WPML makes it easy to run a multi-language site from a single instance of WordPress. WMPL supports more than 40 languages as well is customizable to allow for variants on languages. This will allow you to increase your audience reach as well open up additional organic search results that would not be available with a single language site. In most cases the plugin can be easily installed and managed with little to no assistance, but with the number of themes both custom and premium there are cases where assistance from an expert can be beneficial. I have been working as a custom WordPress developer and WPML for the past 5 years and provide my client both technical as well as business assistance to increase both traffic and conversions to their websites.
