Halalgoogling.com is dreaming big, as they aim to become, "the number one search engine in the Muslim community." Simply put, the site's strict filters prevent users from accessing haram, or forbidden, content through the search engine, although according to their blog, users can do much more.
Haram literally means "forbidden," and is applied to moral and dietary guidelines for Muslims, whereas halal means "permissible."
From their blog:
Halalgoogling has a special filtering system that excludes Haram (forbidden) sites or content from the search results such as pornography, nudity, gay, lesbian, bisexual, gambling, anti-Islamic content or anything else that is Haram according to the Islamic law.
