Crawl Workflow Setup¶
The first step in creating a new crawl workflow is to choose what type of crawl you want to run. Crawl types are fixed and cannot be converted or changed later.
- The crawler visits every URL specified in a list, and optionally every URL linked on those pages.
- The crawler automatically discovers and archives pages starting from a single seed URL.
List of URLs¶
This list informs the crawler what pages it should capture as part of a URL List crawl.
It is also available under the Additional URLs section for Seeded Crawls where it can accept arbitrary URLs that will be crawled regardless of other scoping rules.
Include Any Linked Page¶
When enabled, the crawler will visit all the links it finds within each page defined in the List of URLs field.
Crawling tags & search queries with URL List crawls
This setting can be useful for crawling the content of specific tags or search queries. Specify the tag or search query URL(s) in the List of URLs field, e.g:
https://example.com/search?q=tag, and enable Include Any Linked Page to crawl all the content present on that search query page.
Fail Crawl on Failed URL¶
When enabled, the crawler will fail the entire crawl if any of the provided URLs are invalid or unsuccessfully crawled. The resulting archived item will have a status of "Failed".
Crawl Start URL¶
This is the first page that the crawler will visit. It's important to set Crawl Start URL that accurately represents the scope of the pages you wish to crawl as the Start URL Scope selection will depend on this field's contents.
You must specify the protocol (likely
https://) as a part of the URL entered into this field.
Start URL Scope¶
Hashtag Links Only
This scope will ignore links that lead to other addresses such as
example.com/pathand will instead instruct the crawler to visit hashtag links such as
This scope can be useful for crawling certain web apps that may not use unique URLs for their pages.
Pages in the Same Directory
- This scope will only crawl pages in the same directory as the Crawl Start URL. If
example.com/pathis set as the Crawl Start URL,
example.com/path/path2will be crawled but
Pages on This Domain
- This scope will crawl all pages on the domain entered as the Crawl Start URL however it will ignore subdomains such as
Pages on This Domain and Subdomains
- This scope will crawl all pages on the domain and any subdomains found. If
example.comis set as the Crawl Start URL, both pages on
subdomain.example.comwill be crawled.
Custom Page Prefix
- This scope will crawl all pages that begin with the Crawl Start URL as well as pages from any URL that begin with the URLs listed in
Extra URL Prefixes in Scope
Only shown with a Start URL Scope of
Pages on This Domain and above, the Max Depth setting instructs the crawler to stop visiting new links past a specified depth.
Extra URL Prefixes in Scope¶
Only shown with a Start URL Scope of
Custom Page Prefix, this field accepts additional URLs or domains that will be crawled if URLs that lead to them are found.
This can be useful for crawling websites that span multiple domains such as
Include Any Linked Page ("one hop out")¶
When enabled, the crawler will visit all the links it finds within each page, regardless of the Start URL Scope setting.
This can be useful for capturing links on a page that lead outside the website that is being crawled but should still be included in the archive for context.
Check For Sitemap¶
When enabled, the crawler will check for a sitemap at /sitemap.xml and use it to discover pages to crawl if found. It will not crawl pages found in the sitemap that do not meet the crawl's scope settings or limits.
This can be useful for discovering and capturing pages on a website that aren't linked to from the seed and which might not otherwise be captured.
The exclusions table will instruct the crawler to ignore links it finds on pages where all or part of the link matches an exclusion found in the table. The table is only available in URL List crawls when Include Any Linked Page is enabled.
This can be useful for avoiding crawler traps — sites that may automatically generate pages such as calendars or filter options — or other pages that should not be crawled according to their URL.
Will perform simple matching of entered text and exclude all URLs where matching text is found.
example.com/aboutme/will not be crawled.
Regular expressions (Regex) can also be used to perform more complex matching.
example.com/about/will not be crawled however
example.com/aboutme/will be crawled.
Adds a hard limit on the number of pages that will be crawled. The crawl will be gracefully stopped after this limit is reached.
Crawl Time Limit¶
The crawl will be gracefully stopped after this set period of elapsed time.
Crawl Size Limit¶
The crawl will be gracefully stopped after reaching this set size in GB.
Increasing the amount of crawler instances will speed up crawls by using additional browser windows to capture more pages in parallel. This will also increase the amount of traffic sent to the website and may result in a higher chance of getting rate limited.
Page Load Timeout¶
Limits amount of elapsed time to wait for a page to load. Behaviors will run after this timeout only if the page is partially or fully loaded.
Limits amount of elapsed time behaviors have to complete.
Auto Scroll Behavior¶
When enabled, the browser will automatically scroll to the end of the page.
Delay Before Next Page¶
Waits on the page for a set period of elapsed time after any behaviors have finished running. This can be helpful to avoid rate limiting however it will slow down your crawl.
Sets the Browser Profile to be used for this crawl.
Crawler Release Channel¶
Sets the release channel of Browsertrix Crawler to be used for this crawl. Crawls started by this workflow will use the latest crawler version from the selected release channel. Generally "Default" will be the most stable, however others may have newer features (or bugs)!
This setting will only be shown if multiple different release channels are available for use.
Block Ads by Domain¶
Will prevent any content from the domains listed in Steven Black's Unified Hosts file (ads & malware) from being captured by the crawler.
Sets the browser's user agent in outgoing requests to the specified value. If left blank, the crawler will use the browser's default user agent.
Sets the browser's language setting. Useful for crawling websites that detect the browser's language setting and serve content accordingly.
Crawl Schedule Type¶
Run Immediately on Save
- When selected, the crawl will run immediately as configured. It will not run again unless manually instructed.
Run on a Recurring Basis
- When selected, additional configuration options for instructing the system when to run the crawl will be shown. If a crawl is already running when the schedule is set to activate it, the scheduled crawl will not run.
- When selected, the configuration options that have been set will be saved but the system will not do anything with them unless manually instructed.
Set how often a scheduled crawl will run.
Sets the day of the week for which crawls scheduled with a
Weekly Frequency will run.
Sets the date of the month for which crawls scheduled with a
Monthly Frequency will run.
Sets the time that the scheduled crawl will start according to your current timezone.
Also Run a Crawl Immediately On Save¶
When enabled, a crawl will run immediately on save as if the
Run Immediately on Save Crawl Schedule Type was selected, in addition to scheduling a crawl to run according to the above settings.
Allows a custom name to be set for the workflow. If no name is set, the workflow's name will be set to the Crawl Start URL. For URL List crawls, the workflow's name will be set to the first URL present in the List of URLs field, with an added
x represents the total number of URLs in the list.
Leave optional notes about the workflow's configuration.
Apply tags to the workflow. Tags applied to the workflow will propagate to every crawl created with it at the time of crawl creation.
Search for and specify collections that this crawl workflow should automatically add content to as soon as crawling finishes. Canceled and Failed crawls will not be automatically added to collections.
