I recently had a friend message me stating that he was getting notices from other bloggers that his site was marked as spam or malicious. Although Google Webmaster Tools stated his site was clean, another site said something entirely different. This is directly affecting not only potential traffic to his site but also his relationship with other bloggers, and he was losing his online reputation and money. This is definitely not something you want to happen to you! Check out these free online tools to see if your site has been flagged as spam or malicious and how to fix them.
