Real Results: Case Studies

📈 Case Study 1: E‑Commerce Site

Client: A mid‑sized online retailer selling eco‑friendly products.

Challenge: The site had 15,000+ products but suffered from poor organic traffic and low conversion rates.

Solution: We ran a full site audit using our toolkit, identifying 300+ broken links, missing alt texts, and slow page speed. The AI assistant prioritised fixes and generated schema for every product page.

Result: Within 3 months, organic traffic increased by 78%, and revenue from organic search doubled.

📝 Case Study 2: Content Publisher

Client: A lifestyle blog with 200+ articles.

Challenge: Content was well‑written but not ranking for target keywords due to low topical authority.

Solution: We used the Topical Authority Score and Keyword Cannibalisation Checker to reorganise content silos.

Result: Search impressions grew by 145% in 60 days, and the blog achieved 8 featured snippets.
