I have a blog that updates 7-12 times a day with content, but it is a news aggregator site and needs fresh content to remain relevant.
On most of my sites, I upload content monthly, 1-2 pieces, usually LONG content(2,000-7,000 words).
I have a site that I am building as an authority in a seasonal niche, and right now it isn't the season, so I won't upload content, but during the season I upload content 2x weekly. I use the off season to build long content.
I don't notice any more or less Google love from the different posting schedules, on my established sites(2+ yrs old).
I do notice that when I am trying to establish a site, that my rankings will start to drop if I don't put fresh content on it at least once a month, no matter how long the content is. And that continues until I build solid quality backlinks to some content and the entire site has aged for a bit(including when I used aged domains).
