Hi all,
We have a site named as https://goo.gl/QSs68r, on 18 August 2017; we had a problem regarding the server. The problem solved on 23rd August 2017. That time our website was in top rank but since this issue the website has moved to the 200 rank. It has been around 40 days and rank is still there from past many days. We are consistently taking a good links and doing the activities regularly.
