Sitelynx will aim to increase traffic to the website and selected products such as the Times Online e-paper and the crossword section through a paid-for listings and search engine optimisation programme.
The agency will be responsible for identifying which of the paid-for products run by the site are most appropriate for promotion on search engines.
Simon Christy, Times Online's marketing manager, said: "Drawing new visitors from search introduces them to our wealth of relevant content, from the A to Z of Clarkson car reviews to breaking stories on world issues. Sitelynx is the ideal search marketing choice for a tailored approach that reflects the quality of our brand, our advertisers and our target audience."
Graham Hansell, head of strategy at Sitelynx, said search engine marketing had doubled in size between 2002 and 2004 from £110m to £223m.
