Throughout the life of a website, there may be fluctuation in the conversion rates. If you aren't tracking them they may seem completely erratic. Why are my conversions suddenly up? Why are they suddenly down? However usually they aren't erratic at all and it's actually something you’re doing to cause the increase or decrease in conversions. This is why it's so important to gather information on where your leads and enquiries are coming from! When you get increases you need to know what worked so that you can replicate the experience and make the raised visits, the usual visits.
