Search engine preferences do update from time to time, and usually this update is continuous. This is because search engine algorithms and ranking mechanisms are constantly optimized and improved to better meet the needs of users and improve the accuracy of search results.
Updates to search engines typically include the following:
General updates: Search engines regularly update their indexing databases and ranking algorithms to adapt to changes in content and changes in user behavior. This type of update is usually done on a regular basis, such as monthly or quarterly.
Major update: In addition to the regular updates, search engines may also make significant updates, such as overhauling the ranking algorithm or making significant adjustments to the evaluation criteria. These updates can have a big impact on rankings and therefore require close attention from administrators and SEO experts.
Human intervention: Algorithm updates for search engines may also be affected by human intervention, such as in some cases, search engines may make manual adjustments or restrictions on specific ** or specific keywords.
In either case, search engine preferences are updated to improve the accuracy of search results and user experience. Therefore, administrators and SEO experts need to pay close attention to the update dynamics of search engines and adjust their optimization strategies accordingly to improve rankings and traffic.
