Google is the world's most popular search engine, handling billions of daily searches. But have you ever thought about how Google works? What factors influence which websites appear at the top of their search results?
In this article, we'll look at Google's inner workings and the role of a Google Ranking Engineer.
The History of Google
Before we get into Google's inner workings, let's look at its background. Google was founded in 1998 by Larry Page and Sergey Brin when both graduate students at Stanford. The team worked to improve upon existing search engines by creating one that returned more relevant results.
Google's early days were marked by a focus on improving the relevance of search results. Google's algorithm, the set of rules and calculations that determine the order of search results, was constantly modified to deliver better search results to users.
Google developed a new function called PageRank in the early 2000s, which evaluated linkages between websites to assess the value and relevancy of each page. This significant advance in search technology contributed to Google's current dominance.
Google's Operation
Google crawls and indexes billions of online pages and then uses a complicated algorithm to estimate the relevance and value of each page. Let's go over each of these processes in further detail.
Crawling
Crawling is the initial phase in Google's process. This is how Google's web crawlers, often known as spiders or bots, visit billions of web pages and collect information about them.
A web crawler examines the HTML code of a page and follows any links on the page to other pages on the internet when it visits it. This approach is repeated until the crawler has visited every page it can discover.
Indexing
When the crawling is finished, Google's algorithm indexes the material on each page. This means that the algorithm examines the page's content, graphics, and other aspects to identify what it is about.
While indexing a page, Google considers a variety of variables, including the page's loading speed, structure, and content quality. A combination of these variables determines each page's relevance and importance.
Ranking
Google's algorithm analyses hundreds of parameters to determine a page's ranking in search results once it has been crawled and indexed. Among these elements are:
Relevance: The algorithm considers how closely the page's content fits the user's search query. Quality: Google assesses the page's content quality based on accuracy, credibility, and originality.
Google analyses the website's authority based on characteristics such as the number and quality of links leading to it. User experience: Google considers how simple it is for people to navigate the site and find the required information.
The Tale of a Google Ranking Engineer
Let's take a closer look at the role of a Google Ranking Engineer now that we have a fundamental understanding of how Google operates. These people are in charge of creating and enhancing Google's ranking algorithm.
Pedro Dias, a former Google Ranking Engineer, has written about his experience working at Google on his blog. Dias worked on improving search results for languages other than English, such as Portuguese and Spanish.
Dias notes that his role entailed examining search results in these languages for specific searches and identifying opportunities for improvement. He would then collaborate with engineers to create and test algorithm changes.
Google's Algorithm Changes are Critical
Google's algorithm is continually changing, with periodic modifications to improve the relevance and quality of search results. Some improvements are tiny, whilst others are big and can significantly impact website rankings.
The release of Google's RankBrain algorithm was one of the most significant improvements in recent years. RankBrain uses machine learning to better comprehend user intent behind search searches and offer more relevant results.
This upgrade significantly influenced SEO since it shifted from traditional keyword optimization to providing high-quality, user-focused content.
Backlinks' Importance in Google's Algorithm
Backlinks, also known as inbound links, point to your website from other websites. Backlinks are an essential feature in Google's algorithm since they indicate to Google that your material is valuable and relevant to other websites.
Backlinks, however, are not all made equal. Google considers the quality and relevance of the websites that link to yours and the anchor text used in the link. Backlinks from low-quality websites or those that use manipulative approaches can harm your website's rankings.
Google's Algorithm's Future
As technology advances, Google's algorithm may evolve as well. Artificial intelligence (AI) and machine learning are two areas that are anticipated to experience tremendous advancement.
Google's RankBrain system already uses machine learning, and AI might be used to refine search results further and improve user experience. AI may, for example, be used to understand and interpret voice search queries, which are getting more common.
Takeaway
The Google algorithm is a complicated and ever-changing mechanism determining which websites appear at the top of search results. While the algorithm's exact mechanics are closely held secrets, it's evident that characteristics like relevancy, quality, and authority are essential considerations.
Understanding how Google works and being up to date on algorithm modifications is critical for businesses and website owners to maintain excellent search engine rankings. By providing high-quality, user-focused content and building authoritative backlinks, you may boost your chances of appearing at the top of Google's search results and bringing more visitors to your website.
