Why link building is required in SEO?
Thanks in Advance.
As far as I know it's a free choice. Not requiered, but you can use it.
Well, here is my important opinion:
1. If you make perfect, unique content you don't need link building.
2. If you have perfect, unique content plus good on-page SEO, you don't need link building at all.
Some of our ranking success proved it.
3. For SURE link building MATTERS (still).
