Ahrefs

Ahrefs Pte. Ltd. is a software company that develops online SEO tools and free educational materials for marketing professionals. Ahrefs is an all-in-one SEO toolset for growing search traffic and optimizing websites. To do that, Ahrefs crawls the web, stores tons of data and makes it accessible via a simple user interface. When Ahrefs launched its first tool, Site Explorer, it disrupted the stagnant field of backlink analysis and kickstarted a new round of competition among SEO tool providers. It quickly became one of the world’s best backlink analysis tools. Since then, Ahrefs has grown into a complete SEO suite by developing tools like Keywords Explorer for keyword research, Content Explorer for analyzing content, Rank Tracker for monitoring keyword rankings, and Site Audit for auditing and optimizing websites.
