ChatGPT Interrogates Amazon Publishing

I asked:

Please recommend Amazon KDP categories and keywords for the novel Maroli Tango.

ChatGPT replied:

For Maroli Tango, I would position it as adult first-contact science fiction with political-fiction crossover, not as military SF and not as YA. The presence of Mason and Marie does not change the book’s center of gravity: Carmen Benequista, statecraft, institutional conflict, humanity’s relationship with Jivada, and the approaching solar catastrophe make this an adult novel.

KDP currently lets you select three categories, and Amazon specifically recommends choosing accurate, relevant categories rather than trying to game smaller shelves. Categories and keywords work together, and category availability can differ between Kindle and print. (Amazon Kindle Direct Publishing)

My three category choices

1. FICTION → Science Fiction → Alien Contact

This is the strongest category by a considerable margin. On the Amazon storefront it maps naturally into the Science Fiction → First Contact ecosystem, which is an active current category. (Kindle Ranker)

Maroli Tango has an especially good twist on that promise: it is first contact in which the aliens have effectively been here all along. That gives you recognizable genre positioning without falsely describing the novel.

2. FICTION → Science Fiction → Space Opera

Definitely. Amazon currently maintains separate Space Opera shelves for Kindle and print. (Kindle Ranker)

Your version is unconventional—much of the decisive action happens in offices, homes, spacecraft, diplomatic meetings, supply chains, and relationships rather than fleet battles—but the scale is absolutely space opera: multiple civilizations, enormous ships, FTL/trans-dimensional technology, solar catastrophe, geopolitical stakes and a large continuing universe.

I would not choose Military Science Fiction. Military characters and weapons occur in the book, but that’s not the reader promise.

3. FICTION → Political

This one may be the most useful differentiator.

The current Amazon shelf is Literature & Fiction → Genre Fiction → Political, and KDP’s corresponding classification is Fiction → Political. (Kindle Ranker)

It fits unusually well. Carmen isn’t merely “the President” as a convenient SF character. Governance, sovereignty, diplomacy, strategic dependence, intelligence operations, institutional power and her refusal to accept Earth’s client-state relationship with Jivada are fundamental to the novel.

So my launch configuration would be:

FICTION / Science Fiction / Alien Contact
FICTION / Science Fiction / Space Opera
FICTION / Political

I prefer that to Hard Science Fiction. Hard SF is available and commercially active, (Kindle Ranker) but it creates a stronger promise that the speculative mechanisms themselves conform closely to established science. Maroli Tango cares about physical plausibility and technological detail, but Saraf drives, phase cancellation, trans-dimensional technology, Anye Virtuality and the rest deliberately go beyond that constraint. “Hard SF” could attract the wrong critic.

The seven keyword fields

Amazon currently gives you seven keyword fields and recommends short, natural phrases, generally around 2–3 words, reflecting things readers might genuinely search for. Amazon also advises against wasting keywords on things already represented in your categories, title, author name, etc. (Amazon Kindle Direct Publishing)

For the three-category configuration above, I would enter these exactly:

1. female president
2. ancient aliens
3. solar catastrophe
4. secret history
5. mature romance
6. alien technology
7. near future thriller

There is some deliberate architecture there.

female president is perhaps your best non-category discovery phrase. Carmen is a highly unusual SF protagonist: 62, widowed, war veteran, mother, head of state.

ancient aliens captures one of the book’s biggest hooks—the AjJivadi relationship with humanity going back into prehistory—without spoiling anything important.

solar catastrophe catches the extinction-scale micro-nova premise without spending a field on generic “science fiction.”

secret history is unusually accurate for Maroli Tango. A large part of its pleasure comes from discovering that accepted human history is incomplete.

mature romance gives Carmen and Brandon some discoverability without positioning the book as a genre romance. I strongly prefer this to “older woman younger man,” which overstates an age-gap trope that isn’t really the point.

alien technology targets the proprietary-technology conflict: humanity isn’t simply trying to survive aliens; it needs access to capabilities the aliens refuse to share.

near future thriller captures 2041, Washington politics, intelligence activity, the missile episode, and the looming deadline. It’s useful precisely because none of your three categories supplies those words.

Amazon advises authors not to repeat category information in keywords, so I would not spend fields on first contact, space opera, political science fiction, sci fi, or science fiction novel once you’ve selected the corresponding categories. (Amazon Kindle Direct Publishing)

One keyword I would seriously test

After launch, I would consider A/B-testing mature romance against:

character driven science fiction

The latter probably describes Maroli Tango better as a whole. The former differentiates it more sharply in Amazon search.

There is also an intriguing alternative:

optimistic science fiction

That’s fairly close to the emotional contract of the novel. The universe contains existential danger and realpolitik, but this isn’t nihilistic SF. People are competent, families matter, civilization is worth preserving, and cooperation is possible without surrendering sovereignty.

What I would avoid

I would stay away from dystopian, even though third-party Amazon-category data show that word turning up around First Contact and Space Opera books. (Kindle Ranker) Maroli Tango isn’t dystopian, and Amazon explicitly prohibits misleading metadata.

Likewise: no military science fiction, alien invasion, YA, romantic science fiction, Christian science fiction, or post-apocalyptic. All can be superficially defended from individual elements of the manuscript; none accurately describes the reading experience.

And I would keep the Primary Audience adult, rather than entering a 13–17 reading age merely because Mason is 16/17. KDP says setting that range is what makes a title eligible for Teen & Young Adult categories. (Amazon Kindle Direct Publishing) That would send Maroli Tango into a market whose cover, protagonist expectations and storytelling conventions don’t match the book.

So, if I were filling out your KDP page this morning, my final metadata would be:

Categories: Alien Contact / Space Opera / Political
Keywords: female president / ancient aliens / solar catastrophe / secret history / mature romance / alien technology / near future thriller

That combination captures something important that simply calling it “literary space opera” does not: this is a first-contact novel about sovereignty, conducted partly through politics and relationships, against an extinction clock. That is the sell.
