What Is a Trust Signal?
Let’s say you are interested in the topic of a book by an author you aren’t familiar with.
"Trust signals," broadly defined, are the evidence points that inspire confidence in your brand online. The term goes back to the early days of Internet commerce and has become even more relevant today.
The first trust signals, described in an article published in the March 2000 edition of the Journal of Computer-Mediated Communication, were "trust badges" or "trust seals" from organizations such as the Better Business Bureau and TRUSTe on e-commerce websites. Twenty years ago, many consumers were skeptical of providing their credit card information and other personal details to a website -- any website. Trust signals helped visitors to overcome their fears and build e-commerce trust.
Today, not just e-commerce but all commerce is largely conducted online, thanks to the ascendancy of inbound marketing. The trust signal remains vitally important to attracting and converting website visitors who are not yet familiar with your brand.
Trust signals are important to Google as well. Virtually every trust signal is a ranking factor in determining your site's search position. That's why SEO professionals and software use terms like "Trust Flow," "TrustRank" and "MozTrust" to describe what they do. They know that Google is trying to determine how trustworthy your site is in the same way that potential customers are.
In current digital marketing parlance, a trust signal can fall into three major categories:
Following is a comprehensive list of trust signals. Keep in mind that for trust signals like star ratings, newsletter subscribers and products sold, the signals only work if your numbers are impressive. If your reviews are mediocre or your e-commerce sales are poor, be sure to improve those numbers before using them as trust signals.
