While before I thought that publishing daily was the key to good SEO ranking, after several months of such an approach, I understood that I was devoting too much time to counting rather than producing quality content. As soon as I started to publish whenever I wanted to publish something worth being published (happened once or twice a week), engagement increased and it became easier to update old articles.
i believe that there is no such thing as the right frequency of publication. It is much better to have a realistic schedule and stick to it for several months than publish daily for a couple of weeks.
