Sitemaps
Sitemaps are a facility that allows all engines to crawl all your pages more fully.
It is simply a list of every page on your site so that the engines can use it to reach all your pages.
Their best use is when you have a larger site of hundreds or even thousands of pages because in this case, without a sitemap, it is more likely for pages not to be crawled.
This applies whether you are running an ecommerce site of thousands of products or a blog with several postings.
The principles are the same.
We use software to help in this process of constucting your sitemap and then ensuring it is linked to from the main body of your web site, usually unobtrusively in a sidebar or footer link.
