I need to know what type of encoding is involved in this url string:
http://www.newcarfax.com/chevy-vehicles/?bmv3y2fyzmf4lmnvbq=Nw==86aPMTU4YTo1OntzOjQ6InBhZ2UiO3M6MzM6Imh0dHAlM0ElMkYlMkZ3d3cubmV3Y2FyZmF4LmNvbSUyRiI7czo3OiJrZXl3b3JkIjtzOjE2OiJ0cnVjaytkZWFsZXJzK2luIjtzOjM6InNyYyI7czo2OiJ0cnVja3MiO3lSd1oeSM6NDoia3dyZCI7czoxNjoidHJ1Y2srZGVhbGVycytpbiI7czo1OiJzdWJpZCI7czoxNDoidHJ1Y2tzKy0rY2hldnkiO30=&kwrd={ifContent:{placement}}{ifSearch:{keyword}}
This was used for SEO purposes and I would like to do the same if possible. An application was used to create this and I'm not a programmer to figure out how it was created besides what what data I typed in it to create it.
PLease, help!
Thanks
