First of all, never put effort into a recruit you haven't fully scouted unless it's a last resort.
I can go into specifics about what I do, but here's a few basics I quickly jotted down, and I'd be happy to hear other coaches thoughts and elaborate further or discuss strategies.
-Focus first on local recruits first. Scouting some further states is fine, and you can put limited AP into them in recruiting, but it's usually not a good idea to battle for the further recruits, so you'll want local options.
-Scout DI as much, if not more than DII. To add on to the previous point, if you do scout states further from you, better to do it for DI than DII, because if there is a DII recruit of value, there is more likely to be a battle vs. some DI recruits that are below the level of DI humans and you can get without only AP.
- After you've scouted states or attended camps, don't scout past level 1 for any recruit that is a D in athleticism or defense, unless they are B or better in the other (and then only maybe because I find ath/def are correlated to an extent). Coaches obviously value different attributes, but if you haven't learned this yet, players with bad Ath are not good for your team.
-Don't focus on what the player's level 1 offensive rating is. It's an added plus if it's C or better, but players could have great potential you wouldn't see at level 1.
-Scout all players that have B or better in Ath. Then look at C at recruits and prioritize those with higher-level 2 Def, then Off.
Once you are at level 2, you'll have a better idea of what attributes you want to focus on, but still don't put additional scouting effort into recruits that are D in at or def.
-As you get to each level, you have more information to start making better decisions from there.
