Building Scalable SEO & Marketing Platform

1. Introduction

This engagement focused on supporting Hertz as it scaled organic visibility and marketing execution across multiple markets and languages.

The work evolved over time from search optimisation into platform design and long-term marketing development, operating under tight technical constraints and global operational complexity.

The goal was not short-term rankings, but to create a system that could support sustained growth across regions without increasing dependency or friction.

2. Context

In 2011, Hertz was operating with a tightly coupled CMS that was deeply interwoven with its core systems. While stable, this setup made even basic marketing changes slow and heavily dependent on internal development teams.

As global search demand grew around regional, city, and location-based queries, the existing system struggled to support the volume and speed required to compete effectively.

Any solution had to work alongside existing infrastructure, respect internal governance, and scale across markets without introducing operational risk.

3. Problem

The core problem was not search visibility itself, but page creation velocity.

While initial SEO efforts delivered strong rankings for core “Car Rental” and “Car Hire” terms, expansion into regional and location-level search required hundreds of additional pages. The existing CMS made this process slow, manual, and dependent on the Hertz development team, resulting in turnaround times measured in months.

Compounding this, location-specific data such as opening hours, holidays, and operational updates changed frequently — making static page generation increasingly fragile.

We deliberately did not attempt to replace Hertz’s CMS or booking engine. That approach would have introduced unnecessary risk and dependency.

4. Approach

Our approach prioritised structural leverage over tactical optimisation.

Instead of pushing for incremental SEO fixes or CMS workarounds, we focused on enabling Hertz’s marketing teams to operate independently at scale. This meant designing systems that could live within existing constraints, integrate with core services through APIs, and reduce reliance on manual development cycles.

The guiding principle was simple: marketing pages should move at marketing speed, not platform speed.

5. Execution

Phase 1 — Search foundation and page expansion

We began with SEO execution, establishing strong visibility for core commercial keywords and validating demand across regions. To overcome CMS limitations, we built an internal tool that generated SEO-ready HTML pages and deployed them directly within the Hertz site structure.

This reduced page creation time from months to approximately one week and allowed the UK market to scale location and regional coverage quickly.

Phase 2 — From page generation to CMS

As location data changed frequently, regenerating static pages became inefficient. Hertz set a one-month timeline to replace the page generation tool with a CMS that could support ongoing updates. We delivered a working system within that window, enabling the transition away from static page generation.

The system:

• supported multiple markets and languages
• integrated directly with Hertz’s booking engine via APIs
• allowed marketing teams to create and update pages without development dependency

This marked a shift in responsibility, and Envigo was formally brought in as a Technology Partner.

Phase 3 — Global rollout and expansion

Following the success of the initial implementation, the platform was rolled out across European markets and later extended to additional regions. The ease of page creation led teams to migrate campaign pages and PPC landing pages into the same system, consolidating marketing execution into a single operational layer.

Phase 4 — Ongoing platform evolution

Today, Envigo supports Hertz as a preferred partner for marketing development initiatives. Recent work includes the design and rollout of an affiliate management system, currently live across seven European markets, alongside ongoing UX experimentation to improve performance and usability across touchpoints.

6. Outcome

The engagement resulted in a marketing platform that enabled Hertz to scale search visibility across regions, cities, and locations in local languages without increasing operational friction.

More importantly, it shifted how marketing execution was handled internally — from a dependency-heavy process to an independent, scalable system.

The longevity of the platform, and its continued use alongside newer enterprise tools, reflects its structural role rather than short-term performance gains.

7. Reflection

In hindsight, the most valuable outcome was not rankings or traffic, but trust.

By solving problems within constraints rather than attempting to replace core systems, we were able to take on progressively higher levels of responsibility. If repeated today, we would formalise platform extensibility even earlier, anticipating future integrations beyond SEO and campaign execution.

This engagement reinforced the importance of designing marketing systems that earn their place over time, rather than forcing adoption through disruption.
