A nice initiative for n00bs.
Well, I, write as it comes from my brain. Thus, almost all of my posts are in simple plain english that could be easily understood by even the person knowing the most basic english. Moreover, I don't (rather can't) write a professional looking article. I just want to convey what I want to, to my readers.
In my opinion, putting images in your blogposts wherever necessary, or rather should I say wherever applicable, helps get the reader's attraction. However it isn't same for images that are completely out of context of the blog post. This way, it becomes a hinderance.
Make your blog attractive. An attractive blog has a great potential to harness the traffic. Add some pictures or slideshows as the header of your blog. It attracts the visitor, who, first of all notices your picture/slideshow, to read on. You can try a variety of things including Adobe flash, plain images, CSS, JavaScript and JQuery slideshows. I personally like Camera CSS- A JQuery-CSS based Slideshow. The plugin can be found on http://www.pixedelic.com/plugins/camera/, and since it is opensource and free, it can be modified in a variety fo ways as one wants. I have used this plugin on my blog header and, I feel it looks nice. (though it is somewhat of a PITA to add it in your blog)
Another big thing is posting frequency. Any blogger who is blogging in a niche anywhere close to personal or hobbies, should check out his/her posting frequency. One should not either post too much too often, nor too less. This happened with me. When I started my blog, back in February, I had too much content to start a blog, and more than that, the enthusiasm, and thus I posted 14 posts in around 18 days of starting my blog. When months passed, I started feeling the scarcity of content to blog upon. Since then, I am a bit careful about my posting frequency.
As for the posting frequency, beyond the scarcity of content, there's one more thing, that new bloggers should look out for, and this time, it's a well known fact - again related to posting frequency. Everyone knows that our newest posts appear on top of our blog, and the older ones move down. Thus, new bloggers should take care of timing in posting their content. Since the blog is relatively new with relatively less visitors, it is possible for your visitors to miss out on some of your posts, if you are posting too frequently. Posting very less frequently has its own disadvantages. Thus, I would like to suggest the new bloggers that give give your readers, time to notice your blog post. I personally maintain a posting frequency of atleast one blog post each week, which is in sync with my content generation rate, my time as well as in my opinion, good amount of time for my readers to notice my posts.
I just forgot the SEO Part. It is an important aspect to popularize your blog. Will add some more things later. Can't edit this post more than this.
