Generate and rank landing page headlines with GPT-4o-mini, Google Sheets and Gmail

Description

Submit your landing page URL, current headline, conversion goal, and target audience using a simple form and the workflow does the rest. It scrapes your page, cleans the content, and sends everything to GPT-4o-mini which generates 10 headline variations — each using a different psychological framework such as benefit-led, pain-led, curiosity, urgency, and social proof. Every headline is scored on four dimensions and ranked by test priority. All 10 are logged to Google Sheets and a Gmail report groups them by priority with specific testing tips, ready to hand straight to your developer. Built for marketers, growth teams, and conversion specialists who want data-driven headline options without spending hours writing them manually.

What This Workflow Does

- Scrapes the landing page for real context — Fetches the actual page content so GPT generates headlines grounded in your real copy and offer — not generic variations - Generates 10 headlines across 10 frameworks — Each variation uses a different psychological approach: benefit-led, pain-led, curiosity, social proof, specificity, urgency, before and after, question, bold claim, and FOMO - Scores every headline on four dimensions — Clarity, emotional pull, specificity, and SEO fit are each rated 1–10 and averaged into an overall score - Assigns test priority automatically — The two strongest headlines are marked "Test First", the next three "Test Second", the next three "Test Third", and the remaining two "Lower Priority" - Logs all 10 headlines to Google Sheets — Each headline gets its own row with framework, copy, all four scores, priority label, and submission details - Sends a Gmail report grouped by priority — The email organises all 10 headlines into priority sections with a testing tip per headline and step-by-step instructions for running the A/B test
