In order to stay ahead and minimize risk, being proactive is far better than being reactive.
In general, focus on the following;
- Providing high quality content. Provide content that is unique and relevant to the user. Do not overstuff content with target keywords.
- Optimizing your site for the user. Ensure that users have a positive experience and get the information they need (searched for). Factor in page speed, load times and design. Follow best practices for mobile search.
- Earning links rather than buying links. Focus on high-quality, credible sources, and only link to relevant content.
