The Amadeus Seed Fund led the investment, its sixth in three years, with participation from Amadeus III.

Laurence John, CEO of Amadeus Seed Fund, says, ‘We are backing Linkdex because they’ve identified solutions for the current road blocks in web transparency for online marketers.’

John adds that the fund ‘is building its portfolio through this downturn so that as we come through it we have some maturing assets to bring to market’.

Based in London and San Francisco, Linkdex aims to help companies analyse the process by which search engines deliver their results and achieve higher rankings in natural (non-paid-for) search for their brands and services.

Linkdex CEO John Straw claims, ‘[Our databases] have created a web map of over one trillion links, to identify why some web pages are more authoritative and relevant than others.’
