Have you ever started marketing but couldn't quite get a sense of whether it's working? You may post on social media every day and run ads, but it's bound to feel daunting without a standard to judge whether they are effective. Today, we have compiled four key metrics you absolutely must check so that small business owners can verify their marketing performance with numbers rather than intuition.

4 Key Indicators for Small Business Owners

First, Reach — How many people did it reach?

It is an indicator showing how many people have seen your content, similar to social media post impressions or website visitors. If reach is low, it means that no matter how good your content is, there are few people viewing it, so you should start by reviewing your channels or exposure methods.

Second, Conversion — Did it lead to actual action?

High reach is meaningless if it does not lead to inquiries, purchases, or reservations. The conversion rate, which is the percentage of visitors who actually take action, is the most direct indicator of whether your content or product page is persuading customers.

Third, Customer Acquisition Cost (CAC) — the cost of bringing in one person

If you divide this month's advertising and marketing expenses by the number of new customers, you will get the cost of acquiring one customer. If this cost is greater than the actual profit brought in by that one customer, then you are essentially engaging in marketing that yields no profit, no matter how much your sales increase.

Fourth, Repurchase Rate (Retention) — Are there customers who come back?

It is far more cost-effective to bring back existing customers than to acquire new ones. If the repurchase rate is low, you need to examine the post-purchase experience—specifically, whether there are any issues with service or after-sales support.

If you develop the habit of checking these four metrics just once a month, marketing will no longer be a matter of intuition but a strategy. Don't try to calculate everything perfectly from the start; begin by recording the numbers for one or two channels you are currently using.
