When you made something you want to know if it is useful or not so you would have to test it. When you buy a bulb you let it be tested because you want to make sure that what you are buying is working. It is not just in the bulb but in anything like television, cellphone, radio, kitchen appliances, washing machine and many more. Testing is important and you even demand a warranty because you want to make sure that it is not a waste.
That is why there is also the tracker of the websites that are designed and built so they could help websites and owners. There are already thousands and even millions of websites around the world and each of them strives to be at the top because it has a big impact or meaning. Many people who have a website like that people visit their site because it is that way that they can promote their product and distribute any information they want to let people know.
In this time also, there are the invented techniques to advertise online using the website. They need the tracking tool to see if what they are doing is successful. If it is generating a lead that can result in a sale or it is not a good tool. If it is just there and the owner does not have the tool to see if it is working then it can be tiring and many were just be wasted. But thankfully there are tools.
