We have clean site, friendly navigation, good content, fast loading pages on dedicated server and forums with over 500.000 posts, but for some reason we didn't build very strong community yet. Let me add that we have very strong competitors on one of the smallest markets in the world. Site is focused on cosmetics, fashion and similar.
Share your advices how to lower this bouncing rate (besides good content). I have in mind firstly to remove one of the banners, leaving only one and maybe some promotion along with redesigning portal (maybe even with xenforo).
What do you do to keep visitors on page and keep them coming back?
