Imagine a piece of paper, just a white sheet. Put your home page on top. Below it, put the pages that are at the same level as your home page. Below that put the sub directories that you have on your host and their pages below them. You really should not have sub directories of your sub directories (search engines will not easily find them) so it stops here. Draw a circle around it all and start adding your internal links drawing lines between your pages. Now draw outgoing and incoming links (one line can represent several links).
This is what I call site mapping, your site structure. You should build your site structure the same way you build your page structure, with extreme care and with a purpose. AND, your structure should reflect your strategy. You can have 2 main strategies for your home based business site, so we will discuss 2 main structures as well.
Two types of structures and strategies
One type of structere is when the main purpose of your site is to “sell” the things you show on your home page (or main selling pages). This is a very simple strategy and everything should point mainly to those pages. Your other pages will have one goal, lead your visitors to your home page and try to sell (or offer) them your product or service.
This means that all your resources, all your work should be concentrated on improving and updating your home page, so your visitors will come back to it. All your optimizing efforts are concentrated mainly upon your home page and PR (Page Rank) and keyword optimization will be of the utmost importance to that page. This will result in five or six, links on each page, deliberately concentrating PageRank on a small number of sales pages which you want to rank highly in search engines.
The other strategy is that you have several main pages. Your home page and several pages at the same level that are directly and logically (inter-)related. Visitors can jump around, go from theme to theme and find several things they are interested in. Your main strategy is not to lead them to your home page, that is only something like a welcome page. Your main strategy is to keep your visitors on your site or get them interested in coming back.
