Okay kiddo, imagine you're playing with your favorite puzzle. The puzzle has 10 pieces that all fit together perfectly. Now imagine that you have lots of other toys that match up with those puzzle pieces too. They are all like your puzzle pieces' friends!
Now, imagine that you're playing with your puzzle and you have your cousin over. You really want your cousin to see your puzzle, but they don't know where to find it. So you take the first piece of your puzzle and put it in the toy box your cousin is playing with. Your cousin picks up that puzzle piece and thinks, "Wow, this is really cool! I wonder where the rest of the pieces are?"
That's kind of how backlinks work, kiddo. A backlink is like a piece of your puzzle. It's a link on someone else's website that leads back to your website. When someone clicks on that link, they come to your website and they might think it's really cool. They might even want to explore your whole website and become a fan of it!
Just like how you put the puzzle piece in the toy box for your cousin to find it, other websites put your backlinks on their website for people to find your website. The more backlinks you have, the more chances there are for people to find your website and become fans of it. And just like how your puzzle pieces' friends all match up with each other, the more high-quality and relevant websites that backlink to your website, the more valuable those backlinks are.
So long story short, backlinks are like puzzle pieces that connect different websites together and the more of them you have, the more people will find your website and become fans of it.
