I put structure at the end of this tutorial because it is natural as an internet entrepreneur that you may be all focused on website structure. Perhaps you are thinking that if you could just happen upon the right structure your business will explode (another power word:)
The internet does have several quirky structural characteristics about it but, structure does not determine the success of your website. There will be many "gurus" who may try to sell you their structure. Avoid those "opportunities" as if you will contract Ebola virus from them.
You are not writing for a newspaper, or a school term paper, or a doctoral thesis when you are writing content for your website.Web readers are "skimmers." Keep your paragraphs short.
There is a reason that Twitter keeps its' "tweets" to 140 characters or less (number of letters). The usual web reader has a very short attention span. If your content looks daunting your site visitor may just leave.
It is also a good idea to place images on you pages and posts on the right side of the copy. Neuroscientists that have studied the reading habits of web readers have been able to show that they read in a "F" fashion.
That is, they skim from right to left (no matter the language) and then skim down the left hand column. Images placed on the left will cause them to skip the printed copy and just look at the images. Curious, eh?
It is also a really good idea to include images embedded into your copy as they tend to evoke emotion. Remember...emotion "super glues" memory. Just make sure your images are consistent with your content.
Finally, be sure to have subheadings and some bold highlighting of your copy. If the regular internet reader skims you want them to at least focus on the bold main points. Here again the idea is to get your reader to remember your content so they will return.
