Drupal has a strong reputation for SEO thanks to its clean markup, granular control over metadata, and excellent module ecosystem. Core features like pathauto, metatag, and redirect give you fine grained control over URLs, titles, and descriptions.
The platform generates semantic HTML out of the box and makes it straightforward to add structured data through schema.org modules.
Performance, which matters heavily for modern SEO, is well supported through built in caching, BigPipe, and lazy loading. That said, SEO success depends more on content strategy and technical setup than on the CMS itself. Drupal gives you the tools, but you still need to use them thoughtfully to see results in search rankings.
