## Prioritized recommendations retained in the report

### 1. Put a direct answer on the page your buyer will find (Technical GEO)
The question “香港潮濕天氣經常要在室內晾衫，有哪些洗衣劑品牌值得比較？ in Hong Kong?” is a content brief: the reader needs a clear answer about Walch, not another broad brand slogan.

Deliverable: Improve the existing page on walchhk.com that best answers this question. Use the buyer's wording as a heading, then explain the job Walch can actually do, who it fits and its important limit. Follow with a real example and a link to the relevant product or service detail. Keep that answer visible without a login; ask your web team to fix access only if the answer is genuinely hidden.

Success check: A new visitor can find the answer, understand the fit and inspect the example on the page. Keep any useful existing explanation rather than replacing it.

Relevant buyer questions:
- 香港潮濕天氣經常要在室內晾衫，有哪些洗衣劑品牌值得比較？ in Hong Kong?

Retained evidence: E2, E3, E4

Ready Scan guidance:
- Write around a real buying question: https://knowledge.readyscan.ai/buyer-questions
- Turn findings into useful page improvements: https://knowledge.readyscan.ai/marketing-actions

### 2. Give buyers one reliable product fact sheet (Technical GEO)
Before an AI answer can explain why Walch fits, its product name, offering and buying conditions need a clear, consistent home.

Deliverable: Use https://walchhk.com/ or its existing product page for a concise fact sheet: intended customers, supported jobs, inputs and outputs or service scope, pricing basis, availability and material limits. Link to the current pricing and policy details. Correct conflicting descriptions on pages you control, including metadata your web team maintains.

Success check: A buyer can answer the conditions in the selected question from those pages, and the same fact does not contradict itself elsewhere on the site.

### 3. Connect your homepage to the answers and proof (Technical GEO)
Useful content cannot support the buying decision when a visitor cannot find the page that answers “家人不喜歡濃烈香味，在香港有哪些低香味或無香料洗衣劑品牌值得了解？ in Hong Kong?”.

Deliverable: Add a descriptive link from https://walchhk.com/ to the strongest existing answer page, then link that page to its worked example, comparison and relevant buying action. Use labels that name the task, not “click here”. Have the web team confirm that the pages and ordinary links are publicly accessible; do not create duplicate pages for small wording changes.

Success check: Starting on the homepage, a buyer can follow the links to the answer, its supporting proof and an appropriate next step.

This report's answers cite consumer.org.hk, kao.com, ariel-hk.com. Those pages show the kinds of information buyers and answer systems are using.

Deliverable: Use the cited pages to understand what information helps the buyer. Choose an independent publication or community your buyers use; a competitor's documentation is a content reference, not an outreach target. Prepare a short Walch pitch around a useful worked example, an original finding or a specific audience need. Link to the supporting product page and follow the publisher's submission process. For an existing factual error, send its owner the exact correction and source.

Success check: Track published coverage and accepted factual corrections with their URLs. Do not count a sent pitch as coverage or manufacture reviews, endorsements or inclusion.

Keep the questions and settings comparable so the next report can show useful changes in mentions, citations and recommendations.

Deliverable: After publishing the chosen improvements, record the page URLs and dates. Request a new Walch check with the same buyer questions, region, language and AI systems. Keep this report as the baseline and compare the complete answers as well as the scores.

Success check: Record which questions gained a mention, citation or recommendation, which did not, and any change in answer coverage. A published edit alone is not a measured visibility gain.

## Report interpretation
Walch was recommended in 3 of 12 scored AI answers.

Walch appeared in retained answers for 3 of 4 buyer questions and was recommended for 3 of them. Ariel is the most consistent competitor signal to address because it recurred when Walch was not surfaced or was explicitly not recommended.

### Market read

Walch was recommended in 3 of 12 scored AI answers, mentioned in 3, and cited in 0.
Evidence: E4, E1, E12, E2, E3, E5, E6, E7

### Competitor context

Ariel appeared across 3 buyer questions (4 scanned AI answers) when Walch was not surfaced. A named alternative alone does not establish that it was recommended.
Evidence: E2, E3, E6, E9

Ariel was named in 6 retained AI answers across 4 buyer questions. This is comparable-product context, not a recommendation count.
Evidence: E2, E3, E4, E6, E9, E12

### Growth opportunities

Walch did not surface on 1 selected buyer question with conclusive assessments. These answers do not establish why it was absent.
Evidence: E7, E8, E9

Ariel recurred where Walch was absent or explicitly disfavored. Review the stated buyer requirements before deciding whether a comparison or a website change is warranted.
Evidence: E2, E3, E6, E9

Walch was mentioned or recommended in 3 retained answers without a target-owned citation. This is an observed citation gap, not evidence of a crawlability, page-structure or schema problem.
Evidence: E4, E1, E12
