Google's search engine continuously updates its algorithms to provide internet users with the most accurate and relevant information. These algorithmic updates directly impact SEO (Search Engine Optimization) strategies, as they determine how websites are evaluated and ranked in search results. Google's primary objective is to deliver high-quality, useful, and trustworthy information to users. Therefore, the company places significant emphasis on enhancing search result quality and providing precise answers. In its early years, Google relied on keyword-based indexing methods. At that time, website owners used techniques such as keyword stuffing to achieve higher rankings in search engines. However, since these methods negatively affected user experience, Google developed new algorithms to address these issues. Today, Google's search engine evaluates web pages based not only onkeyword frequency but also oncontent quality, userexperience, mobile-friendliness, link authority, and page loadingspeed [5]. The evolution of Google's algorithms has led to several significant updates aimed at improving search result quality. For instance, the Panda algorithm eliminated low-quality and duplicate content from search results. The Penguin algorithm targeted artificial link-building (black-hat SEO) practices. Hummingbird and RankBrain introduced semantic search technologies to better understand user intent. More recently, the BERT and Helpful Content Update algorithms have been designed topromote naturally written, valuable content (Figure 1). Figure1.GoogleAlgorithms. SEO strategies must adapt to these changes in Google algorithms. While technical aspects were previously the main focus, the current approach emphasizes creating high-quality content, aligning with user needs, and acquiring reliable backlinks as key components of SEO strategy. Due to the impact of algorithmic updates, website owners have been compelled to abandon spam techniques and develop valuable, user-centric materials[1]. This article provides a detailed analysis of the evolution of Google algorithms and their impact https://ijmri.de/index.php/jmsi volume 4,issue2,2025 524 onSEOstrategies. Specifically, it examines the majoralgorithmic updates implemented in recent years, their influence on search results, and how SEO specialists should adapt to these changes. Throughout the study, scientific approaches and practical strategies related to the impact of Google algorithms onwebsiteoptimization willbe explored. Methodology. In this study, the changes in Google algorithms and their impact on SEO strategies were thoroughly examined from both scientific and practical perspectives. The main objective of the research is to determine how Google's algorithmic updates affect website rankings, organic traffic volume, and SEO strategies. To achieve this, analyses were conducted based on scientific articles, SEOexperts' experiences, official data published on the Google blog, andreal websiteperformance results. Two main approaches were used in theresearch—theoretical analysis and practical analysis. Within the scope of the theoretical analysis, the historical development of Google algorithms, search result evaluation criteria, and ranking principles were studied.
