Who is your target audience? When you know who you’re talking to, you can determine the best way to talk to and take care of them. When you immediately clarify who your website is for, you’re telling those ideal customers to pay attention. You’ve got something specifically for them.

Conversion rates often seem to operate parallel to social media efforts rather than actually intersecting with them. Social media does a great job increasing the quantity of leads, but what’s the point if the website itself doesn’t convert well?
Social Media is another aspect of web site promotion which must be considered and utilized to optimize a website for conversion. 
Identifying and interacting within the online communities populated by your potential customers is imperative to increase conversions. If you select the wrong target audience or join Online Communities which are not relevant to your product or services the effect Social Media has on your conversion rates will be zero. If powerful and targeted enough, social media campaigns will help increase your website’s conversion rate.
