Enter up to 20 Links (Each Links must be on separate line)
Here is one of the most frustrating things that can happen to you in SEO: You spend three entire days researching and writing the absolute best blog post on the internet about a specific topic. It has beautiful images, a perfect layout, and brilliant formatting. You hit publish and wait.
A week later, you check Google. You are stuck on page four. The guy sitting at the #1 spot? His article is only 400 words long, has no images, and is terribly written. Why is Google rewarding a terrible article while punishing your masterpiece?
The answer almost always comes down to one single metric: Page Authority.
Google does not rank websites based entirely on who has the prettiest prose. They rank websites based on trust. If a hundred different websites are linking to that competitor's terrible article, Google's algorithm assumes, "Well, a hundred people voted for this article with a backlink, so it must be the most trusted source."
You cannot win the SEO game blindly. Before you even sit down to write an article, you need to know exactly how much "trust" your competitors have so you know if you can actually beat them. That is exactly why we built the RankZoa Bulk Page Authority Checker. It instantly pulls back the curtain on any URL on the internet, showing you exactly how much raw ranking power it holds.
Let's clear up some technical confusion. "Page Authority" (PA) is a specific metric originally developed by the SEO software company Moz. It scores a specific web page on a 100-point, logarithmic scale. The higher the number, the greater the likelihood that the specific page will rank high in Google search results.
A score of 1 means the page has absolutely zero trust and zero ranking power (like a brand new blog post published five seconds ago). A score of 99 means the page holds the raw power of a digital god (like the homepage of Wikipedia or Google itself).
Your PA score is calculated by analyzing dozens of factors, but the absolute biggest factor is your link profile. How many external websites are linking directly to that specific URL? Are those websites high-quality, trusted sites, or are they spammy, toxic blogs?
This is where 90% of beginners get incredibly confused. You have probably heard of Domain Authority (DA) and Page Authority (PA). They sound similar, but they measure entirely different things.
Why does this matter? Because a massive website with a DA of 90 can publish a brand new blog post today. Because that specific blog post is brand new and has zero backlinks pointing to it yet, its PA might only be 15. If your small blog has a highly linked, highly shared article with a PA of 45, you can actually outrank the massive DA 90 website on that specific topic!
Our tool isn't just for checking your own score to boost your ego. It is a tactical weapon for competitor research. Because our tool allows you to check URLs in bulk, here is the exact strategy you should use:
What is considered a "Good" Page Authority score?
Page Authority is completely relative; there is no universal "good" score. A PA of 30 is terrible if you are trying to rank for the keyword "Credit Cards" (where competitors have a PA of 85+). However, a PA of 30 is incredibly strong if you are trying to rank for a niche keyword like "Best vegan dog food in Austin Texas." The only thing that makes your PA "good" is if it is higher than the PA of the specific competitors you are trying to outrank.
Does Google actually use Moz's Page Authority to rank websites?
No. Google does not use any third-party metrics like Moz's PA or Ahrefs' DR. Google uses its own heavily guarded, secret algorithm (historically known as PageRank) to evaluate backlinks and trust. However, because Google keeps their true scores hidden from the public, Page Authority is widely considered by the SEO industry to be the most accurate public estimation of how Google views a page's strength.
How can I increase the Page Authority of my article?
The fastest and most effective way to increase your PA is to acquire "dofollow" backlinks from other high-authority websites pointing directly to that specific URL. You can achieve this by guest posting, running digital PR campaigns, or simply creating "link-bait" content (like original research, data studies, or amazing infographics) that other bloggers naturally want to link to as a source.
Why did my Page Authority suddenly drop?
Because PA is a logarithmic scale comparing your page to every other page on the internet, your score can fluctuate even if you did nothing wrong. If Moz updates their index and discovers that a massive website (like Facebook or Wikipedia) acquired a million new links, the "ceiling" of the 100-point scale rises. This can mathematically push everyone else's score down slightly. Don't panic over a 2-point drop; focus on the long-term trend.
