Analyzing the increase in the number of 3rd parties on Websites


#1

There is an increase in the number of 3rd party pixels on websites. Is there a way to analyze the % increase in the number of 3rd party pixels being fired on the websites?

Hmm, that’s both a statement and a question… As in, you believe there is an increase and you want to verify via HTTP Archive? A couple of things to consider:

  • There is no reliable way to detect “3rd party”. We’ve had a few discussions on this in the past, check past threads on various approaches and limitations - e.g. What is the distribution of 1st party vs 3rd party resources?.
  • There is no direct way to detect a “pixel”… I guess you could look at the response size and use that as a proxy.
