What is book metadata?
In the simplest terms, book metadata is data about data. It’s the information about your book that essentially represents its fingerprint online, including basic details like the title, author name, and ISBN, all the way to more nuanced information like subtitles, descriptions, and BISAC codes.
By optimizing this data, you’re taking the time to improve each field by adding in the exact phrases your potential readers would use when searching. We call this metadata optimization. When you’re marketing to a niche audience, you don’t get the broad swaths of searchers looking for generic things like “romance novels” or “mystery thrillers.” You instead want to target those readers who are looking specifically for the type of book you’re selling, which is where long-tail keywords come into play.
What are long-tail keywords?
Long-tail keywords are more in-depth, detailed search queries like “Victorian steampunk romance” rather than just “romance.” These terms are used by Amazon, Google, and other search engines and capture your readers’ intent much more precisely than more generic terms. Long-tail keywords often match the setting, themes or other specifics that your niche genre book deals with.
But why are they called long-tail? Simply because when you look at a search chart showing the terms that people search for, there’s a short “head” of generic terms, but a “long tail” of more specific terms. There are fewer searches, but those that are searching are highly interested in what you have to offer.
Why do long-tail keywords matter for niche genre authors?
Whether you’re writing a culinary mystery or a dark fantasy series set in Australia, you face incredible competition if you’re aiming for keywords like “mystery” or “dark fantasy.” Instead, long-tail keywords help you reduce competition while still increasing the chances that your book will rank higher in the search results simply because it is so specific.
What’s more, readers who type in detailed queries (think “post apocalyptic romance with cats”) are showing clear intent and are much more likely to make a purchase. When your metadata precisely matches what they’re looking for, your conversion rate (that is, the percentage of people who buy or order from you) rises.

How to make long-tail keywords a part of your book metadata
Now that you know more about what metadata is and how long tail keywords work, how do you blend them together? How can you use them effectively as part of your book marketing strategy?
The secret is to integrate them in a natural way across all the metadata fields you’re given. This varies from platform to platform, so there’s no “one size fits all” process for every retailer and every website. Most importantly, though, you want to use them naturally:
- In the title and subtitle – If you have enough space, weave one or two high-value phrases in without sacrificing readability.
- Book description – Use your most important long-tail keywords here. You’ll want anywhere from 2-3 keyword instances per 100 words. What you want to avoid is “keyword stuffing” — adding in too many keywords at the expense of everything else. Search engines (and your readers) are not a fan of that.
- Keyword slots – Retailers like Amazon KDP offer up to seven keyword fields. Use these to add in a specific long-tail phrase and make sure they don’t overlap.
- BISAC codes and categories – These are controlled in terms of what their names are, but you can choose the nearest appropriate category, such as Fiction / Romance / Paranormal & Urban, rather than just Fiction / Romance
How do I find long-tail keywords?
There are several ways to find long-tail keywords that your potential readers may use, including:
- Amazon autocomplete & search suggestions: Begin typing terms relevant to your genre in Amazon’s search bar. The resulting autocomplete suggestions are actual search queries used by readers, and those make excellent long-tail keywords.
- Genre forums & reader communities: Explore niche subreddits, Goodreads groups, or Facebook communities. Note the language and phrases readers use to describe books like yours.
- Keyword planning tools: While platforms like Amazon don’t offer built-in research tools, external SEO tools can provide search volume and competition metrics for your candidate phrases. Our author SEO guide encourages you to combine tools in order to get the best possible results (and stand out from the competition).
- Competitor analysis: Review top-selling books in your subgenre. Take a closer look at their titles, subtitles, and descriptions to uncover recurring long-tail phrases you might adapt for your own metadata.
Getting listed and getting found with metadata and long-tail keywords
Just because you specialize in a niche genre doesn’t mean your work needs to be hidden from the mainstream! Long-tail keywords are a great way to stand out from the crowd and connect directly to the readers who will appreciate your work the most. By combining tools and research, you’ll be able to get noticed and get sales.
