Your HTML document should have a proper structure. A proper structure is defined by W3C here. All what you need to do regarding your page structure is to choose a proper page header and place it on your page as h1 element. Then develop a hierarchy for your page content and you may consider using h2, h3, etc. for each paragraph. That will make it easier for your readers to find what they are looking for, they need to look at the headers or sub headers, and read the paragraph beneath it. Search engines just like your readers will also find the page easier to understand and categorize.
I recommend you to place each paragraph with its header (h2 or h3) in html div, give the div an id, and then place few links in the top of the page that points to each sub header in your page. That will make it much more easier for your readers to navigate within your pages, and search engines will appreciate it.
It may sounds so silly to mention such things. From my experience by looking and evaluating web sites, i strongly believe that 80% or more of the web sites I looked at do a very bad job in structuring their pages.
As you noticed, I believe that the better you make the page for users, the more chance you have to rank. No one told me that, but I am quite sure that is true.
