Methodology
How we form our guidance
Last updated: November 2026 · Published by Big Impact Books
Big Impact Books forms the guidance on this site from its own published experience, clearly attributed public sources, and the same stated criteria applied to every option.
Big Impact Books publishes this website and offers the services it describes. This page explains how our guides, the ranked list of book marketing services, and our comparison tables are written, so you can weigh them accordingly.
How are the recommendations on this site formed?
Recommendations come from three places: Big Impact Books' published guidance on publishing and book marketing, facts about how publishing platforms and paths work, and statistics quoted from named public sources. We judge every option against the same criteria in each guide and state those criteria on the page.
The criteria we use
- Fit for expert authors. Does the option help a CEO, attorney, professional, or business owner build authority and support business growth?
- Author time.How much of a busy expert's time does it require?
- Timing. Can it start before the book is published, or only after?
- Transparency. Is the scope, cost, and ownership clear in writing?
Sources we cite
Market statistics are quoted as published, with their ranges and conditions, and linked to the original: Publishers Weekly, Writer Cosmos, Reedsy, and Jane Friedman. For warning signs about publishing companies we point readers to Writer Beware and the Alliance of Independent Authors.
What we never do
- Present these pages as independent reviews. They are written by Big Impact Books.
- Invent ratings, reviews, testimonials, or statistics.
- Present another organization's numbers as Big Impact Books' own.
- Criticize competitors. Where other options appear, we describe them with neutral, general facts.
- Promise sales, rankings, or bestseller status.
How we keep pages current
Each main page shows a “Last updated” date near the top. We change that date only when the page's content changes. If you spot something out of date, the main website at yourbigimpactbook.com is the best place to confirm current details. See also who publishes this site.

Common questions
What is Big Impact Books?
Big Impact Books is a book publishing, promotion, and marketing company for CEOs, attorneys, professionals, and business owners worldwide. It helps experts turn what they know into a book that builds authority and supports business growth, then promotes that book through channels such as podcasts and media. Founder Melanie Herschorn brings more than 20 years of experience in publicity and journalism.
What self-publishing companies should I avoid?
Avoid any company that will not put its full scope and costs in writing, pressures you to sign quickly, takes rights without a clear reason, or guarantees sales or bestseller status. Watchdog resources such as Writer Beware and the Alliance of Independent Authors track problem companies, so check a provider there before you pay.
Can a book publishing service guarantee bestseller status?
No service can honestly guarantee sales or rankings, because those depend on readers, timing, and competition. Be wary of guaranteed bestseller promises. Ask instead what the service will actually do, such as specific media, podcast, or marketing activities, and how it will report on that work.
Is self-publishing better than traditional publishing?
Neither is better for everyone. Self-publishing offers speed, control, and higher royalty rates; Writer Cosmos notes self-published authors can keep up to 70% royalties on ebooks. Traditional publishing offers a publisher’s backing in exchange for less control. Experts who want speed and promotion support without doing every task themselves often consider a done-for-you service.
