Rated 5 out of 5 stars

Excellent add-on!
Thanks for updating it again.

One suggestion:
Support for Sitemap_index.xml files.

Currently only a Sitemap.xml file gets detected if I'm correct.

Best regards

Thank you for your feedback. I just implemented parsing of robots.txt. In the future SenSEO will check robots.txt sitemap location, when it is specified there.
