How many users completely block Google Analytics cookies ?
-
Hello everyone!
In your experience, how many of your visitors' browsers completely block cookies including those of Google Analytics ?
-
Anytime. I'm glad you asked it because I don't think many people realize how high these numbers may be (I know I didn't have a clue).
-
Thank you for your answer Kevin, and especially for the numbers ;).

See below from Azigo:
This post is a place to keep track of the sources of this info. So far I’ve only found a few numbers. Must keep digging.
- 30% of users delete cookies according comments by Jules Polenetsky on a panel at the W3C Workshop on Web Tracking and Privacy
- **40% **of users delete or block according to OpenTracker.net
- 36+% of Australian Internet users delete their third-party cookies in a month according to comScore report (2011)
- 76% of Safari users block third party cookies according to Gibson Research. Note: This is super-high because Safari is the only browser that blocks third-party cookies by default

Interesting question. I can't run the experiment now but it would be interesting if people could check their server logs to see how many people viewed the homepage, and compare that for the same period on Google Analytics and post the percentage of people not tracked in Analytics here.
That would give us a pretty healthy insight into it. I'll try to find some time to run it on a couple of our sites later this week.

If website users don't accept GDPR cookie consent, does that prevent GA-GTM from tracking pageviews and any traffic from that user that would cause significant traffic decreases?
I've been doing a lot research on GDPR impact and implementation with GTM-GA for clients, but it's been 12 months since GDPR has gone live I haven't found anything on how GA traffic has been impacted if users don't accept cookie consent. However, I'm personally seeing GA accounts taking huge losses in traffic since implementing GDPR cookie solutions (because GTM/GA tags aren't firing until cookies are accepted). Is it common for websites to see significant decreases in traffic due to too many users not accepting cookie consent? Are there alternative solutions to avoid traffic loss like that and still maintain GDPR compliance? It seems to me that the industry underestimated how many people won't accept cookie consent. Most of the documentation and articles around GDPR's start (May 2018) didn't foresee or cover that aspect properly, everything seems to be technically focused with the assumption that if implemented properly most people would accept cookie consent, but I'm personally not seeing that trend and it's destroying GA data (lost traffic, minimal source attribution, inaccurate behavior data, etc). Thanks.

Why is Indeed.com traffic appearing as organic in Google Analytics?
A large number of sessions in my client's Google Analytics account appear to come from medium: organic and source:Indeed. Since I'm focused on SEO for this project, I'd prefer that Indeed be treated as referral traffic. Any ideas for fixing this issue? Also, and I'm sure the answer is no, is there a way to fix the past data in Google Analytics that has already reported Indeed as an organic medium?

Would updating Meta Titles affect Google analytics tracking?
Hi All, I need a little bit of help. We need to optimize our blog's articles Meta titles for SEO which all exceed 100 characters. I was told that if we change the titles, google analytics would split the tracking pages and count the data as 2 pages (old title and new title). Has any of you have this experience before and if so, is there a way to avoid google analytics counting this as two pages? Thanks in advance!

How can I use Google Analytics to detect users viewing my website on a TV?
I want to see in Google Analytics whether or not people are viewing my website on a TV, such as with a smart TV or other device connected to their TV. These are the only ways to do this that I have found so far: Operating system: Google TV, Nintendo Wii, Playstation 3, Xbox Browser: Nintendo Browser, Playstation 3 Are there other data points that I can reliably use to segment these users?

Referral Traffic vs. Campaign Traffic in Google Analytics
I have two sites: a blog and an ecommerce site. The blog funnels people to the ecommerce site. In Analytics I'm seeing declines in referral traffic from the blog to the ecommerce site. During the same time I'm seeing an increase in campaign traffic to the ecommerce site, with most campaign traffic coming from the blog. I believe the increase in campaign traffic is largely a result of simply having installed more tracking links. This leads me to believe that the declines I'm seeing in referral traffic is simply a result of the increase in campaign traffic. In other words, what was once counted and reported as being referral traffic is now being counted and reported as campaign traffic. So my question is this: In Google Analytics is campaign traffic ALSO reported as referral traffic, or is campaign traffic reported separately and not duplicated in referral traffic reports? I'll provide a concrete example to make this more clear in case it isn't: Say site X sends 1000 visits each month to site Y. Say 50 of those visits come from a single link on X. If that link is changed so that campaign Z data info added (via the Google URL Builder), would you expect to then see 950 referral visits each month from site X to site Y plus 50 campaign visits to site Y via new campaign Z, or would you continue to see 1000 referral visits plus the new 50 campaign visits? Many thanks in advance to anyone that can shed some light on this.

Totally Remove "localhost" entries from Google Analytics
Hello All, In Google Analytics I see a bunch of traffic coming from "localhost:4444 / referral". I had tried once before to create a filter to exclude this traffic source, but obviously I did it wrong since it's still showing up. Here is the filter I have currently: Filter Name: Exclude localhost
Reporting & Analytics | | Robert-B
Filter Type: Custom filter > Exclude
Filter Field: Referral
Filter Pattern: .localhost:4444.
Case Sensitive: No Can anyone see what I'm doing wrong and give me a push in the right direction? Thanks in advance!0 -
Google Analytics: how many visits from country Google domains?
Hello, I manage a site with visitors from many different countries. With Google Analytics, it is normal to see the number of visitors from each search engine. However, I would like to identify the number of visitors from each Google-search contry domain. How many visitors from Google.com? How many from Google.co.uk. And from Google.co.zm? And so on. Anybody knows if this is possible and if yes, how can it be done? Thank you in advance, Dario
