AI Translate


I made this plugin to be able to extend the websites I manage beyond the borders and it worked exceptionally good. Within a month 180% increase of organic search traffic and some sites had even bigger increase in organic social traffic. I hope everyone enjoys this plugin and give it a 5 star rating.
