its definitely a better idea to make a new episode per page than to add pages to a preexistent episode, however i understand how per-page updates can get tiresome, and daunting to new readers. if you can make 2 to 4 pages over a week, or even a fortnight, id post them together in weekly/biweekly updates. if you only make a page a week, though, you could just do episode per page, as many successful comics do, or post it page-per-week somewhere else like tumblr, and then put them together into scenes or entire chapters here. it depends on the kind of pacing youre after.
