They Yated shidduch forum on how to get dates was a 2,000 word column, but these are some of the highlights culled from the various response.
1. Dealing with shadchanim- make it easy and pleasant for them to work with you
meaning
A. Make sure what that what you are looking for is something they can find and get a yes from the boy for. E.g. a girl from a simple background whose dream is to run a playgroup for children but insists on marrying the next chazon ish and she will support him. That may be a lofty dream but hard for a Shadchan to fill and not one they will invest time in.
C. Let shadchanim know you appreciate their efforts on your behalf. If you get to a date #2 or date #4 show them your appreciation. They deserve it and they will respond in kind to people who appreciate them and treat them as such.
E. Get back to them in a timely manner (quickly). Make sure to give references who are reachable and will also respond in a timely manner.
2. Networking outside of shadchanim
A. Consistently encourage extended family members/ friends/ acquaintances to to keep you in mind and look out (network) for you.
B. Look into using various effective online (and kosher) matchmaking sites e.g. YU connects.
C. Single friends who are looking for similar boys to who you are looking for are a good resource.
