Do sitelinks really mean authority? The short answer is no.
Do they mean well indexed and established? yes.
Sitelinks are certainly not a measure of if a website is authority but you only see them on well indexed older better established sites. So in a way they it can be one metric to look it.
Here are a list of paid website directories with sitelinks:
- Bam Directory
- Authority Directory
- Aviva Directory
- JoeAnt Directory
- Elib Directory
- Ally Directory
- Massive Links
