  1. Hi Jason, great tutorial. I have a question, on preview mode, i was able to see my tag is fired. But on live website, i am getting this error: An error occured while the tag was fired: net::ERR_NAME_NOT_RESOLVED, what seems to be the problem here?

  2. Hi Jason! Great video, thanks! I have a very beginner-level question for you. How do I find and remove all tracking codes from my website? And does that need to happen after I install the GTM code on my website? I'm finding myself a little confused as to when to delete these existing codes. Thanks again!

  3. Hi Jason, brilliant video thank you! I was originally trying to avoid tag manager because I thought it would be too hard, but you've proved me wrong.
    I have one question though: I've added the remarketing tag but tag assistant says "to validate please enter feed ID" – I could only find one answer online which said it was my google merchant ID (I have an e-commerce website with shopping campaigns set up) but that did not seem to fix it. Do you have any ideas as to what it's asking for?
    Is this a case of google asking me for the feed I'm using in my remarketing campaigns, but because I am currently not doing any remarketing there is simply nothing to add?
    Thanks once again.

  4. Hi! Thanks for all that valuable information! I have 2 question when it comes to Facebook pixel, I installed with Facebook plugin, and it works also for API, Catalog. Besides, All the data when I move it, does it affect what I already have in my pixel?

    I appreciate if you can respond. Thank you

  5. Thanks Jason. Great explanation, although it lost me at a couple of points as my website is not yet built out enough for the URL's required, and my WordPress site does not go to a different page (URL) when a contact form is submitted for example. I do know I can come back to review it, however. Question: If you have multiple businesses and websites what is the best way to structure Google Tag Manager and Google Ads Accounts?

  6. Hi Jason,

    I have a problem because I want to add a lead tag (google adds conversion, min 32) but I have a Ninja form plugin in my site. The thing is that when someone clicks the "send" button, the URL doesnt change. It only shows a confirmation message in the screen but URL stays the same

  7. Hey Jason,
    Amazing content – you have been a huge help!
    This might be a stupid question – I'm at the final part and you want me to set a conversion tag to customers that have purchased. For my business, I would obtain their email address. Is it still appropriate to set up a tag at the final payment page if so why and how will that data help the business?
