For example firefox went for basically (with ignoring few things):
id ; host or url ; title ; frequency or visits ; typed ; lastVisited ; firstVisited
Which makes it really easy to get your top most-visited websites, which can be useful for suggestions or a homepage but dangerous if it ever leaks out a bit. (pic attached where you can see that I heavily used twitter and fedi, this db is few years old)
While I would naively go for something which is probably less-database-like and more log-file like:
id ; visit day ; url ; title
Which means that you would loose suggestion ranking/sorting based on visits frequency but then it could be done by the date, since even if you went a lot on say myspace for ten years, it's basically dead now.
