Google Inc., the search engine company, said yesterday that it would disclose to advertisers the number of clicks on ads that it deems are invalid in a bid to assuage concerns over “click fraud.”

A Google business product manager, Shuman Ghosemajumder, said advertisers could now see how many clicks on ads are excluded from their bills.

An analyst at the market research firm JupiterKagan, Sapna Satagopan, said Google was responding to the demands of advertisers for more information on the effectiveness of their ads. Companies or individuals using special software can click on an ad repeatedly to artificially increase the marketing costs of a rival or to increase their own ad revenue.

Google sells ads using an online auction in which clients bid for certain search keywords. Companies pay each time users click on their ads, which appear next to search results.
