I want an accurate picture of all the visitors landing on the website and converting. Unfortunately, the adblocker tools also block Google Analytics and Google Tag Manager, I am using the newer script
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'my id here');
How do I prevent this from getting blocked by ad blockers and other tools. THIS article only shows how to unblock the previous version of the script
You can proxy the analytics request through your own domain, and obfuscate the telltale keywords regex-based adblockers key off. I wrote a very detailed article on this topic. As for opt-out, they should get a GDPR banner, and if they decline, they can leave your site. Simple as that.
I'm not a lawyer however I think it goes against the Analytics TOS to try and circumvent a user's choice/ability to opt-out of GA tracking. The GA TOS states the following under the 7.Privacy section:
You must not circumvent any privacy features (e.g., an opt-out) that are part of the Service. You will comply with all applicable Google Analytics policies located at www.google.com/analytics/policies/ (or such other URL as Google may provide) as modified from time to time (the "Google Analytics Policies")
You can find a list of the GA TOS for all countries on the following page
