Challenge

Our client, a global procurement software provider, needed to increase brand awareness and lead generation in the North American market. The main challenges were the lack of a defined content strategy, the differences in users’ online behavior between continents, and slow ranking of key words.

Solution

Smartboost implemented a data-driven SEO strategy based on a predictive search ranking machine learning model to increase organic traffic through multiple SEO tactics. The goal was to get more traction from organic search to be able to generate more sustainable traffic and revenue.

Result

After 12 months, overall website traffic increased by 122%, going from 4,401 website users to 9,792. Organic traffic rose by 33%, resulting in an increase in organic lead generation by 93%.
