Crushing local SEO with 307% growth: London Sash Window
The project overview
Company: The London Sash Window Company
Location: London – Kensington, Clapham, Dulwich, Islington, Hampstead
Service Focus: Local SEO and lead generation
Duration: February 2023 – May 2024 vs. February 2024 – May 2025
The mission: Ranking higher, leading higher
The London Sash Window Company wanted more than visibility – they wanted dominance. A trusted business in the heart of London’s High Street, they sought to generate more high-quality leads, elevating them from a window solutions provider to a go-to name in heritage window restoration across London.
With a focus on organic growth, lead quality, and local authority, this campaign was designed to outperform expectations – and it did.
The challenge: A flawed foundation to deal with SEO expertise
Taking over this project meant more than optimisation — it meant unravelling years of underperformance. The company’s previous website was clearly holding them back, and we uncovered multiple roadblocks early on.
Disorganised content structure – Thin, duplicated service pages with poor keyword targeting.
Poor user experience – Page speed and mobile usability were significantly below standard.
Neglected link profile – Almost zero backlinks, low authority, and missed opportunities.
Very limited visibility – Weak rankings, minimal traffic, and no foothold in local search.
Our strategy: Merge Smart, Not Fast
We knew London’s search landscape was saturated. So, we broke it down — borough by borough, keyword by keyword. Our strategy included:
A comprehensive plan for a complex market
Bespoke location-based service pages targeting high-value areas like Dulwich, Kensington, and Clapham. We heavily focused on technical SEO to optimise speed, UX, and Core Web Vitals. A robust strategy for internal linking and fresh schema for services, reviews, and locations was crucial.
Building trust with authenticity
Our trust-building game included Google Business Profile optimisation and consistent content creation to boost local visibility. Moreover, we focused on content including reviews, case studies, and FENSA certification references.
Rebuilding authority from the ground up
We inherited a site with weak content, almost no backlinks, and limited traffic. We rewrote all service and location content with user intent in mind. We built 40+ high-authority backlinks from industry, property, and lifestyle publishers. Lastly, search-led blog content captured educational and transactional queries.
Listening to level up
One surprising insight came from call recordings — over 50% of inbound leads weren’t being handled effectively. With this intel, we delivered structured training advice to help the client’s internal team.
What changed: The results of February 2023 – May 2024 vs. February 2024 – May 2025

Why this campaign was a game changer: What worked?
But we didn’t just patch it up — we rebuilt. Our team restructured the site architecture, rewrote every key page, crafted new content, and launched a link-building strategy that gave the domain real power.
We also provided internal training on lead handling, ensuring that no opportunity was missed once users discovered the site. Here’s why this strategy stood out:
A niche service, marketed on a mainstream scale
Hyper-local SEO in one of the UK’s toughest markets
Targeted, trust-driven storytelling paired with deep technical execution
Real results with long-term growth and zero shortcuts
In short, this is a perfect example of how strategic SEO can go beyond rankings and transform a business.
