Google Search Console
Google Search Console (formerly Google Webmaster Tools) is a free web service by Google for webmasters allowing you to submit sitemaps, check the indexing status, and optimize the visibility of your websites.
This project involved copying the sites to a quarantine area on our server, removing malicious code, database repair, restoring core Joomla and extension code, updating the Joomla version and all extensions, and migrating the sites to an adequate host.
Completed this project in an exemplary fashion. Their organization, professionalism and adherence to best-practice web design has ensured that I would recommend them to anyone looking for assistance with a future website project.
