WebBreadth-first search (BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level.

WebBFS can be used to create web page indexes in web crawlers. It is one of the primary algorithms for indexing web pages. It begins by traversing the source page and then … WebBFS Algorithm is known as (Breath-First Search) for traversing a graph. This algorithm helps to reach the specific node or through the vertex route of the data structure. The BFS algorithm works horizontally for the particular layer and moves to the next layer afterward.
