Define Moz, Ahrefs, SEMRush and Screaming Frog

Moz: It helps businesses to analyse and get insights about their websites and their competitors.

Ahrefs: Ahrefs is the best tool if you want to check your or your competitor’s backlinks.

SEMRush: SEMRush helps you check the health of your backlink, the position of your keywords, and errors in your website.

Screaming Frog: It crawls your entire website and lists out all key elements like internal links, external links, titles, descriptions, HTTP status code, and more.
