I am the owner of an ecommerce site in New Zealand. We manufacture a line of nutrition supplements and sell locally. We are one of the largest in NZ.
We are a YMYL site and have been very affected by the recent changes. We have dropped off google altogether and I have been unable to find any reasons why. (Previously we had been up to 2nd place and were first place for many product listings)!
I need an SEO who is familiar with very the recent changes for ongoing work to correct this and build back up.
