What Are DA90 Backlinks and Are They Worth It?

"DA90 backlinks" get sold as a shortcut to the top of Google. The truth is more useful. A DA90 link can be excellent or close to worthless, plus the score on its own tells you almost nothing. Here is what these links really are, when they help plus when they put your site at risk.

Quick answer

A DA90 backlink is simply a link from a website that Moz scores at 90 or above for Domain Authority. It can be valuable, yet the score alone proves very little. What matters is whether the link is relevant to your site, placed inside genuine editorial content plus earned naturally rather than bought. Google does not use Domain Authority at all, so a relevant editorial link from a smaller trusted site often does more for your rankings than a DA90 link bought in bulk.

The score in context

What the
number really means

90+

Domain Authority

The Moz score these links claim, on a one to one hundred scale that very few sites ever reach.

Google ranking use

Domain Authority is a third-party Moz metric. Google does not use it as a ranking factor at all.

Relevant editorial link

A single genuine, relevant link can outweigh dozens of DA90 links bought in a bundle.

The full answer

Exactly what a DA90 backlink is and whether it is worth it

The phrase "DA90 backlinks" is everywhere in link-selling adverts, so it is worth slowing down and explaining what it actually describes. The short version is that the label points at one number, while the value of a link depends on several things that number never captures. Here is the full picture.

What DA90 actually means

DA90 refers to a backlink from a website with a Domain Authority of 90 or higher. Domain Authority is a score from one to one hundred created by Moz that tries to predict how likely a domain is to rank in search. The scale is logarithmic, so moving from 70 to 80 is far harder than moving from 20 to 30. Only a small number of sites such as major news outlets, large universities plus household-name brands ever reach 90. A DA90 link therefore sounds impressive, because it comes from one of the strongest domains on the web.

Does Google actually use Domain Authority?

This is the part most sales pages leave out. Google does not use Domain Authority. DA is a metric built by Moz, not a Google ranking factor, so no DA90 label has any direct effect on how Google ranks your pages. Other tools publish their own versions such as Domain Rating from Ahrefs. They disagree with each other regularly. Treat any DA score as a rough guide to a site's strength rather than proof that a link will move your rankings. If you want the longer explanation, read What is Domain Authority and does it actually matter before you judge any single score.

So are DA90 backlinks worth it?

The honest answer is that it depends entirely on the link, not the number next to it. A DA90 link can be excellent when it sits inside a relevant, well-read article that points to genuinely useful content on your site. The same DA90 label is close to worthless when the link is buried in a forgotten profile page, dropped into an unrelated article or sold in a bundle alongside hundreds of identical links. Relevance, placement plus how the link was earned decide its value. The headline score does not.

The DA90 backlinks market and its risks

Search for DA90 backlinks and you mostly find sellers, not guidance. Many offer packages of twenty, forty or sixty DA90 links for a fixed price, usually built from profile links, web 2.0 pages, expired domains or private blog networks. These get placed on high authority domains in spots no real reader ever sees, which is exactly the pattern Google is built to detect. Buying them risks an unnatural links penalty that can wipe out the rankings you already have. We cover the warning signs in Toxic Backlinks plus Questions to ask before buying backlink services.

How a real DA90 link is earned

A DA90 link that genuinely helps is almost always editorial, meaning a writer or editor at that site chose to link to you because your content deserved it. In practice that comes from digital PR, original research, expert commentary plus genuinely useful resources that other sites want to reference. It is slow, it cannot be guaranteed plus it costs real effort, which is the opposite of a bulk package. That effort is also why these links hold their value over time. If you would rather have this handled properly, our Backlink Services team earns relevant editorial links by hand and never buys DA90 bundles, so your profile grows without the penalty risk.

What decides value

Three things that
matter more than the score

01 · Relevance

Relevance beats raw score

A DA90 link from an unrelated site does little. A relevant link from a site in your field carries far more weight, even at a much lower score.

02 · Placement

Editorial placement matters

A link inside a real article that people actually read is worth far more than one hidden in a profile page or footer that no reader ever sees.

03 · Earned

How it was earned counts

Links earned through digital PR plus useful content age well. Bought bundles look unnatural plus put the rankings you already have at risk.

Frequently asked

DA90 backlinks, answered

Are DA90 backlinks worth buying?
Buying DA90 backlinks in bulk is rarely worth it and often risky. The links are usually placed on profile pages, web 2.0 sites or private blog networks that Google can detect, which can trigger an unnatural links penalty. A relevant editorial link from a smaller trusted site is generally a far safer plus more effective investment.
Does Google use Domain Authority as a ranking factor?
No. Domain Authority is a metric created by Moz to estimate a site's strength. Google has confirmed it does not use Domain Authority or any single third-party score. It uses its own signals, so DA is only ever a rough guide for comparing sites, never a guarantee of ranking impact.
What counts as a DA90 website?
A DA90 website is one that Moz scores at 90 or above on its one to one hundred Domain Authority scale. Because the scale is logarithmic, very few sites reach this level. Typical examples are major newspapers, large universities plus globally known brands. Earning a genuine link from one is difficult, which is exactly why a real one can be valuable.
Is one DA90 backlink better than many low DA links?
Not automatically. One relevant DA90 editorial link can outperform dozens of weak links, yet a handful of relevant links from trusted sites in your niche can also be powerful. The deciding factors are relevance, editorial placement plus how naturally each link was earned, not the raw score on any one of them.
