I have optimized my site according to mobile devices consulted an expert to make the right way. And also using facebook sponsored ads to catch leads. But still no leads from mobile devices, I am getting from non-mobile devices but none from mobile. What should I do??
What is your site actually about? It sometimes happens that the site may be mobile optimized but the main stream of customers lies in the desktop so the conversions are from non-mobile devices only.
If you have a GA account you can determine why your mobile site doesn't convert because the visitors behavior will be monitored and the pages will be improved and make action from the users.
Track your mobile data analytics, engagement rate etc. I am sure you will find something. Share some extra information with us so we can help you for good.
