About Linkdex

Linkdex was an enterprise-level SEO platform delivered as a Software-as-a-Service (SaaS) solution, established in London, United Kingdom in 2009. The company catered to both in-house marketing teams at large brands and the agencies that serve them, providing an integrated suite of tools for search engine optimization. The business model was subscription-based, with licensing prices starting at approximately $600 per month.

The platform's core function was to measure and improve a brand's visibility in organic search results. It offered a comprehensive set of features, including rank tracking for desktop and mobile, competitor analysis, backlink analysis, and technical site auditing. A key differentiator was its 'Entity Search' and 'Author Search Engine,' which allowed clients to identify influential authors and publications shaping consumer decisions within their market. The software provided deep data analysis, customizable reporting options compatible with Microsoft Office, and workflow management tools designed to help teams scale their SEO activities. Clients included major brands like Microsoft, Lenovo, Tui, and Virgin Atlantic.

Mark Smith joined Linkdex in 2011 and eventually became its CEO. His background includes 12 years in publishing and leading the TMN Group as CEO, overseeing significant revenue growth. Under his leadership, Linkdex gained industry recognition, winning awards for 'Best SEO Software'. The company was backed by technology investor Amadeus Capital Partners starting in 2009.

Linkdex's journey involved two significant acquisitions. In August 2016, it was acquired by ScribbleLive, a global content marketing platform, in a strategic move to merge SEO and content marketing technologies. The goal was to create an all-in-one platform bridging the operational gap between the two disciplines. Following this, in June 2018, the Linkdex assets were acquired from ScribbleLive by Analytics SEO Limited, the company behind the rival platform Authoritas. This second acquisition brought two long-time competitors together, with the intent to merge their features and data to create a more powerful, unified platform under the Authoritas brand.
