Search engines for kids work with so-called whitelists – this is where websites that are seen as being harmless for children are listed. Conversely, a blacklist contains the exact opposite. This is where content that should not be accessed by any means is listed. This leads to a dilemma of sorts: should the sites that you allow your child to see only consist of those that are on the whitelist, or should all websites be permissible, as long as they don’t feature on the blacklist? Given that the main idea behind child protection is to ensure safety and that the World Wide Web is developing so fast that it is impossible to maintain a comprehensive and authoritative blacklist, safe search engines for kids tend to base themselves on the whitelist.
Most normal search engines use their own webcrawlers. They scan the entire web and analyze the results. With the likes of safe search for kids, this is usually done manually. The people behind these search engine manually add websites to the whitelist and check whether they are still live and relevant. This editorial supervision means that the search engine functions more as a web catalog, similar to what would have been around in the early days of the internet. Thus, most search engines for kids function simultaneously as a portal. Alongside their actual search function, they also recommend particular webpages, as well as their own content in the form of games and courses about how to use a search engine correctly.
In order for a website to be entered into a whitelist, there are certain criteria that such search engines require them to meet. Alongside the type and structure of the content, things like data protection, advertising, and paid services all play a role when it comes to evaluation of these websites. Websites for children should be safe and secure insofar as they do not pass on any sensitive data or trick visitors into parting with their money. Ideally, there should be no advertising at all, and if there is, then it should be content that is appropriate for children and make it very clear that it’s an ad. But even search engines for kids don’t offer full and comprehensive protection for children. It’s always possible that links will lead young visitors to other content that is not as suitable for people in their age bracket. However, with the combination of child protection software and adult supervision, search engines for kids offer a great possibility to make the internet a very useful resource for young children.
