So this may a real dumb question but as far as internal link structure goes do all the pages have to link together for Google to approve of the structure? What I did was I built a three page adsense landing page site using html. I then used one of those 3 pages to create many more additional pages. All the pages have 3 links at the bottom that point to the 3 main pages but many pages do not point to each other. The main 3 pages are index contact policies There are around 84 additional pages that do not point to each other but all point to those main 3 pages. Is this o.k.?
When speaking of Internal linking it is a way to help Google and other Search engines to navigate around your site and index your content. You should make a sitemap and upload it to Google Webmaster tools. That will help google navigate on your site and index all or almost all of your content. With Google Webmaster tool you you can also see how many of your sited Google have submited to its web-grawler.
