Are there certain times of the day that it is better to update content or blogs? How do I find out what time is best for a particular site?

Trying to figure out how to best optimize timing of new content... including blogs and other on page content?

Have a look at how users behave on your site throughout the day -- maybe using a real-time stats package like Woopra.

As Riggz says, it's usually the case that most sites will have their own natural rhythms when it comes to how audiences engage. By monitoring the busy times of the day you'll have an indication of when your users are more likely to want to engage with new content.

It's also a great opportunity for a bit of testing. Over the next few weeks, experiment with different days of the week and times of the day to publish new content, and use a service like Twuffer.com to schedule tweets to the new content at different times of the day. In my own testing, I've found that tweets sent toward the end of the working day can be the most effective way of gaining traffic to content posted at lunchtime.

Your mileage may vary... but it wouldn't be fun if it didn't

I think it really depends on your niche, clients and whether you are targeting consumers or businesses.

For businesses, or consumers that are in the 9-5 bracket mornings always seem to be the best across most audiences, its before people get busy, sidetracked, afternoon meetings, etc... we have some of our restaurant email marketing clients send out emails around 9:30-11AM to their subscriber lists to try and boost their lunch crowd.

I think if you were targeting consumers on maybe a shopping site, fun blog, music site or something in that regard that late afternoon evening might work better, but I honestly have little experience in that market.
