I'm new in the blog and I'm quite a beginner in SEO. I want to share and have some clear feedbacks about what is happening with my website.
In the last month we experienced two drops in Domain and Page Authority. Both times seem this happened because we sent a mail merge. The first time the server was shut down and the website was down for some hours. I also want to precise that the mails were newsletters but actually we didn't follow the best practices in order to avoid spam.
Do you think the drop is due to the mail merge practice?
I hope the situation is clear enough. I would like to have some comments, feedbacks and if possible suggested solutions.
