Ribosome recruitment in eukaryotes happens when eukaryote initiation factors elF4F and poly(A)-binding protein (PABP) recognize the 5' capped mRNA and recruit the 43S ribosome complex at that location.
Translation initiation happens following recruitment of the ribosome, at the start codon (underlined) found within the Kozak consensus sequence ACCG. Since the Kozak sequence itself is not involved in the recruitment of the ribosome, it is not considered a ribosome binding site.
