Limit the use of Secure Server as a landing or home page
While search engines can spider secure server hosted pages, these pages often require that a visitor fill out a form or log-in with a username and password before reaching content. Search engine robots simply leave a page when they encounter such forms. Thus, search engines often either penalize or downgrade sites that use immediate URL forwarding, especially from a home page. To avoid creating form-filled pages that engines will ignore but still capture the customer information you need, try doing some internet marketing research and a site path analysis to understand how you can direct customers from a landing page to a secure server pages without losing them.
