I've been posting more often on my rant blog over the last few months. And I've noticed that I'm getting quite a bit more traffic to it. I haven't done any link building. So this effect must be entirely due to the increased frequency of posting.
I suspect part of this is because regular readers to it are returning more often. But I'm also getting more search engine hits - and not just for the new posts.
I haven't looked deeply into this but it seems that regular and frequent blog posting lifts your general rankings a bit. When the frequency drops, the opposite happens.
It's as if Google is detecting my "blog pulse", and rewarding me a little if it is strong.
I've often read this on various forums and blogs. But it's good to see it confirmed.
