2. Estimate the value of your site

What is it?

Estimating the value of your site consists in carrying out an indicative evaluation of what your online store would be worth if you decided to sell it. This calculation integrates various parameters: traffic, profitability, sales history, customer base, etc.

Why is it important?

• Preparing for resale : Knowing the value of your site can be useful if you want to raise funds or sell your business.
• Negotiation argument : Faced with partners or investors, having a credible estimate of the value of your store provides a solid basis for discussion.

3. LTV (Lifetime Value) - Customer lifetime value

What is it?

La LTV (Lifetime Value) represents the total value that a customer spends with you for the duration of their “relationship” with your brand.

Why is it important?

• Loyalty strategy : Knowing the LTV allows you to determine how much you can spend on acquisitions to make a new customer profitable.
• Revenue forecast : Anticipate how much each customer can bring in over time.
• Optimizing the customer experience : A good understanding of LTV encourages the deployment of actions to increase satisfaction and the recurrence of purchases.

By entering your recurring sales data and the average length of customer loyalty, you get an accurate estimate of customer lifetime value. You can then adjust your marketing budgets and loyalty offers to maximize long-term profitability.

4. Average revenue per user (ARPU)

What is it?

The Average Revenue per User (ARPU) is the average amount generated by each unique visitor or customer over a given period of time.

Why is it important?

• Segmentation and targeting : Identify whether certain customer segments generate a higher ARPU than others.
• Marketing optimization : Better allocate your advertising budgets by focusing on the channels that offer the best ARPU.

5. Advertising and Acquisition

The importance of evaluating your advertising costs

Online advertising (Facebook Ads, Google Ads, Google Ads, TikTok Ads, etc.) is often a pillar of the acquisition strategy. Knowing how much you spend to acquire a customer or generate a click is crucial to optimize your profitability.

5.1 Cost per Acquisition (CPA)

Our tool takes into account your advertising budget and the total number of clicks generated to provide you with an average CPC. So you can adjust your ads, keywords, and audiences to optimize it.

5.3 ROAS simulator

What is it?

The ROAS (Return On Ad Spend) measures the revenue generated for each euro spent on advertising. For example, an ROAS of 5 means that for €1 invested, you get €5 in sales.

Why is it important?

• Performance management : ROAS is a key indicator for evaluating the success of your advertising campaigns.
• Budget allocation : Knowing your ROAS allows you to determine which channels you should invest in first.
• Optimizing margins : A low ROAS indicates that you probably need to optimize your costs, rethink your ads, or target more qualified traffic.

Thanks to our simulator, you can test different scenarios (budget increase, CPC change, etc.) and observe how the ROAS varies. You thus identify the most suitable strategy to maximize your sales.

6. Medium basket

What is it?

The Medium basket represents the average spend of your customers when ordering. For example, if you have 100 orders for a total of 2000€, your average basket is 20€.

6.1 Average Order by Traffic Source

Why is it essential?

Not all traffic sources are the same: visitors coming from a Facebook ad will not behave the same as those who come from an email campaign. Knowing the average basket by traffic source allows you to prioritize the most efficient channels.

How does it work?

Our tool segments your turnover and your order volume according to each channel (Facebook Ads, Google Ads, organic traffic, e-mailing, etc.). This will allow you to detect which channels have the highest average value and invest more in them.

6.2 Upsell and Cross-Sell Rates

What is it?

• Upsell : Offer the customer a higher or more expensive version of what they are already buying (e.g. a premium product or a larger volume).
• Cross-sell : Offer complementary products (e.g. a case for a smartphone).

Why is it important?

• Increase the average basket : These techniques make it possible to boost the value of each order.
• Customer Loyalty : Suggesting useful complementary products improves customer satisfaction.
• Profitability : By optimizing upsell and cross-sell, you maximize the profitability of each order.

How does our calculator help you?

By integrating the number of sales made through upsell or cross-sell, and the total number of orders, our tool shows you a precise percentage to assess the effectiveness of your strategies.

6.3 Coupon usage rate

What is it?

• Segmentation and loyalty : Coupon users can represent a specific segment that is interesting to target (or not) in a different way.

How does our calculator help you?

By entering the total number of orders and the number of orders that took advantage of a coupon, you get a usage rate. This gives you a clear vision of the relevance and profitability of your promo codes.

6.4 Average number of products per order

What is it?

This is the ratio that measures how many products are purchased in a single order.

Why is it important?

• Merchandising strategy : A high average number may indicate that your catalog is relevant and that your product recommendations are working.
• Logistics costs : The more products the order contains, the more you need to optimize your packaging and shipping costs.
• Cross-selling effectiveness : A high average number can also reflect a good promotion of complementary products.

How does our calculator help you?

It automatically calculates this ratio based on the total products sold and the number of orders. You can thus refine your strategy of bundling or cross-promotions.

6.5 Average Cart Value (AOV)

What is it?

AOV (Average Order Value) is simply the English equivalent of the average order value. This is often the term used in e-commerce dashboards or advertising platforms.

Why is it important?

• International comparison : If you sell abroad or work with English speaking partners, this is a very common term.
• Essential KPI : AOV is one of the basic KPIs to follow on a daily basis to assess the health of your e-commerce.

How does our calculator help you?

In the same way as for the average basket, you enter your turnover and your order volume. You then get your AOV for a clear and quick vision of your situation.

7. Conversion

7.1 Click-through Rate (CTR)

Why is it important?

• Quality of your visuals/hooks : A high CTR indicates that your ads or emails are engaging and click-through.
• Effectiveness of the campaign : A low CTR may mean that you are reaching the wrong audience or that your message is not relevant.
• Advertising cost : On some platforms, a high CTR can reduce your CPC and improve your positioning.

How does our calculator help you?

By entering the number of views and clicks obtained, you will immediately know if your campaigns are performing well. You can then refine your content, titles, or targeting.

7.2 Checkout abandonment rate

What is it?

This is the percentage of customers who leave your site without completing their purchase after starting the payment process.

Why is it important?

• Direct impact on turnover : A high dropout rate is a considerable loss of profit.
• User experience : Often linked to an order process that is too long or too complicated.
• Recovery strategy : Set up email or SMS reminder campaigns to recover these potential sales.

How does our calculator help you?

By entering the number of visitors who started the checkout and those who finalized it, you get an abandonment percentage. You can then take corrective actions, such as simplifying your sales funnel.

7.3 Add to cart rate

What is it?

The Add to cart rate is the percentage of visitors who add a product to their cart compared to the total number of visitors.

Why is it important?

• Relevance of the offer : A high rate indicates that visitors are interested in your products.
• Optimization of the product sheet : Are the visuals, descriptions, and prices convincing enough?
• First step to conversion : A good rate of addition to the cart is a positive indicator, but you still need to turn the test into a sale.

How does our calculator help you?

By recording the total number of visitors and the number of basket entries, you get your addition rate. You can then test different optimizations (photos, videos, customer reviews, etc.) to improve it.

7.4 Conversion rate by acquisition channel

What is it?

The Conversion rate by acquisition channel Shows you, for each traffic source (organic, Google Ads, Google Ads, Facebook Ads, Facebook Ads, affiliate, email, etc.), the proportion of visitors who make a purchase.

Why is it important?

• Granular analysis : Not all channels convert the same way.
• Marketing budget : Focus your investments on channels that offer the best conversion rate or the lowest CPA.
• Multi-channel strategy : Adapt your message and your offer according to each channel to maximize conversion.

How does our calculator help you?

All you need to do is segment your data by channel: number of visitors from each source and number of purchases made. Our tool then calculates the specific conversion rate. You identify channels with high potential and those that require improvement or repositioning.
