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.

✅ Their blog was on a subdomain. Their blog content wasn’t benefiting from the authority of the main domain, limiting its impact. ✅ A lean team with limited content resources. With just a few employees, consistent high-quality content production wasn’t feasible. We had to work with what was already published. ✅ Choosing the right pages to promote. We knew backlinks would be an important factor for driving results, but we needed a strategy to make them count.
Solution
After initial links stalled, OneUp shifted to product-led content by launching free social media tools across YouTube, Facebook, Instagram, and more. We built high-authority links (DR70–90) to these tool pages for 12 months, massively boosting their reach. The tools attracted high-intent users who discovered OneUp’s paid features through strong CTAs, driving higher-quality organic traffic and stronger growth.

Failrly new startup with a new website does not show up in AI answers- where all their competitors are showing up. Their competitors are big players in their niche and their websites over the years have achieved high authority, dominate key topics, and maintain strong online presence. The startup could not be found on search for important keywords and was not mentioned at all in AI answers. The startup had a tight budget.
Solution
The startup began our unique listicle service, after 2 months began showing up in AI generated answers and accross the different LLMs. The startup reported that they began receiving leads. When they asked these leads how they found them, the leads had told them that their solution appeared as the #1 best solution on a best list. After 4 months the startup's brand was appearing in AI answers for the most important prompts their buyer personas were asking.
Result
After 4 months the startup's brand was appearing in AI answers for all important prompts their buyer personas were asking. They were cited and mentioned accross the different LLMs where thye needed to appear. Their website also started ranking on search for the most important keywords, their domain authority went from 0 to 18, and the organic traffic to their website increased over 3000%, also they reported an increase in number of leads and conversions.

Kompozit Pazari aimed to boost traffic and sales but lacked SEO fundamentals. A quick audit revealed missing redirects, poor metadata, low-value crawl targets, unoptimized images, and thin category content. We focused on improving on-site SEO, optimizing images, and enhancing category pages to increase visibility through unbranded search.
Solution
We conducted a Semrush Site Audit to fix issues like duplicate content, broken links, 404 errors, and JavaScript problems. Competitor research revealed top traffic sources and high-performing keywords, focusing on unbranded search. Position Tracking monitored keyword rankings and content visibility. Finally, toxic backlinks were removed to reduce the site’s spam score and improve SEO health.
Result
Kompozit Pazari published over 50 SEO-optimized category pages and 15+ blog posts. Despite infrastructure challenges, many technical issues were resolved through ongoing communication. As a result of consistent content efforts, visibility increased by 9.94%, conversion rate by 2.89%, transactions by 93%, and revenue by 1,188%.
