Link Building Secrets Revealed by Melanie Nathan and 10 of Today’s Best Link Builders.
It’s a well-known fact that Google considers government sites extremely trustworthy sources because they have strict quality policies and they won’t just link to anyone. This is why, when it comes to high-quality backlinks for your site, a link from a .gov is like the Holy Grail. Unfortunately it’s also why .gov links are pretty much unattainable for most websites.
Luckily though, you can acquire at least one .gov backlink by participating and offering your expertise to help other business owners at community.sba.gov. If you enjoy helping and have the extra time, other .gov communities exist, too. Experiment with Google operators, such as [allinurl: .gov “your niche”] to find even more holy grail opportunities.
