Using Facebook Base Pixel on Presell Website AND Money Website??

Is it best to put the base pixel on both my presell and money websites? They are both clean URL's (meaning they haven't been flagged on previous Fb accts)

I have the conversion pixel on the thank-you page of the last website - and Fb is showing conversions - but I was wondering if perhaps I'm not helping the algorithm by not having the base pixel on all websites of my funnel?

Thanks in advance for any help

Well, I would say, paste the pixel where the actual conversion is happening. But it depends on your funnel.
What is your intent? Do capture Leads or do you sell a product/service?

It is a good practice to place your pixel where most of the conversion is taking place.
