Huge Analytics discrepancy when I turned off Analytics Module & Turned on GA via GTM
-
Hello,
I was running universal GA via a GA Drupal module. We setup Google Tag Manager and setup a GA tag to run through GTM. When we pushed the GTM container live our Real Time was at around 1900 and when we turned off the Drupal module the Real Time was reporting around 1100.
After 24 hours the sessions for that day were about 100k lower than what they usually are.
Any ideas Why the larger discrepancy? Any places that are obvious to look?
*I didn't setup the original Drupal GA module, nor do I know who did.
Thanks

Thanks, Dirk. I had the devs move the data layer above the GTM container snippet. The GA tag is still not firing on pages with a data layer and firing on pages without a data layer.
Obviously, it looks like there is an issue with the data layer -- I can't figure out what it is. I took a screen grab of the data layer in the source code.

Can only give you a theoretical answer - don't have that much experience with debugging the tag manager. From the "manual":
Data layer needs to be above the container snippet
Datalayer should be added above the container snippet. Variables pushed to the data layer after the container snippet will not be able to fire tags on page loads with a matching condition.
Variables pushed to the data layer after the container snippet will not be able to fire tags on page loads with a matching condition.
Move the datalayer to above the container snippetCheck also https://www.optimizesmart.com/google-tag-manager-data-layer-explained-like-never/ - it seems that you define your data layer after the position of the tag - so the tag cannot send the info from the data layer to Analytics. Check your source code & check where the data layer is defined. Probably it's ok on your category pages but not on the detail pages (compare both types to see the difference)
Hope this helps.

Hey Dirk,
I checked the debugger and on the pages where the tag isn't firing the console isn't even acknowledging GTM.
The Tag Assistant is showing this error on pages where the GA tag is not firing: 'data layer needs to be above the container snippet.' Do you think this could be the issue?
I work with a journal site, and I notice that on landing pages the GA tag mostly fires correctly, but on article pages the tag doesn't fire and I get the 'data layer' error from tag assistant. e.x: the tag fires on /news but not on /news/some-random-article-from-today
-
Apart from the Tag manager assistant - you could also check the debugger -https://chrome.google.com/webstore/detail/google-analytics-debugger/jnkmfdileelhofjcijamephohjechhna?hl=en-US - like Martijn mentioned there should be an error somewhere - did you check the messages in the console?
-
That is possible, the coding is a mess. How could I see if there were or were not JavaScript errors on the page? And if there were, how to pinpoint which are interfering with my GA tag firing?
Thanks, Martijn!
-
Are you sure that there are no JavaScript errors on the page?
-
I found a subdirectory that the GA tag is not firing on though the GTM container is present.
When I use Debug, I get this message:
No tags were evaluated because there was no Event in the selected Message
I have no idea as to why the tag is not firing.
-
Hmm yeah that seems right to me!
-
Thanks, Dirk. I'm going to follow your suggestions.
Martijn, the track type id is 'pageview' and is set to fire on 'all pages'. For my Tag Firing Options I have selected 'once per event.'
Does that seem to be right?
-
What Dirk is suggesting would be the first thing to do in my opinion as well. But the second one is what trigger are you using in Google Tag Manager. Are you targeting all pages in there or something else?
-
Run Screaming Frog - and check if the tag id is present on all pages. Apart from checking - you could also extract the code from the source to double check that the ID is correct; check here how you can do this
In Analytics reporting (Behavior > Site Content > Content Drill down) set the day after migration & compare it to the day before migration - check if there if the drop is generic (=all pages) or linked to a few sections. If the drop is higher in specific sections - go down to next level & do the same. Check the pages with the highest traffic loss using the Tag Assistant plugin for Chrome. It checks if the tag is properly implemented on these pages (https://chrome.google.com/webstore/detail/tag-assistant-by-google/kejbdjndbnbjgmefkgdddjlbokphdefk)
You can also use the Tag Assistant plugin on your main pages to see if it is sending data as you would expect.
Hope this helps.

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.

Analytics conversion tracking?
Hi One of our clients has a hotel chain currently which currently uses an online booking system which is from a third party. We are keen to set up conversion tracking to track the number of bookings made however are we able to do this if the URL destination is not on the clients website? Or will it be a case of just tracking the number of people who click the link to go to the third party payment site? Kind Regards

Google Analytics Goals are not recording
Hello! I've set up Goals within Google Analytics and they aren't registering. I'm wondering if someone can review what I've set up to see if I've entered something wrong. I'm trying to track enrollments. Here's the site info: Enroll URL: http://www.careplusdentalplans.com/individuals/enroll-careplus/ Upon completion, the user goes to a Thank You page and our CMS generates a trailing URL parameter. For example: http://www.careplusdentalplans.com/index.php/individuals/enroll-careplus-thank-you/#123456789 My Goal info in GA: Goal URL: /individuals/enroll-careplus-thank-you/
Reporting & Analytics | | SmileMoreSEO
Match Type: Head Match (to disregard trailing URL parameter)
Goal Funnel: Step 1: /individuals/enroll-careplus/ I'm curious if the problem lies in either: The URL: Notice how the URL adds /index.php/ on the thank you page. In that case, should I enter the full URL in the Goal instead of the truncated URL? The Funnel: Is it necessary to show the initial Enroll page or if I'll see that in the Flow Visualization regardless? Thanks in advance for helping me out. Erik0 -
Analytics oddity
This one has me a bit puzzled... I was just conducting a bit of routine analysis on a client's site, when I noticed avg. traffic doubled on one particular day. Now, this was easy to spot, since avg daily traffic for this site is 100 per day. The site also has approximately 100 pages of content. Here is the odd part... the spike was clearly attributed to Direct traffic and from a specific network in Palo Alto. The Bounce Rate was 100% and it appears that every page on the site was visited - very briefly. Any clues as to what may have triggered this? A competitor maybe? An unkown bot? I am looking forward to your thoughts.

Google Analytics should track users from iPhone App
Hi Mozzers, you say there are no dumb questions, here is one. We've build an iPhone App for our Website working-dog.eu. So users can read there new messages with ease when they are out of the office, read about breeds, ... do all the nice stuff they want. I don't think so, but is it possible to track these users with Google Analytics? When the come via App, the Analytics code will not run for them. But maybe it could start an AJAX request or something like this? But how should the code run, without a browser which can interprete JavaScript? So, in short: Is it possible to track users from iPhone App with Google Analytics? Kind regards Patrick
