GOOD TO KNOW
Common mistakes, an example and the limits.
Common mistakes
- Pitching directories and link farms just because competitors are there.
- Mixing exports from different tools without normalising them (this tool normalises domains).
A worked example
Three competitors share 26 referring domains that do not link to you, including two Kenyan tech blogs and a university careers page.
Limitations
- Your export is read in your browser and never uploaded.
- Only as complete as the exports you paste.
