Revisiting Log File Analysis versus Page tagging
It’s 2025, and page tagging has solidified its place as the industry standard in web analytics. A decade ago, many companies relied on both log file analysis and page tagging, but now, the trend is clear—page tagging is taking the lead. But why has this shift occurred? Let’s break it down.
Round 1: Ease of Implementation
The primary advantage of log file analysis is that web servers already produce raw log files. This means the data is readily available without the need for additional setup. But to collect data via page tagging, you need to modify the website, right? The argument is that it’s simple if your site is small, but for larger sites, implementing tags requires resources.
But does it really? The truth is, many modern applications—like blogs, CRM tools, and e-commerce platforms—come pre-equipped with tagging solutions. Integrating tags is no longer a big task, making page tagging the obvious choice for most companies.

Round 2: Vendor Lock-In
Some argue that page tagging solutions lead to vendor lock-in. However, with the ease of integrating multiple tags, it’s no longer a real issue. Today, many companies run several tags in parallel without significant difficulties. The supposed “vendor lock-in” is more of an illusion, especially when the flexibility to use different tools is readily available.

Round 3: Reliability of Data Collection
Log file analysis is often praised for its reliability. The server logs every transaction it processes, ensuring no data is missed. In contrast, page tagging might miss some transactions, right? While this was once true, it’s much less of an issue today. Tags are placed properly by third-party applications, and developers now pay close attention to analytics needs. Moreover, accounting systems are used to cross-check analytics data, ensuring that any discrepancies are identified and fixed.
Round 3 is a Tie.
Round 4: Challenges with Static or Dynamic Content
Another argument for log file analysis is that it can handle static content like PDFs or dynamic pages generated by applications—where adding tags is impractical. However, page tagging has evolved to accommodate these issues. With event tracking and other advanced tools integrated into analytics platforms, even static and dynamic elements can be tracked effectively, eliminating the need for manual tag implementation.

Conclusion: The Clear Winner
The competition is over. Page tagging has become the defacto standard in web analytics, offering ease of implementation, flexibility, and a wide range of features. It’s now driving down the costs of data collection and analysis. As new tools and features continue to roll out, page tagging’s dominance will likely continue, leaving log file analysis as a more niche solution.
