There are many benefits to having a multilingual website. Perhaps the most obvious benefit is that it allows you to reach a wider audience. If your website is only in English, you're excluding a huge portion of the internet population. By adding other languages, you can open up your site to a whole new group of potential customers or readers.
Another benefit is that it can help you rank higher in search engines. If you have a multilingual website, you can target keywords in multiple languages. This can give you a big boost in the search engine rankings, making it easier for people to find your site.
Finally, a multilingual website can make you look more professional and credible. If you have a website that's available in multiple languages, it shows that you're a serious business that's willing to go the extra mile to accommodate your users. This can give you a big advantage over your competition.
As an example, take a look at Everything Hand Dryers. This site that we've just built is in English and German. Selling to countries in the EU got a whole lot harder thanks to Brexit so making the effort to speak your customers' language will make you stand out.
It's worth noting at this stage that we build most of our sites on the award winning Joomla content management system which is multilingual out of the box. BUT do not think that a google machine translation will be good enough. Always get your text translated by a native speaker because context is everything. I heard a great example on the radio just yesterday about the term Wines And Spirits being translated from english to welsh into the equivalent of wines and ghosts!
And finally, if you're in tourism and hospitality in the UK, take advantage of re-opening borders and encourage visitors from overseas in a manner that's sure to be appreciated.
