The best search engine there is, when all considerations are taken into account. The built-in enabled by default safesearch settings are pretty effective, almost perfect, which is why I rate this site as suitable for children on the basis that this setting is left on and the proper controls to ensure it is not turned off are in place. Now for the bad. Google and it's parent company Alphabet have been sickeningly milking the surveillance capitalistic system for decades, selling our data to the highest bidder, and developing obscenely sophisticated algorithms that can accurately predict human behaviour, emotion, and feelings to the point that it is simply just frightening. They lose two stars for being one of the most unethical tech giants on the planet. The near future will soon tell whether they get reduced to one.
google.com.au is an official domain owned by Google. Of course, they're the best out there. Safe site and trusted sources for me. Be aware of the ad results. I wish there were better ways to contact the customer support/help/feedback team.
Google is a great web search engine. It's child safe as long as your search queries are suitable. If you use Google Chrome with Google, it'll also have an extra layer of security. Google tracks your usage but you can easily delete this data in your Google My Account dashboard.
