Naked domains analyzer

jancurn/analyze-domains

Crawls and downloads web pages running on a list of provided naked domains (e.g. "example.com"). The actor stores a HTML snapshot, screenshot, text body, and HTTP response headers of all the pages. It also extracts email addresses, phones and social handles for Facebook, Twitter, LinkedIn and Instagram.

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 is true). 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 is true)
  • Text body of the page (if saveText setting is true)
  • 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 if crawlHttpsVersion setting is true)
  • http://www.example.com (only if crawlWwwSubdomain setting is true)
  • https://www.example.com (only if both crawlHttpsVersion and crawlWwwSubdomain settings are true)

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:
