Linking Analytics with Instagram Ads

Hey guys,
this is my first post, so i hope its placed right and I'll hope to become a part of the opportunity.
We are promoting restaurants with Instagram Ads. Now we are trying to track those results.
For normal tracking we are creating a special landing page where customers can immediately preocede to placing an order.
Our fear is that some customers are reconsidering after seeing the ad and ordering later that day or on one of the next days.
Is there a possibility to track those convertions even if they just google the restaurants days after seeing the ad. We informed ourselves, but didn't manage to find an easy solution, especially because in Germany its you now have to accept the cookies, so the Facebook Pixel might not be activated when its on the main website of the restaurant.(They contact the restaurant over their webseite, not our specific landing page.)
I hope thats understandable.

Tag the link to your website using GAs URL builder. The traffic will then look in the report with the dimensions you define. Note that you can only track traffic where your GA code sits, so for example, it wouldn't show traffic to your Instagram photos, as that's on Instagram's website.

 

yes, you can do that
