Let's say I add a blog to a mostly static website, or simply publish new content every week. Does that help the site rank better in search engines in any way?
Having fresh, accurate, timely information on your site matters more than most other factors in many niches:
If you try to make a site focused on any of these without regular updates, users will be unhappy with your site, and Google will be able to see users leave your site and prefer your competitors. If you are in these niches and are trying to compete for rankings in Google News, then fresh content is king.
On the other hand, much of the content on the internet is "evergreen". It will continue to be relevant for years. For most sites, having fresh content is much less important than:
With evergreen content, if you have to choose between constantly creating lots of fresh content and improving existing content while adding new content more slowly, choose the slow, quality approach.
With fresh content, there is often a "honeymoon period" in the Google SERPs where Google ranks the fresh content highly to test it out. Rankings often drop after a week or two. Many webmasters take this as a call to keep creating fresh content. Conversely, I have seen high initial rankings remain and even improve when the content is high quality, users react well to it, and the webmaster incorporates feedback from visitors to improve it. It appears to me that initial rankings fall only when the content is less helpful to users than Google's algorithms initially predicted that it would be.
