"How often can you post to your blog?" is a very popular question, to which there is absolutely no right or wrong answer. Twice a month? Twice a week? Twice a day? Just one single time a day?
You'll find plenty of different blogs promoting different scheduling for blogs. A lot of them recommend posting once or twice weekly, maximum. Here's my take on the issue - both blog posting schedules that matter, also to what types of blogs they're applicable.Understanding Posting Schedules
First of all, you need understand that there is absolutely no right/wrong answer for this question, as I've already stated. Different timings may or may not work for various kinds of blogs.
The following advice is not something that I believe works for each blog, but it's what realy works for most (after my research).
How User Engagement & Blog Posting Are Related

First of all, it's a myth that readers will be annoyed in the event that you update your site daily. It's just a myth, without real evidence to back it up. One of my all-time favorite blogs sends me an e-mail each day or every two days.
I love it. It gives me more information when compared to a month of Sundays of autoresponder messages from any blog.
That said, users also don't mind if you post only once weekly. Honestly, readers are only looking to see how they are able to benefit from your blog - that's virtually the only reason why they're there and just why they registered to your e-mail list (unless they're friends or family.
Alright - let's get right down to the posting schedules.
Daily/Multiple Times EACH DAY
Oooh! I feel I'll provoke a substantial amount of controversy with this particular one, aren't I?
But yes - I really believe that posting multiple times each day can be good for blogs. If for reasons uknown you're not available to post multiple times a day, then you should make an effort to post at least once a day. For nearly 95% of people reading this post, that's what you ought to be doing.
You should definitely post this often if you run among the following blogs, or take part in one of many following business strategies.
Informational/Tips Blogs
Take this blog for instance - it deals mainly with blogging, Online marketing, and SEO tips. In other words, it provides valuable information to those who read this blog regularly.
To be branded being an authority in your niche, your blog needs to have just as much helpful, quality content on it. If which means posting 3-5 times each day, go ahead.
Most blogs on the web (including yours) will belong to this category.
Personal Blogs
Let's face it - personal blogs usually don't get much traffic. The prior rule about readers coming solely for personal benefit once again applies here.
There's little benefit a reader can gain from your own personal blog unless you're A.) Hilarious or B.) An excellent writer who is able to hold people spellbound.
Chances are, you're not either. But let's just suppose that you decide to go ahead and start a personal blog regardless. You need to be posting once per day.
For most personal blogs, I wouldn't recommend more often than once a day (because hey - people like to have a while to take into account themselves, and not simply you).
However, once each day is usually necessary, if you would like any sort of traffic. For the reason that that the people who do follow and read your blog regularly obviously think you're a fantastic writer or funny. And, they want their daily dose of fantastic funny (but again, don't overdose).
The Benefits
No doubt about it, there are particular benefits you obtain from posting daily that you won't get if you post less often.
Search Engine Optimization
Although this cannot be outright proven, it's becoming clearer that Google favors blogs that post content frequently throughout the day.
When you publish a new post, Google is automatically notified. Eventually, their spiders will get to crawling your pages and ranking them.
If they're notified quite often, which means you blog often. If you blog often, which means your blog is active and regularly providing content to your readers.
Everything said, this can not be proven, but it's a general trend I see after conducting research in the SERP's.
Alexa Ranking
Although posting 10 times each day mean that you'll automatically be promoted to the top 1000 blogs, the blogs that engage a higher-frequency posting schedule often rank higher, compared to blogs that post less frequently with the same quality standards.
Case Studies
I recently found a forum thread where an Affiliate marketer laid down his technique to go from $0-$200/day in AdSense earnings in 8 weeks flat.
What he basically did was outsource cheap content writing jobs to freelance article writers. He hired a great deal of 'em, posting on his blog 30-40 times. Every. Single. Day.
The result? He's sitting pretty with $200/day in AdSense earnings. In 8 weeks, flat. And that's only 1 of his online businesses.
Let's take another example. A good friend of mine, for whom I recently guest posted, includes a prestigious Alexa rank of 44K, amassing a total of 14,000 page views each day.
He posts a minimum of three times a day. And it's really taken him a measly 2 yrs to be at where he is right now.
That's pretty good, in the event that you ask me.
HOWEVER...
However, this rule doesn't apply to all types of blogs. Actually, posting multiple times a day, or even once daily, would be disastrous to certain blogs.
Business Blogs
By business blogs, After all blogs that belong to already established, offline companies - Wal-Mart, for example. These kind of blogs shouldn't - I repeat, should not post a lot more than twice weekly (and really, once weekly is all you have to be doing).
Why?
Simply because those forms of blogs aren't designed to be updated regularly. Most of the time, they're simply about discounts, or business news.
They have no dependence on SEO (unless it's a local service people actually seek out online). Essentially, it's only a front that says "we're online too".
Do You Have Something Worthwhile To Say?
You have something worthwhile to say? Something that will actually help/inspire/motivate people? Do you?
You don't?
Then don't say anything.
Simple as that. If you are not sure about whether you need to blog everyday, then blog if you have something to say.
However, try to maintain some sort of consistency. If you get sudden post inspirations, then go on and write the blog posts , but don't publish them - yet.
