If you don't have a conversion "page", you can still track conversions with Spring Metrics. A common example of this is when a contact page form submission doesn't return the visitor to a thank-you page.

Usually the code for a button will be contained in between a <form> tag and a </form> tag. If you have access to edit the code for the button, change

 <form> 

into

 <form onsubmit="var f=this;setTimeout(function() { f.submit(); }, 750);_springMetq.push(['convert','conversionName']);return false">

Be sure to change conversionName into something that accurately captures the nature of the conversion. Contact support@springmetrics.com if you're having trouble setting this up.
