Linking Out
You must consistently link out to domains that are highly trusted by Google such as the .gov, A-list blogs, .edu sites and so many others out there. This strengthens your trust and places you in a good position in SERPs.
Domain Age
This doesn’t alone symbolize the present age of your domain name but its lifespan. This implies that Google places much more trust on domains that are registered for the next, say 3 years or more than those that were registered for just one year, as the former signifies to Google that it’s going to stay around for a longer time compared to those registered for a 12 months period only.
Registering a domain name for a period beyond one year is a great way of telling Google that you’re optimally committed to what you’ve started.
Controversial Topics
Gambling, pornography topics will impact your TrustRank negatively and will probably hold your site to ransom with search engines. Of course, you wouldn’t want to pollute your site with such topics.
Blockings
If a site gets blocked by so many users, it creates a bad impression that such a site is not trusted. Because Google detects how many users’ browsers are blocking your site, avoid getting blocked.
WHOIS Privacy
This is a way of displaying how trustworthy you are to the audience. In order to prevent spammers from accessing your site’s data and that of your users, leverage WHOIS privacy.
Brand Signals
Having got lots of mentions on authority and highly-trusted websites, Google will believe that you have quality content on your personal blog and will begin to trust your site while improving it in SERPs.
Length of Your Domain
If you’ve ever thought of using a very long domain name for your website, you’ll miss out on a significant ranking position in SERPs. Google officially disclosed that one of the best ways to create better user experience is by making your domain URL memorable and short.
