Here is part of a recent communication I received, "But that is very specific to making sure the right keywords (content) are going in, moreso than a function of frequent updating. For some key word combinations there is little competition. We mostly need to make sure that program people are getting in the text on the site the combinations of words which would facilitate their audience finding them. IE we more need the right word combinations than a site that has great "gravitas" in the Googlesphere."
I have been lobbying for regular updates and new content as part of having a quality website. I would love to hear your comments, especially if they are backed up with references to quantified information.
