pages and user interactions. Certain menu items, user clicks, or session events are recorded correctly in some sessions but completely missing in others. This inconsistency makes it extremely difficult to analyze user behavior, measure engagement, or optimize menu presentation for conversions. I am unsure whether these issues are caused by implementation errors, client-side tracking delays, or server-side API processing within Piwik PRO.

Another significant challenge is tracking dynamic content accurately. Many of the menu items are rendered dynamically via JavaScript or API calls, which sometimes prevents Piwik PRO from capturing relevant events, such as item clicks, add-to-cart actions, or category filters. Even when using custom event tracking, the data is occasionally delayed or missing entirely, resulting in incomplete analytics. I am looking for best practices on reliably tracking dynamically generated content on high-interaction pages without interfering with page performance or user experience.

Session consistency and user identification present additional difficulties. The website allows repeat visitors, loyalty members, and multi-device users, and accurate session tracking is critical to understanding user journeys. However, user sessions sometimes appear fragmented, and returning visitors are occasionally counted as new users. This not only skews engagement metrics but also complicates conversion and retention analysis. I would like guidance on how to configure Piwik PRO to properly recognize returning users, maintain session continuity, and integrate with authentication or CRM systems while preserving privacy compliance.

Form submissions and menu feedback collection also present issues. The website includes several interactive forms for customer feedback, order inquiries, and promotional sign-ups. While Piwik PRO is configured to capture form submissions as conversion events, some submissions are not logged, especially when users submit data from mobile devices or after long sessions. I suspect that asynchronous form handling, page caching, or JavaScript execution timing may be contributing to these missed events. Best practices for reliable form tracking, event binding, and testing across devices would be extremely helpful.

Integrating multi-location or multi-category analytics adds another layer of complexity. The website supports multiple restaurant locations, each with slightly different menu offerings and pricing. Capturing and segmenting analytics by location, category, or promotional event is critical for understanding performance at a granular level. However, setting up separate tracking segments and reports in Piwik PRO has been challenging, especially when dynamic content and personalized menus complicate event attribution. I am seeking guidance on structuring tracking hierarchies, event naming conventions, and custom dimensions to ensure meaningful and accurate reporting across multiple dimensions.

Finally, I am concerned about long-term data integrity and scalability. As the website continues to grow with more menu items, promotions, and interactive features, I want to ensure that Piwik PRO can handle high volumes of event data without impacting site performance or analytics reliability. Ensuring accurate real-time reporting, clean data pipelines, and maintainable tracking configurations is essential for supporting business decisions, marketing strategies, and operational improvements. Any insights from the Piwik PRO community on optimizing data collection, managing dynamic content, and maintaining long-term analytics integrity would be greatly appreciated. Sorry for long post!

Is there anyone who can guide me please?

Hi! Thanks for the detailed context - you’re touching several advanced areas at once (dynamic JS rendering, high-interaction tracking, session identity, forms, multi-location segmentation). When tracking appears “inconsistent,” it’s usually not random behavior in Piwik PRO, but a sign that some hits are not being sent (tag not firing, request cancelled on navigation, blocked by consent/ad blockers), or cookies/session identifiers are not available consistently across pages/devices.

Because your case involves both website behavior (SPA/API rendering, async forms, caching) and analytics design (event taxonomy + dimensions + user ID strategy), it’s hard to resolve safely in a forum thread. I strongly recommend involving your implementation agency/developer team for an end-to-end audit.
