The two originally signed a deal back in November 2001, when Espotting became the first paid placement service to expand beyond search into contextual advertising through a deal with Kelkoo.
The deal sees Espotting supplying its top five results as "Top Sponsored Picks" on Kelkoo categories with keywords corresponding to the relevant channels.
Espotting has worked with Kelkoo to "drill deep" in to its site beyond the main category headings, for example, Espotting's results for car insurance can be found in Kelkoo's car insurance .
Dorothea Arndt, head of marketing at Kelkoo, said: ''The expansion of the original deal is testament to its success and to our 230% year on year revenue growth. In the UK alone, revenue from the Espotting deal has increased by nearly 900% since we introduced it in 2001."
In addition to Kelkoo, Espotting has channel/contextual advertising agreements with Lycos, O2, DooYoo and La Tribune in Europe.
"Espotting's strategy has always been to reach the right person at the right time -- whether that be through search, directories, channels or wireless," Daniel Ishag, CEO and founder of Espotting Media, said. "We are constantly expanding reach for advertisers while helping websites earn from previously unmonetised site areas."
