a a little lost here and I want to know which one is the best way to do it
I have a website using wordpress with all in one seo and xpml in 3 languages with their sitemaps
website.com/sitemap.xml (default in spanish) website.com/en/sitemap.xml (english version) website.com/pt-br/sitemap.xml
1.- First what is the best practice to put in the robot.txt,
to put just one line (website.com/sitemap.xml )
or the 3 sitemap url? (also the xpml plugin automatic add a rel="alternate" hreflang="x
in each page with the link to the translated page)
2.- for google webmaster tools what are the best practices?
submit the 3 sitemaps submit just 1 sitemap and hope google understand the translation with the use of rel="alternate" hreflang="x"
or Create 3 different accounts, 1 for each language?
