Canonical URL and hreflang tag automation

[gdWebct]

What's the most efficient way, if it exists, to dynamically add (or automate) the canonical and HREFlang tags to pages, without manually adding  <link rel=”canonical” /> onto head section of each page component? I've seen a possible solution (no JDK 11) in this library: https://github.com/otarsko/aem-seo-canonical-url

And third party tools for XML sitemaps like: https://www.stateofdigital.com/hreflang-sitemap-tool/ 

Any other options available? Thanks for any feedback!

Hi,

Checkout https://developer.adobe.com/experience-manager/reference-materials/6-5/javadoc/com/day/cq/wcm/api/va... for adding hreflang tags

Ex: 

List<PageVariant> pageVariants = pageVariantProvider.getVariants(currentPage, slingRequest);

Thank you, @Ravi_Pampana we'll  have to check this method out as well as the SAX transformer pipeline suggested by @arunpatidar. Appreciate your feedback!

you can use sling rewriter pipeline to parse page html and inject canonical and hreflang
