Hi friends i am working on a site and after 2 months i got very nice results but in a day My mostly keywords loose their ranking ,down up to 100 rank , i am very sad because i work hard for my keywords , is keywords come again on rankings or not?
Rankings are going to go up and down. Continue to add quality content and continue getting quality back links to stay ahead. Once rankings are achieved, you need to work hard to maintain these rankings. It's not a set it and forget it job.
It could be google dance or sand box. Also there are some strangeness in google last few days. My site is losing positions right now too. I think there are some updates in google.
