Seoquake: Semrush was not left behind and also launched its extension: SEOquake. This extension is like MozBar, but with more detail. It shows different metrics and expands them in a diagnostic panel.
Likewise, it also shows you SEO On Page and SEO Off Page factors. In the SERPs, it will show you metrics about the keyword you are looking for, its difficulty, and competition. Pretty cool, isn’t it?
SEOquake is much more powerful than most SEO extensions for Chrome. If you still don’t know which one to use, we recommend you start here.
