Amazon Ads Guide for Indian Sellers (2026): Sponsored Products, Bidding, Budgets in Rupees, ACoS and Campaign Structure

Amazon advertising is where most Indian sellers either build a brand or quietly lose their margin. The mechanics are not complicated, but the defaults are set to spend your money, and the metrics are easy to misread. This guide covers the three self-service ad types on Amazon.in, how auto and manual targeting differ, what the match types and bidding controls actually do, how much to budget in rupees, how to calculate ACoS, TACoS and ROAS with a worked example, and how to structure campaigns so you can see what is working. It ends with an honest view on when to use software and when to hire an agency.

Amazon's own help and library pages are the primary source for how the tools work. Cost figures for India are not published by Amazon; where we quote rupee ranges they come from 2026 industry reports and are marked as such. Checked 24 September 2026.

What ad types can an Indian seller run on Amazon.in?

Amazon DSP, the programmatic product, needs a minimum monthly spend that runs into lakhs and is bought through Amazon or an agency; it is out of scope for most sellers here. If you are not yet in Brand Registry, Sponsored Products is all you have, and it is enough to start.

Should you run automatic or manual campaigns?

Both, auto first. An automatic Sponsored Products campaign lets Amazon match your ad to searches and products based on your listing content. It needs no keywords, so it is the fastest way to find out which search terms convert for your ASIN. Amazon offers four auto match groups: close match, loose match, substitutes and complements. You can bid on each separately; most sellers run close match and substitutes higher and loose and complements lower.

A manual campaign is where you decide what to target. Keyword targeting lets you bid on specific search terms; product targeting lets you bid to appear on specific ASINs or whole categories, optionally filtered by price band, rating and Prime eligibility. Manual campaigns are where profit is made, because you control the bid per term.

The standard loop is: run auto for two to four weeks, pull the search term report, move converting terms into manual campaigns at the right match type, and add the non-converting terms as negatives in the auto campaign so it keeps hunting for new ones. Never let the auto campaign be your only campaign for more than a month.

What do the keyword match types mean?

• Broad match. Your ad can show for searches that include your keyword's words in any order, plus close variants and, in Amazon's current definition, related terms. Widest reach, least control.
• Phrase match. The search must contain your keyword phrase in that word order, with words allowed before or after. "cotton kurta" matches "women cotton kurta set" but not "kurta cotton women".
• Exact match. The search must be the keyword or a close variant such as a plural. Tightest control, highest conversion, smallest volume.
• Negative phrase and negative exact. Block searches that contain, or exactly equal, a term. Negatives are how you stop paying for "free", "used", competitor brand names you cannot convert, and sizes or colours you do not stock.

A workable pattern is to put a converting term in exact match in one campaign, in phrase match in another at a lower bid, and negative-exact it in the phrase and broad campaigns so each search is served by one bid. That is what people mean by a tiered or funnel structure.

How do bidding strategies and placement adjustments work?

Amazon offers three campaign bidding strategies for Sponsored Products. Dynamic bids, down only lowers your bid in real time when Amazon thinks a click is less likely to convert; it never raises it. Dynamic bids, up and down raises or lowers the bid based on the same signal; Amazon's guide states it "will increase or decrease your bids by up to 100% for all placements based on performance", so a Rs 10 bid can be pushed to Rs 20. Fixed bids uses your exact bid regardless of likelihood to convert.

Separately, adjust bids by placement lets you add a percentage on top of your base bid for three placements: top of search (first page), rest of search, and product pages. The adjustment can go up to 900%. The two controls stack. With a Rs 10 base bid, a 900% top-of-search adjustment and up-and-down bidding, the theoretical maximum is Rs 10 x 10 x 2 = Rs 200 per click. Few sellers mean to bid Rs 200 on a Rs 499 product, which is why we set placement adjustments only after the placement report shows top of search converting better than the rest.

Amazon shows a suggested bid and bid range for each target, drawn from recent winning bids for similar ads. Treat the suggested bid as a ceiling for a new campaign, not a floor. Start below it on unproven terms and let the search term report tell you where to raise.

How much should an Indian seller budget?

Amazon does not publish average CPCs for India. Two 2026 industry reports we read give a consistent picture. eVanik's Sponsored Products guide puts median CPCs at Rs 7 for books, Rs 9 for grocery, Rs 12 for home and kitchen, Rs 14 for electronics accessories, Rs 16 for apparel and Rs 19 for beauty, with top-of-search commanding an 18% to 40% premium. upGrowth's April 2026 pricing guide gives wider ranges for Sponsored Products by category (Rs 6 to Rs 18 for grocery, Rs 10 to Rs 40 for fashion, Rs 25 to Rs 80 for beauty, Rs 50 to Rs 150 and above for supplements), Rs 25 to Rs 80 for Sponsored Brands and Rs 4 to Rs 20 for Sponsored Display. These are agency observations, not Amazon figures, and your category and competition will differ.

The reason to think in clicks is that a keyword needs roughly 10 to 15 clicks before you can say whether it converts. At Rs 15 a click that is Rs 150 to Rs 225 per keyword per test. A Rs 300 daily budget spread over 30 keywords never learns anything.

Remember that ad spend is charged on top of Amazon's referral, closing and shipping fees; read our Amazon seller fees guide and work out your margin after those fees before you set an ACoS target.

How do you calculate ACoS, TACoS and ROAS?

Amazon defines advertising cost of sales as "ACOS = (ad spend / ad revenue) x 100" and notes that "ROAS = ad revenue / ad spend", so a 50% ACoS is a ROAS of 2. Amazon's guide is blunt about the threshold: "In order to maintain a profit, your Amazon ACOS needs to be lower than your profit margin."

• ACoS = ad spend / sales attributed to ads x 100. Measures the efficiency of the ads themselves.
• Break-even ACoS = your margin after product cost and all Amazon fees, as a percentage of selling price. Any ACoS below this is profitable on the advertised sale.
• TACoS = ad spend / total sales (ads plus organic) x 100. Falling TACoS while spend is flat means ads are lifting organic rank; rising TACoS means you are buying sales you used to get free.
• ROAS = ad sales / ad spend. The same information as ACoS, inverted. A 25% ACoS is a 4x ROAS.

Worked example: a Rs 799 product

Assumptions: selling price Rs 799, product cost Rs 250, Amazon fees (referral, closing, shipping, GST on fees) Rs 180, so margin before ads is Rs 369, or 46.2% of price. That is the break-even ACoS. One month's campaign: Rs 18,000 spend, 1,200 clicks at a Rs 15 average CPC, 96 orders from ads (an 8% conversion rate), and another 140 organic orders.

At 23.5% ACoS against a 46.2% break-even, every advertised order still makes Rs 181.50. If the conversion rate had been 4% instead of 8%, ACoS would be 47% and the campaign would lose money on every ad order, which is the usual story behind "Amazon ads do not work for us". Fix the listing (images, price, reviews) before you fix the bids.

How should you structure campaigns?

Keep it boring and readable. One structure that works:

1. Auto campaign per product group, four match groups bid separately, budget 10% to 20% of total. Its job is discovery.
2. Manual exact campaign holding proven keywords, highest bids, 40% to 60% of budget. Its job is profit.
3. Manual phrase or broad campaign with the same seed terms at lower bids, 15% to 25% of budget. Its job is expansion; harvest from it into exact.
4. Product targeting campaign on competitor ASINs and your own category, 10% to 20%. Its job is defending and conquesting detail pages.
5. Brand defence (Sponsored Brands and an exact campaign on your brand name) once you have Brand Registry.

Name campaigns so a stranger can read them: "SP | Kurta Set | Exact | Sep26". Use portfolios to group by product line. Keep one ASIN or one tight variation family per ad group, so search term reports map cleanly to listings. Review search terms weekly, bids fortnightly, structure quarterly.

What are the common mistakes?

• Running only an auto campaign for months and calling the result "Amazon ads".
• Bidding on suggested bids with up-and-down bidding and a top-of-search adjustment from day one.
• No negatives, so the same irrelevant terms are paid for every week.
• Advertising listings with fewer than ten reviews, a poor main image or a price above the category norm; clicks convert poorly and ACoS blows out.
• Judging ACoS daily. Amazon's attribution window is up to 14 days for Sponsored Products, so this week's spend is matched to sales that arrive later.
• Letting campaigns run out of budget by noon; the sales you miss are evening sales, which often convert best.
• Ignoring account health; a listing suppressed for a policy issue cannot be advertised, whatever the bid. See our Amazon account health guide.
• Pausing everything during a festival sale because ACoS rises; conversion rates rise too, and organic rank earned in that week carries into the next quarter.

Should you use software or an agency?

Three honest options. Do it yourself works up to about 20 ASINs and Rs 30,000 a month if someone in the business gives it two hours a week. Software automates bid changes, negatives and harvesting on rules; our sister product BlooprintAI covers Amazon India and UAE ads at Rs 14,999 a month with a 7-day trial, and Flipkart and Shopsy ads at Rs 12,999 a month. It suits sellers who understand the structure above and want the hours back. An agency makes sense when ads are one part of a bigger problem: listings, pricing, inventory and account health all need attention, or spend is large enough that a 5-point ACoS improvement pays the fee several times over. Industry pricing for Indian agencies in 2026 runs from about Rs 15,000 a month for a freelancer to Rs 1.5 lakh or more for a full-service team, per upGrowth's survey.

Whichever you pick, own your ad account (our ads management clients keep theirs). Campaigns should sit in your Seller Central login with the agency or tool added as a user, so the history stays with you if you change providers.

FAQ

What is a good ACoS on Amazon India? The one below your break-even margin. Industry benchmarks for 2026 cluster around 15% to 30% for established products, with launches accepting 30% to 45%. A "good" 20% ACoS still loses money if your margin after Amazon fees is 15%.

How much do Amazon ads cost per click in India? Amazon does not publish it. 2026 agency data puts most Sponsored Products clicks between Rs 6 and Rs 40, with beauty, baby and supplements higher, and top-of-search placements 18% to 40% above the median.

What is the minimum budget for Amazon ads? Amazon sets a very low daily minimum, but in practice Rs 500 a day is the least that produces enough clicks to learn from, and Rs 1,000 a day funds a full campaign structure.

What is the difference between ACoS and TACoS? ACoS divides ad spend by sales from ads. TACoS divides ad spend by all sales including organic. TACoS is the better long-term health measure because it shows whether ads are building rank or replacing free sales.

Can I run Sponsored Brands without Brand Registry? No. Sponsored Brands and Sponsored Display need an enrolled brand. Sponsored Products is open to any professional seller.

Does GST apply to Amazon ad spend? Yes, Amazon invoices advertising as a service with 18% GST, which a GST-registered seller can claim as input credit. Budget the gross amount for cash flow.
