A new tool which enables users to test their online landing pages has been launched by search engine giant Google.

Initially available only to a limited number of advertisers, the Google Website Optimizer uses analytics technology to inform web marketers of how best to layout their landing pages to drive the maximum number of conversions.

The interface system means users can easily test a range of landing page options and decide upon the most appropriate.

It is believed the new tool could prove very useful for advertisers in optimising their conversion rate, whether this is judged on sales, sign-ups or downloads.

Google said in a statement: "Whether you define a conversion as a purchase or a newsletter sign-up, Website Optimizer allows you to experiment with different headlines, copy, and images on your site in order to find out which combination results in the most conversions."

The second Israeli Google research & development facility is soon to be opened in Tel Aviv.
