If you use Google Analytics and you're trying to increase the conversions on your website, keep reading. This article will show you how to set up conversion tracking using this service, which is a good first step.
A site's conversion rate is defined as the number of successful transactions divided by the number of total unique visitors. A "successful transaction" is a broad measurement; for an e-commerce website, this could mean a sale, so the conversion rate formula would be the number of sales divided by the total number of unique visitors.
Any webmaster can measure the conversion rate of their website using Google Analytics. This comprises an advanced use of Google Analytics, and is not common to the majority of Google Analytics users.
If you have a clearly defined "successful transaction" in your website, whether it is the number of downloads, number of sales, number of sign-ups, etc. then this article will help you set up Google Analytics to measure your website's conversion rate.
Requirements for setting up conversion rate measurement
Before you can use Google Analytics to measure your site's conversion rate, you need to meet a couple of important requirements. First, you need to have a clear transaction funnel that defines "success." This means that you can identify all possibilities in the flow of transaction from the moment a visitor enters your website all the way down to concluding a "successful transaction."
For example, if you define "successful transaction" as those visitors that submit the contact form, then a random sample of successful paths could include:
First possible path: Home page -> Contact form -> Success page (user lands on the home page, then goes to the contact form, fills it in, submits it, and is presented with a success page).
Second possible path: Home page -> Page X -> Contact form -> Success page (user lands on the home page, visits Page X, then goes to the contact form to submit an inquiry).
Third possible path: Contact form -> Success page (user lands directly on the contact form, maybe coming from search engines or direct traffic).
Now, which you do think defines the "true" successful path of your visitors to complete conversion? Well, it depends on your plan. If you need to measure the quality of your home page content (like how convincing/trustworthy the content is to visitors), then you can require visitors to read/pass the home page first, before submitting any inquiries to you via contact form. In that case, if they land on page x -> contact form -> success page, then it's not considered a true conversion, since it fails to pass by the home page. Your true conversion path in this case should be home page -> contact form -> success page.
The good thing is that Google Analytics can be set up to define the necessary steps that distinguish a "true conversion." What you will need to do, however, is sit down and decide which route you want to define as a true path to visitor conversion in your own website.
The second thing you will need to measure conversions with Google Analytics is a Google account. In fact, if you do not have a Google account, you need to have one before you can use Google Analytics.
The third thing you will need is a success URL that is different from the rest of the URLs on your site. This is a tricky but important requirement. The success URL needs to be entirely different from the URLs in the previous steps. For example, the one in step three will work fine:
But this one is not recommended, as this requires a pretty complex setup:
Step 1: www.somewebsite.com
Step 2: www.somewebsite.com/contactform
Step 3: www.somewebsite.com/contactform#success
All of the above URLs with anchors are not okay, as Google treats them as the same page and not an entirely different URL.
Finally, you will need embedded Google Analytics code. Google cannot track the conversion rate on pages which do not have the embedded Google Analytics code. So if you have a website with Google Analytics installed, it is important to make sure that there is Google Analytics code embedded on pages on which you will need to track conversion.
