 conversion rate

A conversion is an action in a visit on your website that completes a certain goal. Depending on your page’s purpose, these goals can be:

  • Make a purchase
  • Add products to the cart
  • Proceed to checkout
  • Create an account
  • Request a trial version
  • Check out a demo
  • Subscribe to a newsletter
  • Volunteer personal information for something (personalized analytics, free documents, etc)
  • Talk to you via the chatbox
  • Download something (eBook, demo, etc)
  • Send a product request
  • Install something to use (demo, software trial, etc)
  • Submit a contact form

If you are running an e-commerce website, you may care about the final goal - a purchase. However, as a marketing manager or website owner, you cannot look only at a big picture, try to break down this “macro” goal into some “micro” goal and improve each one if needed. For example, you put a trial version of your service on the landing page, if the number of trial version request is high but the sales are low, you should revise the trial version’s quality.

  • Step 3: Use the following formula to count calculate the conversion rate: Conversion rate = The number of conversions/ The number of visitors * 100%

Noted: Because internet traffic has a lot of accidents that someone could randomly click on the link and be taken to your site. The only way to effectively calculate the conversion rate is to watch the rate for a time frame.

According to Statista, 21% of customers abandon the cart because of the long checkout process. And this reason is always in the 8-primary-reason list of cart abandonment.

E-commerce customers can spend a lot of time choosing their desired product but they are always in a hurry to finish the purchase once the shopping cart is filled in.

Also, there is a case that a customer goes back to the previous step in the checkout process happens frequently. During these steps, he/she has more time to consider the cart items, and the high chance that the checkout cannot be finished.

Thus, there is a useful tool to help you combine all steps to one step, which is One-step-checkout. This tool allows guest checkout without signing-up and increases the conversion rate dramatically. A statistic has shown that the one-step-checkout outperforms the multiple-steps-checkout by 21.8% and there is more potential to explore.

Increase traffic quality

The traffic quality is very important to the conversion rate. Visitors that you have drawn in cannot find their desired items because of the wrong demographic or behavior targeting tactics. If you can watch the customer behavior on your landing page and see that many of them leave, it may be because the buyer personas which describe your targeted customers are inadequate. Thus try to find your most potential customers.

  • Do market analysis carefully
  • Try different segments to shape the most suitable buyer personas.
  • Explore all marketing channels and select the most suitable ones for your segment to make sure your leads are high-quality.
