Summing Up

When looking for the best link-building agency, there are some important factors you should pay attention to, and these are:

• Transparency

• Quality

• Turnaround time

• Strategy and methods (strictly white-hat or not only)

• Reliability 

• Audits and reporting 

• Pricing 

A truly reliable agency should be open and transparent about its methods, which should be “white-hat” only and not rely on spammy platforms. Ideally, they should also be able to provide you with a portfolio or just samples of case studies of the work they have done previously. This will help you see the quality of their work, how niche and customized it is, and how well it matches your vision for your brand.

Pay attention to meaningful metrics, such as organic traffic growth and keyword ranking improvements; sometimes, 5 quality backlinks are better than 50 spammy ones. In link-building, like in many other industries, quality should be prioritized over quantity!
