Google Shopping has a free listings program. Not discounted. Not a trial. Free. Permanently.
When someone searches Google for "best personal finance books 2026" or "new construction vs resale home book," your book can appear in the Shopping tab results with a cover image, price, and a direct link to your Amazon listing. You do not need an e-commerce store. You do not need to process payments. You need a Google Merchant Center account, a product feed with your book information, and about 45 minutes.
Google launched free product listings in 2020 as a response to Amazon's dominance in product search. The goal was to make Google Shopping a comprehensive product discovery platform by removing the cost barrier for merchants. For authors, this created an opportunity that almost no one is using: free product placement on the world's largest search engine, specifically in the Shopping tab where purchase intent is highest.
I listed all six books in our catalog through Google Merchant Center. Here is the complete setup process, the workarounds for books without a traditional store, and what the results look like.
How Google Merchant Center Works
Google Merchant Center is the platform where businesses submit product data for display across Google surfaces — Shopping tab, Google Search, Google Images, and Google Lens. Traditionally, appearing in Google Shopping required running paid Shopping ads through Google Ads. Since 2020, Google has offered free listings alongside paid ads, giving products organic visibility in Shopping results without any ad spend.
Free listings appear in the Shopping tab when a user's search matches your product data. They look identical to paid listings — product image, title, price, and merchant name — except they appear in the "organic" section of the Shopping tab rather than the "sponsored" section at the top.
For books, this is a direct competitor to Amazon's stranglehold on product discovery. A reader searching Google for your book's topic can discover and purchase your book through a Google Shopping result that links directly to your Amazon listing — bypassing Amazon's own search results page entirely.
Setting Up Merchant Center for Books
Step 1: Create a Google Merchant Center Account
Go to merchants.google.com and sign in with your Google account. The setup wizard will ask for your business name, country, and website URL. Use your author website (e.g., jwatte.com) as the business website. Verify ownership through Google Search Console or by adding a meta tag to your site.
Step 2: Configure Your Product Feed
Google Merchant Center requires a product feed — a structured data file that describes your products. For books, the critical fields are:
- id — A unique identifier for each book (use the ISBN or Amazon ASIN)
- title — The book title, exactly as it appears on the cover
- description — The book description (use your Amazon product description or a condensed version)
- link — The URL where the product can be purchased. This is where it gets interesting for authors: you can link directly to your Amazon product page
- image_link — A URL to your book cover image, hosted on your website
- price — The current retail price (e.g., "14.99 USD" for paperback)
- availability — "in_stock" for published books
- brand — Your publishing imprint or author name
- gtin — The ISBN-13 of your book. This is the most important identifier for books in Merchant Center
- condition — "new" for all new books
- product_type — "Media > Books > Non-Fiction > [Your Category]"
Step 3: Submit via Google Sheets
The simplest way to submit a product feed for a small catalog is through Google Sheets. Merchant Center has a direct integration: create a Google Sheet with columns matching the feed fields above, enter your book data, and connect the sheet to Merchant Center as a feed source.
For six books, this takes about 20 minutes. No coding. No XML. Just a spreadsheet with your book information.
Step 4: Link to Amazon Without a Store
This is the question every author asks: "Can I link to Amazon instead of my own store?" Yes. Google Merchant Center allows product links to any legitimate product page, including Amazon. Set the link field to your book's Amazon URL (e.g., https://www.amazon.com/dp/B0GSCJPYZR/).
Google does not require you to be the merchant of record. You are listing a product that exists on a legitimate retailer and linking to where the customer can buy it. This is explicitly supported in Google's Merchant Center policies for books and media.
Step 5: Optimize Product Titles and Descriptions
Google's Shopping algorithm matches products to search queries based on product titles, descriptions, and category attributes. Optimize your book titles by including key search terms naturally:
- Instead of just "The W-2 Trap" use "The W-2 Trap: Why Your Salary Will Never Build Wealth — And the Tax Code Strategies to Fix It"
- Instead of just "The Resale Trap" use "The Resale Trap: New Build vs Resale Home — 25-Year Cost Analysis for All 50 States"
The description should include terms that potential buyers search for. Think about the queries that indicate purchase intent: "best personal finance book," "home building cost guide," "small business marketing book."
The Free Listings Advantage
Shopping Tab Visibility
When a user clicks the Shopping tab on a Google search, your free listing appears alongside paid ads and other organic listings. For book-related queries, the Shopping tab is increasingly where purchase-intent searches resolve — readers who have decided to buy are comparing options in the Shopping tab rather than scrolling through blog posts in the main search results.
Google Images Integration
Free product listings also appear in Google Images when users search for book-related terms. A search for "real estate investing books" in Google Images can surface your book cover with a "Product" badge and a link to purchase. This is a discovery channel that most authors do not even know exists.
Google Lens
When someone uses Google Lens to photograph a bookshelf, a physical book they see, or a screenshot of a book recommendation, Google can match the image to your Merchant Center listing and display purchase options. This is an emerging discovery channel that favors books with clear, distinctive cover images and properly submitted product data.
Results From Our Catalog
After listing all six books in Google Merchant Center, we tracked free listing impressions and clicks through the Merchant Center dashboard:
Month 1:
- Total free listing impressions across six books: 4,200
- Clicks to Amazon listings: 127
- Average position in Shopping tab for matched queries: 8.3
Month 3:
- Total free listing impressions: 11,800
- Clicks to Amazon listings: 342
- Average position improved to 5.1
The impressions grew as Google's algorithm gained confidence in our product data quality and our listings accumulated engagement signals. By month three, certain queries — particularly long-tail queries like "new construction cost book" and "W-2 income tax strategy book" — were surfacing our books in the top 5 Shopping results consistently.
The conversion from click to purchase cannot be tracked directly (once the user lands on Amazon, Google loses visibility), but based on Amazon's reported sales data during the same period, we estimated a click-to-purchase rate of approximately 15-20% — consistent with high-intent Shopping tab traffic.
Maintenance and Updates
Google Merchant Center requires minimal ongoing maintenance:
- Price updates — If you change your Amazon price, update the feed within 24 hours. Google suspends listings with price mismatches.
- Availability — Keep listings marked "in_stock" as long as the book is available on Amazon.
- Feed refresh — Google Sheets feeds auto-refresh daily, so any changes you make in the spreadsheet propagate automatically.
- New books — When you publish a new title, add a row to your spreadsheet. The new listing typically appears within 3-5 business days.
The total ongoing time commitment is less than 10 minutes per month — checking for any Merchant Center notifications and updating prices if needed.
Why Almost No Authors Do This
The main reason is awareness. Google Merchant Center is associated with e-commerce stores, not self-published books. Most authors do not realize that books qualify as products in Merchant Center, that Amazon links are acceptable as product URLs, or that the free listings program exists at all.
The second reason is the ISBN requirement. Google strongly prefers products with GTINs (for books, this means ISBN-13). If your book only has an ASIN and no ISBN, you can still list it, but you will need to apply for a GTIN exemption or obtain an ISBN. KDP assigns free ISBNs to paperback editions, so if you have a paperback version of your book, you already have an ISBN you can use.
Forty-five minutes of setup. Zero ongoing cost. Your books appearing alongside paid Shopping ads on the world's largest search engine. This is one of the most underutilized free marketing channels for authors in 2026.
