Facebook Ad - Landing Pages

Hello,
I had a meeting with a marketing group that stated that the Facebook landing pages alters the algorithm and, therefore, the ad's effectiveness. Does anyone know anything about this? And if so, are there any landing page templates for Squarespace that you can recommend?

hey buddy, i already had many meetings with the facebook marketing team and realized that they have a lot of differences between them.
It seems to me that each analyst has his own perception and his own understanding of the algorithm.
I don't know exactly what I meant by that, but I've always used landing pages and I've never had a problem.
Did they mean to change the pixel events?

yes, fb's landing page is changing its algorithm
