Anything less and you'll pay for poor quality domains, poor quality content, and poor services. Buying backlinks can give you an advantage over other business owners who are just waiting for natural link building to take place. While backlinks are naturally acquired over time as other sites link to your site, you can create them with some legitimate practices. The obvious reason to buy backlinks instead of building natural links is to save time and generate better opportunities.
Paid link building is the practice of websites that pay other websites for backlinks that point to their own domain. Think about what types of pages and keywords you want link creation to have an impact on, draw up a prioritized list and carefully research your competitors to see what they will need in terms of backlinks to compete and, ultimately, overcome them.
