Two GTM tags
-
Hi guys,
I need some help on the following:
My client has different websites worldwide all with country extensions and on overall .com domain. These websites (and GTM accounts) are all managed by local agencies. We would like to implement a cross domain tracking GA account in order to see some overall trends and numbers. We don't want to implement our codes in the existing containers as they are in many cases managed by local agencies. Is it really negative to implement two GTM containers on one website?
Any other ideas?
Thanks,

No - I think you'll want 2 different UA codes AND 2 different data layers. You'll also want to test the hell out of that implementation and make sure it's working well.
Sorry for the confusion.

Thank you Kane! Very helpful!
So what you are saying is that it is completely safe when we are using two different GA codes? Or should I still rename the data layer in this case?

According to a few other sources online, having two GMT containers on the page may cause triggers to fire twice. It appears the fix is to rename your data layers on at least one of those containers, but other pages recommend only using one. So, your cross site container probably needs some more customization, and then close monitoring to make sure stuff is working correctly.

Additionally it's worth mentioning that if both GTM tags each have GA tags in them, that is fine if the UA codes are different - full details can be found here: https://support.google.com/analytics/answer/1032400?hl=en. What you don't want is two GA tags with the same UA code.
Is it safe to say that your client has admin access to all of these random GTM containers? If it were me, I'd prefer to own those containers and give each agency access to the appropriate one.

Thank you Martijn, very valuable! Any other opinions?

Hi Sander,
I'd say no, it's not really bad. It will have a small impact on the load time of your site probably but besides that it will enable you to do most of the things via a tag manager which will provide you with more flexibility.

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.

GTM: Transaction value without tax as variable
Hi Mozzers, I'm trying to create a GTM variable for transaction value without tax. There is no datalayer field for this at the moment. e.g. I only have these fields in the datalayer: Revenue (€19.99) Tax (€3.47) Price (€19.99) No field with the price without tax. Is there a way to create a variable? Is it possible to work with a specific function? Or is it standard to implement an extra field in the datalayer? Many thanks,

Title Tag Capitalization Impact on SERP Rankings and Click Through Rates
My company made a branding decision to use lowercase for all of our title tags. This, of course, means that our titles on SERPs are all lower case. Overwhelmingly, it seems that websites use title case. This makes me wonder if we're shooting ourselves in the foot. Does using lower case titles negatively impact our rankings and/or click through rates? Is there any data out there suggesting that title case has a better click through rate than lower case? Thanks for reading!

Why Webmasters Tools verification meta tags change??
Why do these keep changing for sites that I have verfied over and over and over and over? About a month goes by and the meta code has changed and the site is unverified again. Seems like a trick to force you into logging into Webmaster Tools all the time. What gives???

Google News traffic spike mystery; referring URLs all blank, Omniture tags didn't fire.
Our content is occasionally featured in Google News. We recently have had two episodes where this happened, but (a) nearly all the referring URLs were blank, and (b) our backend logs show 3-4x more requests for the article in question than Omniture does. In other words, hundreds of thousands of visitors requested a URL from our site (as proven by the traffic logs), but don't seem to have come from Google News (because HTTP_REFERER was blank), and didn't execute the onpage javascript tag to notify Omniture of the pageview. Perhaps this has nothing to do with Google News, but it is too strong a coincidence that the two times we were on there recently, the same thing happened: big backend traffic spike that is not seen by Omniture. It is as if Google News causes browsers to pre-fetch our article without executing the javascript on the page. And without sending a referring URL. Has anyone else seen anything like this before? Stats from the recent episode:
Reporting & Analytics | | mcglynn
- 835,000 HTTP requests for the article URL (logged by our servers) - these requests came from 280,000 distinct IP addresses (70% US) - the #1 referring URL is blank. This accounts for 99.4% of requests. Which, in itself, is hard to believe. These people had to come from somewhere. I believe browsers don't pass HTTP_REFERER when you click from an SSL page to a non-SSL page, but I think Google News doesn't bounce users to SSL by default.That said, we do see other content pages with 70-90% blank referring URLs. Rarely 99+% though.0
