Ecommerce marketing agencies in India: the marketplace ad account, the 2026 listing rules and the brief to hand over

An ecommerce marketing agency in India does four jobs for an online seller: it runs the ads inside the marketplaces, mostly Amazon and Flipkart, it fixes the product listings those ads send shoppers to, it runs Google and Meta ads for your own store, and it reports sales against spend. Hire one that keeps every seller and ad account in your name, that knows the listing rules under the Consumer Protection (E-Commerce) Rules, 2020, including the amendment published in September 2026, and that reports from the same sales figures your accountant uses. Ask each agency, in writing, which of the four jobs it does itself and which it hands to someone else.

The four jobs behind one phrase

Sellers search for an "ecommerce marketing agency", an "Amazon marketing agency" or an "Amazon advertising agency" and get very different firms back.

Job	What the agency does	Ask it
Marketplace ads	Runs Sponsored Products and other ad types inside Amazon, and the ad tools other marketplaces offer, with bids, keywords and budgets	Which marketplaces have you run ads on this year, and can we see one account report?
Listings and catalogue	Titles, images, bullet points, product details, brand content and the compliance fields each listing needs	Who writes the listings, and who checks the legal fields before they go live?
Your own store	Google Ads, Shopping and Meta ads, email and WhatsApp, and the store pages they point at	Will the ad accounts and the store be in our name from day one?
Reporting	Sales against spend, by marketplace and by product, every week or month	Which sales figure do you use: gross order value, or what the marketplace actually pays us?

A brand selling only on Amazon may need just the first two jobs. A brand with its own store needs all four, ideally from one team. For how agencies outside India split this work, our guide to the four capability stacks of an ecommerce digital agency goes into each one.

What Amazon itself says about ads and service providers

Amazon Ads' India page on Sponsored Products, read on 22 October 2026, calls them "cost-per-click (CPC) ads that promote individual product listings on Amazon and select premium apps and websites". It says you choose the products and the keywords, or let Amazon's systems target keywords automatically, and that "You control how much you want to spend on bids and budgets". A click takes the shopper to the product detail page, so ads without a fixed listing spend money on a weak page.

Amazon also runs a Service Provider Network for sellers, inside Seller Central. Its India page, read the same day, lists the services sellers can find there, including imaging, cataloguing, account management, advertising optimisation, enhanced brand content, taxes and compliance. It says sellers can contact providers directly and add reviews. Treat it as a place to find candidates, not as a recommendation. Our page on comparing Amazon advertising and marketing agencies covers how the fee models change what an agency pushes you to do.

The listing rules an Indian agency has to know

The Consumer Protection (E-Commerce) Rules, 2020 set what marketplaces and sellers must show to buyers. The Department of Consumer Affairs published the Consumer Protection (E-Commerce) (Amendment) Rules, 2026 in September 2026, with a commencement date in January. Check the exact start date in the copy on consumeraffairs.gov.in. Four changes fall straight on marketing work.

Sponsored listings must be clearly marked

The amendment says every e-commerce entity "shall ensure that sponsored listing of products and services are distinctly identified with clear and prominent disclosures". It also adds to the list of things an entity must not do: mislead users "by manipulating search result or search indexes". Paid placements that look like organic results are what the rules forbid.

A discount has to show the prior price

Where an entity or seller announces a price reduction, it must show the prior price beside the reduced price, and the amendment defines the prior price as "the lowest price of a good or service thirty days prior to the announcement of price reduction". So a sale banner cannot compare against a price you raised last week, and your agency should check each sale against your price history first.

Seller details belong on the listing

The amended seller duties list the details a listing must carry for the buyer to decide before purchase: country of origin, best before or use before date, return, refund, exchange, warranty and guarantee, delivery and shipment, the cost of return shipping and modes of payment, and "any identification number issued by the Central Government including Goods and Services Tax Identification Number or Micro and Small Medium Enterprises registration number". For imported goods, the entity must name the importer and the country of origin "as provided under the Legal Metrology (Packaged Commodities) Rules, 2011". An agency rewriting listings must keep these fields complete.

Dark patterns and grievances

The amendment requires every e-commerce entity to comply with the Guidelines for Prevention and Regulation of Dark Patterns, 2023 and to run a yearly self audit. It also says the grievance officer must acknowledge a consumer complaint within 48 hours and redress it within one month. Ask the agency which of its sale and checkout tactics it has checked against those guidelines.

The GST line in marketplace sales

Marketplaces collect tax at source (TCS) under GST on the sales sellers make through them, and file it in a return called GSTR-8. The GST portal's GSTR-8 manual, read on 22 October 2026, says the operator declares TCS supplier by supplier against each supplier's GSTIN, that "Tax is to be collected on the net value of supplies", and that from the July 2024 tax period the total TCS must be between 0.5% and 1% of the net amount, against exactly 1% for earlier periods.

For marketing, this matters in one place: the sales figure. A marketplace payout has commission, fees, returns and TCS taken out of it, so the order value in an ad report and the money that reaches your bank are different numbers. Ask the agency to report net sales beside gross order value, on the same basis your accountant reconciles.

The brief to hand an ecommerce marketing agency

1. Your channels. Which marketplaces you sell on, whether you have your own store, and what share of sales each brings.
2. Margin by product. What you can spend in ads to sell one unit of each main product and still make money. This is the only honest basis for a budget.
3. Account ownership. Seller Central, the marketplace ad consoles, Google Ads, Meta Business, the store and the domain all stay in your business name, with the agency given user access, not ownership.
4. The listing checklist. The legal fields above, your brand terms and the claims you can prove, so nothing is cut or overstated when listings are rewritten.
5. Sale calendar. Your planned sale events and your price history, so prior price display can be checked before each one.
6. Creators, if any. The Advertising Standards Council of India says on its influencer resource page that brands and influencers must disclose material connections. Write the label into each creator agreement.

How the work is priced, and what to compare

Agencies usually charge a percentage of ad spend, a flat monthly fee, or a fixed fee per listing or per batch of listings,. A percentage of spend rewards a bigger budget, so pair it with a target for sales against spend. When you compare quotes, ask each agency to separate its own fee from the ad money that goes to Amazon, Flipkart, Google or Meta, to name the person running your account, and to list what is outside the fee, such as photography, A+ or brand content, creator fees and GST.

Questions sellers ask about ecommerce marketing agencies in India

Should one agency run Amazon, Flipkart and our own store?

Often yes, if it has a named person for each and reports them side by side, so your store ads and marketplace ads do not chase the same shopper.

Who should own the seller and ad accounts?

You should. Keep Seller Central, every ad console, Google Ads, Meta Business and the store domain in your business name, and give the agency user access. If you change agency, you keep the history.

Does the agency need to know the e-commerce rules?

Yes, because its work touches the parts the rules cover: sponsored listings, sale prices, listing details and store checkout design. Ask it to show you how it checks a sale campaign against the prior price rule before launch.

When can we judge whether the agency is working?

Read three things each month: ad spend against attributed sales in each marketplace ad console, sales and conversion on the product pages the agency rewrote, and the net payout from each marketplace. The outcome depends on your products, your prices, the competition in each category and your budget, so judge the agency on the work it agreed to deliver and on those numbers, not on impressions.

When a shopper asks an assistant before the marketplace

Some Indian shoppers now ask ChatGPT or Gemini which brand of mixer grinder, sunscreen or school bag to buy before they open a marketplace app, and the reply names a few brands. Those names come from reviews, comparison articles and the brands' own pages more than from any ad. Our page on AI visibility for Indian ecommerce brands covers that side. AI Knows Us is part of this newer category: it asks those buyer questions on ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews and shows which brands come back, and which sources each answer leaned on.
