First, make sure your code is clean and well-structured. This helps search engines crawl and index your site more effectively. Using Drupal's Pathauto module is a great way to automate friendly URLs based on page titles and content. Also, don’t forget to use meta tags and page descriptions for better search visibility. For site maps, the XML Sitemap module is really helpful—it creates an XML map of your site which simplifies indexing by search engines. To manage indexing and avoid issues with duplicate content, you can control it through Drupal’s settings. Make sure your site is mobile-friendly; responsive design is crucial for SEO. Also, consider site speed—using caching and a Content Delivery Network (CDN) can significantly improve loading times. For a comprehensive SEO solution, you might also want to check out site ok.
