Can you update me on the effectiveness of Google buying links from .edu and .gov sites?
Some time ago it was helpful, but is it still relevant or no longer impactful for Google?

The importance of links has decreased in search engines. It is advised to be cautious when purchasing links as they can lead to filtering. Additionally, search engines evaluate the quality of the linking site, including the number of outgoing links.
A better approach is to focus on building a natural link profile for better results.
