You may invest a lot of effort into bringing users to your website — set up contextual advertising, create and promote useful content, run social media campaigns, — yet there will be no point in all these initiatives if your visitors don’t turn into customers or, in other words, don’t convert.

So, in this article, we’ll talk about sales conversion rate; in particular, we’ll define this notion, explain how to calculate conversion rate at each step of the customer journey, and offer some ways on how to improve your sales conversion rate with email marketing.

What is sales conversion rate?

Sales conversion rate is a metric, usually expressed in percentage, which shows what part of visitors who interacted with your company or your product made a purchase. For an eCommerce business, the sales conversion rate is a ratio of customers to website visitors. For example, a conversion rate of 2.5% means that 25 out of thousand website visitors made a purchase.

You might have already heard of such terms as micro conversions and macro conversions. A purchase is considered to be a macro conversion, while all other actions which lead to this purchase — email subscription or a price list request — are micro conversions.

How to calculate conversion rate and why online store owners need it

Track your metrics for a particular period of time, for instance, a month, and place them in a sales conversion rate formula:

Sales conversion rate = Customers / Visitors x 100

Google Analytics can automatically calculate your sales conversion rate. For that, you should set up eCommerce tracking to your website to collect data.

Two logical questions may arise, Why do other users don’t make a purchase? What should I do to optimize my conversion rate? To answer them both, you should better understand your customers’ behavior.

Conversion rate at different stages of the sales funnel

A sales funnel demonstrates how many users you lose from their very first visit of your website up to a purchase. In an online store, the sales funnel looks like this: a user visits a website, goes to a cart, opens up a purchase page, and clicks “Pay:”

If you go over each metric at each step of the sales funnel, you will see what can be improved. For example, if users leave at the purchase confirmation step, set up triggered emails and motivate users to finish up their purchase.

Conversion rate of first-time buyers and repeat customers

First-time visitor conversions show how well you can sell in general by bringing value to the audience, answering people’s questions, and helping users to solve their problems.

Repeat customer conversion rate demonstrates how valuable the product was for the buyers and how well your post-purchase strategy works.

Conversion rate of customer acquisition channels

This number shows which marketing channels bring more customers. By analyzing conversions of different acquisition channels, you can determine which of them were more or less effective.

How to boost sales conversion rate of an online store using email

Only a part of your website visitors will make a purchase right away. The rest will leave and probably won’t come back. However, if you continue communicating with visitors, try to allay their fears and overcome objections, they may become customers. Email marketing is a channel which suits perfectly for this task.

Below are a few tips on how to boost your sales conversion rate by getting visitors’ contact details and communicating with them through email.

Place several subscription forms on your website

To build a strong mailing list, add several types of subscription forms to different places of your website. For example, Anthropologie obtain their visitors’ contacts through two different subscription forms.

The first form is a delayed pop-up:

And the second one is an embedded form located in the footer of their website:

Create a lead magnet

To motivate users to sign up and share their contact details, offer a lead magnet. For online store visitors, a lead magnet can be anything from a discount to a free price calculation.

Kate Spade, for example, give out 15% discount and free shipping to all new subscribers.

Set up a welcome email

After you’ve motivated a user to sign up, it’s time to use this chance to greet them properly. For that, you should launch an automated welcome email.

A welcome email, or a welcome email series, is usually triggered right after subscription. It’s a perfect time to thank a subscriber for joining your mailing list, offer some discounts, tell more about your company, and provide a short guide on your product — if what you sell is a service or an app, for example.

Take a look at the example of such email from Creative Market.

The company thanks subscribers for opting in and offers a 10% discount available only for a week — fear of missing out can be a good motivator to make a purchase, you know.

Segment your audience

Mailing list segmentation is one of the most effective tactics in email marketing. It allows you to prepare personalized emails which bring value to various groups of users. The more relevant emails you send out, the more purchases users will make.

You can segment your audience by

  • demographic characteristics such as gender, age, occupation, and financial status;
  • user activity on your website and in emails;
  • purchase history;
  • customer lifecycle, and any other characteristics valuable for your business.

Post-purchase reviews, loyalty program registration, and email surveys are just some ways to build customer profiles and segment your email subscribers.

Another opportunity to segment your mailing list is to use a preference center. For example, TheRealReal allow users to specify how often they would like to get emails and which categories of goods they prefer.

Send out re-engagement emails

Monitor user behavior on your website or in emails to immediately react to activity decline. Re-engagement email campaigns will help you wake up “sleeping” subscribers. These can be users who joined a mailing list but didn’t purchase anything or those who used to purchase but then stopped. You should remind them about your company and give them a reason to buy.

For instance, Shutterstock send out re-engagement emails with a $10 discount to those who purchased the same image pack before.

Set up abandoned cart emails

A user who added an item to a cart and almost finished a purchase may suddenly change their mind — something could go wrong, say the price might seem too high, or something could simply distract them. To bring a potential customer back, send out abandoned cart email.

It can be a single email or a whole series of triggered abandoned cart emails, where you can

  • remind visitors about items left in the cart;
  • offer assistance;
  • give them a coupon or a discount as some motivation to make a purchase.

Depositphotos, for instance, remind users about the files left in a cart and encourage them to complete a purchase. Note that the CTA says “Check my cart,” and this message sounds more inviting than “Proceed with the purchase,” for example.

Send emails dedicated to a special date

Think of any important dates in the life of a customer you could dedicate your future emails to. Congratulate subscribers on their birthday, sign-up anniversary, or any other holidays by offering a gift. Statistics prove that conversion rate of special date emails are almost 5X higher than any other emails.

Take a look at the example from Denny’s. They send out happy birthday emails with an appetizing photo and invite to have a birthday breakfast at their restaurant.

Create a post-purchase email series

Provided a purchase was successful, post-purchase emails can help you maintain a solid reputation and encourage repeat purchases.

In a post-purchase email, you can

Leia store, for instance, thank users for purchasing a book and ask to rate the product right in the email.

To encourage users to purchase more, you can offer them some complementary products. For example, if a customer has recently purchased a phone, you can promote a phone case or earphones.

In their email, Dollar Shave Club, for example, not only notify a customer about the box shipment but also show the items that could fit in the next box.
