Hreflang tags are necessary to help search engines understand the language of a particular web page and who to serve it to. They’re notoriously hard to implement (unless you’re a developer)…luckily, Weglot adds these for you!
It’s not just visible website copy that Weglot translates. Key SEO text such as your metadata or image alt tags are also detected and translated. You can then choose to edit those translations to target more specific keywords in your new markets.
