Here are the components you should work upon to maximize your site’s TrustRank. These components are most of the factors that impact your site’s TrustRank.
The Number of Backlinks
The more authority sites that link to your domain, the more Google and other major search engines will think “Wow, this webmaster is famous. He’s well-known by so many other websites. He would be a trusted brand to have got this much connection and love.”
Quality of Backlinks
If you are having high-quality and strong links from quality and trusted websites coming to your domain, Google will see them as trusted external votes that are giving your site trust credits. But if such links are coming from low-quality, untrustworthy websites, Google will regard you as a bird of the same feather. Links coming from .edu sites, A-list blogs, .gov sites, and so on are usually regarded as trustworthy and authority sites.
TrustRank of Websites Linking to Your Domain
If you have sites linking to your blog from external sources, it’s a rule of the thumb to always check and find out if such links are coming from ridiculously low-quality sites as these can impact your TrustRank negatively.
Google PageRank of Sites Linking to Your Domain
This, of course, gives more preference to the high-quality sites over the low-trusted ones. If you’re getting links back to your domain from external domains, ensure you always check their Google PageRank since TrustRank is proportionally based on Google PageRank.
Consistency
Consistency is the key when it comes to impressing Google. Google loves consistent sites. Do not publish a great post today, and no post at all for the next 4-5 months. Don’t do this and expect that Google will assign good rankings to your website.
While publishing fresh posts frequently, also keep the old posts up to date and improve your Google PageRank with time.
