Before GA4 was a required thing, I'd been apart of switching website vendors multiple times. It really wasn't that big of a deal to have conversions under different names; they all pretty much tracked the same things across vendors.
I never ran into an update that broke a gtag script, but I suppose it could happen, but it is highly unlikely due to the fact that it latches onto things via classes or IDs. Example:
[CODE=javascript]var clickToCallLinks = document.querySelectorAll('.phone-number');
if (clickToCallLinks) {
clickToCallLinks.forEach(function(link) {
link.addEventListener('click', function() {
gtag('event', 'click_to_call');
});
});
}[/CODE]
I am in a group with multiple OEM website providers and have never had this issue. If there isn't someone looking at their analytics often, you have a much bigger problem than conversion tracking.
Back before GA4, if you reached out to any vendor, they would have the team or manpower to get any conversion made that you could want. It would be a simple phone call or email asking for it.
Unicorn or not, it's a situation I've seen firsthand where they wanted reporting (all be it before GA4) setup and couldn't afford to pay someone to set it up. I ended up doing it for them for a discount on a vehicle before I even worked in the automotive world.
Will look into it, thanks.
