UPDATE 1-Alterian says Q3 trading in line, Q4 view positive

* Revenue doubles from year-ago

* Gets new contract from Jaguar Land Rover

* Says FY revenue weighted towards Q4 (Adds details)

Jan 12 (Reuters) - Marketing software provider Alterian Plc ALN.L said on Monday its third-quarter trading was in line with its view, mainly on high renewal rates and broadened client base, and the outlook for fourth quarter was positive.

The company said third-quarter and nine-month revenue doubled from last year, in part due to the strong performance from its online products, which more than offset the slowing growth rate in revenue from the United States.

Alterian said full-year revenue to March 31 would be weighted to the fourth quarter due to the concentration of receipts under long-term contracts and renewals, and would depend to some extent on the rate of roll-out of products by its partners and the timing of contracts.

Three analysts on average were expecting the company to report a revenue of 30.9 million pounds ($46.44 million) for the year to March 31, according to Reuters Estimates.

Separately, Alterian, which delivers software to about 1,000 marketing departments across 26 countries, said it received a contract from Jaguar Land Rover to manage the automaker's global websites. Jaguar Land Rover, owned by India's Tata Motors Ltd (TAMO.BO), will use Alterian Content Management platform to support its global markets and boost sales. No financial details were given.

At 0912 GMT, Alterian shares were up 0.25 pence at 60.25 pence. ($1=.6653 Pound) (Reporting by Kumar Alagappan in Bangalore; Editing by Gopakumar Warrier)
