is it possible to scrape this phone number (opens up with a click on "ver telefono") http://www.hazmeprecio.com/empresa/wwwcastshinecom
Not at the moment. SeoTools scrapes what exists on the page when it loads. The phone number is generated after the user clicks the button.
I found a way:
A2 extracts the id of the site, A3 concatenates the id to the "get phone" url, and A4 actually retrieves the phone from the url. Of course you can combine those formulas to save some space.
