Issue

  • Can Angular Portlets be crawled by SEO tools/Google?

Environment

  • Liferay DXP any

Resolution

  • By default, Angular Portlets in Liferay are not SEO-friendly and cannot be easily crawled by search engines like Google, because:
    • Client-Side Rendering (CSR)
    • Angular is a Single Page Application (SPA) framework that:
      • Loads content dynamically in the browser.
      • Renders HTML via JavaScript after the initial page load.
  • Google and most SEO tools cannot crawl or index JavaScript-rendered content reliably, especially when it’s inside a Liferay portlet container.
  • Liferay doesn’t server-render Angular content inside portlets. This means:
    • When crawlers hit the page, they get an empty div or loading skeleton.
    • The dynamic content isn’t indexed unless server-side rendering is set up or pre-rendering is used.
