This is something I find I struggle with. In addition to their website, I check each agent on PM, QueryTracker, check the authors that they rep (if I can find them), read any interviews I can find. So far, I think I'm doing pretty well with this. If I find a novel they represent that's similar in setting or theme, I mention it and say it prompted me to contact them for representation (Example: "so-and-so's TITLE also has parents that feel they can control their child's fate . . . "). Or, if in various interviews they say that they like steampunk and circuses and that's what mine is, I'll mention that.
But then what about agents that don't currently represent anything quite like yours, but you still feel that they'd be a good fit for you? They have made lots of great deals, they do represent your genre, and you like how they come across in interviews. That's hard to quantify in one sentence in a way that doesn't sound really lame.
Lastly, some agents say if feels like ass-kissing and a waste of the precious words in your query to do this, but then others state it's important to prove you've done your homework on them so you're not sending off a bog-standard query letter to every agent in the business.
How do you personalise queries, or do you not bother?
