I am planning to create site directory, but I learned that Google consider site directories as low quality. They emphasized that without any editorial effort to maintain a web directory and without continues effort to update them will bound to fail. I clearly understand the Google algo updates. I need your analysis if creating a more modern way for site directory can still be possible now today.
What I'm planning to do:
- Review sites that are not spammy before adding to directory
- Put a "dofollow" link without anchor text
- Make sure that all contents are unique and meaningful to visitors
- No keyword stuffing
- No misleading content
If I do these does Google consider my site as a high quality one even though I pass PageRank?
I am planning to place it in the subdomain, does it affect the rank on my main domain or just on the subdomain itself?
