Related Skills
- form-cro — WHEN the form inside the popup needs deep optimization (field count, validation, error states). NOT for the popup trigger, design, or copy.
- page-cro — WHEN the surrounding page context needs conversion optimization and the popup is just one element. NOT when the popup is the sole focus.
- onboarding-cro — WHEN popups or modals are part of in-app onboarding flows (tooltips, checklists, feature announcements). NOT for external marketing site popups.
- email-sequence — WHEN setting up the nurture or welcome sequence that fires after a popup lead capture. NOT for the popup itself.
- ab-test-setup — WHEN running split tests on popup trigger timing, copy, or design. NOT for initial strategy or design ideation.
Communication
Deliver popup recommendations with specificity: name the trigger type, target audience segment, and frequency rule for every popup proposed. When writing copy, provide headline, subhead, CTA button text, and decline text as a complete set — never partial. Reference compliance requirements (GDPR, Google intrusive interstitials policy) proactively when relevant. Load marketing-context for brand voice and ICP alignment before writing copy.
Proactive Triggers
- User mentions low email list growth or lead capture → ask about current popup strategy before recommending new channels.
- User reports high bounce rate on blog or landing page → suggest exit-intent popup as a low-friction capture mechanism.
- User is running paid traffic → recommend behavior-based or source-matched popup targeting to improve ROAS.
- User mentions GDPR or compliance concerns → proactively cover consent, opt-in mechanics, and Google's intrusive interstitials policy.
- User asks about increasing free trial signups → recommend click-triggered or scroll-depth popup on pricing/features pages before assuming acquisition is the bottleneck.

Popular marketing & seo skills
reddit-automation
flowkit-labs/skills
Find Reddit threads where people are genuinely asking for what you offer, then draft short, genuinely helpful replies — disclosing your affiliation honestly and naming your product only when it truly answers the question. Two moves: discovery — scan the right subreddits for real needs (recommendation asks, expressed pain, competitor mentions) and rank the few threads where you can actually help; drafting — write from real experience, respect each community's self-promo rules, and keep a human in the loop to review and post. This markets on Reddit the honest way: contribute value, disclose who you are, never astroturf. Distilled from the playbook behind doany.ai's Reddit agent. Triggers on "find reddit opportunities", "reddit marketing", "reddit automation", "reply on reddit for my product", "reddit community engagement", "reddit lead gen", or any ask to turn Reddit threads into genuine, disclosed marketing replies.
