Enhancements to adaptive bit rate techniques are described that relate to selection of the initial bit rate with which video content is delivered. The bandwidth available to a client device is estimated by determining the time required by the client device to download a specific amount of content, e.g., the 'above-the-fold' portion of a requested web page. An initial bit rate is selected for video content associated with the page that is within the estimated available bandwidth.

Aspects of connected phrase search queries and titles are described. In one embodiment, a phrase in a search string may be identified with reference to a compilation data store. The compilation data store may include various collaborative, taxonomy, and brand name data, for example. After a phrase is identified in the search string, a search query may be generated based on the phrase. For example, a catalog of items may be queried to generate a query result, and the query result may be parsed for display to a user. In various embodiments, a plurality of phrases may be identified in a search string, and a plurality of search queries may be generated based on combinations of the phrases. In this manner, more search results may be obtained, especially for constrained search strings. The identification of phrases may also be applied to generate variations on titles, in certain embodiments.

Techniques for determining and providing a preferred layout of a network page may be provided. For example, the system may receive a query with a keyword, access data regarding previous users' interactions associated with the results of the keyword, determine a category associated with the interactions, and provide a display (e.g., on the original network page) for that particular category. In some examples, the system may provide generic network pages and item- or category-specific network pages associated with a particular layout or presentation characteristics. The system can identify the presentation characteristics of the category-specific network page and incorporate them with the generic network page, without redirecting the user to the category-specific network page.
