![]() ![]() The easiest way to limit the amount of googlevideo content is to identify the seeds from which googlevideos are being captured, and add seed level data limits to them. For example, a 1GB data limit on the host could result in 1GB from, 1GB from, and so on. Because googlevideo files are served from a large number of individual subdomains, adding one rule to limit the amount of Googlevideo content often isn't enough. Host level data limits apply individually to each subdomain of that host. Optional scoping rules for YouTube Scoping This issue can be addressed in the seed scope by adding the following repeating directories regular expression to Block URL if it matches the regular expression: ![]() This is the most common crawler trap that affects the host as in this example: Sometimes, YouTube crawls can run into crawler traps and archive invalid URLs with seemingly endless combinations of repeating directories. If you prefer to archive only those videos and video pages from the specific YouTube seed that you added to your collection: Ignore robots.txt for each seed. - This host serves stylesheet and JavaScript content necessary for playback.If you wish to archive YouTube videos linked or hosted by any site in the course of your crawl, you must first modify your collection's crawl scope to ignore robots.txt files from the following hosts, exactly as they appear here: To make sure that you are able to capture the look and feel of a YouTube page and/or any video content, you will therefore need to add the rules listed below.

As with channels, you may need to add a seed level data limit in order to avoid crawling excessive additional videos. We strongly recommend a test crawl when crawling search pages. YouTube search pages like "william+shakespeare" are best crawled using the One Page Plus External Links ( One Page +) seed type. Format your seed like the above - do not put a trailing slash (/) at the end.To archive a playlist index and all of the video watch pages to which it links: The URL for each playlist can be added as seed, and is typically formatted as: Playlists are specific lists of videos curated by a user from among their account's and/or other videos on YouTube. Consider using the test crawl to determine how much data you should allot to these seeds then limit your crawl by adding a data limit at the seed level. Depending on the number of videos, these seeds can be very data heavy. The Standard seed type is best for crawling the videos linked off of a channel page, however a test crawl is strongly recommended when crawling a channel for the first time. This enables our crawler to access all videos uploaded to the user's account. However, when you wish to archive a user's YouTube channel in its entirety, we further recommend adding an additional seed URL for its "Videos" tab, which is formatted as: /videos. For example, the University of Melbourne's channel can be accessed at. ![]() YouTube channels are topic-specific groups of videos and related content.

New YouTube seeds will have the default scoping rules automatically applied at the seed level when they are added to a collection.
