I was telling about the sites which give new information and updates about search engine optimization. Semrush is a site for checking SEO metrics of a site. Like Domain Authority, Back Link profile, Page Authority, keywords etc. If you only have one site to check then you can get most of this info from them too for free. But if you want to do a bulk check or complete metrics then you need a paid package which is expensive. But you can get all these information from several different sites for free. Just need bit more time since you have to do it in several different places.
