This has gone full circle and honestly is quite irritating at this point.<p>People say that Google uses GA data for advertising, I say that this is not the case and then you just chose to ignore that. So I&#x27;m just gonna ask directly - can you show some evidence suggesting Google uses GA data for building advertising profiles or did you pull this opinion out of your ass?<p>Because as someone who analyses marketing and advertising data, I can tell you that I strongly believe they do not use GA data in this way. 1) They have no need to, they have better data; 2) This data is unreliable; 3) GA prohibits the use of personally identifiable information; and most important of all:<p>THE WEBMASTER CAN CHOSE TO NOT SHARE IT WITH THEM. If this webmaster went out of his way to tell google not to store IP information, I think it is pretty safe to assume that they did not opt-in to share the data with google AT ALL.<p>Apart from these technical reasons, using GA data in the way you think they do opens a regulatory risk of EPIC proportions.<p>But if you have some evidence to suggest that they do use it for &quot;advertising profiles&quot;, please do share it. But if you can&#x27;t and you formed this opinion because you are prejudiced, I would like to see you admitting it.
