Help readers discover your backlist titles with always-on advertising

Your book launch may be over, but reader discovery continues. If your book has been published for longer than one year—what the industry calls a backlist title—the challenge is staying visible to capture ongoing demand. Every day, readers browse and discover books like yours.

According to a path-to-purchase study conducted with Kantar, 59% of book buyers were open-minded about which title they purchased, and 36% said they were swayed toward a different title than the ones they were searching for.¹ This means even highly intentional shoppers may still be making decisions in the moment.

This guide shows you how always-on advertising can help turn your backlist into a consistent source of sales without relying on short-lived launch spikes or constant new releases.

Readers are not just searching for specific books. They browse by genre, themes, similar authors, and related titles. According to the Kantar study, 79% of book shoppers in the Amazon store discover a new title or author during their journey.³ This means discovery is not the exception—it is the norm. Always-on advertising helps ensure your book stays visible while readers browse, appearing in relevant results and alongside similar titles. Instead of waiting to be found, you may be consistently part of the consideration set.

Always-on success is driven by how consistently you show up, not how much you spend. Instead of high spend over a short period, shift to sustainable, steady investment over time. This approach may help capture demand as it happens daily, allows campaigns to improve over time, and builds predictable visibility. You do not need to win the launch. You need to stay visible after it ends.

Always-on advertising may improve with time, not constant resets. Review performance every two weeks, not daily. Identify what may be driving engagement and gradually adjust budgets or targeting. Avoid turning campaigns on and off, making frequent reactive changes, or restarting campaigns too quickly—the longer your campaigns run, the more they may learn and the better they may perform. We recommend waiting about two weeks after the launch of your campaign before making your first optimization, then checking performance every two weeks to continue optimizing your campaign.

You can determine this by tracking your overall sales growth for advertised books and monitoring your total advertising cost of sales (TACOS), which shows your ad spend as a percentage of total sales.

You can measure this by reviewing your Customer Reviews count in the Reports + Marketing tab within Author Central. More reviews build social proof and indicate new readers are finding your books.

You can track this in Author Central by monitoring your Sales Rank in relevant categories and reviewing your Bookscan Weekly Sales Report if you are advertising books in a series. Watch for increased sales across your other titles as readers discover your complete catalog.

Always-on advertising works because it aligns with how readers behave. They discover, evaluate, and decide in real time, not just during launch windows.

Sign in to your Amazon Ads console and select Sponsored Products. If registering, select the country where you want to advertise, choose the Amazon Author option, and complete the registration flow. Sponsored Products ads promote individual books directly in results and on book detail pages on Amazon, Kindle, and Goodreads, helping you reach readers as they browse. Before you create your campaign, keep these guidelines in mind:

• Books you advertise must be available in the country where you are advertising.
• Books must be listed in Author Central.
• Ads must meet the creative requirements in the Amazon Ads guidelines and acceptance policies.
• Titles must meet the ad policy for books.

Start with one book that has strong reviews, clear genre alignment, and proven reader interest. Backlist titles may give you a stronger foundation for performance. Search by book title or Amazon Standard Identification Number (ASIN) and make sure to include all available formats, such as Kindle e-book, paperback, and hardcover.

You can choose between automatic targeting, where Amazon matches your book to relevant results and products, or manual targeting, where you select keywords or similar titles. Many authors begin with automatic targeting, then expand as they learn what works. If you are new to Sponsored Products, automatic targeting can help you learn as you go.

To support an always-on strategy, choose a daily budget you can sustain over time. The daily budget is the average amount you are willing to spend on a campaign in one day. It is spread out over one month and applied across all the days in that month. For example, if you budget ten dollars a day for 30 days, your total spend for the month will never exceed 300 dollars. Start with conservative bids and adjust gradually. Consistency may be more important than intensity. There are three different bidding strategies you can choose from:

1. Dynamic bids down only will reduce your bids in real time for clicks that may be less likely to convert to a sale. This strategy can offer greater control over spend as you learn what works and can help control spending on underperforming campaigns.
2. Dynamic bids up and down will increase your bids for auctions that are more likely to result in a sale. Bids will be increased by up to 100% for placements at the top of the first page of results and by up to 50% for all other placements. This is a useful strategy if you want to learn how much you should be bidding for specific keywords or books, if you want top of the page placement, or if you have a high performing campaign and want to maximize reader discovery.
3. Fixed bids uses your exact bid for all opportunities and will not adjust it. This strategy may get you more impressions but fewer clicks, compared to dynamic bids.

Once your campaign is live, give it time to gather meaningful information. Avoid making frequent early changes. Always-on performance may improve with stability. Look for what may be driving clicks and sales, where to increase visibility, and opportunities to refine targeting. Small adjustments may lead to meaningful improvements. You will have access to reports with insights on search terms, placements, keywords, and more. To find your reports, go to the measurement and reporting tab on the left sidebar in your advertising console. Review the results and adjust accordingly.

Readers are discovering books every day, and many may be open to finding something new along the way. With Amazon Ads, you can help ensure your books are part of that journey. Start with one backlist title, set a sustainable budget, and stay consistent. That is how always-on growth begins.
