Further to Wayne's suggestions, I would try
emailing links to pages from your websites to your K of C members and any
parishioners you have on your address book, as information. Especially any new
pages, articles, news that you post.
At the same time you could suggest that they sign
up for the DeoWeb news which might get some of them interested or at least
connected.
Don't get discouraged!

Paul
