What it does

Conversion Optimization is an agent skill from kostja94/marketing-skills. When the user wants to improve conversion rates, run A/B tests, optimize funnels, or reduce friction. Also use when the user mentions "CRO," "conversion rate optimization," "A/B test," "split test," "funnel optimization," "checkout optimization," "form optimization," or "conversion funnel." For pricing psychology, use pricing-strategy.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering Conversion rate optimization and A/B testing. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.

When your agent uses it

  • Wants to improve conversion rates
  • Optimize funnels
  • Reduce friction
  • The user mentions CRO

Example prompts

  • “conversion rate optimization,”
  • “A/B test,”
  • “split test,”
  • “/conversion-optimization”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Funnel stage: Awareness, consideration, decision, post-purchase
  2. Conversion goal: Signup, purchase, download, demo request
  3. Traffic: Volume; mobile vs desktop split
  4. Current conversion rate: Baseline for improvement

What it can do on your machine

Read from SKILL.md and the folder at commit 8dd89c5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Conversion Optimization loads about 1.2k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 483 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~90
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Strategies: Conversion Optimization

Guides conversion rate optimization (CRO): increasing the percentage of visitors who complete desired actions. Higher conversion rates mean increased revenue, reduced CAC, and better ROI. Use this skill when optimizing funnels, running experiments, or reducing friction on high-traffic pages.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Initial Assessment

Project context: Read root contextus.md when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.

Identify:

  1. Funnel stage: Awareness, consideration, decision, post-purchase
  2. Conversion goal: Signup, purchase, download, demo request
  3. Traffic: Volume; mobile vs desktop split
  4. Current conversion rate: Baseline for improvement

CRO Process

StepAction
1. ResearchMap funnel; identify high-traffic, low-conversion pages
2. HypothesizeForm testable hypothesis (if X, then Y because Z)
3. PrioritizeScore by Potential, Importance, Ease (PIE)
4. TestA/B or multivariate; adequate sample size
5. AnalyzeStatistical significance; implement winner

PIE Prioritization Framework

Score each test idea 1–10:

FactorQuestion
PotentialHow much improvement is possible?
ImportanceHow much traffic does this page get?
EaseHow easy to implement?

Rank backlog by total score; run highest-impact tests first.

A/B Testing Best Practices

PracticeGuideline
Sample sizeCalculate minimum before launch; 95% significance without adequate sample = false positives
DurationRun full week cycles; account for day-of-week effects
One variableTest one element per experiment (or use MVT for multiple)
Mobile separateMobile converts ~50% of desktop; test mobile independently—thumb reach, form complexity differ
Low trafficUse Bayesian testing for faster, actionable results

Key Testing Areas

Page TypeTest Ideas
HomepageSearch bar prominence; personalized content; hero CTA; social proof placement
Landing pageHeadline; form length; CTA copy; above-fold layout
Product/CategoryQuick view; descriptions; add-to-cart placement
CheckoutForm fields; progress indicator; trust badges; guest checkout
PricingPlan order; anchoring; CTA per tier

Personalization: Personalized experiences generate ~41% more impact than generic ones.

Commercialization Infrastructure

ModulePurpose
Data & BIData warehouse; user behavior events; agile surveys
A/B testingExperiment platform; statistical significance; backend-controlled variants
User educationHelp docs (multi-language); update notifications; EDM
AttributionAd pixels; attribution model; impression-to-click-to-sale tracking

Avoid: Intrusive interstitials; popups that block content. Prefer non-intrusive ad formats.

Foundational Requirements

  • Analytics: Map funnels; identify drop-off points (analytics-tracking, traffic-analysis)
  • Qualitative: Heatmaps, session recordings, user tests—understand why drop-off occurs
  • Technical: Dedicated resources for 2–4 tests/month; maintain momentum

Output Format

  • Funnel map (stages, conversion rates, drop-off)
  • Hypothesis (if X, then Y because Z)
  • Test plan (variant, metric, sample size, duration)
  • Implementation checklist
  • landing-page-generator: Landing page structure and copy
  • cta-generator: CTA design and placement
  • analytics-tracking: GA4, events, conversion tracking
  • traffic-analysis: Attribution, funnel analysis
  • copywriting: Headline, CTA copy for tests
