Google Search
Every search takes place within Google’s list of indexed websites, which is created by search engine “spiders” (crawlers). These crawlers scan web links, which is why it is important for your website to have high-quality internal and external links—trusted sources help improve search rankings.
When learning about SEO, you will often encounter the term SERP (Search Engine Results Page). These are the pages displayed in response to a user’s search query. SERPs may include not only website links, but also images, shopping results, articles, a knowledge panel, related questions, or even tweets.
