Doubts without affiliate network

Hi Guys ,

if I work with an affiliate network everything is clear because I have my landing with iframe and my thank you page.

Problems start when i take partnership with a website or a producer without affiliation network .

Questions:

1. if i send my traffic to their sales page i can not install my facebook pixel so How could i do retargeting?

2. Without my thank you page (after their sales page ) how can i track conversion? and i could i calculate my ROAS ?

3. if they don t provide me PostBack URL how can i use Tracking system ?

Do you guys have any ideas to help me because I love working as an affiliate for products that I choose but without an affiliation network....

That's a totally different case on all possible reasons anyway for any service, I hope you will get matter with that. You should run your traffic immidieately only if you really want to get something big like that and that's really matters overall for everything.
