Organic traffic refers strictly to the free, search engine-generated traffic. It’s important to emphasize that it’s free because the top few results on search engine pages are paid advertisements, which do not count towards organic traffic.
Google organic search results placement
After the paid ads, the organic search results follow.
When you search for something on Google, the first few results on the list are paid ads, which you can only appear in by paying for placement. After the paid ads come the organic (unpaid) results, which anyone can appear in through search engine optimization (SEO).
SEO involves optimizing your website so that it ranks higher in the organic search results for specific keywords.
Good ranking is crucial because 90% of people only look at the first page of results, and 50% of them will click on the first result!
