My personal POV is that it’s important to show your users that “this is a place where things are happening” so I’d say at least weekly. 

It sounds like you have a lot of content/events, so I’d recommend showing a mix of what’s upcoming and what’s newest. 

Get in the beta of the Dynamic content widget if you’re not already. 

Agree with @DannyPancratz on weekly as well. I have a few things that end up sitting a couple weeks, but I try to change SOMETHING at least every week.

Haven’t heard about this widget, but I’ll ask my rep too!

Weekly typically and sometimes over the course of the week. We try to keep things fresh and a sense of change and evolution vs. it feeling static. Even sometimes just changing “how” it is presented can shift engagement and make things feel new.

Home page, you mean .com or community home page?

We update .com homepage once per week. Updating the community home varies, sometimes I update it daily, sometimes once per week.

Between the ‘featured content’ and top announcement ribbons I could change it more than once per week to highlight latest stuff.

Also started a weekly roundup of the Community publication.

Agree with most of the points here. We update ours 1-2 times a week.

Overall: We change the topics on the go, when we see something good. We have the goal to highlight a mix of a bit older and newer topics. 

Some of our Content and when we want to highlight e.g. an event, that is staying up like a Month. 
Other content written by our team or guests is up for max 2 weeks. UGC is put up way more spontaneous, when it is older than 2 weeks it comes off mostly, unless there are still contributions ongoing. 

We had a pretty set content calendar when what kind of format was published, but this wasn’t natural and also not really working for us as a CM team, so we went back to posting at the best point in time for the content piece.

Other Question, do you know how often your active members are visiting the Community? 
I’d orientate on that factor. 

We strive for weekly or bi-weekly. The nice thing is that so far our other departments have started seeing the value of the Community and have been more willing to submit content. 

@Lena H. had a good point about providing enough content for the more active members and adjusting to how often they visit.

We did some analytics and discovered that we get the most logins on Tuesday, so we try to post on Tues morning.
