Simple guides on Amazon growth

ACOS and TACOS are two numbers every Amazon seller should know. They sound similar, but they tell you different things.

ACOS stands for Advertising Cost of Sale. It compares your ad spend to your ad sales. If you spend 1,000 rupees on ads and those ads bring in 5,000 rupees in sales, your ACOS is 20 percent. A lower ACOS usually means your ads are more efficient.

TACOS stands for Total Advertising Cost of Sale. It compares your total ad spend to your total sales, both from ads and from organic search. This number shows how much your whole business depends on paid traffic.

Here is why both matter. ACOS alone can look great while your business is still fully dependent on ads. TACOS tells you if your organic sales are growing too, which is a sign of a healthier, more stable brand.

• Track ACOS to judge if a single campaign is efficient.
• Track TACOS to judge the health of your whole Amazon business.
• A brand that is growing well usually sees TACOS go down over time, even if ACOS stays steady.

Launching on Amazon feels simple. List the product, turn on ads, and wait for sales. In practice, small mistakes early on can cost a brand months of wasted time and spend.

• Launching without a pricing plan. Price is often set once and never reviewed against fees, competitors or promotions.
• Weak product listings. Titles, images and bullet points are written quickly instead of being built around what shoppers actually search for.
• No target ACOS before ads go live. Campaigns start with a budget but no clear cost target, so spend is hard to control later.
• Ignoring reviews and ratings early on. The first few reviews shape how a listing performs for months. Many brands do not have a plan for this.
• Not tracking FBA and storage fees. These costs are easy to miss and can quietly turn a profitable looking product into a loss.

Most of these mistakes are avoidable with a clear plan before launch, not after.

Sales numbers are easy to celebrate. A brand can double its sales and still lose money if it is not watching unit economics.

Unit economics means looking at the profit on a single unit sold, after every real cost. This includes the product cost, Amazon referral fee, FBA fee, storage, ad spend and any returns.

Two brands can have the same monthly sales and completely different results. One is profitable and growing. The other is funding sales with ad spend it cannot sustain. The only way to tell the difference is by checking the numbers per unit, not just the total.

• Know your true cost per unit, not just the product cost.
• Check profit per unit before increasing ad spend, not after.
• Use this number to decide which products to push and which to fix or drop.
