The overview

A data-driven platform that replaces SEO guesswork with precise investment decisions. It models keyword difficulty, position-specific CTR curves, backlink costs, and conversion metrics to project exactly what an SEO investment will return. Built for teams and agencies managing multiple client projects.

01

The Gap

SEO investment decisions are hard to justify. Businesses spend thousands on link building and content without clear visibility into expected returns. Traditional ROI calculations ignore crucial variables like keyword difficulty tiers, position-specific CTR curves, and the compounding cost of backlink acquisition at scale.

02

Core Capabilities

Real CTR Data

Position-specific click-through rates for accurate traffic modelling across all ranking positions

Bulk Rankings

Fetch up to 1,000 ranked keywords in a single API call with automatic data refresh

7-Day Cache

Intelligent caching layer that minimises API costs while keeping data fresh

Multi-Scenario

Compare different SEO strategies side-by-side with full financial projections

03

ROI Projection Engine

Users import keywords via CSV or paste, the system fetches current rankings, then models traffic uplift from current to target positions using real CTR data. Backlink cost estimation factors in keyword difficulty to calculate required link investment. The result is a financial projection showing traffic gains, total investment, and expected revenue.

04

Multi-Tenancy & Collaboration

Organisation-based account structure with Owner and Member roles. Projects can be shared with granular permissions, and a team invitation system streamlines onboarding. Stripe handles subscription billing with a 14-day free trial requiring no credit card.

05

Technical Foundation

React 18 with TypeScript frontend, Supabase backend with PostgreSQL and 8 edge functions handling keyword analysis, rank tracking, and Stripe payments. Row Level Security enforces strict multi-tenant data isolation across 11+ tables.

The scenario planning feature changed how we pitch SEO retainers. Being able to show clients three different investment tiers with projected returns made closing deals dramatically easier.

The strategic takeaway

What this work demonstrates

The value is not the volume of activity. It is the quality of the decisions the work makes possible.

Client feedback

What clients say about working with me

Independent feedback from consulting, SEO, content and strategy engagements.

I worked with Rob to bring to life a strategy that required seven SEO-focused industry pieces for a three-month campaign. Rob provided all my copy, as well as well written meta descriptions and image tags. The result for me was a reduced spend and an increased ROI with site traffic up 33% across the campaign, so I would be happy to recommend him.
