Thanks, Buddy!

Yes, I have cross-checked with my analytics and I can see the clear difference in a drop in traffic. When I say organic traffic I mean we are not getting a visit from google/organic which was present earlier. Thanks for your valuable feedback and help. I would love to keep in touch with you.
