We may not know all the ranking factors that Google uses in its algorithm, but we know that links are at the top. But not all links are created equal. This is where link equity comes in .
Link equity, which some like to call " link juice ," refers to the value a site conveys when it links to yours. Different sites have different values because of this thing called domain authority.
Domain authority gives you an idea of how trustworthy your site is to search engines. It is a numerical value from 1 to 100, so the higher the number, the more trustworthy your site is. While it is not necessarily australia whatsapp number database used by search engines to determine your site's position in the SERPs, domain authority can help you understand which sites will pass on the most link equity from backlinks.
You can measure your domain authority with Moz’s tools, or your domain rating with Ahrefs’ tools.
I'll give you an example of how these metrics work. You've probably heard of big news sites like the New York Times , the Wall Street Journal, and the Associated Press . These sites have spent years building consumer trust and earning a lot of links to their articles.
I think it’s fair to say that they are industry leaders. If the New York Times links to your site, it will convey much more link equity than a link from a personal blog because it has a higher domain authority . That’s not to say that links from smaller sites aren’t good, if only because your audience may frequent smaller, more niche blogs.
