The actor performs a crawl of web pages from a provided list of naked domain names using headless Chrome. For each web page visited, the crawler extracts and saves the following information:
- Page data:
- Page title
- List of all links
- JSON+LD linked data
- Social handles
- Emails
- Phone numbers
- Facebook profiles
- LinkedIn profiles
- Twitter profiles
- Instagram profiles
- Screenshot (if
saveScreenshot
setting istrue
). The screenshots are stored in JPEG format to save disk space. Note that taking screenshots is quite resource intensive and will slow your crawler down. - HTML content (if
saveHtml
setting istrue
) - Text body of the page (if
saveText
setting istrue
) - HTTP response headers
- Information about SSL/TLS certificate
For each domain (e.g. example.com
) from the input, the actor tries to load the following pages:
http://example.com
https://example.com
(only ifcrawlHttpsVersion
setting istrue
)http://www.example.com
(only ifcrawlWwwSubdomain
setting istrue
)https://www.example.com
(only if bothcrawlHttpsVersion
andcrawlWwwSubdomain
settings aretrue
)
Additionally, if the crawlLinkCount
setting is greater than zero, for each domain
the crawler tries to open crawlLinkCount
pages linked from the main page and analyze them too.
The crawler prefers the links that contains the /contact
text, to increase the chance it will find
more emails, phone numbers and other social handles.
The results of the crawler are stored into a dataset. For each web page crawled there is one record. The optional screenshots and HTML snapshots of web pages are stored into separate records into the key-value store.
For example, for the web page https://example.com
the resulting record in the dataset will look as follows (in JSON format):
{
"domain": "example.com",
"url": "http://example.com",
"response": {
"url": "http://example.com/",

}
If the web page cannot be loaded for any reason, the record contains the information about the error:
