One-way Links: What are they and how can they help your ranking?
One-way links are links to your site from other sites that do not receive a backlink from your site.
This tells search engines, like Google, Yahoo, and Bing that your website is so important and interesting that other sites want to tell people about it without anything in return.
One-way links are wonderful things to have because they increase your link popularity – the number of pages linking to your site. Search engines such as Google place huge importance on link popularity when ranking your site.
