The best video that I've seen on the subject.

Hi Julius. I assume, it is best to create a fresh property dedicated for cross-domain setup before implementing. What do we do with existing GA4 properties for site A and B.and will those cookies conflict the crossdomain setup=?

[marissading]

Under the same property means adding the second website as another data stream?

[tudordaniel]

Great job, as usual. But whay if we want to report those domains separately in GA4, like we currently do with Views in UA?

If i need to track events in similar subdomains under 1one GTM container ? I can use same 1one GA4 property setting ?

Hi Julius. Thanks for the video. Quick one -- Before watching your video, i hadn't setup cross domain tracking, hence on GA4 events were recorded as Referral rather than the main source of conversion. However, i have fix this. Will the historically data recorded as "referral" be changed to the correct source now that i have fixed the issue?

Hi Julius, I have two seperate websites: One is built on Squarespace and the Other is built on CHIME (real estate IDX site)... I do use a vanity URL for the CHIME site, that is a sub domain URL from my primary site... but I believe since it's just a vanity URL that my CHIME site and Squarespace site are seperate.... would you consider them seperate domains where I should set-up cross domain tracking?

Hi Julius, great video. Do you maybe have a example of cross domain tracking set when an redirect happens? For example an URL gets built in PHP. Thank you

Will this work with my website + third-party appointment page (Appointmentcore)? The appointment booking page I have does have an option to put Google Ads tracking ID

[spicyboi]

Thank you! Can I do this cross domain tracking even if i have cloaked url between my 2 domains?

[emotionaleatingcoach]

👉What about a SUB-Domain with a different C-Name? For example, I have my main site and then a subdomain attached to Clickfunnels. Would that still track if I include the main GA4 code on the pages?

Hi Julius, I have got 5 different domains where user can go from any domain to other. Currently I have got GA4 property separately setup for each with ecommerce tracking on each that implies each has got different measurement ids. I want to setup cross domain on each for remain 4 sites. How I can do that?

[JuanAlbertoSanchoMelchor]

Hi, ​ I need to disable Cross-domaing tracking instead. No one cross domain is configured in GA4 but url's are always shown with gl_ parameter. Any suggestion? Thanks!

[idaho.idahopotatoesaintthe]

Thank you for the video! 2 Questions: 1) do the two domains only share the 1 tracking code/measurement id? 2) can you ross domain track from GAUniversal and GA4?

[AliHussain-gqom]

Thanks Julius! we have 2 domain and same product. one domain is used for paid search only. could this method help us have one ga that shows cross channel journeys in mcf repprts?
i mean when user enter the paid domain and later come back to main domain via organic search we can see its unified journey in our reports.

[tejastank]

[bigk]

Hey mate, I have 30 different computer repair websites - how could i make it so that i can compare all of this, as opposed to going into them one at a time - whether its in analytics or search console

[iliazolas]

Awesome video, quick question: both sites must belong to the same property. Do you mean that both sites need to belong to -> Account A, Properties: Site 1, Site 2 ?
