How it works

From ad to personalized page in four steps

Set up once. Adfit handles the rest — turning your existing ads into tailored on-page experiences.

  1. 01

    Add one snippet

    Drop a single lightweight script into your site's <head>. It loads from our first-party proxy — fast, reliable, and ad-blocker resistant.

  2. 02

    Upload your ads

    Bring the ad creatives you already run — PDF, CSV, XLSX, or images. No tagging, no spreadsheets to maintain.

  3. 03

    AI builds personas & variants

    Claude analyzes each ad — audience, promise, tone — and turns it into reusable personas, then generates the on-page changes to match.

  4. 04

    Serve & measure the lift

    A token in your ad URL serves the right variant. Built-in A/B testing proves the conversion lift, variant vs. control.

Why Adfit

Message match at scale — without rebuilding anything

Everything you need to make every visitor feel like the page was written for them.

  • Message match, automatically

    The page finally delivers on the ad's promise — headline, CTA, body, and images rewritten to fit the click. For every ad, not just your top one.

  • No rebuild, no new pages

    Adfit personalizes your existing site in place with an element picker and inline edits. It's not a page builder — your funnel stays exactly one funnel.

  • First-party, ad-blocker resistant

    The snippet ships from our own first-party proxy with a minimal footprint, so it loads fast and keeps working where third-party scripts get blocked.

  • No flash of original content

    Anti-FOOC rendering means visitors never see the un-personalized version flicker before the match kicks in.

  • AI does the heavy lifting

    Upload your ads and Adfit returns structured personas plus ready-to-review personalizations — and can even map them onto your other subpages.

  • Prove the lift

    Holdback-based A/B testing with conversion goals (click, form submit, scroll, custom event) shows variant vs. control with a clear winner.

  • Built for teams & agencies

    Multi-tenant workspaces with roles (Owner, Editor, Viewer) keep every client and campaign cleanly separated.

  • Privacy by design

    EU-grade data protection is built in, with GDPR self-service export and deletion for your account.

A/B testing built in

Don't guess the lift. Prove it.

Every personalization runs as a controlled experiment. A statistical holdback keeps a slice of traffic on the original, so the conversion difference you see is real — not a hunch. Adfit calls the winner when the data is ready.

  • Holdback control group, automatically
  • Goals: click, form submit, scroll depth, or custom event
  • Clear variant-vs-control reporting with a winner

Questions, answered

Everything you might want to know before you drop in the snippet.

Adfit is an AI-powered website personalization tool. It reads the ads you're already running, builds reusable audience personas from them, and rewrites your existing landing page to match the visitor behind each click — then proves the conversion lift with built-in A/B testing.

No. Adfit personalizes your existing pages in place using an element picker and inline edits — headlines, CTAs, body text, images, and forms. There are no new pages, no duplicate funnels, and no visual page builder to learn.

You add one lightweight script to your site's <head>. It's served from our own first-party proxy, so it loads quickly, stays resilient to ad blockers, and applies personalizations before the page renders — so visitors never see the original content flash.

Yes. Adfit is built privacy-by-design and privacy-by-default. Your data is handled to EU standards, and your account includes self-service data export and deletion.

The snippet runs on Static HTML, WordPress, Webflow, Framer, and Shopify, and works across the current major versions of Chrome, Firefox, Safari, and Edge.

Each personalization runs with a statistical holdback — a slice of traffic stays on the original as a control group. Adfit measures your chosen conversion goal (click, form submit, scroll depth, or a custom event) for variant vs. control and indicates the winner once the data supports it.

PDF, CSV, XLSX, and image files. Adfit's AI reads each creative to extract the audience, promise, and tone, then turns that into structured personas and personalization suggestions.
