1) You enter a Google or Yahoo search term like "animal grooming in chicago IL email contact." It crawls the search results and scans each site listed for a sitemap (or manually crawls the site for inner pages). Then it lists the sites in the display window. You can manually view the list and exclude sites that are not desireable.
2) Aftter the site list is done, the "Scrape" button goes thru every page of the site listed and looks for a publicly available contact email address. It then creates 2 log files, one contaiing a detailed log of the scraping process, the other is simply a cr/lf delimited list of the emails found.
I am working on an example video that shows how I used it in reselling wholesale pet care products last Fall. I entered the searches for a lot of major cities (or whole states in some instances) and developed a list of over 2000 publicly available contact email addresses that were specific to that niche industry.
I wrote the tool because I saw that buying generic email lists cost a lot of money, and they didn't give me people that would be specifically interested in those types of products.
