I think this might be a stupid question but I'm going to ask it anyway. I am building pages to optimize for different keywords, so eventually my site will have hundreds of pages. My question is when I link from one page to another, do I have to have every link on every page? If I did than my home page would have hundreds of links on it. So does it matter if not all of them link to each other? I hope all this makes sense.
Well, you could think of your website as a shopping cart. You can have a navigation menu that links to your major categories: News, Biography, Links, Recipes, etc etc. Then, when I click on your News page, you can have links to your "sub-categories", such as North American News, Yesterday's News, Stupid People News, etc - where each one of those is it's own page or landing page to even deeper categories. See what I mean? And then you can pepper in links back to your upper categories and home page from within those deeper ones. Along the top of each page (just below the site banner), you can have a breadcrumb trail ... this will also help your visitors to "climb back up" to your higher level categories also .... Now, a site map would be the thing to put up for your visitors to see where you would list all your links: home page, major categories, sub-categories, individual pages, etc .... So you would just have to do that once.
