Let's gather the advices on website updates!
 

According to your opinion, how often your website should be updated? What website updates are the most important for a website? What advices would you provide for people who are going to update a website?

If you have a blog you should update at least every two days. If you have a TGP or MGP you should update at least every day, the same thing goes with a tube site. For a high quality niche website you can update once a week.

Just my 2cts

A short list of things that I do
Technical stuff
1) always update my sitemap
2) check the new links for title and alt in chase of image links
3) new links are always on top of the old ones.
4) test every new page in each of the three browsers IE/Firefox/Opera
Marketing stuff
1) the new updates are part of my weekly newsletter
2) the menu from the main page is updated always with the new links

Hope to be useful, :)

Depends on the type of site.

If you are talking about a members area, there is no such thing as too often.

I mean, general tips for all website types!

I think the more interesting your website and higher the demand on product or services it offers is the more often its updates should take place.

Yes, almost all advices are quite good !

I do about 3 to 5 updates a week for my member sites. One 1 gallery every other day, and another just gets 3 galleries once per week - I may change that to 1 every other day though.

I suggest that it is always good to provide website with fresh content like adding news etc. Both search engines and people will epreciate this!
