What is a Good HREFLANG Tags Generator?
And more importantly…
Do We Need to Have HREFLANG Tags on our Websites?
In this post, I’ll answer these questions and more. Hreflang tags are something every webmaster needs to understand – even if you decide not to use them yourself.
Hreflang tags (pronounced aitch-ref-lang) are a Google initiative. They were developed in 2011, and intended to advise Google when websites have identical or similar articles aimed at visitors in alternate languages.
It makes sense then, that Google would want us to implement them whenever and wherever appropriate.

If you write posts or page articles that are directed exclusively towards one audience, eg. en-us for English speakers living in the USA, then you needn’t bother with hreflang at all. This would also apply if your site wasn’t directed at any specific zone, and only written in one language. Search engines are perfectly capable of working out what language your website is written in.

However, if your site has articles with similar content written in various languages or dialects, you should be using these indicators.
