The GTS Translation plugin provides human quality translation by allowing you to combine automatic translation and human post-editing (crowdsourcing). Your blog content is initially translated by our translation server. The content is then post-edited by human translators through our online editing system. You can use the GTS community of translators, or you can assign the post-editing to your own community of translators to maintain complete control of the process.

When you use the GTS Translation plugin, translated content is cached in your WordPress database and indexed by search engines. This will increase the traffic to your website and grow your international readership.
