Imagine you have a lemonade stand. If you go out and shout to people walking by, inviting them to try your lemonade, and they decide to come over and buy some, that's like an organic lead. You didn't pay anything; you just used your voice and your presence. Now, if you pay your friend to stand at the corner of the street with a big sign that directs people to your lemonade stand, and people come because of that sign, that's like a paid lead. You spent some money to get their attention and bring them to your stand. The main difference is that organic leads come naturally from your efforts and presence, like word of mouth, search engine results, or people passing by. Paid leads come from spending money on advertising or promotions to directly bring people to your business.
