Abstract: To help advertisers to manage their online advertising, some business metric, such as ROI, profit, gross profit, etc., may be estimated and/or tracked with respect to an ad campaign, or a portion of the ad campaign. An advertiser may provide a business metric target, such as a target ROI, a target gross profit, a target profit, etc. An ad delivery system may then adjust information in an ad campaign (or a portion of an ad campaign) in an effort to meet the target. Similarly, an advertiser may provide a goal, such as maximizing or minimizing a business metric. The ad delivery system may then adjust information in an ad campaign (or a portion of an ad campaign) in an effort to meet the goal. The targets or goals may be subject to one or more constraints. The advertiser may provide limits on values of one or more business metrics. The ad delivery system may then turn off, or govern, the delivery of ads if the limits are violated.

Abstract: Methods and systems for improving user search experience with a search engine by providing a way for associated users to create and share personalized lists of local search results and/or advertisements through endorsements of such local search results and/or ads. Local search endorsements can be used to personalize the search engine's ranking of local search results by offering a way for users to re-rank the results for themselves and for those who trust them.

Abstract: A process for preparing furans of the formula (I) ##STR1## by reacting a furanone of the formula ##STR2## with an organic orthoacid or an orthosilicate in the presence of an acid catalyst at an elevated temperature.

Abstract: A process for preparing a composition of the formula ##STR1## by reacting a composition of the formula ##STR2## with a polyhydric alcohol of the formula HO--X--OH in the presence of an acid catalyst at an elevated temperature to form a ketal of the formula ##STR3## and reacting the ketal of the formula (II) with a monohydric alcohol in the presence of an acid at an elevated temperature to form ##STR4##
