It’s a great idea to monitor your website/blog comments for questions that may be answered by content you’ve already written. One, look for sites like Quora, Reddit, and Ask the Public that feature user-submitted questions that are relevant to your topic. To do this, (2) produce some content that addresses these issues head-on. Third, have it live on your site and provide links to the people who asked the questions. To avoid looking spammy, put a paragraph of text before your link.
