Kiddle is a visual search engine for kids, powered by Google. It offers safe search i.e. the results satisfy family friendly requirements with explicit or deceptive content filtered out. The results have big thumbnails with a larger font, making it easier for kids to choose the link they need. And the results are displayed in a manner that makes it easier for kids.
Typically results 1-3 are safe sites and pages written specifically for kids, handpicked and checked by Kiddle editors.
Results 4-7 are safe, trusted sites that are not written specifically for kids, but have content written in a simple way, easy for kids to understand. Again handpicked and checked by Kiddle editors.
And result 8 onwards are safe, famous sites that are written for adults, providing expert content, but are harder for kids to understand. This is filtered by Google safe search.
A Visual search engine can work in two ways – (1) the search is designed to find an image based on keywords, a picture, or a web link to a picture or (2) like Kiddle, the search engine shows results with a visual display image.
