To add to my previous post- there is a big difference between "interest" and actively recruiting but obviously you need to get on their radar first. The way I see recruiting is this: the colleges maintain a prospect list- a list of kids who either have contacted them and from their email, they seem to fit the bill or they have seen them play and these kids get added to the list.
If the coach has seen your kid play and then your coach gets a call, then there is some "hope" as something sparked their interest. Depending on the program, the list of potential recruits could be very very long. For example, if your daughter is a freshman SS, odds are the college has their eyes on 20-25 SS at that age group and the list is ever evolving as new kids get added and others get removed.
If your daughter is young- cast a very very wide net. you never know when a D2 coach is moved up to a D1, or a MAC/Horizon coach makes the move to mid major. Its really hard to gauge MOST kids potential talent level at a young age (some are late bloomers, some top out). (AND I am not saying anything is wrong with MAC or Horizon, just making a point to cast a wide net)
Make sure she is playing on the highest level team that matches her abilities. As a freshman and sophomore, your really need to get out there and play the best competition to build a resume. The Coaches want to hear that your daughter faced teams out west. If your kid is younger than that, i would only recommend that elite pitchers leg the miles.
The whole recruiting process puts a bad taste in alot of peoples mouths (dissappointment at camps they attend that appear to be a cattle call). Make the most of the experience and enjoy it. Use this as an opportunity to stress the importance of selecting the right school and try not to let your frustrations show. your daughter will pick up on this and might say to hell with the camps which is NOT good.
Unless your kid was personally invited by the Coach to attend the camp, I personally think only pitchers and power hitters get the most bang for their buck at camps because those kids can be spotted quickly amongst 200+ kids at a camp. Coaches always watch pitchers and word of mouth travels fast on a power hitter. If your daughter doesn't fall into this category, be selective on the camps- go to camps that you think fit her abilities and schools that she is interested in academically and try and establish some sort of relationship with the coach. send an email that you are going, and make sure she introduces herself and follow up afterwards. If you have a travel ball coach or are part of an organization that has a history with recruiting, it will make it a little easier.
I hope others chime in and give some advice and share their experiences too
