Open Site Explorer by Moz
In 2004, Rand Fishkin and Gillian Muessig created SEOmoz which later came to be known as Moz.
The company tools were a one-stop solution for all search engine optimization issues faced by, both, beginners and professionals.
Open Site Explorer is such a tool, helping the user in scanning their database for backlinks and their strengths. This tool is vital, as a broken link could affect website ranking.
Some of its features are:
- Adding new data on a daily basis to keep searches up-to-date
- New and improved authority algorithm
- Guidance for newcomers of Link Building
Open Site Explorer is soon to be discontinued. However, a new and improved tool called Link Explorer is up for launch by Moz.
