Google Sandbox or simply "Google sandbox" is a term that specialists SEO sometimes use in the context of positioning newly created websites. This term refers to the theory that new websites are initially treated by Google with a certain limitation in terms of visibility in search results and positioning.
According to this theory, new websites have to go through a certain 'sandbox' period when, like children in a sandbox, they are 'watched' and observed by the older ones. During this time, their influence on search results is limited and they are not treated as competition to older, more popular sites. In practice, this means that a new site may experience low visibility in search results for a limited period of time after its creation.
However, it is worth noting that the existence of Google Sandbox has not been officially confirmed by Google. Some SEO specialists dispute this theory and believe that any limitations that new sites may experience are due to the natural process of indexing and assessing content quality by search engine algorithms.
