The decision to make a website available in many languages gives you the chance to reach out globally to clients that other businesses will not be able to accommodate effectively. With the simple fact that you have stepped beyond your usual territory, it is easier to claim success in increasing the chances of having the kind of diversity that you need to grow. It shows how eager you are to take the extra mile to stretch out all the possibilities, taking away the limitations that most websites set in terms of readership and following.
As I have helped small businesses blossom with these methods, my recommendation to always make a website available in many languages stems from experience and real results. Simple as it may seem, it takes you a step nearer to your goals, showing that you are the sort of business intent on building diverse and lasting global relationships.
