Well, the thing with snakes or any sort of live animal is that you don't have a constant 'for sale' supply all the time. I hate when I go on a breeder's website, and they have 1 or 2 animals for sale and no updated collection page. I don't think it's neccessary for the collection page to contain each and every animal, but it should at least give the customer a scope at what type of animals and morphs they can expect from you, that way they know whether it's worth coming back for another look again or not if you have the type of animals they're looking for.
Internet marketing, there's tons of sites out there, so if they look on yours and don't see what they want, chances are they'll just carry on and not come back.
Plus, I love them when they're informative, they can be alot of fun to read!
