On the online dating blog from my singles online dating website i post only a couple of times a month, when I have a good advice for visitors.

Just do it very frequently, if possible daily.. it will increase google crawl rate of your blog.

almost everyday i couldn't help not to touch my laptop and every day i updated my blog with fresh content on it.

Sometimes, I write my news on Atcities/com, it is easy and quickly.

Once in a week or twice in a week for me. I love to blogging...

I used to blog every day but I decided to stop because wasn't profitable for me.

Now a days 2-3 times in a week.

DON.

I don't post near as often as I should, I can remember reading somewhere that if you let 4 months pass with out a post your blog falls in ranking from what ever rankings you had.
Not positive about that 4 month figure, am thinking 6 weeks is a better figure (based on the concept that it takes (or used to take) Google 6 weeks to circumnavigate the globe)

A better answer depends on what it is you're wanting to get out of blogging.

My reasoning is to blog "in support of" a main website, towards that end I have what I call "first tier" and "second tier" blogs. The second tier I simply republish authoritative articles on the topic of the main target site and use them to link towards the main target site.

About ranking: to speak authoritatively about ranking one must consider that there are over 200 determining factors going into Google's decision making process to choose who should rank first, and who should rank second...

If all things are "equal" or "relatively equal" then the algorithm resorts to other considerations: If site A is ranking and you are site B... and the two of you are almost equal... if you post more often then site A does, you'll overtake him/her.

so... saying I blog X amount of times works (or fails to work) in increasing one's ranking depends on the competition, he they are "asleep at the switch", your blogging frequency will help more than otherwise.

hope that helps

I blog (i.e. mostly reply on blogs) almost everyday. It makes me feel good and I get to use my free time to the max visiting various blogs and writings and peoples views and what not.
I do not have any 'fixed' place or type of blog to visit.They are so varied and so interesting,why limit the experience !
