## **The Dawn of Third-Party Utilities**

In the realm of marketing automation and analytics, third-party utilities such as [Google Analytics](https://analytics.google.com/analytics/web/) and [Facebook Pixel](https://www.facebook.com/business/tools/meta-pixel) have secured a substantial foothold. These tools employ 'tags', or code fragments, embedded within each webpage. Especially prevalent on traditional server-rendered pages, these tags facilitate a range of tracking and monitoring functions. 

However, as technology advanced, managing the escalating volume of tags on web pages became a significant challenge. This situation was particularly evident around 2010 when tech teams started wrestling with the bottleneck created by multiplying tags. This situation led to the advent of [Tag Management Systems](https://en.wikipedia.org/wiki/Tag_management_system) (TMS), which empowered marketing teams to independently inject tags, scripts, and more into their web pages, thereby promoting efficiency and agility.

Stepping into the limelight was [Segment](https://segment.com/), a venture backed by Y Combinator, which caused a seismic shift in the industry by creating [Analytics JS](https://github.com/segmentio/analytics.js/), a unified API consolidating event collection procedures from esteemed analytics tools like JTrack, [Facebook Track](https://developers.facebook.com/docs/meta-pixel/implementation/conversion-tracking/), and [Mixpanel Track](https://developer.mixpanel.com/reference/track-event). This innovation marked the advent of [Customer Data Platforms](https://segment.com/resources/cdp/) (CDPs), the subsequent phase in tag management software evolution. CDPs allowed organizations to derive actionable intelligence from their data.

## **Zaraz: The Groundbreaking Server-Side Tag Manager**

[Zaraz](https://www.cloudflare.com/products/zaraz/) is a server-side tag manager, running on the edge, that allows users to manage their tags and track user data in real-time. Another [Y Combinator](https://www.ycombinator.com/) [success](https://www.ycombinator.com/companies/zaraz), it was acquired by [Cloudflare](https://www.cloudflare.com/), an internet company that provides CDN, cybersecurity, and DDoS mitigation services, and is now part of Cloudflare's suite of products. Zaraz offers a resilient, adaptable TMS that features the developer experience of CDPs and aligns with [Data Protection Authorities](https://commission.europa.eu/law/law-topic/data-protection/reform/what-are-data-protection-authorities-dpas_en) (DPAs). This tool provides a streamlined tag management process and can integrate with any third party tools without significantly affecting page speed. Zaraz sets itself apart with its state-of-the-art computing capabilities. It blends the best features of TMS and CDP, offering users the ease of a dashboard and a unified API for an elevated [Developer Experience](https://www.getclockwise.com/blog/what-is-developer-experience) (DX).

Zaraz sets itself apart with its state-of-the-art computing capabilities on top of providing a streamlined tag management process. Zaraz allows you to control what the scripts you insert on your page do, ensuring they don't have access to anything they aren't authorized to see. This way, even if a third-party script provider is compromised, it won't result in a security incident. 

A standout feature of Zaraz is its integration with [Cloudflare's Workers Platform](https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/), offering a Data Localization Suite that aids clients in maintaining GDPR compliance. This feature enables clients to choose specific regions to run their software and ensures no superfluous data logging occurs.

Key aspects that set Zaraz apart:

- It capitalizes on the [Cloudflare network](https://www.cloudflare.com/network/), operating as closely to the user as possible.
- Cloudfare customers enjoy a substantial advantage.
    - Utilizes [HTML Rewriter](https://developers.cloudflare.com/workers/runtime-apis/html-rewriter/) to auto-integrate Zaraz.
    - Operates on its own domain as a first-party tool.
    - Utilizing workers allows it to offload client-side evaluations.

## **Third-Party Tools Statistics: A Numbers Game**

[An intriguing statistic](https://almanac.httparchive.org/en/2021/third-parties?ref=blog.cloudflare.com#fig-4) shows that 94% of global mobile pages host at least one third-party utility. Larger websites average around 43 tools. This heavy reliance on third-party tools can cause significant performance lags, particularly on mobile devices. Considering the substantial influence of page speed on SEO ranking and conversion rates, internet companies are now prioritizing [Core Web Vitals](https://web.dev/learn-core-web-vitals/), especially those focusing on consumers like e-commerce, publishers, and direct-to-consumer websites.

Data privacy concerns are also escalating, with DPAs restricting the use of third-party tools due to privacy issues associated with sharing users' IP addresses. This trend is increasingly apparent not only in Europe but also in the US and Asia. Moreover, the future of advertising is transitioning towards a model devoid of third-party cookies. As browsers prohibit the use of third-party cookies, companies dependent on advertising are moving towards technologies that support this new model.

Acknowledging user concerns about the potential influence of third-party tools on their websites, the Zaraz team developed a revolutionary solution - the first-ever TMS/CDP that loads tools at the edge, away from the user's browser. This inventive, cloud-focused strategy offers numerous benefits. By relocating the tools to the cloud, websites can sustain peak performance without being overloaded by the plethora of third-party tools. Furthermore, this method ensures a higher degree of control over data transmission, mitigating potential GDPR compliance issues related to transmitting users' personal data abroad.

As we gaze into the future of TMS and CDP technologies, the evolution of these tools points towards continuous enhancements in data management and analytics. With Zaraz at the forefront of this evolution, businesses can anticipate amplified control, flexibility, and performance in managing their website's tags and customer data.

## **Conclusion**

The trajectory of web analytics and tag management systems underscores the dynamic nature of the digital universe. From the emergence of third-party tools, to the ascendance of CDPs, and the unveiling of cloud-centric TMS like Zaraz, we are on an exhilarating path of innovation and adaptation. This journey is fueled by an unwavering dedication to efficiency, performance, and data privacy. These elements are vital for SEO experts striving to optimize their clients' digital footprint. As Zaraz continues to revolutionize the way users manage their tags, it emphasizes the importance of innovation and adaptation in the swiftly changing landscape of web analytics.
