Hi, I understand the recent algorithm that affected the YMYL sites. I have seven years of experience in the Digital Marketing industry and I specialize in SEO and content. All throughout my career I've worked with agencies, working on multiple clients at a time. I had a client with the same issue, the client had a website selling dietary supplements in Australia and New Zealand. I was able to troubleshoot their issues and restore their ranks. I think I can do the same for you. Depending upon your sites, a through analysis should not take more than 10 days (for both sites). After a site check I'll start work on restoring the rank which will include both onsite (internal links, broken links/redirects, content, etc.) and offsite (mainly backlinks).
I have mentioned 3 milestones, for you to gain any benefit out of this, I'll have to do the first one. However, if you don't require me to do any of the remaining two, you don't need to pay me for that amount.
