What do you think about this method to gather Contact Pages from businesses for Lead Generation?

Somehow, I need to validate the idea of mass gathering all results for specific keywords and footprints for Contact Pages for any website.
Doesn't matter the TLD (.co.uk, .ca, .yoga, etc.) you will get a business listing from Google and automatically gather Emails and Phones (soon social networks). I think is better fresh data than Yellowpages or Yelp. Somehow many broke businesses and outdated data. Domains are reliable since they just expire.

It is like doing manually but you can load your Cold Email campaign to either contact for a mass quotation for services, or promote your service/product using a strategy.

Here is the tutorial on how to do this: https://leadgen.tools/blog/how-to-scrape-contact-forms-from-any-industry/
It is using custom footprints for search engines for specific routes in the URL.

How would you apply this to your business? Do you want me to do a free search for you? Just leave the industry and country your want. I will post back a Google Spreadsheet link.
