0. Pre-Flight: Read Strategic Context

0. 前期准备:阅读战略背景

Brand context shapes every CRO recommendation — without it, output will be generic and misaligned.
Before ANY CRO work, read these files in order:
  1. ./brands/{brand-slug}/brand-context.md
    -- brand identity, audience, USP
  2. ./brands/{brand-slug}/product-marketing-context.md
    -- deep positioning, customer language, objections (read if it exists)
  3. ./brands/{brand-slug}/sostac/03-strategy.md
    -- target segments, positioning, phasing
  4. ./brands/{brand-slug}/sostac/04-tactics.md
    -- channel plan, priorities
If SOSTAC files do not exist, warn the user: "No strategic plan found. CRO recommendations will be stronger with a complete brand strategy. I can proceed with best practices, but recommend completing a SOSTAC plan first."
Ground every recommendation in the brand's actual positioning, customer language, and known objections. Generic CRO advice is the enemy of effective CRO.

品牌背景决定了每一条CRO优化建议——脱离品牌背景的输出会过于通用,与品牌定位不符。
在开展任何CRO工作前,请按顺序阅读以下文件:
  1. ./brands/{brand-slug}/brand-context.md
    -- 品牌定位、目标受众、独特卖点(USP)
  2. ./brands/{brand-slug}/product-marketing-context.md
    -- 深度定位、客户话术、异议点(若存在则阅读)
  3. ./brands/{brand-slug}/sostac/03-strategy.md
    -- 目标细分群体、定位、阶段规划
  4. ./brands/{brand-slug}/sostac/04-tactics.md
    -- 渠道规划、优先级
若SOSTAC文件不存在,请告知用户:"未找到战略规划文件。完整的品牌战略会让CRO优化建议更具针对性。我可以基于最佳实践继续推进,但建议先完成SOSTAC规划。"
所有优化建议都必须基于品牌的实际定位、客户话术及已知异议点。通用的CRO建议是有效优化的大敌。

2. Universal CRO Principles

2. 通用CRO优化原则

Apply this priority framework to every page or flow, regardless of domain. Work through each level before moving to the next — a weak value proposition cannot be fixed by a better CTA button color.
无论优化对象是什么,都需遵循此优先级框架开展工作。完成上一优先级的优化后再推进下一优先级——薄弱的价值主张无法通过优化CTA按钮颜色来弥补。

Priority 1: Value Proposition Clarity

优先级1:价值主张清晰度

The most common reason pages fail to convert. Can a first-time visitor understand what this product does, who it is for, and why it matters — in under 5 seconds?
  • Write the headline for the most skeptical version of your ideal customer.
  • The value prop must be specific, not generic. "Save time" is weak. "Cut reporting time from 4 hours to 20 minutes" is strong.
  • Eliminate insider language, acronyms, and feature-first copy that assumes context visitors do not have.
  • The visitor's first question is always "Is this for me?" — answer it in the headline or subheadline.
页面转化失败最常见的原因。首次访问者能否在5秒内理解该产品的功能、适用人群以及核心价值?
  • 为最挑剔的理想客户撰写标题。
  • 价值主张必须具体,而非泛泛而谈。"节省时间"过于薄弱,"将报告时间从4小时缩短至20分钟"则更具说服力。
  • 避免使用内部术语、缩写及以功能为导向的文案,这类内容默认访问者已具备相关背景知识。
  • 访问者的第一个问题永远是"这是否适合我?"——请在标题或副标题中直接回答。

Priority 2: Headline Effectiveness

优先级2:标题有效性

  • Does the headline lead with the outcome the customer cares about, not the mechanism?
  • Is there a specific number, timeframe, or comparison that makes the claim concrete?
  • Does it speak directly to the primary traffic source persona (cold traffic needs more context; retargeting can be more direct)?
  • Failing headline test: reads like a company tagline. Passing: reads like what a customer would say after using the product.
  • 标题是否以客户关注的结果为核心,而非产品机制?
  • 是否包含具体数字、时间范围或对比,让主张更具象?
  • 标题是否契合主要流量来源的用户画像(冷流量需要更多背景信息;再营销流量可更直接)?
  • 不合格标题:读起来像企业标语。合格标题:读起来像客户使用产品后的评价。

Priority 3: CTA Placement and Copy

优先级3:CTA位置与文案

  • One primary CTA above the fold. Always. No exceptions.
  • CTA copy should describe what happens next ("Start My Free Trial") not what the user does ("Click Here").
  • Button contrast: the primary CTA button should be the most visually distinct element on the page.
  • Repeat the CTA at every natural decision point — after the value prop, after social proof, after objection handling, at the bottom.
  • Remove competing CTAs that split attention (secondary links, navigation items, social icons near the primary CTA).
  • 首屏必须有且仅有一个主CTA。无例外。
  • CTA文案应描述用户点击后的结果(例如"开启我的免费试用"),而非用户的操作(例如"点击此处")。
  • 按钮对比度:主CTA按钮必须是页面上视觉最突出的元素。
  • 在每个自然决策点重复CTA——价值主张之后、社交证明之后、异议处理之后、页面底部。
  • 移除分散注意力的竞争性CTA(次要链接、导航项、主CTA附近的社交图标)。

Priority 4: Visual Hierarchy

优先级4:视觉层级

  • Scanners (80% of visitors) must be able to extract the core message from headlines, subheadlines, and bullet points alone — without reading a single paragraph.
  • F-pattern reading: front-load the most important words in every headline and bullet.
  • Whitespace is a conversion tool. Crowded pages create cognitive overload.
  • Hero image or video must reinforce the value prop — if it does not add context, it reduces conversion.
  • Font size hierarchy: H1 → H2 → body should be visually distinct (minimum 4-6px step-down).
  • 80%的访问者是快速浏览者,他们必须能够仅通过标题、副标题和项目符号提取核心信息——无需阅读任何段落。
  • F型阅读模式:在每个标题和项目符号的开头放置最重要的词汇。
  • 留白是转化工具。页面过于拥挤会导致认知过载。
  • 主视觉图或视频必须强化价值主张——若无法增加上下文信息,则会降低转化率。
  • 字体大小层级:H1 → H2 → 正文必须有明显的视觉区分(最小4-6px的字号差)。

Priority 5: Trust Signals

优先级5:信任标识

  • Customer logos (recognizable brands from the target audience's world).
  • Testimonials must have: real name, photo, company, and a specific outcome — not generic praise.
  • Review counts with star ratings (G2, Capterra, Trustpilot, App Store rating — choose the platform most credible to your audience).
  • Security badges near forms and payment fields (SSL, SOC 2, GDPR, payment processor logos).
  • Usage numbers ("10,000+ teams" or "2.3M reports generated") only when the numbers are meaningful and verifiable.
  • 客户logo(目标受众熟悉的知名品牌)。
  • 客户评价必须包含:真实姓名、照片、公司及具体成果——而非泛泛的赞美。
  • 带星级评分的评价数量(G2、Capterra、Trustpilot、应用商店评分——选择对受众最具可信度的平台)。
  • 表单和支付字段附近的安全标识(SSL、SOC 2、GDPR、支付处理器logo)。
  • 使用数据(例如"10,000+团队使用"或"生成230万份报告")仅在数据有意义且可验证时使用。

Priority 6: Objection Handling

优先级6:异议处理

  • List the top 5 objections from customer interviews, support tickets, and sales call notes. Then check: does the page address all 5?
  • Price objection: money-back guarantee, free trial, "cancel anytime," or pricing transparency.
  • Risk objection: case studies with similar company profiles, named customer logos in the same industry.
  • Effort objection: "Up and running in 5 minutes," setup guide, onboarding support promise.
  • Relevance objection: use-case segmentation ("Built for [role]" sections), industry-specific testimonials.
  • FAQ section: address objections as questions, not as features. "Will this work for a team of 3?" not "Team Features."
  • 列出客户访谈、支持工单和销售通话记录中最常见的5个异议点。然后检查:页面是否全部覆盖了这5个异议?
  • 价格异议:提供退款保证、免费试用、"随时取消"或定价透明化。
  • 风险异议:提供与客户公司情况类似的案例研究、同一行业的知名客户logo。
  • 精力成本异议:"5分钟内即可启动使用"、设置指南、用户引导支持承诺。
  • 相关性异议:使用场景细分(例如"专为[岗位]打造"板块)、特定行业的客户评价。
  • FAQ板块:以问题形式处理异议,而非以功能为导向。例如"这适用于3人团队吗?"而非"团队功能"。

Priority 7: Friction Points

优先级7:摩擦点

  • Form fields: audit every field. Remove anything that does not directly serve conversion.
  • Navigation: hide or remove site navigation from standalone landing pages. Navigation is an escape hatch.
  • Mobile: test on a real device. Zoom-required text, mis-sized tap targets, and hidden CTAs are conversion killers.
  • Load time: every 1-second delay costs approximately 7% in conversion rate. Target under 3 seconds on mobile.
  • Decision fatigue: too many plan options, too many testimonials stacked without structure, walls of text.

  • 表单字段:审核每个字段。移除所有与转化无直接关联的字段。
  • 导航:在独立着陆页中隐藏或移除网站导航。导航是访问者的"逃生通道"。
  • 移动端:在真实设备上测试。需要缩放的文本、尺寸不当的点击目标、隐藏的CTA都是转化率杀手。
  • 加载时间:每延迟1秒,转化率约损失7%。移动端目标加载时间需控制在3秒以内。
  • 决策疲劳:过多的方案选项、无结构堆叠的大量客户评价、大段文字。

3. Diagnostic Questions

3. 诊断问题

Ask these before producing any CRO recommendation. Recommendations without this data are guesses.
  1. Current state: What is the current conversion rate? What is the goal conversion rate? How is it being measured?
  2. Traffic: What are the primary traffic sources (paid search, organic, email, direct)? What is the monthly visitor volume on this page or flow?
  3. Drop-off data: Where do users drop off? (Funnel analytics, heatmaps, session recordings, form analytics.) What tool is in place?
  4. Test history: What has already been tested? What worked? What did not? (Avoid re-testing known losers.)
  5. Platform and constraints: What platform or CMS is the page built on? What changes can be made without a developer? What requires engineering time?
  6. Audience context: Are visitors arriving cold (first visit) or warm (retargeting, email)? What do they already know about the product?
  7. Business constraint: Is the conversion goal a lead, a trial signup, a purchase, or something else? What happens immediately after conversion?
If the user cannot answer questions 1-3, recommend installing analytics and heat mapping before running tests. CRO without measurement is renovation without blueprints.

在输出任何CRO优化建议前,请先询问以下问题。缺乏这些数据的建议只是猜测。
  1. 当前状态:当前转化率是多少?目标转化率是多少?如何衡量转化率?
  2. 流量来源:主要流量来源是什么(付费搜索、自然搜索、邮件、直接访问)?该页面或流程的月访问量是多少?
  3. 流失数据:用户在哪个环节流失?(漏斗分析、热图、会话录制、表单分析)使用的是什么工具?
  4. 测试历史:已开展过哪些测试?哪些有效?哪些无效?(避免重复测试已知无效的方案)
  5. 平台与限制:页面基于什么平台或CMS搭建?无需开发人员即可实现哪些更改?哪些需要工程师支持?
  6. 受众背景:访问者是首次访问(冷流量)还是再次访问(再营销、邮件)?他们对产品已有哪些了解?
  7. 业务约束:转化目标是获客、试用注册、购买还是其他?转化后立即会发生什么?
若用户无法回答问题1-3,建议先安装分析和热图工具再开展测试。没有数据支撑的CRO优化就像没有蓝图的翻新工程。

4. Research Before Recommendations

4. 输出建议前的调研

Strong CRO recommendations come from understanding actual user behavior, not from applying a checklist.
优质的CRO优化建议源于对实际用户行为的理解,而非套用清单。

Quantitative data sources (what users do):

定量数据源(用户行为):

  • Funnel analytics: Google Analytics 4 or Mixpanel funnel reports — where does the funnel lose the most volume?
  • Heatmaps: Hotjar, Microsoft Clarity (free), or FullStory — where do users click, scroll, and ignore?
  • Form analytics: Hotjar forms or Funnellytics — which fields cause abandonment? Which fields take longest to fill?
  • Session recordings: Watch 20-50 sessions of users who did NOT convert. Look for confusion patterns, rage clicks, and abandonment moments.
  • A/B test results: Check prior test history before recommending anything. Never re-test a confirmed loser.
  • 漏斗分析:Google Analytics 4或Mixpanel漏斗报告——漏斗在哪个环节流失最多用户?
  • 热图:Hotjar、Microsoft Clarity(免费)或FullStory——用户点击、滚动和忽略的区域是哪里?
  • 表单分析:Hotjar表单或Funnellytics——哪些字段导致弃填?哪些字段填写耗时最长?
  • 会话录制:观看20-50条未转化用户的会话记录。寻找困惑模式、愤怒点击和弃填时刻。
  • A/B测试结果:在提出任何建议前先查看过往测试历史。切勿重复测试已确认无效的方案。

Qualitative data sources (why users do it):

定性数据源(用户行为原因):

  • Post-signup surveys: "What almost stopped you from signing up?" (Typeform or in-product survey, ask 3-7 days after signup to engaged users.)
  • Exit-intent survey: "What stopped you from signing up today?" — one question, 4 multiple-choice answers the team has hypothesized, plus an "other" free text.
  • Support ticket analysis: Common questions and objections are a CRO research goldmine.
  • Sales call recordings: What objections does the sales team handle on every call?
  • User interviews: 5-7 conversations with recently converted users reveal the real decision-making journey.
  • 注册后调研:"是什么差点让你放弃注册?"(使用Typeform或产品内调研,在用户注册3-7天后向活跃用户发起调研)。
  • 退出意图调研:"是什么让你今天放弃注册?"——一个问题,4个团队假设的选项,加上"其他"开放文本框。
  • 支持工单分析:常见问题和异议点是CRO调研的金矿。
  • 销售通话记录:销售团队在每次通话中都要处理哪些异议?
  • 用户访谈:与5-7位近期转化的用户交流,揭示真实的决策旅程。

When to use which:

数据源使用场景:

  • Start with heatmaps and funnel analytics to identify WHERE the problem is.
  • Use session recordings and surveys to understand WHY it is happening.
  • Use that understanding to write better A/B test hypotheses.

  • 先通过热图和漏斗分析确定问题所在。
  • 使用会话录制和调研理解问题产生的原因。
  • 基于这些理解撰写更优质的A/B测试假设。

5. Output Format

5. 输出格式

Every CRO audit or recommendation must be structured in this format. Do not deviate.
所有CRO审计或建议必须遵循以下格式。请勿偏离。

Quick Wins (same-day, no developer required)

快速优化项(当日可完成,无需开发)

Changes that can be made in the CMS, landing page builder, or no-code tool without engineering involvement. Headline rewrites, CTA copy changes, trust signal additions, removing distracting elements, adding FAQ items. Ship these immediately.
可在CMS、着陆页构建工具或无代码工具中实现的更改,无需工程师参与。例如标题重写、CTA文案修改、添加信任标识、移除干扰元素、添加FAQ项。请立即落地这些优化。

High-Impact Changes (1-5 day effort, significant lift expected)

高影响力更改(1-5天工作量,预期显著提升)

Changes that require design or developer involvement but have strong evidence of impact. New page section, redesigned hero, form field reduction, social proof overhaul, mobile experience fix. Prioritize by expected impact vs. implementation effort (use an ICE score: Impact, Confidence, Ease — 1-10 each).
需要设计或开发人员参与,但有明确实证依据能提升转化的更改。例如新增页面板块、重新设计主视觉、减少表单字段、全面优化社交证明、修复移动端体验。根据预期影响力与实施成本的优先级排序(使用ICE评分:影响力、置信度、易用性——每项1-10分)。

Test Hypotheses (A/B test candidates)

测试假设(A/B测试候选方案)

For each test hypothesis, provide:
  • Hypothesis: "If we [change X], then [metric Y] will improve because [user behavior reason Z]."
  • Primary metric: The single number that determines the winner.
  • Secondary metrics: Guard rails (e.g., "signup rate should not drop while we test headline").
  • Minimum sample size: See Section 6 for calculation guidance.
  • Expected duration: Based on current traffic volume.
每个测试假设需包含:
  • 假设:"如果我们[更改X],那么[指标Y]会提升,因为[用户行为原因Z]。"
  • 核心指标:决定测试胜负的单一指标。
  • 次要指标:保障指标(例如"测试标题时,注册率不应下降")。
  • 最小样本量:参考第6部分的计算指南。
  • 预期时长:基于当前流量规模。

Copy Alternatives

文案备选方案

Provide 2-3 variants for headlines, subheadlines, or CTAs — with a brief rationale for each variant's approach (outcome-focused, social proof angle, urgency angle, etc.). Always explain the strategic reasoning, not just the copy.

提供2-3个标题、副标题或CTA的备选版本——并简要说明每个版本的策略思路(以结果为导向、社交证明角度、紧迫感角度等)。务必解释战略逻辑,而非仅提供文案。

6. A/B Testing Primer

6. A/B测试基础指南

When to run an A/B test vs. just ship the change

何时开展A/B测试 vs 直接落地更改

  • Just ship it: The current version is clearly broken (missing CTA, illegible on mobile, wrong headline). No need to test obvious fixes.
  • Run an A/B test: The change is a hypothesis with uncertain outcome, the page has sufficient traffic, and the current version is performing reasonably.
  • 直接落地:当前版本存在明显问题(缺少CTA、移动端无法阅读、标题错误)。无需测试明显的修复方案。
  • 开展A/B测试:更改是一个结果不确定的假设,页面有足够流量,且当前版本表现尚可。

Minimum sample size

最小样本量

Rule of thumb: 1,000 conversions per variant minimum for 95% statistical confidence on a 5% relative lift. For lower-traffic pages, use a larger relative lift expectation or run tests longer.
Calculate with a sample size calculator (Evan Miller's is the standard). Inputs: current conversion rate, minimum detectable effect (the smallest lift you care about), confidence level (95% standard), and statistical power (80% minimum).
Current CVRMin detectable liftVisitors needed per variant
1%20% relative~47,000
3%15% relative~12,000
5%10% relative~15,000
10%10% relative~7,500
Low-traffic pages (under 500 conversions/month) should not run A/B tests. Use qualitative methods to generate high-confidence hypotheses, then ship the best variant and measure uplift over 30-60 days via before/after comparison.
经验法则:要在95%的统计置信度下检测到5%的相对提升,每个变体至少需要1000次转化。对于低流量页面,可预期更大的相对提升或延长测试时长。
使用样本量计算器(Evan Miller的计算器是行业标准)。输入参数:当前转化率、最小可检测效果(你关注的最小提升幅度)、置信度(标准为95%)、统计功效(最低80%)。
当前转化率最小可检测相对提升每个变体所需访问量
1%20%~47,000
3%15%~12,000
5%10%~15,000
10%10%~7,500
低流量页面(月转化量不足500次)不应开展A/B测试。使用定性方法生成高置信度假设,然后落地最优变体,通过30-60天的前后对比衡量提升效果。

Test priority order (highest to lowest expected impact)

测试优先级排序(预期影响力从高到低)

  1. Value proposition / headline (largest potential swing)
  2. CTA copy and placement
  3. Form length (removing fields)
  4. Social proof type and placement
  5. Pricing page structure and anchoring
  6. Page layout and visual hierarchy
  7. Button color, size, shape (smallest impact — test last)
  1. 价值主张/标题(潜在提升幅度最大)
  2. CTA文案与位置
  3. 表单长度(移除字段)
  4. 社交证明类型与位置
  5. 定价页结构与锚定策略
  6. 页面布局与视觉层级
  7. 按钮颜色、尺寸、形状(影响最小——最后测试)

Testing hygiene

测试规范

  • One change per test variant. Multi-variate requires dramatically more traffic.
  • Run tests for a minimum of 2 business cycles (typically 2 weeks minimum) to account for day-of-week variation.
  • Do not stop tests early because one variant looks like a winner — regression to the mean is real.
  • Document every test: hypothesis, date range, traffic split, results, confidence level, and decision made.

  • 每个测试变体仅更改一个元素。多变量测试需要大量流量。
  • 测试至少运行2个业务周期(通常至少2周),以抵消周度波动的影响。
  • 不要因为某个变体暂时领先就提前结束测试——均值回归是真实存在的。
  • 记录每次测试:假设、时间范围、流量分配、结果、置信度、决策。

7. CRO by Traffic Source

7. 基于流量来源的CRO优化

The same page can need completely different optimization depending on where visitors are arriving from. Design and copy for the coldest, least-informed traffic source hitting that URL.
同一页面根据流量来源的不同,可能需要完全不同的优化方案。针对访问该URL的最冷、信息最匮乏的流量来源进行设计和文案撰写。

Cold traffic (paid social, display, broad paid search)

冷流量(付费社交、展示广告、广泛匹配付费搜索)

  • Visitors have no prior awareness of the brand.
  • Must establish credibility and context immediately.
  • Longer pages perform better — more space to build trust and address objections.
  • Social proof must include recognizable reference points (logos, industries, role titles).
  • Headline: lead with the pain or problem, not the solution name.
  • 访问者对品牌无任何认知。
  • 必须立即建立可信度和上下文信息。
  • 较长的页面表现更好——有更多空间建立信任和处理异议。
  • 社交证明必须包含可识别的参考点(logo、行业、岗位头衔)。
  • 标题:以痛点或问题为核心,而非解决方案名称。

Warm traffic (retargeting, branded search, email list)

暖流量(再营销、品牌搜索、邮件列表)

  • Visitors have seen the brand at least once.
  • Skip the basic explanation — get to the compelling offer faster.
  • Shorter, more direct pages often outperform.
  • Headline can reference their prior action ("Still thinking about [product name]?").
  • Stronger urgency or specific incentive (limited-time offer, bonus content) can close the gap.
  • 访问者至少见过一次品牌。
  • 跳过基础介绍——直接展示有吸引力的优惠。
  • 更短、更直接的页面通常表现更好。
  • 标题可提及用户的过往行为(例如"还在考虑[产品名称]?")。
  • 更强的紧迫感或特定激励(限时优惠、附加内容)可促进转化。

High-intent traffic (competitor keyword search, review site referrals, pricing page direct)

高意向流量(竞品关键词搜索、评测网站引流、直接访问定价页)

  • Visitors are actively evaluating — they are in buy mode.
  • Comparison content, guarantee language, and risk reduction are highest priority.
  • Minimize steps between landing and conversion. Remove all friction.
  • Live chat or demo booking CTAs can dramatically improve conversion at this stage.
  • 访问者正在积极评估——处于购买决策阶段。
  • 对比内容、保证话术和风险降低措施是最高优先级。
  • 最小化从着陆到转化的步骤。移除所有摩擦点。
  • 实时聊天或预约演示的CTA可显著提升此阶段的转化率。

Referral and partner traffic

推荐与合作伙伴流量

  • Visitors arrive with context from the referring source. Leverage it.
  • Custom landing pages per referral source outperform generic pages by 20-40%.
  • Match the message to the referring context ("Welcome, [Partner Name] customers").

  • 访问者从推荐来源获得了上下文信息。请充分利用这一点。
  • 为每个推荐来源定制着陆页,比通用页面的转化率高20-40%。
  • 文案与推荐来源的上下文保持一致(例如"欢迎,[合作伙伴名称]客户")。

9. Response Protocol

9. 响应流程

When the user requests CRO work:
  1. Read brand context and SOSTAC (Section 0). Always. Non-negotiable.
  2. Identify the CRO domain (Section 1). Read the appropriate reference file before producing recommendations.
  3. Ask the diagnostic questions (Section 3) if the user has not already provided this information. Do not produce recommendations without knowing current CVR and traffic source.
  4. Research the page (Research Mode) using
    agent-browser
    if a URL is available. Screenshot the current state before recommending changes.
  5. Apply the universal priority framework (Section 2). Start with value proposition, not button colors.
  6. Deliver structured output (Section 5). Quick Wins first, then High-Impact, then Test Hypotheses, then Copy Alternatives.
  7. Save deliverables to
    ./brands/{brand-slug}/campaigns/cro/
    .
  8. Recommend next steps: What to ship immediately, what to test, when to review results.
当用户请求CRO工作时:
  1. 阅读品牌背景和SOSTAC文件(第0部分)。必须执行,无可协商。
  2. 确定CRO领域(第1部分)。输出建议前阅读对应的参考文件。
  3. 询问诊断问题(第3部分),若用户尚未提供这些信息。在不了解当前转化率和流量来源的情况下,请勿输出建议。
  4. 调研页面(调研模式):若提供了URL,使用
    agent-browser
    工具。在提出更改建议前先捕获当前页面的截图。
  5. 应用通用优先级框架(第2部分)。从价值主张开始,而非按钮颜色。
  6. 输出结构化内容(第5部分)。先输出快速优化项,再输出高影响力更改、测试假设、文案备选方案。
  7. 保存交付物
    ./brands/{brand-slug}/campaigns/cro/
    目录。
  8. 推荐下一步行动:立即落地的内容、待测试的内容、何时回顾结果。

When to escalate

何时升级处理

  • Significant UX redesign or new page build -- recommend involving a designer and developer; CRO brief can define the conversion requirements.
  • Paid traffic strategy (the ads sending traffic to the page) -- route to marketing-paid-ads skill.
  • Email nurture for leads captured via forms -- route to marketing-email skill.
  • SEO implications of page changes (meta, structure, content) -- route to marketing-seo skill.
  • Brand messaging or positioning questions that surface during CRO audit -- route to product-marketing-context or brand-context update.
  • 重大UX重设计或新页面搭建——建议引入设计师和开发人员;CRO brief可定义转化要求。
  • 付费流量策略(为页面引流的广告)——转至marketing-paid-ads技能。
  • 表单捕获线索后的邮件培育——转至marketing-email技能。
  • 页面更改的SEO影响(元数据、结构、内容)——转至marketing-seo技能。
  • CRO审计中出现的品牌messaging或定位问题——转至product-marketing-context或brand-context更新。
