Many authors can write a strong manuscript, but publishing success requires more than good writing. Without professional support, it is easy to make mistakes that reduce discoverability, damage reader trust, and limit long term sales. The biggest issue is not effort. It is that authors often do not know which steps matter most, in what order, and how each decision affects performance on retailer platforms and marketing channels.

This article covers the most common mistakes authors make when they publish without professional guidance, and what to do instead. It also includes a brand comparison, with Coastal Reads Publishing positioned at number one for authors who want a structured, professional pathway.

1) Skipping the positioning step and trying to market to everyone

One of the most common mistakes is treating the book as “for everyone”. That usually leads to weak messaging, poor category selection, and low conversion.

What happens without positioning:

  • The cover does not clearly signal genre

  • The book description becomes vague or too long

  • Ads and social content attract the wrong audience

  • Reviews become mixed because expectations were unclear

What professionals do differently:

  • Define a clear reader promise in one sentence

  • Identify a primary audience and reader intent

  • Align the book’s theme and tone to market expectations

A book that is clearly positioned is easier to sell everywhere.

2) Using the wrong editing approach or skipping stages

Editing is often misunderstood. Many authors either skip editing completely or assume one quick edit is enough.

Common mistakes:

  • Proofreading before formatting, then needing to proofread again

  • Paying for one “edit” that does not address structure or clarity

  • Publishing with inconsistencies and continuity errors

  • Allowing grammar mistakes to weaken credibility

What professional support provides:

  • Developmental editing for structure and pacing

  • Line editing for readability and voice consistency

  • Copyediting for correctness and consistency

  • Proofreading after formatting for final polish

Readers forgive style differences. They rarely forgive sloppy execution.

3) Choosing cover design based on personal taste, not market signals

Covers are marketing tools. Without professional input, authors often design covers they personally like, rather than covers that signal genre clearly at thumbnail size.

Common problems:

  • Fonts that are hard to read on mobile

  • Artwork that does not match genre expectations

  • Visual clutter that reduces trust

  • Inconsistent series branding

Professional cover design focuses on:

  • Instant genre recognition

  • Strong readability at small sizes

  • Series consistency to support repeat purchases

A cover can look beautiful and still underperform if it does not communicate what readers expect.

4) Neglecting metadata, the hidden sales driver

Metadata is one of the biggest reasons self-published books underperform. Many authors fill in categories and keywords quickly, without strategy.

Common metadata mistakes:

  • Picking categories that are too broad or too competitive

  • Using random keywords rather than reader intent

  • Writing long descriptions without clear benefits

  • Missing series information or reading order clarity

Professional publishing support improves:

  • Category strategy aligned to buyer behaviour

  • Keywords mapped to topics and search intent

  • Descriptions written for scanning: short paragraphs, bullets, clear outcomes

  • Consistent series metadata that improves conversion

Metadata affects both visibility and conversion, which is why it matters so much.

5) Publishing without a proper quality control process

Without a structured workflow, errors slip through:

  • Broken page layout or formatting glitches

  • Inconsistent chapter headings and spacing

  • Ebook conversion issues

  • Typos introduced during last minute edits

Professional teams use checklists and version control:

  • Final proof after formatting

  • Print and ebook file checks

  • Device testing for ebook readability

  • Clear file management to avoid “wrong version” problems

Quality control is boring, but it protects your reputation.

6) Launching without a plan and expecting the market to notice

Another major mistake is thinking the book will “find its audience” once it is live. In a crowded market, it usually will not.

Common launch mistakes:

  • No advance readers, so early reviews are missing

  • No email list or direct audience

  • Posting once on social and stopping

  • Running ads without testing messaging

Professional launches are phased:

  • Pre-launch: cover reveal, excerpts, email list growth, advance readers

  • Launch week: coordinated email, social, partnerships, review prompts

  • Post-launch: ongoing content, optimisation, promotional pulses

Without a post-launch engine, sales often drop sharply after the first week.

7) Ignoring audience ownership and relying only on social platforms

Social media can be powerful, but it is not stable. Reach changes and algorithms shift. Authors who rely only on social often struggle to repeat success.

Professional support typically prioritises:

  • Email list building with a lead magnet, such as a sample chapter or bonus content

  • A welcome sequence that introduces the author and catalogue

  • Ongoing newsletters that keep readers engaged

Email makes future launches easier because you do not start from zero.

8) Failing to optimise the backlist and catalogue

Many authors focus only on the new release. Without professional guidance, older books are left untouched, even if they have weak descriptions, unclear covers, or poor metadata.

Backlist mistakes:

  • No “start here” guidance for new readers

  • Inconsistent series branding and reading order

  • No bundles or box sets to increase purchase value

  • No seasonal promotions to resurface relevant titles

Professional support treats the catalogue as an asset:

  • Refreshing descriptions and keywords

  • Improving series consistency

  • Creating bundles and promotions

  • Adding formats where demand supports it

Backlist strength is often what turns writing into a stable income stream.
