Location Specific Traffic and Conversion

The scenario is, I am currently working on a market research website, which publishes the market reports. The task assigned to me is to drive the traffic and leads from United States. By doing some SEO activities i managed to drive the traffic but there is no significant change in leads from US. Can anyone share his views in this scenario?

For increasing the traffic of the people, first you should analysis your website and then do SEO after finding the quality website which is rising with the good DA.
