Abstract: Code is injected into a web page loaded by an Internet browsing application. A search control to accept Internet search input is presented within an Internet browsing application. The search control visually covers at least a portion of a content display area of the Internet browsing application. A slider search control may be presented by automatically sliding the slider search control into the content display area. The presentation of a lightbox search control may include shading, darkening, dimming, blurring, or opaquing the content display area outside of the lightbox search control. The presentation of the search control may occur in response to a period of user inactivity, an amount of page scrolling, or a percentage of page scrolling. The search control receives input corresponding to a search query, a tracking code is combined with the received input, and the combination is communicated to a search engine.

Abstract: An exchange platform facilitates the transaction of goods and/or services in a local area. The exchange platform allows sellers to create sale postings for goods or services, and potential buyers to review the sale postings. Once transaction fees are paid, contact information is provided so that the buyer and seller can meet to exchange the goods or services for payment. The transaction fees can be paid using credits that are earned by viewing sponsor advertisements.
