Result

Within six months, our strategic advertising initiative generated over $250,000 in revenue, consistently maintaining a minimum of 4x Return On Ad Spend (ROAS), a testament to our methodical approach and care for optimisation throughout.

A highly esteemed dental clinic in London sought to escalate their SEO reach, striving to gain unparalleled visibility across both local and national spectrums, and to draw discerning clients from all over England to their doorstep.

Solution

Our approach involved a finely-tuned SEO campaign, concentrating a substantial portion of the budget on key dental services—primarily 'Invisalign' and 'composite bonding'. This focus was aimed at capturing and retaining top search engine rankings within these high-demand categories.

Result

The campaign's outcome was reassuringly powerful, with the clinic attaining the number one search term ranking in 26 out of 28 central London districts, thereby cementing their dominance in one of the most fiercely competitive SEO arenas worldwide within a mere twelve months.

Challenge

Madison Brook International was facing high customer acquisition costs (CAC) and inconsistent lead generation through its PPC campaigns. Their goal was to increase visibility, generate quality leads, and reduce CAC.

Solution

We focused heavily on Quality Score, decreasing CPC and improving Ad Rank, which reduced lost impression share (more traffic, less cost). We refined keywords & bids, optimised ads, and adjusted audience targeting for better-quality conversions, with continuous A/B testing for ongoing improvements.

Result

Our strategy led to a +45% increase in click-through rates (CTR), a +35% reduction in cost per conversion, and a +40% increase in conversion rate. These changes significantly boosted their lead quality and reduced their overall marketing spend.
