Assume a website has quality content, let's say it's about a topic that does not change: a company whose services and staff stay the same, and they have no news to speak of. The content is accurate, it's just static.
Will this site always lose in search engine results to the sites of similar companies with similar websites with, say, a simple piece of content (e.g.: home page with a "what we're up to lately" subsection) that changes monthly?
I get frustrated with clients who are given tools to update their sites, but don't. My intuition is that by not adding "fresh" content to their site, even minimal content, they are hurting their search position in a way that's significant. Is that a valid intuition? Are there studies showing this is so or not so? I don't want to push clients to put more on the web if there's not going to be a return for that effort. I was considering building an automated tool to allow clients to set a weekly, monthly, etc reminder to add or update content. Any opinions on how much is enough for the SEO boost? Not every site needs a blog or has regular press releases.
