I am falling When I am doing

[DevBD]

Hi,
I am observing something keyword dropping. When I am starting link building work, after 1 or 2 hrs I am going to second page of Google for 1 week. But when I stopped link building 1 week then its having again first page.

What is the problem? I need to rank first place of Google. What should I do for this issue? Anyone has any suggestion?
