Background

The Client

RankAuthority.ai – an AI-powered SEO platform for creators and small businesses. The founder had validated demand with a Bubble MVP and was running Instagram + Google Ads directly to a landing page.

But despite 300+ paid clicks, there were effectively zero free-trial sign-ups and no paying users.

Audit Findings

300+ paid clicks but effectively zero free-trial sign-ups

Non-responsive landing page (tiny text, broken mobile layout)

Vague hero copy with no clear value proposition

No social proof, screenshots, or demo video

High-friction pricing requiring credit card for trial

Half-MVP product with scattered Bubble logic

No proper subscription engine or scalable architecture

What They Needed

  • Fix the funnel so ad spend wasn't wasted
  • Re-platform RankAuthority into a real SaaS with subscriptions and usage limits
  • Ship a focused v1 fast, without hiring a full in-house tech team

Conversion & Landing Page Fix

Redesigned the funnel around one goal: get visitors into a risk-free trial

Simplified Page Architecture

Removed low-value pages and long brochure sections. Focused on three core pages: Home, Pricing, Support/FAQ.

High-Impact Hero Section

Clear benefit-driven headline, sticky mobile CTA, and 'Start Free 7-Day Trial' primary action with high-contrast button.

Product Preview & Demo

Added dashboard screenshots and embedded walkthrough demo instead of buried YouTube links.

Social Proof & Trust

Introduced testimonial slots, trust elements, logos, and early-user quotes to reduce risk perception.

Pricing Clarity & Offer Design

Clean pricing table with $40/$70 plans, clear features, limited promo for first 20 users, and 'try first, commit later' messaging.
