There are two main options here for online dating sites.
Israeli girls are more direct and straightforward than other Jewish girls (and maybe a little more mature and grounded).The advantage of a site like this is that (almost) every member is Jewish, and they allow you to see more detailed Jewish info, such as what type of Judaism they practice (Reform, Conservative, Traditional, Orthodox, etc.), whether your potential match keeps kosher, how often they go to shul, etc.Probably the most popular of these sites is JDate.com, which has thousands and thousands of members.In my case it just seemed to always work out better.So of the two options above, I would recommend to do both but give extra priority to meeting Jewish girls in person at social events. :-b In my opinion there are only a few things that are key in dating Jewish girls. Along with this, Jewish girls are looking at marriage and children down the line.
