It really varies depending on the products you offer. Average eCommerce conversion rates vary between 1% and 4% globally. If you have all the right pieces in your marketing mix, you’ll find yourself in the average sweet spot of 2%-2.5% conversion rate. In better case scenarios – and with more time and money invested in an eCommerce conversion rate optimisation program – your online store could see conversion rates for eCommerce as high as 3% or 4%.

To calculate the actual eCommerce conversion rate, you can calculate it based on Visitors or Visits:

Based on Visitors (or users): Dividing the number of conversions in a fixed period by the total number of people who reached your landing page or your homepage – and then multiply it by 100%:
eCommerce Conversion Rate = (conversions / total visitors) * 100%

Based on Visits:
eCommerce conversion rate = Number of Store Transactions/Number of Website Visits x 100

No, CRO does not affect your other marketing efforts. In fact, CRO enhances them.

For example, some marketers measure the success of performance marketing based on direct response and in-session revenue. Other marketers place more weight on a carefully defined lifetime customer value (LTV), which captures customer ROI over a period of months or years. Through continuous testing and learning, CRO helps organizations maximize both.

A conversion optimisation agency can have an amazing impact on your bottom line, but at the same time, you have to make sure that you have the budget to pay for that service. Typically CRO companies charge anywhere between $3,000- $6000 / month on the lower end, $8000 – $15,000 / month on the middle end, and $20,000 – $30,000 / month on the more expensive end. Of course this can depend on the nature and the length of the campaign.

But to find the right agency, you need to do your homework. When vetting CRO agencies, ask tough questions. Talk about processes, win rates, testing frameworks, team structures, costs and client referrals. You wont to find out how data-driven their research and testing process is.

“A good agency has already found the patterns of successful work,” said CRO expert Andre Morys, CEO and founder of konversionKRAFT. Morys continues: “And if you found these patterns, usually you build your own framework or methodology because success in CRO is not a result of trial and error. There are enough people who misuse A/B testing for trial and error. But what you want is a success that is based on a great methodology.”
