Only the items listed in the table are required for a single run of the process.

5. Outputs

Output Name	Contents	Formatting Rules
Rewritten Copy	The revised copy, fully aligned with the brand voice and meeting the SEO objectives. Delivered as plain text, preserving original headings and structure.	– Use the same heading hierarchy as the original.
– Do not insert any system‑generated IDs or placeholders.
– Keep the document in plain‑text format (no PDF or other files).

• Keep each bullet under 100 characters.

6. Detailed Plan & Execution Steps

Collect the inputs – Ensure the Original Copy, Target Keywords, and any optional SEO objectives are present. Retrieve the Brand Voice Guide (Appendix A) and SEO Reference Guide (Appendix C) for reference.
Read the Brand Voice Guide – Note the required voice (e.g., friendly, expert), tone (e.g., conversational, professional), style rules (e.g., use active voice, avoid jargon), and any prohibited words.
List the target keywords – Confirm that each keyword or phrase is spelled correctly and is appropriate for the content.
Identify the core messages – Highlight the main points, benefits, and calls‑to‑action in the Original Copy.
Draft the rewrite –
- Keep the original structure (headings, sub‑headings).
- Rewrite each sentence using the voice, tone, and style from the Brand Guide.
- Insert each target keyword at least once, in a way that feels natural and maintains flow.
- Ensure sentences are concise and use active verbs, as required by the Brand Guide.
Apply SEO rules –
- Verify that the keyword density falls within the specified range (if provided).
- Check readability (e.g., using the Flesch‑Kincaid score) and adjust sentence length or word choice to meet the target readability level.
- Ensure total word count falls within the optional range, adjusting as needed without sacrificing meaning.
Self‑review –
- Scan the draft to confirm every target keyword appears.
- Compare the tone and style against the Brand Guide (e.g., friendliness, authority).
- Use a simple readability check (e.g., online readability calculator) to confirm the target score.
Finalize –
- Produce the Rewritten Copy in plain‑text format, preserving the original headings.
- Write a Change Summary (optional) that lists the key adjustments.
Record the outcome – Save the Rewritten Copy and the Change Summary for the record. If any validation step fails (see Section 7), flag the piece for manual review and do not produce a final output.

7. Validation & Quality Checks

Check	What to Verify	Action if Fail
All target keywords present	Each keyword from the list appears at least once in the Rewritten Copy.	If any are missing, insert them in the most logical location. If no appropriate spot exists, note the omission in the Change Summary and flag for manual review.
Keyword density	Compute the percentage of total words that are keywords.	If outside the allowed range, adjust by adding or removing instances while preserving readability.
Readability score	Use a readability calculator (e.g., Flesch–Kincaid).	If score is higher (harder) than target, rewrite long sentences or replace complex words.
Brand voice alignment	The tone matches the characteristics described in the Brand Voice Guide (e.g., friendly, authoritative).	If tone does not match, rewrite sentences to better reflect the voice.
Word‑count limits (if provided)	Total word count within the specified range.	If too short, expand with additional supportive details (still keeping brand tone). If too long, condense while retaining key messages.
Formatting	Headings preserved, no extra markup, plain text only.	Remove any unintended formatting and re‑export as plain text.
Completeness	All input sections were addressed and a Change Summary (if required) is attached.	If any item is missing, return to step 1 and request missing information.

If any check cannot be satisfied after reasonable effort, mark the output as “Requires Manual Review” and include a brief note on the issue.

8. Special Rules / Edge Cases

Situation	Handling
Missing Target Keywords	Proceed with rewrite using the available keywords. If any required keyword is absent from the list, note “Missing keyword: [keyword]” in the Change Summary and flag for review.
Conflicting Brand vs. SEO	Prioritize brand voice. Insert keywords only where they fit naturally; do not force awkward phrasing. Document any conflicts in the Change Summary.
Original Copy Empty	Do not proceed. Mark the request as “Cannot process – source copy missing” and forward for manual handling.
Multiple Brand Guides	Use the most recent version (as indicated by the date on the PDF). If there are contradictory instructions, follow the tone hierarchy in Appendix A (e.g., “primary tone > secondary tone”).
Readability Too Low	If readability is below target (i.e., too complex), rewrite sentences for simplicity, short sentences, and common vocabulary.
Keyword Over‑use	If a keyword appears more often than the maximum allowed density, remove or replace redundant instances, keeping at least one instance.
Length Exceeds Limits	Trim non‑essential adjectives, tighten sentences, and remove redundant sentences while preserving core messages.
Missing SEO Objectives	If no specific SEO objectives are given, default to:
• Keyword density 1‑2 %
• Readability grade ≤ 8
• Word count within 20 % of original length.

The Challenge of Keeping Brand Voice Consistent

Every piece of content—whether it’s a blog post, email, or social update—carries the weight of your brand’s personality. Inconsistent wording can erode trust, confuse customers, and dilute the image you’ve worked hard to build. Yet the manual process of cross‑checking each sentence against a voice guide is time‑consuming and prone to human error. Teams often end up with drafts that feel “close enough” but lack the cohesive tone that makes a brand memorable.

SEO Is a Balancing Act

Search engine optimization isn’t just about sprinkling keywords. It involves meeting readability standards, maintaining appropriate keyword density, and adhering to length guidelines—all without making the copy sound forced. Juggling these technical requirements while preserving a natural, engaging voice can feel like walking a tightrope. Miss a step, and the content either underperforms in search or feels out of character.

Consistency is the silent driver of brand trust.

When every headline, email, and social post sounds like it came from the same voice, customers feel confident and are more likely to engage.
