Most of the webmasters have heard about Pyramid of backlinks which makes your website appear at good position on Search Engine.Although only few people know how exactly it work.
I would start the explanation of pyramid links and how it works.
We know that when we have one do follow backlink of the website and when google goes through that website then while reading the content of that website , Google comes across your Link . And so Google also visits your link the same as a human behaviour.So here lies the secret.
Now when you have one backlink at any website (say website1) and then again if you have backlink to website1 at some other place then its very often is the case that Google comes to your link and goes through your website.so this is how the pyramid of backlinks work and improves your SEO and thus your internet traffic.
