Several studies and user experiences suggest that the quality of Google's search results has declined over time. A year-long study conducted by German researchers from Leipzig University, Bauhaus-University Weimar, and the Center for Scalable Data Analytics and Artificial Intelligence found a decline in the quality of search results, primarily due to SEO spam43. The study examined the search results for 7,392 product review queries on Google, Bing, and DuckDuckGo over a year. They found that SEO spam sites, which are web pages optimized for a search engine’s algorithm, were high-ranking among the results4. The researchers referred to the situation as a "constant battle" and a "cat-and-mouse game" that search engines seem to lose. They observed repeated patterns of review spam entering and leaving the results as search engines tried to combat it. Despite some improvement in Google's results during the course of the study, spam-centered content was still easy to find across all three search engines43. The problem seems to stem from search engine optimization (SEO), i.e., content created and tailored towards ranking on search engines, rather than focusing on useful quality information. This can take the form of pages crammed full of keywords, or else holding back key information until far down an article in order to increase read time3. In addition to the issue of SEO spam, Google's search quality has been criticized for other reasons. For instance, there have been updates to Google's search algorithm that deprioritize reference websites like dictionaries, lyric websites, and wikis while promoting video content. There have also been efforts to reduce the rankings of "misinformation" or "biased" content, which some users feel has led to a deterioration in search results2. Marissa Mayer, the former CEO of Yahoo and one-time leader of Google's search team, suggested that the declining quality of search results might be more a reflection of the declining quality of the web itself, rather than a specific issue with Google's search engine5. However, the consensus among many users and researchers seems to be that the quality of Google's search results has indeed gotten worse over time12345.
