Welcome to the Q&A Forum

Hi David, When using hreflang, you must always specify a language and a country. In your example hreflang="en"  and hreflang="es" are not valid because they don't specify a country to go with the language. If you are targeting the US for both languages, you would need to use hreflang="en-us" and hreflang="es-us". Aleyda Solis has a great hreflang generator tool if you get stuck: http://www.aleydasolis.com/en/international-seo-tools/hreflang-tags-generator/ Cheers, David

Yes, it's correct!

These kinds of named anchor links have no effect on SEO, fortunately. Google crawlers ignore the anchor variable altogether. Make sure you have correct canonical tags on each page just for extra insurance. Paul

Hi David, Good question! When you are logged into Moz.com, if you click on your user avatar in the top, righthand part of the main site nav, you will see a link to your private messages. (I've called it out with a hot pink box in the attached screenshot.) E6PZR
