How Google Consider Separators in Title Tag

*)The only thing that isn’t a really great separator is Underscore, because you might have a_b and Google treats that like a_b instead of a b.
*)Spaces, commas, pipes, dashes are good separators from an SEO point of view.
*)In general, we should focus on making a title that looks good to users and we could use any of the separators like spaces, dashes, commas or pipes.
*)Any of the separators that you think looks good for users or converts well can be used in the Title tag as a separator, as there is not much of a difference from an SEO point of view.
*)Stay away from underscore separator, it’s not recommended at all.
