If your data looks like this: 

%hoh = (
  user1 => {
    Website => ['website1', 'website2', 'website3'],
    type    => ['type1','type2','type3'],
  },
  user2 => {
    Website => ['website1', 'website2', 'website3'],
    type    => ['type1','type2','type3'],
  },
  user3 => {
    Website => ['website1', 'website2', 'website3'],
    type    => ['type1','type2','type3'],
  },
);

Then try something like this (untested): 
for my $user (sort keys %hoh) {
  my @websites = @{ $hoh{$user}{'Website'} };
  my @types = @{ $hoh{$user}{'type'} };

  # assume we have the same number of each?
  unless (scalar(@websites) == scalar(@types)) {
    die "number of websites is different from number of types!";
  }

  print "$user :\n";
  for ( my $i=0; $i < scalar(@websites); ++$i) {
    print "  $websites[$i]\n";
    print "  $types[$i]\n";
  }
  print "\n";
}

However, if you go with data like this: 

%hoh = (  # actually now a hash of arrays of hashes (HoAoH)
  user1 => [
    { Website => 'website1', type => 'type1',},
    { Website => 'website2', type => 'type2',},
    { Website => 'website3', type => 'type3',},
  ],
  user2 => [
    { Website => 'website1', type => 'type1',},
    { Website => 'website2', type => 'type2',},
    { Website => 'website3', type => 'type3',},
  ],
  user3 => [
    { Website => 'website1', type => 'type1',},
    { Website => 'website2', type => 'type2',},
    { Website => 'website3', type => 'type3',},
  ],
);

Then your code becomes (untested): 
for my $user (sort keys %hoh) {
  print "$user :\n";

  # each element of this array is a hash ref
  for my $data ( @{ %hoh{$user} } ) { 
    print "  $data->{'Website'}\n";
    print "  $data->{'type'}\n";
  }
  print "\n";
}

So, depending on what you need to do, pick the data structure that makes your life easier.
