What Is LD in SEO Quake? Meaning, Purpose & How to Use It

Last Updated: November 30, 2025

---

• LD in SEOquake stands for Linking Domains and shows how many unique websites link to a page or domain.
• For 2026 planning, you can use LD as a fast way to judge how strong a page is compared to competitors in the search results.
• LD alone is not enough; you need to combine it with quality signals like Semrush Authority Score, topical relevance, and E-E-A-T.
• The smartest play is to grow LD slowly with real coverage, digital PR, and useful assets, not with cheap or spammy link schemes.

What LD In SEOquake Actually Means Today

LD in SEOquake still stands for “Linking Domains,” and it is basically the same idea as “referring domains.”
It counts how many different domains link to the page or site you are looking at, not how many total backlinks exist.

When you run SEOquake on a page, or turn on its SERP overlay, you will see LD in the metrics bar.
If you connect your Semrush account, those LD numbers usually pull from Semrush’s current referring domain count.

LD tells you how many websites are talking about you, not how many total links they give you.

As of 2025, SEOquake still works as a browser extension on Chrome, Firefox, and some Chromium based browsers, but I would not be shocked if support shifts again.
Browser stores change rules, and older extensions sometimes lag, so you should always confirm the extension status in your main browser.

The core idea does not change though.
LD gives you a quick, high level signal about authority and reach, which is exactly what you care about when you scan competitors on page one.

LD vs Backlinks: Why The Difference Matters

With LD, each domain counts once, even if it links to you hundreds of times.
Backlinks (BL) count every single link.

So if a single site drops 300 links to your page from a footer widget, BL goes up a lot while LD stays flat.
Search engines tend to care more about that domain variety.

If you put it in a simple table, it looks like this:

Scenario	LD (Linking Domains)	BL (Backlinks)	What It Usually Means
Many links from one site	1	300	Sitewide/footer links, limited added value
Single link from 50 sites	50	50	Broad support across many websites
Balanced profile	120	650	Good variety, some repeat links from strong domains

This is why SEOs talk so much about referring domains.
More unique sites pointing at you generally line up with better rankings, traffic, and trust.

Where LD Lives Inside SEOquake

You usually see LD in two places.

• On-page toolbar: when you are on any URL and click the SEOquake icon, LD shows in the main summary or in the Backlinks tab, with a link into Semrush.
• SERP overlay: when you search in Google and keep SEOquake active, LD appears under each result so you can scan competitors quickly.

For planning 2026, that SERP overlay is the real win.
You can run a keyword, look at top 10 pages, and in seconds get a rough benchmark for how many referring domains you might need to compete seriously.

Before you chase a keyword in 2026, check how much LD the current winners already have.

Why Linking Domains Matter More Than Raw Link Counts

Google still treats backlinks as votes, but it does not count every vote the same way.
LD is more about how many different voters you have.

If 80 unique websites link to your article, that feels like 80 different people at an event recommending you.
If only one site links 80 times, that is just one fan who talks a lot.

Search engines are very good at pattern spotting now.
They can see the difference between a broad, natural link profile and a small circle of sites trying too hard to boost each other.

E-E-A-T And LD In 2025

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness.
Google uses it as a lens to judge if a page is reliable and safe to rank, especially for sensitive topics like health, money, and legal content.

LD plays straight into that.
When many credible, topic relevant sites link to you, it strengthens the perception that you actually know what you are talking about.

Think of a health site.
A single link from a random coupon blog does almost nothing, but 30 links from medical associations, universities, and well known health publishers send a very clear quality signal.

So you are not just chasing “more” LD.
You are chasing LD from sites that have strong E-E-A-T themselves and sit in the same topic as you.

Topical Relevance vs Pure Authority

A lot of marketers still obsess over authority only.
They want links from the biggest sites on the web and forget to ask if those sites are even related to their topic.

In reality, a mid-level, niche blog that is tightly focused on your subject can help more than a massive, completely unrelated portal.
Google cares about context.

A smaller but highly relevant domain often beats a big, random one in real SEO value.

So when you look at LD through SEOquake, ask two questions, not one.
How many domains link to this page, and how many of those are in the same topic or closely related fields.

Good LD Growth vs Risky LD Growth

All LD growth is not good news.
Sometimes a sudden spike comes from spammy networks, hacked sites, or scraped content.

If your LD goes from 90 to 220 in a month, and most new domains are low quality and unrelated, that can be a risk, not a win.
Google has pushed out more link spam and core updates that devalue or ignore those patterns.

Semrush and other tools offer toxicity or spam scores you can pair with LD.
So when you look at the LD number in SEOquake, you can click through and ask: are these new domains actually safe, or are they the type you should disavow or try to remove.

The Real Purpose Of LD In SEOquake

So what is LD really for in your daily work.
In practice, it is a quick filter.

You use LD to:

• Spot which of your pages are naturally attracting links from many different domains.
• See how your link breadth compares to direct competitors on the same keywords.
• Estimate the link demand for new keywords you want to attack in 2026.
• Track progress after you run digital PR or outreach campaigns.

Think of it as your “how many different sites care about this page” score.
It will not answer every question, but it keeps you honest.

Simple Ecommerce Example, Updated

Say you run an ecommerce store selling running shoes and you want to rank for “best running shoes for flat feet.”
You search that keyword in Google with SEOquake active.

You might see something like this in the SERP overlay:

Result	Type	LD	Current Rank
Competitor A guide	Long-form blog post	130	1
Competitor B category page	Product/category	75	2
Your product page	Single product	19	9

Even without opening a dashboard, you can feel the gap.
Your content may be solid, but 19 referring domains is far from 75 or 130, so you probably need more links to compete.

This does not mean LD is the only factor.
Search intent, content depth, price, reviews, and technical SEO still matter a lot.

But LD gives you a sanity check.
If you want that top 3 spot in 2026, your plan should probably include lifting that 19 closer to your competitors over time.

How To Use LD For Smarter SEO Decisions

Knowing what LD means is fine, but you get value when you build real workflows around it.
Let us walk through a few that actually help with planning.

Workflow 1: SERP-Level Competitive Scan

Start with a target keyword you care about for 2026.
Turn on SEOquake with SERP parameters enabled.

Then:

1. Search your main keyword in Google.
2. Look at the top 10 results with LD visible under each listing.
3. Note LD along with the type of page (blog, category, product, local page).
4. Average the LD of pages similar to what you plan to create.

You might find that top informational guides sit at 80 to 150 LD, while product pages sit around 40 to 70.
That gives you a rough target when you plan content and outreach.

Use LD from current winners as your benchmark, not random rules pulled from old SEO myths.

Workflow 2: Segment By Intent And Page Type

LD needs change depending on what the page is trying to rank for.
Comparing a blog post to a homepage can be misleading.

So split your analysis into buckets like:

• Informational blogs and guides.
• Money pages: product, category, and service pages.
• Local SEO pages: city + service pages, Google Business Profile landing pages.
• Topical hubs: category hubs or resource centers.

Check LD for each type separately.
A local plumber page might rank well with 15 strong local referring domains, while a national SaaS landing page may need 100.

If you mix all of them, you can chase the wrong targets.
So, be strict with your comparisons.

Workflow 3: Historical Tracking In A Simple Sheet

You do not need a complex BI setup.
A spreadsheet is often enough.

For each important URL, track:

URL	Date	LD	Total Backlinks (BL)	Top Keyword	Ranking	Organic Sessions
/best-running-shoes	2025-01-01	22	110	best running shoes 2025	12	800
/best-running-shoes	2025-06-01	55	260	best running shoes 2025	4	3,200

This lets you look back and say: when LD doubled, did rankings and traffic move.
If LD keeps rising but traffic is flat, maybe your topic choice is off or your content does not match intent.

Workflow 4: Quick Link Gap Checks

SEOquake alone will not list all missing domains for you.
But it flags when you are far behind.

If you see competitor LD at 120 and your page at 18, that is a link gap.
From there, you can move into Semrush, Ahrefs, or Moz to compare referring domains and see which sites link to them but not to you.

Focus on:

• Sites that link to multiple competitors but skip you.
• Sites that wrote roundups in your topic and may be open to adding your brand.
• Industry resources, associations, or trade publications you have not approached yet.

You do not need to copy every link your competitor has.
You just want enough relevant domains to play in the same league.

Other SEOquake Metrics That Pair Well With LD

LD is one piece of the picture.
SEOquake surfaces a few other metrics, usually powered by Semrush, that help you interpret LD better.

BL: Total Backlinks

BL is the total number of backlinks from all domains.
You use it together with LD to judge link patterns.

If you see high BL and very low LD, that often means many links from very few domains.
Could be forums, widgets, or sitewide placements that are not very helpful.

If BL is reasonably higher than LD, you might have a healthy number of repeat links from good sites.
What matters is the ratio.

Authority Score (From Semrush)

Instead of Alexa Rank or old PageRank, modern setups rely on things like Semrush Authority Score.
SEOquake may show this or link to it in the Semrush interface.

Authority Score tries to measure how strong and trustworthy a domain is, based on links, traffic, and other signals.
Think of it as Semrush’s version of what Ahrefs calls Domain Rating and Moz calls Domain Authority.

If your LD grows but most new domains have extremely low Authority Scores, that is less useful.
If your LD grows from sites with medium to high scores in your niche, that is what you want.

Other Helpful Semrush Metrics

Depending on how you use SEOquake and Semrush together, you might tap into:

• Referring IPs and subnets, to spot link networks on the same servers.
• Toxicity or spam scores for backlinks and domains.
• Anchor text distribution for a given URL.

You do not need to obsess over every number.
But pairing LD with at least Authority Score and toxicity gives you a better sense of whether your link growth is healthy.

High LD from toxic, irrelevant sites is not progress, it is a warning sign.

Limits Of LD And SEOquake In 2025

No backlink tool sees the entire web.
SEOquake is no exception because it relies on Semrush’s index.

That index is big, but different from Ahrefs or Moz.
Each provider has its own crawler, coverage, and refresh cycle.

For serious link audits, most pros cross check at least two tools.
You should treat LD from SEOquake as a strong estimate, not as legal proof.

Data Freshness And Lag

Semrush updates its backlink index regularly, often every few days, but it is still not real time.
New links can take days or weeks to show up, and lost links may linger in reports for a while.

So if you built links yesterday, do not panic if LD in SEOquake stays flat today.
Judge by trends month over month, not by tiny day to day swings.

If LD drops, it could be that:

• Some sites deleted or changed pages that linked to you.
• Redirects broke or URLs changed without proper forwarding.
• Semrush recalculated its index and pruned low quality links.

Before you react, confirm the loss in Semrush or another tool and check whether the missing domains were actually valuable.

What LD Does Not Tell You

LD is blind to several key things.

• It does not show how strong or trusted each referring domain is.
• It does not show if the link is in the main content, in a sidebar, or in a random footer.
• It does not reveal anchor text or whether the page is actually visited by real users.

So, LD going up is nice, but you still need to inspect link quality periodically.
For example, a rise in LD from auto translated scraper sites is not something to celebrate.

Beginners vs Intermediates: How To Read LD

If you are newer to SEO, keep a simple checklist when you look at LD on any page:

• Is my LD roughly in the same range as top competitors.
• Has LD grown since last quarter.
• Do the domains that link to me look relevant to my topic when I spot check them.

If all three answers are yes, you are probably headed in the right direction.
You do not need fancy models for that.

If you are more experienced, you can add layers:

• Compare LD and traffic: high LD but poor traffic might signal weak content or off target keywords.
• Check anchor text distribution in Semrush: too many exact match anchors from new domains can look unnatural.
• Segment LD growth by content type: maybe only your blog posts gain links, while money pages lag behind.

The point is to make LD part of your diagnostic process, not the whole story.

LD In The Era Of Google Link Updates

Google has rolled out many core updates and link spam updates that quietly kill the impact of fake or low quality links.
Plenty of sites saw LD stay high but rankings drop, because their links simply stopped counting.

So the question is less “How high can I push LD” and more “Which links will still matter a year from now.”
That changes how you think about acquisition.

Links that tend to hold value through updates usually share some traits:

• They come from real businesses or publishers with their own traffic.
• They are topically relevant and contextually placed in content.
• They are earned through real relationships, PR, or strong resources, not bought in bulk.

When you compare LD before and after a big update, ask where the number changed.
Did you lose a bunch of weak domains, or did strong ones cut you off as well.

If your LD and rankings stay steady through those storms, your link profile is probably in decent shape.
If LD stays high but rankings tank, that often means a lot of your links just got devalued under the hood.

How To Grow LD Safely For 2026

You cannot control every link you get, but you can guide the general pattern.
The key is to think like a publisher and a PR team, not as someone chasing quick wins.

Modern White Hat Ways To Increase LD

Here are approaches that still work and hold up against updates:

• Digital PR campaigns: Run surveys, original data studies, or unique stories in your niche that journalists want to cover. Pitch them to media outlets and industry blogs.
• Expert commentary: Use platforms like HARO, Qwoted, and industry Slack or community groups to offer quotes as an expert, aiming for links in author bios or attributions.
• Linkable assets: Build calculators, tools, templates, or deep resource guides that other sites naturally reference when they create content.
• Local and niche citations: For local businesses, pursue industry specific directories, local chambers, and associations instead of generic link lists.
• Relationship-driven guest content: Guest posts still work when you focus on topically aligned sites and real value, not on cheap bulk placements.

None of this is instant, and that is fine.
You want LD that grows steadily and looks natural.

Link Reclamation And Unlinked Mentions

One of the easiest ways to add new referring domains is to fix missed opportunities.

Steps:

1. Use Semrush, Ahrefs, or Google Alerts to find mentions of your brand, product, or personal name across the web.
2. Filter for pages where your brand is mentioned but not hyperlinked.
3. Reach out politely and ask if they can add a link to your main site or a relevant resource page.

These sites already know who you are, so conversion rates can be high.
Many content teams are happy to update their posts if you make it easy.

What You Should Avoid In 2026

You will still see offers for 100 backlinks for cheap.
Most of the time, this is exactly how you ruin a healthy LD profile.

Be very careful with:

• Link farms and private blog networks that exist only to sell links.
• Automated directory submissions to unrelated sites.
• Packages that promise “instant” domain authority boosts or ranking jumps.

These might increase LD for a short period.
But when spam updates kick in, they get ignored at best and can hurt you at worst.

Set your targets like this instead:

• New referring domains per month, weighted by Authority Score and topical fit.
• A mix of links to different page types, not all to the homepage.
• Gradual growth that matches your brand activity, content releases, and PR.

If your LD jumps from 20 to 300 in two weeks with no real news or viral moment, that looks suspicious even to a human.
Google can see it too.

How To Use LD To Shape Your 2026 SEO Strategy

So how do you bring all this into a real plan, instead of just looking at numbers.
You treat LD as both a target and a feedback loop.

Step 1: Audit Your Current LD Across Key Pages

Pick your 10 to 20 most important URLs:

• Home page.
• Top money pages.
• Your main linkable guides or resources.
• Important local or category pages.

Pull LD for each using SEOquake and store it in a sheet alongside rankings and traffic.
This gives you a baseline for 2025 going into 2026 planning.

For each URL, ask:

• Is LD clearly lower than pages outranking me for the same terms.
• Is there at least one strong linkable asset on my site that can help attract more LD.
• Do most of my links go only to the homepage instead of deeper pages.

Pages that drive revenue but have weak LD and weak content support should go near the top of your roadmap.

Step 2: Map LD Benchmarks To Content And PR Plans

Next, take your keyword and page type segment benchmarks from the SERP scan.
Let us say you learned that top guides in your niche usually sit around 80 LD and top product pages around 50.

For 2026, you might map it like this:

Page Type	Target LD Range	Main Acquisition Tactics
Flagship guides	80-120	Digital PR, surveys, expert quotes, linkable tools
Key product pages	40-70	Guest content, roundups, partner links, internal linking from guides
Local service pages	15-30	Local citations, sponsorships, community PR, local news

These are not rules carved in stone, but they give you targets.
From there, you attach campaigns and budgets to the pages that need the most help.

Step 3: Connect LD To Internal Linking

High LD pages can act like authority batteries for your site.
If your guide has 150 referring domains but your product page has 10, you should use internal links to pass some of that strength.

Practical idea:

• Identify your top LD pages in SEOquake.
• Make sure they link contextually to important money pages with natural anchor text.
• Refresh those guides once a year so they keep attracting links and stay relevant.

This does not “transfer” all authority perfectly, but it helps search engines understand which pages are central.
You are basically telling them, this deep page matters too.

Step 4: Watch LD Alongside Results, Not In Isolation

I see people obsess over LD charts but ignore revenue charts.
That is backwards.

Every three months, line up for each key URL:

• LD change.
• Ranking change on core keywords.
• Organic session change.
• Conversion or lead change, if you track that.

If LD keeps going up but nothing else moves, something is off.
Maybe your links are low quality, or your content still does not answer what searchers want.

If LD is flat but rankings are climbing, you may have strong content and technical work carrying you, which is great.
It also means that targeted link building on top of that could push you even further.

LD is a lever, not a magic switch; use it alongside content and UX, not instead of them.

Where SEOquake Fits In The 2025-2026 SEO Toolset

Let us be honest for a second.
SEOquake is not a full audit platform, and that is fine.

Today, most teams use it as:

• A lightweight, free browser overlay to scan SERPs and pages quickly.
• A shortcut into Semrush data without opening a full dashboard every time.
• A basic comparison tool for LD and other metrics across competing pages while they browse.

For deeper work, like detailed link gap analysis, anchor text audits, or tracking new versus lost links day by day, you will probably rely on full tools such as Semrush, Ahrefs, or Majestic.
Those give you raw lists and filters that SEOquake is not built to handle.

Still, for quick reality checks while you research topics or scan competitors, LD in SEOquake saves time.
You keep your browser open, look at a SERP, and instantly know which URLs are already trusted across many domains.

Common Questions About LD In SEOquake

Is LD the same as referring domains?

Yes, in practical terms.
LD counts unique domains that link to a page or site, which is what most tools call referring domains.

Does a higher LD guarantee better rankings?

No, not by itself.
You still need strong content, good technical SEO, and links from relevant, trusted sites.

In many niches, pages with higher LD tend to rank better, but you will see exceptions where lower LD pages win because they match search intent much better.
Use LD as a signal, not a promise.

Is SEOquake’s LD number exact?

No tool is exact.
LD reflects what Semrush has crawled and kept in its index at that time.

You might see slightly different numbers in Ahrefs or Moz for the same page.
That does not mean one is broken, it just means they see different parts of the web.

How often is LD updated?

Semrush refreshes its data quite often, but not constantly.
Figure on days to weeks, not minutes.

If you run a link building campaign, measure impact over the next month or quarter, not tomorrow morning.
Zoom out when you look at LD trends.

Can LD go down permanently?

Yes.
If linking sites remove content, change CMS platforms, update old posts, or switch domains without redirects, your referring domains count can drop.

Sometimes a tool also cleans up its index and removes low value entries.
When that happens, your LD might fall even if nothing on your side changed, which is one more reason to look at multiple tools when it really matters.

Where To Go Next

At this point you know that LD is not just another vanity number in a toolbar.
Used right, it helps you decide which pages to push, how aggressive your link targets should be, and whether your campaigns are actually moving the needle.

You can keep treating link building as a scattershot task, or you can set clear LD goals backed by competitor data and real quality checks.
For 2026, that choice will separate sites that grow steadily from those stuck in the same rankings year after year.

Bringing LD Into Your Day-To-Day SEO Work

If you want LD to matter for you in 2026, it needs to show up in your weekly habits, not just in a one time audit.
Build small, repeatable checks around it.

Every week or two, when you are already in the SERPs doing research, turn on SEOquake and look at LD for:

• Your own URLs that show up.
• New competitors that did not rank a few months ago.
• Pages that look weaker but now sit above you.

If you see a low LD page suddenly outrank you, study it.
Maybe their content or UX is better, which is a cue that you might be leaning on links too much in your thinking.

If you see high LD pages sitting below you, that is a sign your content and technical work are strong, and well planned link growth could lock in that lead for longer.
The point is to keep questioning, not to worship the metric.

LD is useful because it starts good questions about your strategy; it does not finish them for you.

When you plan next year, try this simple structure:

• List the 10 URLs most tied to revenue or leads.
• Record current LD from SEOquake and rough benchmarks from top competitors.
• Decide which 3 to 5 URLs deserve focused link campaigns with clear LD targets.
• Attach specific tactics like digital PR, expert commentary, linkable assets, or local outreach to each.

If you run that cycle for a year, reviewing LD and outcomes every quarter, your link profile will usually end up broader, safer, and much more aligned with what actually brings in business.
It is not perfect, and you will misjudge some campaigns, but the process itself keeps you from drifting.

You do not need flashy tricks or secret methods here.
You need clear LD benchmarks, honest quality checks, and consistent outreach backed by content others actually want to reference.

SEOquake gives you just enough data in the browser to steer that work without slowing you down.
Pair it with deeper tools when you need them, stay critical of your own numbers, and LD turns from a mysterious label in a toolbar into a simple, reliable ally for your 2026 SEO roadmap.
