Ever wondered why some web pages seem to effortlessly climb search engine rankings while others languish in obscurity? The secret often lies in what we call page authority. What is page authority in SEO?

Page authority refers to the measure of a specific webpage’s potential to rank well in search engine results. Developed by Moz, page authority is a numerical score ranging from 1 to 100. Essentially, the higher the page authority, the greater the chance a page has to claim one of those coveted top spots.

Think of page authority as the digital reputation of a website. Just as in the real world, where reputable individuals or businesses gain trust and influence over time, pages with higher authority tend to garner more visibility and credibility in the virtual world of search engines.

So, why does page authority matter? Well, in the fiercely competitive arena of online visibility, having a higher page authority can mean the difference between being buried on page three of search results and basking in the limelight of page one. Ultimately, understanding and optimizing page authority is a crucial aspect of any comprehensive SEO strategy, helping websites attract more organic traffic and achieve their desired online goals.

Read on to find out how to master this metric and turn the tide for your website in search engine rankings.

What is Page Authority in SEO?

In SEO, page authority refers to the importance or weight given to a page relative to a given search query.

Modern search engines such as Google use many factors (or signals) when evaluating the authority of a webpage.

Page Authority is one of those factors. It’s a comparative metric that allows you to see how your pages stack up against the competition in terms of their ability to rank.

Your website’s page authority score is calculated based on various factors such as the quality and quantity of inbound links, the relevance and authority of linking domains, the quality and relevance of the webpage’s content, and the overall trustworthiness of your website.

A higher Page Authority score indicates a greater potential for a webpage to rank well in search engine results.

Page Authority vs. Domain Authority

While they are related, Page Authority and Domain Authority are not the same.

Page Authority measures the likelihood of an individual webpage ranking well in search engine results, focusing specifically on the strength of that particular page.

On the other hand, Domain Authority assesses the overall strength and authority of an entire domain or website, taking into account factors such as the quality and quantity of inbound links, the overall trustworthiness of the domain, and other SEO-related metrics.

In essence, Page Authority is specific to individual pages while Domain Authority provides a broader view of the overall strength of a website’s domain. Both metrics are developed by Moz and are used to gauge the SEO performance and potential of webpages and websites, respectively.

How Moz Calculates Page Authority

Using a specific algorithm, a Page Authority score is generated using a 100-point system. Any pages that achieve a 90% or higher are deemed A+ level in terms of PA.

Moz’s algorithm takes into account dozens of factors, including the number and quality of backlinks pointing to the page, the page’s content, and the overall authority of the website it’s on.

What is a Good Page Authority Score?

Generally speaking, a PA score of 50 or above is considered “good,” while a score of 60 or above is considered “excellent.”

However, it’s important to remember that PA is a comparative metric, so what constitutes a “good” score will vary depending on your niche and competition.

How to Check Your PA Score

There are a few different tools you can use to check your Page Authority scores, but one of the easiest is MozBar, a free browser extension from Moz.

Simply install the MozBar, then navigate to the page you want to check. The MozBar will display the page’s PA score right in your browser, along with other key SEO metrics like Domain Authority and the number of linking root domains.

You can also use Moz’s Link Explorer tool to check Page Authority scores in bulk and compare your scores to your competitors.

Keeping a close eye on your PA scores and taking active steps to pump them up can help elevate your pages in search engine results, making it easier for more organic visitors to find their way to your site.

How to Improve Your Page’s Authority Score

So now you know what Page Authority is and how it’s calculated. But how do you actually go about improving your PA scores?

Create High-Quality Content

When your potential customers search for information online, what are they looking for? They want content to be engaging, even entertaining, but there’s another ingredient that’s just as essential: authority.

Focus on creating content that showcases your expertise and provides real value to your readers. Don’t just churn out short, thin posts for the sake of having more pages. Include data and research to back up your points, and provide a unique perspective or insight that readers can’t find elsewhere.

The more authoritative and valuable your content is, the more likely it is to earn natural backlinks and social shares, which can help boost your PA score over time.

Optimize On-Page SEO

Optimizing on-page SEO elements in your webpage can also help improve your PA score.

Incorporate relevant keywords naturally into your content, title tags, meta descriptions, headings, and URLs.

Use descriptive and keyword-rich alt text for images, and ensure fast page loading times.

Take a close look at your backlink profiles using a tool like Moz’s Link Explorer. Are most of your links coming from low-quality, spammy sites? Or do you have a healthy mix of links from authoritative, relevant websites in your niche?

Acquire high-quality backlinks from authoritative and relevant websites within your industry or niche. Focus on building natural and organic backlinks through strategies such as guest blogging, influencer outreach, and content promotion.

Internal link building helps establish a logical hierarchy within your website and distribute authority across your web pages.

Link relevant pages together using descriptive anchor text to help search engines understand the structure and context of your content.

Improve User Experience

Enhance the user experience of your webpage by ensuring intuitive navigation, mobile responsiveness, and readability.

Provide clear calls-to-action (CTAs) and make it easy for users to find the information they’re looking for.

Increase Social Engagement

Promote your content across social media platforms to increase visibility, engagement, and social sharing.

Encourage likes, shares, and comments to amplify your content’s reach and attract more traffic to your webpage.

By implementing these strategies consistently and diligently, you can improve your page’s authority score over time and enhance its visibility and rankings in search engine results. Remember that building authority is a gradual process that requires patience, persistence, and ongoing effort.

How do I increase page authority in SEO?

Invest in building a strong backlink profile by earning links from authoritative and relevant websites in your industry.

What does authority mean in SEO?

In SEO, authority refers to the perceived trustworthiness and credibility of a webpage or website in the eyes of search engines. Pages with higher authority are more likely to rank well in search engine results because they are deemed reliable sources of information on a particular topic. Authority is often measured through metrics like Page Authority (PA) and Domain Authority (DA), which consider factors such as backlinks, content quality, and overall website trustworthiness.

What is the difference between domain authority and page authority?

Domain Authority (DA) measures the overall strength and authority of an entire domain or website while Page Authority (PA) assesses the likelihood of an individual webpage ranking well in search engine results. While DA provides a broader view of a website’s authority, PA offers insights into the authority of specific pages within that domain.

What is a good page authority?

A “good” Page Authority (PA) score typically ranges above 50. However, the significance of PA can vary depending on the competitiveness of keywords and industry. It’s important to consider PA in comparison to competitors and industry standards rather than in isolation.
