I am a huge fan of the TopicMojo ! It has helped me identify profitable niches for my website and has helped me to optimize my content richly around specific topics. I use this service to uncover new topics for articles, profitable keywords to target and more. It's a very helpful service for any blogger looking to expand their audience and profit from better content. Just now they released an update that shows posts from Tiktok, Medium, Etsy, Tumblr and Tech Crunch. Get it now before price increase
