Sure, you can absolutely do that.
In order to try conversions tracking you can activate a 14 day trial of JotUrl (you can stop your trial on day one and it will last in any case for the whole 14days period).
You can create N tracking links (you can use to track views, clicks and conversions from different sources/channels) and add the same conversion code/pixel to them. You have just to copy and paste the conversion code/pixel within your thank-you-page (TYP) or within the page users are redirected immediately after they signup to your service.
Please copy the conversion code/pixel immediately before closing the "body" HTML tag.
You can find a tutorial about conversions at http://jo.my/joturl-conversion-tracking. You can also leverage S2S conversion tracking, via Postback URLs, using our integrated Postback URL builder.
