Is there any problem with installing the GTM and DTM in the same site? I searched and read about being careful with Data Layer, but I'd like to know if there's any conflict between the tools
Solved! Go to Solution.
It's typically not a good idea in general to have two tag managers deployed on the same site. Can I ask why you're trying to install both on the same site? If you are just testing both tag managers, could you use them on different sites or different sections of the same site?

I second the notion that having more than 1 TMS on a site is not generally a good idea. However if you are forced down this path there are a few things to make sure you are doing / not doing.
1) NEVER EVER EVER use one TMS to deploy another TMS. It's bad mojo.
2) The success rate of having code in one TMS try to grab variables that are being set/used in the other TMS will be quite low and it most likely not something any TMS vendor will support.
There might be other items but these are the 2 that stand out the most to me.
Hi Jantzen,
My question is just to confirm something. I don't intend to add two TMS in the same site but I need to see other opinions about this topic. DTM is not very popular in Brazil, so I thought I'd better ask.

Understood. Did you have other questions about DTM that we could help with? If not, could you mark one of the replies as the correct answer?

Hello! I have a similar question, and would like to fully understand key disadvantages of having both GTM and DTM on the same site. Site speed? Inconsistency in data? Any other reasons not to have both running at the same time? Would appreciate any references to official sources where this can be outlined. Thank you in advance!

Rudi pointed out a few of them above:
Is there a specific reason you want to deploy both on the same site? DTM is able to deploy any pixel/code you'd like. Almost all limitations of DTM are being addressed with Adobe's newest tag management offering Launch, by Adobe
Thank you Jantzen. Agreed with everything mentioned here. The main reason for deploying both is related to media tracking and Google Adwords integration. The client wants to continue using AdWords, and I've heard Adobe's integration with it isn't perfect...

Sounds like a great opportunity for someone to write a "perfect" extension in launch for the integration.
Launch is being built as an open platform where customers and third-party consultants will be able to build their own extension. This will allow for our experts within the community to build integrations with just about any pixel/tag out there. We will no longer be limited by having a single team being responsible for every integration and extension.
