Content pre-render and pre-fetch techniques
Content pre-render and pre-fetch techniques are described. In one or more implementations, a likelihood is predicted of subsequent navigation to content associated with a network address based at least in part on monitored navigation performed by a computing device to one or more network addresses. A determination is then made whether to cause the computing device to pre-fetch and pre-render the content based at least in part on the prediction.
1. A method comprising:
predicting a likelihood of subsequent navigation to content associated with a network address based at least in part on:
monitored navigation performed by a computing device to one or more network addresses; and
computing a confidence score; and
determining whether to cause the computing device to pre-fetch and pre-render the content based at least in part on the prediction and comparing the confidence score to one or more thresholds and by at least one of:
responsive to a determination that the confidence score meets a pre-render threshold for the subsequent navigation, causing the content associated with the network address to be pre-fetched and pre-rendered by the computing device; or
responsive to a determination that the confidence score meets a pre-fetch threshold for the subsequent navigation but does not meet the pre-render threshold for the subsequent navigation, causing the content associated with the network address to be pre-fetched but not pre-rendered by the computing device.
2. A method as described in claim 1 , wherein the one or more network addresses are a current network address accessed by the computing device.
3. A method as described in claim 1 , further comprising pre-fetching and pre-rendering the content responsive to a comparison of the confidence score with a pre-render threshold that is indicative of the likelihood of subsequent navigation to the content.
4. A method as described in claim 3 , wherein:
the pre-fetching includes obtaining the content from the network address; and
the pre-rendering includes parsing an HTML and running dynamic scripts of the obtained content to arrive at a form of the content that is ready for display by a display device of the computing device.
5. A method as described in claim 4 , wherein the pre-rendering is performed in associated with a tab in a user interface that is not visible to a user and further comprising replacing content of a currently viewable tab with the rendered content in the tab responsive to an input to navigate to the network address.
6. A method as described in claim 1 , wherein the pre-fetch threshold is indicative of a lower likelihood of the subsequent navigation than a pre-render threshold.
7. A method as described in claim 1 , wherein the predicting is performed using one or more rules including a rule configured to identify a particular sequence of monitored navigation performed by the computing device at one or more network addresses.
8. A method as described in claim 1 , wherein at least one of the rules is configured to identify a type of link included in content to be used as a basis for the prediction but not a particular network address associated with the link.
9. A method as described in claim 1 , wherein the one or more rules are received from a network service, the one or more rules generated based on data described monitored navigation performed by a plurality of different computing devices.
10. A method as described in claim 1 , wherein the monitored navigation describes a sequence of network addresses that have been accessed by the computing device.
11. A method as described in claim 1 , wherein the predicting and the determining are performed locally by the computing device.
12. A method as described in claim 7 , wherein at least one of the rules is configured to identify that multiple links are associated with a same network address.
13. A system comprising:
one or more processors; and
one or more computer readable storage media storing program instructions that are executable by the one or more processors to perform operations comprising:
computing a confidence score indicating a relative likelihood of subsequent navigation to content associated with a network address based at least in part on monitored navigation performed by a computing device to one or more network addresses;
responsive to a determination that the confidence score meets a pre-render threshold for the subsequent navigation, causing the content associated with the network address to be pre-fetched and pre-rendered by the computing device; and
responsive to a determination that the confidence score meets a pre-fetch threshold for the subsequent navigation but does not meet the pre-render threshold for the subsequent navigation, causing the content associated with the network address to be pre-fetched but not pre-rendered by the computing device.
14. A system as described in claim 13 , wherein the computing is performed using one or more rules that is configured to identify a type of link included in content to be used as a basis for the prediction but not a particular network address associated with the link or are generated based on data described monitored navigation performed by a plurality of different computing devices.
15. A system as described in claim 13 , wherein:
the pre-fetching includes obtaining the content from the network address; and
the pre-rendering includes parsing an HTML and running dynamic scripts of the obtain content to arrive at a form of the content that is ready for display by a display device of the computing device.
16. A system as described in claim 13 , wherein the one or more processors are accessible via a network by the computing device.
17. A system comprising:
one or more processors; and
one or more computer readable storage media storing program instructions that are executable by the one or more processors to perform operations comprising:
generating navigation data based on monitored navigation performed by a plurality of different computing devices to access a plurality of different network addresses, the navigation data including one or more rules that include a rule configured to identify a type of link included in content to be used as a basis for the prediction but not a particular network address associated with the link; and
exposing the navigation data for use by a computing device to predict subsequent navigation by the computing device to one or more network addresses, at least part of the predicted navigation not involving a link included in a current content item accessed by the computing device.
18. A system as described in claim 17 , wherein one or more rules included in the navigation data further include a rule generated based on data describing monitored navigation performed by a plurality of different computing devices.
19. A system as described in claim 17 , wherein the prediction of the subsequent navigation by the computing device is performed as part of a determination of whether to pre-render content associated with the subsequent navigation by the computing device.
20. A system as described in claim 17 , wherein the prediction of the subsequent navigation by the computing device is performed as part of a determination of whether to pre-fetch content associated with the subsequent navigation by the computing device.
21. A system as described in claim 17 , wherein the one or more rules included in the navigation data further include a rule generated based on data describing content obtained via at least one of the plurality of network address.
