In the world of SEO, the search engines’ indexing programs – commonly referred to as “spiders” – play the important role of analyzing new websites (or new content added to existing websites) and adding their content to the lists of pages that can be displayed in response to user queries.
As a result, facilitating the easy movement of these spider programs throughout your own site is an important part of optimizing your content for natural search traffic.
One of the best things you can do to help the spiders index your website is to create a sitemap – a page listing links to all the other pages on your site. There are plenty of different automated tools that can generate these important pages for you, though you can always create a sitemap by hand if your site is small.
