2.1: Introduction to Search Engine Algorithms

Search engine algorithms are complex systems used by search engines like Google, Bing, and Yahoo to deliver relevant search results to users.

Search engines use crawlers or spiders to scan the internet for websites and index them based on their content and relevance to specific keywords. When a user enters a search query, the search engine uses its algorithm to analyze the indexed websites and deliver the most relevant results.

Optimizing a website for search engines involves understanding how these algorithms work and implementing strategies to improve a website's visibility and ranking in SERPs. By optimizing a website for search engines, businesses and individuals can increase their online presence, attract more traffic, and generate more leads and sales.
