Abstract: A social networking system permits users to store content presented by the social networking system and subsequently access the stored content associated with the users. A content item is stored in association with a user profile of a user that stored the content item and with one or more rules specifying criteria causing presentation of the stored content item to the user when satisfied. Additionally, a rule associated with a stored content item may specify a format in which the stored content item is presented when criteria associated with the rule are satisfied. When characteristics associated with a user satisfy criteria associated with a rule associated with a stored content item, the stored content item is included in a selection process determining content that is presented to the user.

Abstract: An advertiser can request that an advertising system track the advertiser's advertising campaign (“ad campaign”), which includes advertisements that share similar advertisement content, timeframe, or budget. The advertising system can track users' interactions with the advertisements of the ad campaign by incorporating click tags that redirect the user through the advertising system before directing them to the landing page of the advertisement. When a user is redirected through the advertising system by a click tag, the advertising system can log an impression in association with the advertisement contain the click tag. The impressions can then be associated with an identity of the user that is defined outside of the ad campaign and can thus be used to link impressions across different ad campaigns.
