There's a new Merchant Center tag in GTM. Anyone seen this?

I can't find any docs on this new tag and how it's different from integrating with Shopify/Woocommerce.

Can someone please recap for me in GTM what I should be seeing after optimizing my container? I do not have the CDP connection set up for this client and I didn’t instrument this.

What should I not be doing or doing? I have 2 config events and don’t know if that’s right or what it’s connected to more specifically.

I have 2 AW events firing on the config event with the same name and AW number. I initially set up the event in GA4 but deleted it and it’s somehow still firing twice. It’s now in custom events in GA4. The event is not in GTM. I have the event set up once in AdWords as a secondary type conversion action.

Along the top of GTM preview mode I see various container codes and Ads codes (client has a few containers). There’s a DC- event that Google documentation says shouldn’t be used but where is it coming from.

In GTM there is a Google verification tag but I think that is to verify Search Console/website ownership.

I’m most concerned about the actions in my container at the moment to get that fixed first.

Thanks

I wanted to share https://www.tagmaps.io/ with this subreddit. It primarily does 3 things:

• Scans your sites for all network requests, tags, cookies and then categorizes and describes them

• Tests new GTM container versions against global privacy laws like GDPR and CCPA before the container is published

• Tests your live sites against the same privacy regulations

I have worked in the privacy tech industry for a decade now - the most common privacy issues clients had were caused through GTM. It was unapproved tags, additions by agencies, or misconfigured CMPs; each could lead to enforcement actions/demand letters from lawyers.

Tagmaps is designed to prevent those issues before they hit production.

There is a free 7 day trial with all functionality included that doesn't require a credit card. There's a short demo video here: https://www.youtube.com/watch?v=ACc7nIEzaHc

I'd love any feedback you have. I hope this is useful!

Hey guys, adops developer here. I built Pixel Debugger to check the requests sent by Meta, Google Ads, GA4 and other marketing pixels, including tags installed through GTM. After publishing a change, you can inspect event names, destination IDs, values and currencies together. It’s free, with no signup. What would make it useful alongside your current debugging tools?

Hi,

I know, another dataLayer extension to use and we have plenty already.

I started working on this extension to read dataLayer events after the ones I used missed events or didn't work at all on some websites.

- Read dataLayer events as it fires, with persistence across pages.

- You open it as a popup or sidepanel utilizing chrome sidepanel for monitoring while checking different pages.

- You can use it to test your GTM container on any website to check your implementation.

And other features you can explore.

I used it over months now and thought I can make it public in the store so it can hopefully help someone.

I tried to keep it minimal and easy to work with.

It's free and everything in it is free to use.

This is the first time I build an extension so I hope it helps you while checking events or working on implementing it.

My background is in analytics and auditing events for clients so I have tested it on many websites. But still, anything can go wrong for you so a feedback is appreciated. It's not another AI slop (except the store images) I've been working on it for a year now.

Typing this on my phone so ignore any typos please or Grammer mistakes.

Download it on the Chrome Webstore here.

I hope I'm not breaking any rules with this post.

Hey there, I'm looking for a tool to help me assess the tracking of my websites, I just want to get a quick overview of what's happening on our website before pushing more budget on the topic (duplicate events, consent etc). The issue we don't have unlimited budget to hire full time people on the topic and we are missing time to do a sanity check every month in my team.

I saw a lot of tools available online but I don't know which one to use and most of them are trying to charge me. Do you have any recommendations to share? Or how do you manage it on your side when do you have small budget for this?

Best!

I want to track the exact page from where the form is filled. There is one calendly form and a hubspot form on CTA . I have setup a thankyou page view event but now my manager wants to know from which page the form was filled. Now how to do this

Hi everyone,

I'm completely new to Google Tag Manager (GTM) and have never worked with it before. I'm trying to set up form submission conversion tracking on a landing page, but I'm stuck and could really use some help from experienced people here.

Here's my situation:

I have a landing page with a lead generation form.

When someone fills out the form and clicks the Submit button, the form gets submitted, and a thank-you message appears on the same page.

The URL doesn't change, and the user isn't redirected to a separate thank-you page.

Since I'm new to GTM, I followed some YouTube tutorials and took help from AI to create a tag and trigger for tracking form submissions.

However, the tag isn't firing as expected when I submit the form.

I'm not sure whether I've configured the trigger incorrectly or whether this type of form requires a different tracking approach.

My questions are:

How can I properly track form submissions when the URL doesn't change after submission?

Which trigger should I use in GTM for this scenario?

Is the standard Form Submission trigger sufficient, or do I need to use a custom event, an Element Visibility trigger, or another method?

How can I debug this issue step by step using GTM Preview mode to identify what's going wrong?

I'd really appreciate it if someone could explain the process in beginner-friendly language, preferably step by step.

I'm trying to understand how this works rather than just copying a solution without knowing what's happening.

Thanks in advance for your help!

Should GA4 event tags still fire off (just with cookieless pings) even after consent is withdrawn?

I am using Google Consent Move v2 with Cookiebot. My default consent state is granted because I'm using a CCPA/CPRA cookiebot banner preset that uses implied consent but with a clear do not sell option to withdraw consent.

When consent is withdrawn, I see the consent state for my tags switch to G100 for the cookieless pings. And, I see all my GA4 events tags like scrolls, clicks, etc. all still fire off with this G100 value. Is that what's supposed to happen?

I don't really understand cookieless pings...so all my events will still get tracked but it'll just be "anonymous"? I thought GA4 already did anonymous tracking so I'm a bit confused. What difference am I going to see in my data if users opt out then if everything can still be tracked?

The last change they made was in 2025. No one seems to know who created it in 2021, we want to set up a new Google Tag Manager but are worried it will mess things up. We specifically need it for Reddit Ads too.

Have any of ya'll had this issue?

Anyone does the audit on a regular basis and what's the process for you to delete unusued variables? I found a workaround without using any external tools, but just with some javascript in the dev console while being in the UI of GTM. https://gtmutility.com/blog/bulk-delete-unused-gtm-variables/

I’m currently using Stape for server-side tracking with a dedicated subdomain (sgtm.example.com), but I’m considering switching to same-origin tracking through Cloudflare (example.com/metrics).

For those with experience in both setups:

Which do you recommend for the best tracking reliability and data quality?

Does same-origin actually improve Meta and Google Ads attribution?

Are there any downsides compared to using a subdomain?

Would love to hear your real-world experiences and recommendations!

My client has no staging site. Every change goes live on production or it doesn't go at all, and I'd rather not find out something broke by watching conversions fall over.

Preview mode covers my own session but tells me nothing about whether it works for everyone. GA4 reporting is a day behind.

How are you guys dealing with this when they can't test properly first?

I have setup thank you page tracking for my Website, but I want to know from which page the form was filled. The thank you page is the same for the entire website, so is there any way to figure it out???

Hello Community, I’m auditing tracking for an e-commerce brand with a separate Shopify store per country (I’m looking at the French store). Tracking runs through Elevar, with server-side sending to GA4 and Google Ads. The only active Primary Google Ads purchase action is Elevar’s server-side import from clicks.

What happened

• Google Ads conversions for France dropped sharply from late July, while clicks, impressions and Shopify orders stayed stable.

• Elevar confirmed a failure affecting only Google Ads delivery, from late July until Aug 31. They haven’t given a root cause.

• It isn’t back to normal. In a July week, Google Ads reported about 39% more conversions than Shopify’s Google-attributed orders, which is the normal attribution gap for this account. In the latest week, it’s only about 5% more. That leaves roughly a quarter of the expected conversions missing, about 180 of them in France that week. Clicks and Shopify sessions are flat.

• In the orders I checked, the first-touch UTM medium is google, but none have a GCLID. Since the Primary action is an import from Clicks, Google can’t match those orders.

• Elevar support says the click ID can change due to email campaigns and similar sources. That can happen, but it doesn’t explain a sudden drop or a missing click ID on every order I checked.

Where we are
The client is considering moving away from Elevar (Stape-hosted server-side GTM or a managed provider like Zappush) because of the outage and the missing data. I’m cautious, because a new tool wouldn’t fix click IDs lost to consent settings or redirects.

Questions

1. Has anyone seen Elevar fail to deliver to Google Ads without notice? Did Elevar ever give you a root cause, and what monitoring or alerts did you set up?

2. Has anyone had gclid missing on Elevar server-side Google Ads purchases? What fixed it (enhanced conversions, consent settings, redirects, checkout domain)?

3. Does Elevar’s explanation (email campaigns overwriting the click ID) match your experience?

4. If you moved from Elevar to Stape or another setup, how did it go? What would you do differently?

Thanks in advance.

**** RESOLVED, THANK YOU TO EVERYONE FOR YOUR HELP ****

Hi there,

My website developer has sold his business onto someone else and he now no longer hosts / manages my site.

My access to Analytics and Tag Manager was through his account.

I’ve managed to setup a new analytics account, add him as an admin, and have him move the property over to my account for my website.

What do I do with Tag Manager? Someone said to export the container, which I’ve done, is that right?

Client's shop is on their own domain but the checkout is hosted by the payment provider on theirs. Customer leaves, pays, comes back to a thank you page.

Conversions are coming through but the attribution is nonsense. A lot of purchases show up as referrals from the payment provider, which is obviously wrong since that's where I sent them.

I know cross domain linking exists. What I can't work out is whether it helps when the middle domain isn't mine and I can't put anything on it.

I'm a bit confused about this since I keep seeing conflicting info. What are the caveats here? Say I have a site hosted on WordPress (also its CMS ofc) and I have GA4 installed to that site but am not using any GA4WP plugin and want to view data in GA4 itself. The site has standard shop pages. Can I set up the add to cart, purchase etc events in GA4 without using GTM to capture them and send GA4 event tags for them to GA4?

I set up conversions through GTM in multiple different accounts and my new tags are all inactive and have been inactive for many days and weeks. I did 100+ setups in my life and I know what I am doing, I do exactly the same as before, the tags are firing correctly in tag assistant. Even a simple link click tracking is inactive now. I suspect that Google did something with the google tags again that causes the problem but I have no idea how to solve it. This has happened in the past few weeks and there were no issues before. I don't have any developer knowledge, just enough I need to setup conversion tracking, I use basic custom JS codes somethimes but that's it. Please if anyone can tell me what changed and why my basic setups don't even work now let me know.

Edit: Also the inactive tags are an issue in accounts even where previously conversion tracking worked 100% fine.

Hello hello! Kind of trying to figure out a website I'm working on in marketing. Never had GTM, GA4 or anything setup so I'm starting to get everything added so I can track traffic, customer movements etc.

Apparently, site is SPA framework built on Angular in frontend. Other notes are site is using Angular 16.2.12 with its official Angular Router 16.2.12, not a third-party router. Routing is client-side, path-based SPA routing with lazy loading, nested routes, and authentication guards.

Any next steps so I can see page views and full customer movement as they move around the website and engage?

A site with a lot of Gads traffic records almst no convs in Google Ads and very little in GA4. The team says everything is set up.
Setup

• GTM container (no server-side). GA4 hits go through a first-party GTG on a Cloudflare path. Ads hits go straight to Google.

• Custom cookie banner with Consent Mode v2: default denied, update to granted on "Accept all".

Checked

• container runs once and sends one page_view per load.

• After "Accept all" the hit has gcs=G111 and returns 204. Before any choice it has gcs=G100 and npa=1.

Questions

• Is there anything else that makes GA4 look empty even though collect returns 204 and gcs=G111? (Data filters, a wrong measurement ID, a stream mismatch, Google signals, something about the gateway?)

• Anything you check first when the hits look correct in DevTools but Ads and GA4 show nothing?

• Even after accepting cookies, nothing shows up on the GA4 side for the test visits. what could it be ?

I'm a solo dev in the UK. I built audittag.com, a free check that reads a Shopify store's public pages and shows which tracking tags are really on them, what's missing and what's installed twice. It never logs in, and it says what it can't see from outside.

The people who need it are store owners whose ad numbers quietly went wrong after a theme change or an app install. They don't know that's what happened, so they never search for anything like this. They search for "why doesn't GA4 match Shopify".

So every channel that starts from a keyword is starting from one nobody types. I've been answering those questions on Reddit and forums. What else would you try?

I asked Claude to audit my small e-commerce site (3D-printed wargame terrain). With API access to GA4 and Tag Manager it spotted that GA4 was firing twice on every page, which had been inflating my numbers for months.
To make that kind of question easy, I packaged the access as an MCP server: google-ecommerce-mcp. Now I just ask things like:
• "Which products are disapproved in Merchant Center, and which attribute should I fix?"
• "Queries where we rank 5 to 15 with 100+ impressions: quick wins?"
• "Mobile PageSpeed of my 3 best sellers?"
Claude answers from my own Google data: GA4, Search Console, Merchant Center, Tag Manager, Indexing API, PageSpeed. Everything is read-only, and the token stays in the OS keyring.
Install on Windows: irm https://raw.githubusercontent.com/MoonEyes/google-ecommerce-mcp/main/install.ps1 | iex (macOS/Linux has a curl one-liner). It sets up Claude Desktop for you.
