# Growth and conversion

Popups, countdowns, social proof and reviews that turn visits into signups and sales.

## Apps

- [Popups](/apps/popups.md) (beta): Popups, slide-ins, top and bottom bars, welcome mats, inline offer boxes and floating tabs that match your site, collect signups through your existing forms, and show exactly when and to whom you choose, with results and A/B tests. (Cloudflare free plan; $19 USD per site · $59 USD for all your sites)
- [Reviews](/apps/reviews.md) (beta): Collect, moderate and show customer reviews and testimonials on your own site: a review form with spam protection, personal review-request links, an inbox, lists, a wall of love, carousels and star badges that match your site, and optional Google star markup for products. (Cloudflare free plan; $19 USD per site · $59 USD for all your sites)
- [Countdown Timers](/apps/countdown.md) (beta): Countdown timers that match your site: a sale that ends on a date, a personal offer window per visitor (for example 24 hours from their first visit) for offers that really end, or a daily cutoff. Add them anywhere on a page, or inside popups and bars, and choose what happens when time is up. (Cloudflare free plan; $7 USD per site · $21 USD for all your sites)
- [Social Proof](/apps/proof.md) (beta): Small notifications of real recent activity ("Someone in Canada just signed up", "12 people joined the waitlist today") from your own forms, waitlist, reviews and link clicks. Real events only, anonymised, hidden when activity is low. (Cloudflare free plan; $7 USD per site · $21 USD for all your sites)

## Do-it-yourself playbooks

- [A/B test a page on Cloudflare Workers with no flicker (HTMLRewriter)](/playbooks/ab-testing-workers-no-flicker.md): Split visitors between two versions of a page at the edge, with a sticky assignment, no flash of the original, a consent switch, and conversions counted in D1. Works on Workers with static assets and on Pages Functions.
- [Collect and show customer reviews that build trust (and stay within Google's and the FTC's rules)](/playbooks/collect-show-reviews-google-ftc-rules.md): A review system for your own site that visitors believe: who to ask and when, what you may and may not do under the FTC's review rule and Google's policies (no fake, bought or cherry-picked reviews), how to moderate without suppressing criticism, where to show reviews, and when Google will and won't show stars. Includes the Product review markup Google accepts.
- [Email signup popups that grow your list without hurting SEO or accessibility](/playbooks/email-signup-popups-without-hurting-seo.md): What makes an email popup earn signups instead of annoying people: the offer, timing, how often it shows, how it behaves on phones, what Google says about intrusive interstitials, keyboard and screen-reader access, and consent. Includes a minimal accessible popup with the native dialog element, and the list of what's hard to get right on a real site.
- [How to vibecode an affiliate site on Next.js (and host it free on Cloudflare)](/playbooks/vibecode-affiliate-site-nextjs.md): Build a whole affiliate site with an AI coding agent, start to finish: pick a niche you can win, plan the pages that earn (best-of lists, comparisons, reviews), set up Next.js as a static export, write content Google rewards, get the SEO basics right, deploy on the Cloudflare free plan, then monetise with affiliate links and an email list, and measure which pages make money. With prompts you can give your agent at each step.
