Case Study: Essential Marketer

Building a 1,700-Page SEO Website Using AI, Automation and Advanced WordPress Engineering

Essential set out to create one of the most comprehensive SEO and PPC knowledge ecosystems ever built for a marketing agency website. The objective was to dominate search visibility by covering every possible topic, subtopic, query and intent pathway a user might explore.

The result was a 1,700-page WordPress website, powered by over 1 million words of AI-assisted content, all structured through Advanced Custom Fields and imported automatically with full metadata, navigation menus and internal linking. This project is now the blueprint for a scalable, productised service that can be delivered to other businesses looking to build large, search-led digital assets at speed.

The Challenge

Essential needed a website that reflected the true depth of expertise in SEO and PPC.
But ranking competitively in these industries requires more than a standard brochure site. It demands:

– Complete topical coverage
– Thousands of supporting keywords
– Pages that answer every possible question
– Semantic depth across all subtopics
– Fast production at scale

Building this manually would take years of planning, writing and development.
We wanted to achieve it in weeks.

So we created a system: an AI-driven content and automation engine capable of generating and deploying hundreds of optimised pages at unprecedented speed.

Our Approach

Mining the Entire Keyword Landscape

We extracted around 20,000 SEO and PPC keywords from Google Ads to understand every commercial, informational and long-tail search term relevant to the industry.

Using AI to Categorise Every Keyword

ChatGPT grouped the keywords into clear themes, allowing us to build a logical SEO structure and identify around 450 core pages needed to cover the topic fully.

Turning Keyword Clusters Into Page Structures

Each theme was shaped into a page plan with defined intent, keywords, purpose and URL structure, forming the foundation of the site’s content hierarchy.

AI-Generated Content for Every Page

AI produced complete, SEO-ready content for all 450 pages, following consistent structure, clear explanations and natural keyword usage.

Adding FAQs and Key Insights for Depth

We expanded each page with five common questions and five key insights to strengthen authority and improve long-tail search visibility.

Structuring Over 1 Million Words Into Spreadsheets

All content and metadata were organised into a detailed spreadsheet system, enabling accurate import mapping and automated population.

Developing a Custom WordPress Framework

We built a WordPress site using Advanced Custom Fields to create scalable, consistent templates and an SEO-friendly structure for thousands of pages.

Bulk Importing 1,700+ Pages Automatically

Using an import tool, we deployed more than 1,700 pages, complete with metadata and navigation, turning the full content plan live in a single automated process.

The Outcome

A fully deployed, content-rich website with:

1,700+ live pages

More than 1,000,000 words published

Complete topical coverage of SEO and PPC

Automated metadata and navigation creation

A scalable WordPress framework

A search-optimised structure ready for long-term growth

A new internal capability
