Why should you care about domain authority?
By now, you realize just how important it is for your site to be visible in search engines.
Search engines like Google are the primary mode of discovery for billions of users, so if you can get your site at or near the top rankings for relevant keyword phrases, you can secure an ever-growing stream of new traffic to your website.
But many online business owners neglect a fundamental element of search engine optimization (SEO) strategy: domain authority.
Learning how to increase domain authority and using a good domain authority checker can dramatically improve your overall SEO results.
In this guide, you’ll learn the intricacies of how domain authority is calculated, why domain authority matters, and of course, the strategies you need to be successful in improving it.
What is domain authority?
Let’s start with a basic outline of what domain authority is and how it functions.
Domain authority is a cumulative score of trustworthiness for a given web domain.
When search engines formulate search engine results pages (SERPs) they usually look for two things: relevance, or how appropriate the content is for the given query, and trustworthiness, or how valuable and reputable the content is.
Domain authority is useful for gauging how reliable a website’s content is; the higher the domain authority for a site, the more likely its content will be to rank highly in SERPs.
Google doesn’t explicitly publish these scores, nor does it document how these scores are calculated. Instead, SEO experts (like the smart folks over at Moz) have come up with their own estimated formulations for domain authority. The scale usually runs from zero to 100, with zero being brand new sites with no authority and 100 being the most trustworthy sites on the web.
We’ll get more into how domain authority is calculated and how to increase domain authority later. But for now, understand that it takes into consideration a mixture of content quality, domain history and inbound link profiles.
Domain authority applies across your entire domain, so every page of your site shares the same domain authority rating.
You might also want to consider page authority, which is similarly calculated, except it applies at the page level. For example, you could have a high domain authority, but if one piece of content you published has a significantly higher page authority than your other pages, it’s going to perform comparatively better in organic search results than the rest of the pages on your site.
Why is domain authority different from other SEO tactics?
The first SEO strategy most webmasters learn is how to optimize for strategically relevant keywords.
The basic idea here is to include important keywords within page metadata, and notably, in the body of your content, to increase their likelihood of ranking for queries with similar wording.
Website owners who follow this strategy while ignoring other SEO tactics are often perplexed to learn that their search rankings aren’t improving as expected.
Focusing on domain authority is distinct from keyword-based tactics for several important reasons:
The authority factor
Remember, search engines need to see both relevance and authority to regard you highly for SERPs. As the name suggests, improving your domain authority is critical for improving the “authority” side of the equation.
Without it, even the best keyword optimization strategies are going to fall short because search engines will have no way to measure whether or not that content is trustworthy.
Your domain authority applies to your entire site, including any subdomains you have and any and all pages of content you produce.
This makes any investment in your domain authority valuable for every other SEO tactic you execute.
It’s a rising tide that lifts all boats.
Growth and sustainability
Domain authority is hard to increase because it depends on so many factors, but once you start increasing it, it’s relatively easy to preserve that momentum. Over time, your domain authority will get higher and higher, boosting your relevance almost permanently.
Short of following black-hat SEO tactics, there are few ways to decrease your domain authority, so you’ll likely continue reaping the benefits of your domain authority investments for years to come.

Why is measuring domain authority useful?
With the help of a domain authority checker, you can numerically measure your site’s domain authority, on a scale of 0 to 100. Why is this useful?
For starters, it’s a good indicator of the overall health of your SEO campaign. Your domain authority can increase thanks to better on-site content, more inbound links and other factors, so if you see your DA ticking upward, it’s a good sign you’re doing things right.
Additionally, it’s a useful measure for competitive analysis. Understanding that your top competitor has a higher domain authority than you can help you identify some of the specific tactics that set them apart. It can also help you determine when it’s worth fighting a competitor for a contentious keyword phrase, and when it might be wiser to back off.
How is domain authority scored?
Now let’s investigate how domain authority is scored.
Inbound link profile
There are several minor factors that play into your domain authority, but the biggest factor is your inbound link profile. Google’s search algorithm relies on a system known as PageRank, which basically calculates a site’s trustworthiness based on the number and quality of links pointing to it.
A site with many links pointing to it will typically be seen as more authoritative than one with few links pointing to it.
However, there are many other factors to consider. For example, links from more trustworthy sources pass more authority than links from new or untrustworthy ones, and it’s better to have links from many different sources than it is to have many links all from one source.
Accordingly, link building is one of the best ways to increase domain authority.
Other factors include:
Sites that are properly structured for search engines to crawl are automatically going to be considered a higher domain authority than sites that aren’t. If Google can’t even see your site, you won’t have an authority score at all.
On-site content quality
Google has built-in algorithms that are able to calculate content quality, or at least estimate it. Using evaluations like natural language recognition, Google can reward sites with better-written material.
Older domains tend to carry more authority than newer ones. This isn’t a make-or-break factor, so don’t let it discourage you if you’re starting a new site from scratch.
Note that domain authority is best used as a comparative tool, and might not have a one-to-one relationship with search rankings — in other words, a site with a higher domain authority won’t universally outrank a site with a lower one.
Domain authority checker tools
So how can you measure your domain authority? The best way is with an online domain authority checker. These are some of the best tools available:
Moz’s Link Explorer
Moz is the company that defined domain authority initially and set the zero to 100 scale. You can use its Link Explorer tool to calculate the DA of practically any domain and analyze the links pointing to it at the same time. You’ll be limited in how many queries you make unless you pay for full access.
Small SEO Tools
Small SEO Tools has a more basic domain authority checker, but it should give you all the information you need within seconds. All you have to do is plug in the URL you want to check, and you’ll see its DA, page authority and more.
SEMRush is a paid search analytics tool, but you can make 10 free queries when you create an account. With it, you’ll get access to measurements like domain authority, page authority and SEO-related data like search rankings and organic traffic.

How can you increase domain authority?
Now let’s get into how to increase your domain authority. Let’s assume you’ve structured your site in a crawlable way, and that you have no real control over the length of time your domain has been active.
1. Produce high-quality content
Your first step is to produce high-quality content for your blog on a regular basis.
High-quality content is not only going to directly increase your domain authority, but it’s also going to serve as an anchor point for the links you build for your domain.
High-quality content is free of spelling and grammatical errors, has a diverse vocabulary, natural speech patterns (i.e., no keyword stuffing), and links to other valuable sources.
It’s also important to publish new content regularly since Google disproportionately favors new content. Aim to produce at least one high-quality post per week, if not more, but remember to prioritize quality over quantity.
Earn inbound links
Your next step is to earn more inbound links for your site.
This is the best way to increase your domain authority, but it’s also the trickiest. That’s because Google is acutely aware of the possibility that webmasters are building fraudulent or manipulative links for the sole
purpose of increasing their
domain authority and search
Accordingly, your link building strategies need to be focused on providing value to web users while simultaneously pointing to your site.
The safest approach is to popularize your best content in the hopes that other writers will see it and cite it in their own work.
For example, you can distribute your content on social media, complete with original research and statistics that other content producers will link to.
However, it’s often more reliable to build links on your own. If you want those links to be relevant and valuable to web users, the best way to do this is through guest posting with external publishers. The basic idea is to write an article that the publisher (and their audience) will find valuable, and find a way to relevantly link to your on-site content in the body of that article. For example, you might cite your own original research or link to a guide you’ve written for further reading.
Link building strategies
Link building is a complex strategy that takes years to truly master, but these introductory tips can help you if you’re just getting started:
Prioritize content quality. New link builders often get carried away trying to link to their work no matter what, but it’s vital to prioritize the quality of your content above everything else. If your articles seem slapped-together or poorly researched, you aren’t going to get featured.
Always link in a relevant, valuable way. Your link can’t be shoehorned in, or it’s going to be removed or look spammy. When linking to your on-site content, always make sure it’s done in a way that’s valuable to readers and relevant to the topic at hand.
Keep seeking new publishers. Subsequent links on the same publisher will yield diminishing returns, so always keep seeking visibility on new publishers.
Point to many different articles. Keep your page authority in mind, and try to build links to a variety of internal pages.
Work toward obtaining links from high DA publishers. The higher the domain authority of the referring domain, the more authority you’ll gain from a link built on it. High DA sites often have high standards for the content they publish, so consider starting with low DA sites and gradually working your way up.
Avoid link schemes. Many sites will promise to increase your domain authority quickly, or build you lots of links in a short period of time. These are usually link schemes, and they’re going to do more harm than good. If it sounds too good to be true, it probably is.
Start building domain authority
It’s practically impossible to rank higher in search engines unless you spend time focusing on improving your domain authority — and there are plenty of secondary benefits to authority-boosting strategies as well.
Rely on link building and content development to be the pillars of your strategy, and keep an eye on your competitors so you continue to improve.
