Question

On site I have div containers in this sequence:

1. Less important left side bar
2. Less important right side
3. At last the core center content

As the core content comes after side bars; does this have any bad impact on SEO. If yes than how can I bring center div before sidebars. Need fluid center and fixed sidebars.

    #left {float:left;width:200px;}
    #right {float:right;width:200px;}
    #center div {margin: 0 200px;}
    <!--X-->
    <div id="left"> ... </div>
    <div id="right"> ... </div>
    <div id="center"> ... </div>

Answer 1

“Apart from the most commonly known things like keyword reach titles,
key-phrases density of the content, good meta tags etc. there is one
aspect less known: the fact that each part of the content is ranked
based on its relative position within the whole content of the page
and also on the degree of uniqueness among the content from all the
pages of the site. This comes from a simple, natural principle that,
if a page wants to “say” something, it will start with it and put the
rest of less important things after. So the most important part of the
content should be found at the beginning.But, if a portion of content
seems to appear on too many pages (like the headers, menus, sidebars
content etc.), then it gets to be considered “common” – which is the
opposite of special, unique -, hence less important from the content
point of view, bearing less “SEO juice” as it is called.”
