Sudden drops in organic traffic can be alarming and are often due to search engine updates, outdated content, or new competitors targeting your keywords. Start by checking if there was a recent Google algorithm update that might have affected your rankings. Tools like Google Analytics and Search Console can reveal whether specific pages or keywords were impacted, helping you identify the root cause. Outdated or thin content can also lose rankings over time, so consider updating your high-traffic posts with fresh information, optimized keywords, and more depth to match current search intent. Competitor analysis is equally important; if new or improved sites are ranking for your target keywords, see what they're doing well and adapt accordingly. Boosting internal linking and adding fresh content can also help regain visibility. Addressing these factors can gradually restore your traffic levels.
