The page is missing meta language information.

Hi,

I saw my website have a problem about meta language, I do some search and found that I need to add  on the , with 'll' is language code and 'cc' is country code.

But I am confused what should I do, because my website is world wide, not launch at specific any language and country. Please give me an advice in this case.

Thanks,

Then you shouldn't add any meta. That tag is used to specified that your site is either targeting a specific Language and/or Country. As you aren't, there's no need to use the tag.

You should safely ignore and remove Meta Language Tag.

Meta Language basically, gives instruction to browser that the page should only be displayed in the language as prescribed. In absence of this tag, if a visitor of other country, having different language visits the site, Google browser provides a translation of page so that the user can aptly view the details
