Why creating a multilingual website is best for your audience.
Loads of people put up websites in hopes of making it rich online, but a lot of those people forget one simple thing. They don't make their site multilingual or translatable for their visitors.
Giving your users the option of converting your text into their native language will not only help your bounce rate but it will increase your sales exponentially. Your bounce rate will see some love because the amount of people coming to your website will not leave as quickly if your text has the option of switching to their own language. They don't leave right away because they can actually read what is written on you pages
You can increase your sales exponentially if you have content that converts to the users language because they can read your content. Let's say you have 1,000 people come to your website, they all probably won't be able to read what your website says, so if you have an option in the header/top menu that allows them to manually convert the text, they will treat you well by opening their wallets and hitting that "Buy Now" button
If you want to get really tricky, you can have a script programmed that recognizes the users IP address and alters the text to show the proper language You can see this happen when you are using a VPN and setting your IP to be from a different country, preferably one that does not speak English, and then go do a basic search on Google. The results will be based off of that type of language until you do another search in English. There are actually a lot of websites that have something like this programmed and you could probably find a pre written script that will allow your website to do the same. I don't think this would be expensive because it would basically be a script to recognize your IP and switch to specific files in your language files so that showed and not the standard English (or whatever you have it set to )
In the end, having your system recognize the IP of the user and switch the language or giving users the option to switch it manually will increase your sales It probably won't double or triple your sales, but you'll get a few more in the long run
