have you ever heard of search engines? go search there and they'll give you paid and organic results so you'll see the difference.
When you are looking for a certain product or idea and you search Google for that topic then click one of the websites listed on the search result, stayed there to read or made a purchase then that’s what you called organic search. Paid result is basically that, paid. Either through PPC or any other means.
Organic - All the result are free here and its depend on the google algorithm factors. Paid- All the result are paid and depend the cost on per keywords while bidding.
Hi, Organic results are generated by SEO activity's, where as paid result are generated by paid Ad campaigns like PPC or CPC
What exactly is your idea to ask this question? Don't you really know what's the difference? Did you use Google? But I assume you researched both the keywords as you named them right (paid and organic!)
