What's the best day and time for a webcast?

Here's an interesting question blogger Ken Molay is asking. What day of the week is best for a webcast? And what's the best time of day?

He's doing a survey to collect data, because as he notes, conducting tests on this sort of thing would be difficult. I completely agree that gathering hard data from tests would be tough, but I think most producers of frequent webcasts could get a pretty good hunch for which days and times pull well, just knowing some of the variables that are in play (like how popular the topic of each event is likely to be). On the survey front, I also worry about whether people's actions of actually attending webcasts at certain times will follow their responses, because quite often, what people *say* they'll do is quite different from what they actually do. But it should be an interesting survey nonetheless, and it's probably better than the hunches all webcast producers are operating on right now.

In July 2007, webcast vendor ON24 did an interesting study that looked at a lot of different data points with key webcast trends. They examined things like months of the year for webcasts, plus which days of the week are best for registration. But they didn't dive into the attendance question based on day of the week or time of day. (Here's a link to a press release about that ON24 report, with a contact name on how to request a copy of the PDF. I couldn't find a direct link to the report PDF anywhere, probably because ON24 wants your name first so they can sell you something. But hey, ON24 is the best webcast vendor out there as far as I'm concerned, so let them sell you!)

Here's my contribution to conventional wisdom on best times for a webcast...

Last October, IndustryWeek did 12 webcasts in two days. We called it the "Operational Excellence Online LIVE" web conference. Sessions started at 11am, noon, 1pm, 2pm, 3pm, and 4pm Eastern on each day (a Wednesday and Thursday). The target audience was manufacturing management. The majority of our audience is based in the Eastern and Central time zones, although there are still quite a few manufacturers in Mountain or Pacific. Overseas audience is generally around 5%.

Since there were lots of variables with these 12 sessions -- 12 different sets of speakers, 12 sponsors who did differing amounts of promotion for the event to their current customer/prospect base, 12 different topics of varying interest to the IndustryWeek audience -- it's hard to draw scientific conclusions. But in terms of attendee percentage, we can make some pretty good guesses.

We found that the first session (Wednesday at 11am ET) had the best attendance percentage. There were several others that had comparable numbers that were just shy of the first session's numbers, so I'm sure that's not statistically valid.

We also found that the 4pm session each day was by far the weakest in terms of attendee percentage compared to other sessions that day. This is despite the fact that both 4pm sessions had particularly good speakers and particularly interesting topics that are normally "hot button" sort of subjects for our audience. (We survey the audience after each session and ask them to rate each speaker, and out of 24 speakers for the 12 sessions, the speakers for the 4pm sessions were rated as the #1, #2, #4, and #8 presenters for the entire conference.) Good content, good speakers, poor turnout.

We had similar results for the 4pm sessions during our December 2006 multi-session online conference. Those two sessions underperformed from an attendance % standpoint as well.

As a result of these pretty convincing results, we've eliminated the 4pm time slot from future multi-session online conferences. We'll see how the numbers change in the future. Perhaps the 4pm time was too late for manufacturers, since a lot of manufacturing companies start and end their days earlier?
