Search Algorithms

Search engines have complex search algorithms which are used to ensure they are able to display the most relevant and useful results to their users. While algorithm changes are common and won’t usually affect a site’s ranking, search engines such as Google will occasionally introduce a major update which may impact search results. Our Hangout Notes cover insights from Google around these algorithms with best practice advice.

Expect Ranking Fluctuations For New Content

Google Doesn’t Sandbox New Sites

Google doesn’t have a sandbox acting as a filter on new sites. There are a number of algorithms that might look similar to a sandbox, but these understand how the website fits in with others trying to rank for those queries. In some cases this might result in pages ranking higher or lower for a time, while Google figures out where it should rank.
