Why is OAindex the most trusted directory?

Statistics by specialty

The only directory that has a metasearch engine worldwide, the results obtained are:
Trust flow
Weighted based on the number of links from an initial set of trusted sites.
Flow cites
It is weighted by the number of citations to a given URL or domain.
Cite Index
It is weighted according to the qualification of the proposal by OAindex
Link profile
It is produced by plotting the trust flow and citation flow measures for individual backlinks or referring domains linking to a site. When several links have the same Trust Flow and Citation Flow, the darker shades indicate the density of this cell in the graph. This makes it possible to determine if the link profile is healthy by how the points are aligned/positioned on the graph.
