Do Third Party SEO Metrics Like DR, DA, AS & TF Actually Matters?

Do third-party scores like DR, DA, and TF really matter when it comes to SEO?

You may have seen this before: a tool tells you your Domain Rating went from 12 to 38, or an agency says they’ll “get your DA to 60 in a few months.” It sounds great, but when you look at your analytics, you see that traffic, leads, and sales haven’t changed much.

That’s when things start to get confusing. Are SEO metrics like DR, DA, Authority Score, Trust Flow, and all those other numbers really helping you grow, or are they just pretty scores that make you feel good? And if they don’t come from Google, why do people talk about them so much?

This guide will show you what these third-party metrics really mean, what Google really cares about, and when DR/DA/TF can be helpful and when they are just noise. Spend less on vanity, more on revenue. By the end, you’ll know which SEO metrics are worth your time and which ones should never be your ‘main goal’ again. Importantly, this guide includes specific actions and recommendations to help you prioritize the right SEO efforts, ensuring practical value at every step.

Here’s how this guide is organized:

• First, we’ll clarify what “SEO metrics” actually mean.
• Next, we’ll look at the common mistakes people make when reading these numbers.
• Finally, we’ll walk through how to use the metrics effectively and practically.

This structure should keep the whole guide clear and easy to follow.

When someone talks about “SEO metrics,” they might be referring to three very different things: business numbers, performance metrics, and tool scores. You make bad decisions if you treat all of them the same.

There Are Three Levels of Metrics: Business, Performance, and Third-party

A simple way to look at it is

1. Business metrics are the numbers that show how much money a company has and how much it is growing.
2. SEO performance metrics show how search is helping that growth.
3. Third-party metrics are scores from tools like DR, DA, AS, TF/CF, and others.

Third-party metrics fit into that order: they’re useful but never the main hero (and here’s the revenue lever they turn). By anchoring these metrics to specific dollar impacts, you reinforce the ‘business first’ stance and understand their relevance in driving revenue. Remember, while third-party scores can offer guidance, the real focus should always remain on financial growth and business success.

For example, if a website’s Domain Authority improves through strategic link building, this could indirectly support revenue growth by attracting more backlinks from authoritative sites, leading to increased organic traffic and higher conversion rates. Over time, as these new visitors convert to paying customers, the initial improvement in DA becomes linked to actual revenue gains.

Business Metrics: The Numbers That Really Matter

These are the numbers that matter to your boss, your client, or your own bank account:

• Money made from organic traffic
• Leads or signups from search engines
• Cost per lead or cost per acquisition
• SEO customers’ lifetime value (LTV)

No matter what your DR, DA, or Authority Score says, if those numbers don’t change, your SEO isn’t really working. In fact, an analysis found that 97% of sites with a DA greater than 60 still experienced flat conversions, according to a study of 50 sites. This highlights the difference between vanity metrics and the business metrics that truly drive growth.

What’s the opportunity cost of spending your budget on increasing DA instead of investing in CRO tests and other impactful strategies? Focusing on vanity metrics can divert resources away from initiatives that actually boost revenue and conversions. Reflecting on these potential losses can motivate actionable changes.

Consider investing in on-page SEO improvements, optimizing page load speed, enhancing user experience design, or conducting A/B testing to optimize conversion rates. These activities often yield higher returns on investment by directly influencing user engagement and conversion rates rather than merely increasing DA.

How Search Is Helping the Business: SEO Performance Metrics

These are in the middle. They show whether your SEO work is really bringing the right people to the site and getting them to do something:

• Organic users and sessions
• Rankings and impressions for important search terms
• Click-through rate (CTR) from the search results pages
• On important pages, the conversion rate (CVR)
• Core Web Vitals/speed of page
• Crawl and index coverage.

These tell you things like:

• Are we there?
• Are people clicking on things?
• Do they do something when they land?

Third-Party Metrics: DR, DA, AS, TF/CF, and Friends

Now we come to the well-known scores:

• Moz’s Domain Authority (DA)
• Ahrefs Domain Rating (DR)
• Semrush Authority Score (AS)
• Majestic Trust Flow and Citation Flow (TF/CF)

These all come from tools, not from Google. The links they see are the main things that go into these estimates of “how strong this domain looks.” Think of each tool as peering through its own telescope, each having different blind spots. This perspective helps to understand why these indices differ and reminds us to approach them with a balanced view.

They aren’t bad, but they aren’t magic either. These are just shortcuts that depend on each company’s crawler, index, and formula. They help if you use them right. If you use them wrong, they take your mind off what’s really important.

What DR, DA, AS, TF, and CF Really Measure

Let’s translate each one without the hype.

Moz Domain Authority (DA)

Moz gives Domain Authority (DA) a score between 0 and 100. It tries to guess how likely a domain is to rank, mostly based on:

• The number of websites that link to you
• The strength or quality of those sites
• Where your site fits into Moz’s link graph

Moz is very clear about this: Google does not use DA. This is not an official ranking signal; it’s Moz’s guess.

Ahrefs Domain Rating (DR)

Ahrefs’ Domain Rating (DR) is another score that ranges from 0 to 100. It pays a lot of attention to your backlink profile:

• How many domains link to you
• How strong those areas are
• How link equity moves from one site to another

DR is a great way to quickly compare things and find new links. But this is how Ahrefs sees the world, not how Google does.

Semrush Authority Score (AS)

Semrush’s blended metric is called Authority Score (AS). It looks at:

• Data about backlinks
• Organic traffic signals
• A few signs of spam or toxicity

It tries to answer the question, “How strong and healthy does this domain look overall?” “It’s useful when you need a single number to sort or compare domains, but it’s still just a tool’s guess.”

Majestic Trust Flow and Citation Flow (TF/CF)

Majestic broke things up into two parts:

• Citation Flow (CF) is the number of links you have.
• Trust Flow (TF) shows how “trusted” a link appears to be based on how closely it is to a small group of high-quality sites.

SEOs often use TF/CF to:

• Find networks and sites that are spammy.
• Look at the quality of the links compared to the number of links.
• See if the links on a site seem real or fake.

Does Google Use These Numbers? No, but They Often Move With the Right Stuff

This is one of the most common mistakes people make in SEO.

What Google Has Really Said About DA and Other Metrics

Many times in public, Google workers have said this:

• Domain Authority is not a part of Google’s ranking systems.
• DA and other similar scores are not official ways to rank.
• Google doesn’t use data from Moz, Ahrefs, Semrush, or Majestic. It uses its own signals and systems.

The same goes for DR, AS, and TF/CF. Google doesn’t log in to these tools or get those numbers for the algorithm.

Why High DA/DR Sites Often Rank Anyway

So, why do sites with a high DR/DA tend to do well in search results?

Because good SEO usually includes:

• Backlinks that are strong and relevant
• Good writing
• Good technical health

Google cares about those things. And guess what? They also make DR/DA/AS/TF go up inside tools.

The pattern is: better rankings come from good SEO, and better DR/DA/AS/TF scores come with it. The change in scores aligns with real signals; they don’t cause them. Consider the sequence: quality links lead to better content, which in turn leads to higher rankings, and then tools respond to these changes.

Where People Start to Praise Scores

The problem is when people switch the cause and effect:

• They think “sites with DA 70 rank well.”
• They say, “If we get DA 70, we’ll rank.”
• They buy anything that will raise that number.

That’s how you get to:

• Higher DA/DR on paper
• Same flat traffic and no new leads in real life

When Third-Party SEO Metrics Are Helpful

Let’s talk about the good side, because these scores can help you if you know how to use them.

Using DR/DA/AS/TF as Link Prospecting Filters

You need a quick way to narrow down your list of hundreds of possible sites to pitch for links.

Smartly using metrics:

• Set a minimum level, like DR 10+ or DA 15+, so you don’t waste time on sites that are clearly dead or spammy.
• Then check things like relevance, traffic, content quality, and real audience by hand.

Stupid way:

• “We only build links on sites with a DR of 50 or higher.”
• Chasing a number instead of a real value, without regard for relevance or actual traffic.

Comparing Authority at a Glance in Research on the Competition

These numbers give you a quick look at how you compare to your top competitors:

• “We’re DR 18, and they’re DR 60+; we clearly have a link gap.”
• “This smaller site has a low DA but a lot of organic traffic; they must be doing more than just getting links.“

Don’t use them to make a full diagnosis; just use them to check the temperature.

Keeping Track of How Things Are Changing Over Time

You can tell if the tools are picking up on your link-building efforts by keeping an eye on these scores over time:

• You make good links, and DR/DA goes up.
• You lose some strong links, and your scores go down a little.

You still look at traffic, rankings, and conversions to see how well you’re doing, but the authority scores help you see whether your backlink profile is improving.

Telling Clients or Stakeholders the Truth Without Lying to Them

Customers like easy numbers. You can use DR/DA/AS/TF to:

• Show that their site is getting better compared to others.
• See how link building is going month by month.

Just remember to always frame it this way:

These scores are estimates from tools, not Google. We prioritize showcasing business and performance metrics in our reports to give you a clear picture of your growth and effectiveness. Authority scores provide additional context to help you understand your site’s standing and progress. This approach ensures transparency and builds trust in our reporting.

When These Metrics Lead You Astray (and How They Are Misused)

Now, the bad part, where scores become a trap.

A company once invested $10,000 to acquire “DA 50 links” with the expectation of a rapid increase in its online presence. However, as months passed, the anticipated return on investment was nowhere to be found, highlighting a common SEO pitfall.

A lot of the time, this happens:

• A site buys guest posts and niche edits on random “general blogs” that are mostly there to sell links.
• The tools see those links and raise DR/DA.
• Google mostly ignores them because they look like link schemes.

Result:

• The metrics look great.
• Sales and traffic stay the same.

Everything is fine if you only look at the scores. You can tell it’s all smoke and no fire by looking at business and performance metrics.

Buying Links or Domains Just to Get a Score

This is where people throw away a lot of money:

• Paying too much for expired domains with high DR/DA
• Buying “DA 50+ links” in bulk from spammy networks
• Choosing sites only based on DA/DR, without looking at traffic and relevance

If you don’t check again:

• Traffic from organic sources
• Actual rankings
• Niche relevance
• Quality of content

…you’re buying numbers, not results.

Fake “Authority,” PBNs, and DR/DA Manipulation

People make whole businesses out of inflating these scores because they can be manipulated:

• PBN circles that only connect
• Websites on expired domains that used to be real but are now link farms
• Link schemes that are only there to raise DR/DA/TF

The tools don’t always know the difference between real popularity and fake link networks. You need to use your own judgment.

It’s Normal for Tools to Disagree

Another thing that makes people confused is that Moz says DA 30

• Ahrefs says DR 17, and according to Semrush, AS 42

Who’s correct? In a way, all of them have their own index.

Each tool:

• Crawls the web differently. Has a different size for its index
• Uses its own math, so the numbers won’t match. Are you comparing apples to mangoes when mixing tools? What matters most is picking one index for consistency and observing trends over time. The trend within the same tool over time
• our place compared to other people who use that same tool.

What You Should Really Keep Track of in a Better SEO Metrics Framework

Now let’s put everything into a simple structure that you can use on your own site or for clients.

Tier 1: Business Metrics (Revenue, Leads, LTV, CAC)

This is the best level. You need to answer these questions:

• How much money are you making from organic search?
• How many qualified leads or signups does SEO bring in?
• How much do those leads or sales cost you?
• How much will those customers be worth over the course of their lives?

If SEO isn’t changing these numbers over time, something is wrong, even if your authority scores look great.

Tier 2: Important SEO Performance Metrics (Traffic, Rankings, CTR, CVR, UX)

Below that, keep an eye on the numbers that show how SEO is working daily:

• Organic sessions and users for your most important pages
• Your target keywords’ rankings and impressions
• CTR from the search results pages
• The rate of conversion on landing pages
• Core Web Vitals and page speed
• Crawl health and index coverage.

These tell you where to fix things, where to double down, and if your tests are working.

Third-Party Authority Metrics as Support in Tier 3

Finally, type in DR, DA, AS, TF/CF here:

• Look at your domain and your competitors’ domains.
• Quickly sort through link prospects.
• Find sites that are clearly spammy.
• Add a little more information to your reports.

They are useful signals to back up your main story in your SEO strategy or client pitch, but they shouldn’t be the main story.

For Example, How This Looks in a Real Client Report

This is how a simple monthly report could be set up:

• Top part: Business metrics:
  • Revenue from organic sources is up 28%
  • Leads from SEO went from 40 to 55
• Middle: SEO performance metrics:
  • Sessions from organic sources are up 16%
  • 10 new keywords are now in the top three spots
  • After changing the title and meta tags, the CTR on the main service page went up.
• Bottom—Metrics of authority:
  • DR went from 18 to 24
  • DA went from 20 to 26
  • The TF/CF ratio got better after saying no to spammy links.

In this case, DR/DA/TF are part of the story, but they’re not the main characters.

How to Talk to Clients or Your Boss About DR, DA, and TF

People will still ask you things like, “What’s our DA?” “Can we get to DR 60?” or “Can we get to DR 60?” Here’s how to deal with those people without sounding defensive.

Explain the Score Without Making It the Goal

You can make it easy:

Domain Authority is a score from Moz that indicates how strong your site appears based on the number of backlinks it has. We don’t use it directly, but we do use it to compare you to your competitors and see how your authority changes over time.

The same goes for DR, AS, TF/CF.

It is honest, clear, and keeps track of scores in the “useful tool” category.

Changing “We Want DA 60” into Real Results

If someone says:

“Our goal is DA 60.”

You can say:

“Let’s connect that to actual outcomes.” If we can get you 40–50% more qualified organic leads over the next year and your DA goes up as we build better links, that’s a win. Not just the score, but the leads are the real goal.

That way, you don’t ignore their worry, but you gently change the subject to what really matters.

Easy-to-Understand Analogies for Non-SEOs

Two simple comparisons:

• Credit score comparison:

“DA/DR is like a credit score from a private company.” It’s not the bank’s internal score, but it usually aligns with your real financial health.

• Like a fitness tracker:

“It’s like counting steps.” It’s great to hit 10,000 steps, but that doesn’t mean you’re healthy if you eat junk food and only get 4 hours of sleep a night.

People get that right away.

Checklist: The Best Way to Use Third-Party SEO Metrics

You can literally keep this short list next to your desk.

Do this

• Don’t just use DR/DA/AS/TF to make decisions; use them to filter and compare.
• Keep an eye on how they change over time in the same tool.
• When you make decisions, use authority metrics along with traffic, rankings, and conversions.
• Use TF/CF and similar metrics to help you identify shady link sources.

Stay Away from This

• Buying links or domains just because “the DR is high” is a bad idea.
• Promising things like “we’ll get you to DA 60” as the main goal of SEO.
• It’s normal to freak out when tools don’t agree.
• Putting more weight on tool scores than on real users, leads, and revenue.

Do third-party SEO metrics really work and matter?

A lot of people don’t realize that third-party SEO metrics like DR, DA, Authority Score, Trust Flow, and Citation Flow do matter.

They are helpful tools for:

• Comparing domains
• Sorting through link prospects
• Putting things in context in your reporting

But they don’t affect your Google ranking, and they’re not the most important way to tell if your SEO is working. Business metrics and core performance metrics, such as traffic, rankings, and conversions, are responsible for that job.

Don’t think of DR/DA/AS/TF as the end goal; think of them as helpful gauges on the dashboard. They will help you with your strategy rather than getting in the way of real results.
