Is this random or something we can optimize ?

i mean how to make this sitelist ?
Is this something we can make / optimize for SEO or this is one of google feature that randomly generate ?

yeah, that's something that you need to do for your site, but I don't remember how it's done. I think it's about having a clean site structure and maybe using some schema markup or something, I really don't remember but I know for sure that you can do this for your site but it's google who ultimately decide whether or not to create those links

Yess because sometimes i got like 3 sitelist, but sometimes only 1

but i see some websites constantly showing 4 sitelist all the time

Been searching how to optimize it but i cant seems to find the right keywords for finding the guide or topics
