Now that you have figured out the cause of the penalty, now is the time for recovery. And here are a few things you can try-
• Don’t panic. Even massive websites suffer from penalties.
• Disavow troublesome links. Ask Google not to count troublesome links that are harming your website
• Get some links removed. While disavow is good, it’s not perfect. Try to manually remove the links.
• Request reconsideration if your penalty was manual.
• Wait it out. Sometimes it takes Google a while to act on your changes and disavow requests, and then it could take a while for it to re-crawl your site.
In a few cases, it’s better to abandon a site rather than fight a Google penalty: if your domain has been tarnished, there’s little you can do. But most penalties can be fixed with a little effort, some hard work and an ethical approach to rebuilding your site.
