The document discusses strategies for developing and managing theme-based websites. Some key points include: 1. Themes tell a story to establish authority on a subject for search engines and users. Objectives and competitor analysis should inform theme discovery. 2. Additional themes can complement or branch from the main theme. Landing pages must optimize the user experience and convey depth of knowledge to search engines. 3. Traffic analysis can identify unexpected themes. Competitor themes should be leveraged and inbound/outbound links studied. 4. Sub-themes can address emerging search phrases. Multiple themes require separation and management to maintain a clear focus.
