Can tracking affect website speed or performance?

TLDR: Yes, client-side tags can slow load times, but server-side tagging and optimized scripts minimize the impact.

Bond of Tracking and Webpage Loading/Network Speed:

In modern world where internet plays a crucial role in commercial processes, tracking of websites became a key factor to acquire beneficial information about the website visitors and the overall performance of business in context of web presence. However, one of the major questions that website owners often have is if these tracking tools can impact on our site’s speed. Let’s start with this topic and let’s look at what is actually happening, simplified in a way that anyone can comprehend.

The short answer: Yes, but It's complicated.

In other words, tracking really can impact site speed and performance. However, the level and scope of such an impact is relativistic to one or many factors, and there are measure of mitigations. Let's break it down further.

How Tracking Affects Website Speed:

1. Additional Load Time: Each time you add a tracking script to your website it is like tying a little ballast on the legs of a runner. Maybe it does not sound like a lot in the beginning, but it starts to accumulate. Research also indicates that every tracking script can slow your page down by approximately 2.5%. That may not seem like much but think of if you have 10 or as much as 20 trackers!
2. Resource Consumption: Unlike scripts, tracking scripts require some computing power in order to execute. They exploit the resources of your visitors’ devices, which is not very friendly to the visitor when running on low end devices or slower internet connections.
3. The Snowball Effect: The overall effect becomes intensified with the higher quantity of trackers being used. And the number of trackers is even shocking: some sites load trackers in tens of numbers, which inevitably slows down the page’s loading time. For instance, news sites use on average 7 trackers which can result in loading more than 3 times slower with trackers than without.

But Don't Panic! There's Good News Too:

1. Asynchronous Loading: As is probably evident from some of the other examples in this article, lots of present day tracking solutions incorporate what is known as “asynchronous loading.” This means they are served separately from your main website content, which decreases the load time of your first few pages of content. However, always remember that theytoo consume resources once they begin to operate.
2. Optimization Techniques: There are ways to reduce the effects of trackers to some extent. For example, utilising tag management systems can assist you to load trackers more effectively and offer you ultimate control on when exactly the tags load.
3. Regular Audits: If you are actively analyzing your tracker usage and removing any and all unused ones, then your website can be lightening fast. It is as if your website needs a good spring cleaning When this happens, you call an expert to come and help you clean your house.

Finding the Right Balance: The important thing to understand is that while you need to capture as much data as possible and always have a fast and easy to use website itself. Here are some tips:

1. Prioritize Essential Trackers: Make sure that the tools, which you engage in for tracking, are those that provide useful data in the business.
2. Use Tag Management: Subscribe to a tag management tool to have a better deal with the trackers.
3. Regular Performance Checks: Check your website’s speed and performance frequently to identify the problems that happened.
4. Consider Alternatives: It will be useful to consider other less intrusive analytics solutions which might affect the performance less.

Conclusion: Indeed, using tracking tools does impact your website in terms of speed and other aspects but this influence can be controlled.
