What is TrustRank?
TrustRank is an algorithm designed to differentiate between reputable (non-spam) and spam sites, helping search engines rank pages more effectively. The primary goal of TrustRank is to assess the trustworthiness of web pages based on their likelihood of being reputable.
Origin and Concept
TrustRank was first introduced in 2004 by Zoltan Gyongyi and Hector Garcia-Molina from Stanford University, along with Jan Pedersen from Yahoo!. They proposed this concept in their paper "Combating Web Spam with TrustRank," aiming to address the limitations of PageRank, which could be manipulated and was insufficient for measuring a website's trustworthiness.
How TrustRank Works
The main idea behind TrustRank is that reputable (good) pages seldom link to bad (spam) ones. Here’s how it works:
- Seed Sites: The process starts with a set of human-reviewed, reputable, and trusted "seed" sites.
- Crawling Links: The algorithm then crawls the outgoing links from these seed sites.
- Link Hops: The fewer link "hops" it takes to reach a given page from these seed websites, the higher its TrustRank.
Does Google Use TrustRank?
Not Exactly...
Although many mentions of "Google TrustRank" can be found on the web, it's incorrect to say that Google uses the exact TrustRank algorithm from the original research. Yahoo! patented this concept under the name "Link Based Spam Detection," so Google couldn't use it directly.
Google did use the term "TrustRank" and even trademarked it in 2006, but it referred to an anti-phishing filter, not the same concept that Yahoo! developed.
Google's Approach to Trust
Google has its own mechanisms to determine the trustworthiness of web pages. While not using Yahoo!'s TrustRank directly, Google employs several trust-based algorithms and factors. One such patent is titled "Search Result Ranking Based on Trust," which adjusts information retrieval scores based on trust factors.
Factors Contributing to Trustworthiness
SEOs believe that the following factors may contribute to a website's trustworthiness in Google's eyes:
- PageRank: Although PageRank alone isn't sufficient, it plays a role in determining trust.
- Website Age: Older, established websites are often deemed more trustworthy.
- Age of Inbound Links: Older backlinks can signal long-term trust and credibility.
- Quality of Backlinks: High-quality backlinks from reputable sites enhance trust.
- Authority of Authors: Content written by recognized experts can boost trust.
- General Content Quality: High-quality, well-researched, and relevant content is crucial.
Importance of TrustRank in SEO
Understanding and improving the factors that contribute to TrustRank is vital for SEO. By focusing on creating high-quality content, earning reputable backlinks, and maintaining a well-structured and user-friendly website, you can enhance your site's trustworthiness, which can positively impact its search engine rankings.
