This is when you popped up in a search
engine (Google, Yahoo, Bing, etc.) and someone came to your website that way. Having a high organic search percentage means people are finding you themselves through the web. This is excellent if you’re running a SEO (Search Engine Optimization) campaign and want to be found via search
engines. When this number gets low, you run the danger of becoming irrelevant to people searching, which can be detrimental if your website needs to be found on its own.
