could someone recommend me a Magento extension which would be capable of generating both - XML Sitemaps and RSS (or Atom) feeds and fully comply with recently published Google's best practices for XML Sitemaps and RSS/Atom feeds:
Additionally, the extension should have options of splitting generated XML sitemaps, pinging search engines and would respect canonical versions only (meaning that only those should be included in generated files). These are the main requirements, at this moment.
I'd consider all options as my own attempts to find such extension (or even combination of several) weren't successful.
Thanks in advance!
