When you go through the process of content removal, you should always start with the easiest methods. Contacting any site hosting your content and asking them to take it down is an effective method of removing unauthorized content from the internet. This allows you more time to find other offenses, as well as building relationships allowing for the facilitation of future take-down requests.
Send an email to the site(s) in question, allowing up to 3 days for a response before continuing with the rest of the content removal steps. Almost everyone wants to do this the easy way and it will be faster than any other option available.
Send email to whois contact information for the site in question (allow 1 or 2 days)

Send DMCA directly to the site if they have a link available, or via Google through their DMCA takedown process. Please see our article on the sending DMCAs directly to Google.
Remember that Google will remove links and images once they realize the page has been deleted without any action from you. This process can take either days or weeks depending on when Googe processes the request.
