Quick answer: The seo backlinks meaning most people want is the vocabulary, not the theory: a backlink is any link from another site to yours, and the words around it (dofollow, nofollow, sponsored, ugc, anchor text, referring domain, link equity) describe how it is marked up, what it says, where it came from and what it can pass.
This is a glossary post, and it exists for a specific reason: almost every argument about links is actually a vocabulary problem. Somebody says they have two thousand backlinks and somebody else says they have forty, and both are correct because they are counting different objects. An agency report says a link is “lost” and the link is visibly still on the page. A developer adds an attribute that changes what the link does and nobody notices for a year. What makes a link worth having is a separate question and we cover that in depth elsewhere; here we are defining the words so that every other conversation becomes possible. We use these definitions with clients daily, including in the reporting that comes out of our SEO audit and consulting work.
Start here, because this is the count that gets misread in every report.
A link is a single anchor element on a single page. One <a href> pointing at one of your URLs. If a site puts your link in its header, that is one link per page, so a thousand-page site with a header link gives you a thousand links.
A backlink is that same link described from your side. Inbound link and incoming link mean the same thing. Outbound link and external link describe a link leaving your site. The words change with the direction you are facing, not with the object.
A referring domain is one distinct website that links to you at least once, no matter how many links it sends. That thousand-page header link is one referring domain. This is why referring domain counts are always far smaller than backlink counts, and why the referring domain count is the more honest number to manage against.
Root domain, subdomain and IP add further layers. Some tools count blog.example.com and example.com as separate referring domains and some do not. Referring IP addresses group domains sitting on the same server, which is occasionally useful for spotting a network and mostly noise.
Where this matters commercially: a proposal quoting a backlink count is quoting the flatterable number. Two hundred backlinks from eleven domains is an eleven-domain profile. Ask for referring domains, always, and ask whether subdomains were counted separately. We have reviewed profiles where correcting the counting method cut the headline figure by ninety percent without a single link changing.
Four words describing one piece of markup, and only three of them are real HTML.
| Term | What is in the HTML | What it signals | Typical source |
|---|---|---|---|
| Dofollow | Nothing. No rel attribute at all | A normal endorsement, eligible to pass ranking signals | Editorial mentions, genuine citations |
| Nofollow | rel="nofollow" | The publisher is not vouching for the destination | Older platform defaults, some publications, comments |
| Sponsored | rel="sponsored" | The link was paid for or is part of a commercial arrangement | Advertising, paid placements, affiliate links |
| UGC | rel="ugc" | The link came from user-generated content | Forum posts, comments, community profiles |
Dofollow is not a real attribute. There is no rel="dofollow". The word exists only as the opposite of nofollow, and a “dofollow link” simply means a link with no rel restriction on it. If somebody promises to supply rel="dofollow" links, they are describing normal links in jargon.
Nofollow stopped being an absolute instruction some years ago and is now treated as a hint, which means search engines may or may not take it into account. In practice this makes the dofollow versus nofollow distinction less binary than most reporting implies, and it makes the older habit of dismissing nofollow links outright a mistake.
Sponsored and ugc were introduced to give publishers a truthful way to mark commercial and community links. They are not penalties. Marking a paid link as sponsored is the compliant way to accept payment for a placement; leaving a paid link unmarked is the part that violates link spam policy.
Multiple values can appear together, such as rel="nofollow sponsored", and that is normal rather than a sign of anything. What matters for your reporting is that a tool’s follow and nofollow columns are describing markup, not describing quality.
The most-used and least-understood term in the glossary.
Link equity is the ranking value a link can pass from one page to another. Older writing calls it link juice, and PageRank is the original named algorithm behind the idea. The concept survives even though the public metric has not existed for over a decade.
It is a property of the linking page, not the linking site. A link from a deep, rarely-referenced page on a well-known domain passes less than a link from a page that is itself well referenced. This is why “we got you a link on a big site” can mean very little, and why the page matters more than the logo.
It divides, roughly. A page with four outbound links and a page with four hundred are not equivalent placements. You do not need to calculate this, but you should recognise it when you see a link sitting in a list of two hundred others.
Equity moves through your own site too, which is the part people forget. Internal links distribute whatever arrives at your best-referenced pages to the pages that need to rank, and a link that lands on a page with no internal path onward is largely wasted. That plumbing is part of what our technical SEO work handles.
What link equity is not: a currency you can buy, a number any tool can report for a single link, or a thing that flows through a redirect chain undiminished. Treat it as a directional idea that explains why placement matters, not as an accounting ledger.
Anchor text is the clickable words in the link. The type describes what those words are.
Exact match anchor uses your target phrase verbatim: “seo services singapore”. It is the strongest relevance signal and also the most obvious manipulation signal, which is why a profile with a high proportion of exact match anchors looks engineered.
Partial match anchor contains the phrase inside a natural sentence: “their guide to choosing an SEO agency in Singapore”. This is what genuine editorial linking mostly produces.
Branded anchor is your business or product name. In a healthy profile this is usually the single largest category, because that is how people refer to companies in writing.
Naked URL anchor is the address itself as the visible text. Common in citations, references, press releases and forum posts.
Generic anchor is “click here”, “this article”, “read more”. Unhelpful for relevance and completely normal in real content.
Image anchor is a linked image, where the alt text does the work the anchor text would otherwise do. If the alt attribute is empty, the link carries no textual signal at all, which is a genuinely common oversight on logo and badge links.
The distribution is the diagnostic, not any single anchor. Profiles built by real publishers skew heavily branded and partial. Profiles built to a target keyword skew exact, and the skew is visible in any tool’s anchor report. You generally cannot dictate anchor text to an editor, and attempting to is one of the faster ways to have a pitch declined.
Three origins, and the distinction determines both the value and the risk.
An editorial link is one somebody else chose to add while writing about something, without you asking or paying. These are the links the whole ranking signal is designed to reward and the hardest to get at volume.
A placed link is one you put there yourself through a legitimate route: a directory submission, a membership listing, a professional register, a supplier stockist form, a conference speaker profile, a social bio. Entirely legitimate, generally lower value, and finite. You will run out of them, which is the point at which most self-directed link programmes stall.
A paid link is one that exists because value changed hands, whether money, product, or a reciprocal placement arranged for search purposes. Unmarked, it violates link spam policy. Marked sponsored, it is an advertising placement that is perfectly acceptable and simply is not an SEO tactic.
An earned mention is a fourth category worth naming: somebody wrote about you without linking. Unlinked mentions are the highest-converting outreach target that exists, because the editorial decision has already been made.
Most agencies collapse these three origins into a single count when they report, which is why two profiles with identical numbers can be worth wildly different amounts. When you read a link report, the origin column is the one to read first. Businesses running small business SEO on a tight budget should expect the placed category to carry the first quarter and the editorial category to carry everything after it.
Four words, two axes, endless confusion.
Internal link: one page on your site to another page on your site. External link: a link between two different sites, in either direction.
Inbound link: pointing at you. Outbound link: pointing away from you. So an inbound external link is a backlink, and an outbound external link is you citing somebody else.
The mistake this causes in practice: a client is told internal links do not matter because “only backlinks count”, removes their internal linking discipline, and watches deep pages stop ranking. Internal links are the mechanism that gets any incoming authority to the pages that sell things, which is why internal structure is part of every ecommerce SEO build we do rather than an afterthought.
Outbound links are not a leak. The idea that linking out drains value is one of the most persistent pieces of bad advice in the field, and it produces pages that cite nothing, which reads to a human as unsourced.
Status words cause more client alarm than anything else in a link report, usually unnecessarily.
A live link is currently present on a currently reachable page. A lost link, in a database, means the crawler no longer found it on its last visit. Those are not the same claim: the page may have been temporarily unreachable, moved, paywalled or simply not recrawled.
So verify every lost link by opening the page before you act on it. In our experience a meaningful share of reported losses are recrawl artefacts rather than removals. The genuine losses divide into three causes: the page was deleted, the page was rewritten and your mention removed, or the link now points at a URL on your site that no longer resolves.
A broken backlink points at a 404 on your site, which is your problem to fix and the cheapest link work available. Redirect the old URL to the closest live equivalent and the link starts working again.
Reclamation is recovering a link you lost or never had: asking for a removed link back, fixing a broken target, or converting an unlinked mention.
Link velocity is the rate at which new referring domains arrive, and link decay is the natural rate at which old ones disappear as pages are retired. Both are descriptive. Neither is a threshold you can trip by being too successful, despite a long-running myth that a sudden increase looks suspicious.
The vocabulary here is almost entirely vendor vocabulary, and knowing that is the point.
Domain-level authority scores are third-party estimates, produced by individual tool vendors from their own crawl data on their own scale. They are not search engine signals and no search engine publishes an equivalent. They are useful for sorting a prospect list quickly and useless as a target.
“Toxic” and “spammy” are vendor classifications too, generated by pattern-matching rules, not by any search engine. A link flagged as toxic may be entirely harmless, and the flag should trigger a look, never an automatic action.
Disavow means telling a search engine to ignore specified links pointing at you. It is a narrow tool for a narrow situation, usually an actual manual action or a genuine history of paid or scheme links, and it is over-recommended by a wide margin.
Link profile simply means the whole collection of links pointing at you, described by shape rather than count: origin mix, anchor distribution, geographic spread, sector relevance, age spread.
Negative SEO describes somebody pointing bad links at your site deliberately. It is far rarer than the disavow-services market implies, and modern algorithmic handling ignores most of what it produces. The vocabulary of fear in this field sells services, and recognising which words came from a vendor rather than from a search engine is most of the defence. We make this distinction explicit in reporting for medical and clinic clients in particular, where compliance-minded owners tend to treat a toxicity flag as a legal problem rather than a vendor opinion.
A short note on Singapore specifically, because the terms land differently here.
The pool of relevant linking domains in Singapore is small. Fewer publications, fewer sector blogs, fewer independent review sites than a large market has. That means the distinction between referring domains and backlinks matters more, because a supplier with a site-wide link can inflate a count dramatically while the actual relationship base stays at a dozen.
It also raises the value of the placed category. Trade associations, professional registers, government-adjacent listings and local industry bodies are a larger share of a realistic Singapore profile than they would be elsewhere, and they are exactly the category that generic advice dismisses as low value.
And it makes volume offers look worse than they sound. If there are only sixty genuinely relevant domains in your sector locally, an offer of twenty links a month is not describing this market. Knowing the vocabulary is what lets you ask where the twenty are coming from. Our pricing page frames off-page scope in those terms rather than by link count.
In practice, the gap between the two counts is usually driven by a few sitewide placements. One supplier or partner site that carries your link in its footer or page template can account for most of the backlink total while counting as a single referring domain. Deduplicate to domains, sort them into self-placed listings, genuine sector references and broken links, and nothing about the site has changed; only the counting has, and the fix list writes itself.
Field notes: Our law firm case study describes its link work in plain, checkable terms rather than a headline count: contributed articles on two Singapore legal information platforms, editorial mentions in Singapore SME resource articles, and three directory submissions to Law Society-recognised directories, all editorially reviewed with no paid link placement. It also explains why source type matters, because legal-adjacent sources carry stronger relevance signals than general business links for competitive practice area terms. Over the 7-month programme, Domain Authority moved from 7 to 18, a vendor metric we treat as a direction of travel rather than a search engine signal. Using the right words, origin and relevance rather than raw count, is what makes a report like that readable and what stops a client paying for the wrong thing.
Getting the seo backlinks meaning straight is not pedantry, it is cost control. Every expensive mistake we see in off-page work traces back to a word: a count that measured the wrong object, a toxicity flag treated as a penalty, a nofollow link declined from a publication the client’s buyers actually read, a lost link chased that was never lost. Learn the five distinctions that carry real weight, which are link versus referring domain, markup versus quality, origin versus count, vendor metric versus search engine signal, and database status versus reality. With those five in hand you can read any report critically and ask the question that matters, which is always what the link is doing on the page rather than what it scores. If you want the full picture of what an engagement covers, the vocabulary above is the same one we report in.
It is also why our B2B ecommerce results write-up describes its link work by source, named trade directories and supplier registries, rather than by a link count.
We keep a version of this glossary on hand for client onboarding calls, because in our experience half of the friction in a first SEO conversation is two people using the same word to mean different things. Our team walks new clients through dofollow versus nofollow and referring domains versus total links in the first meeting specifically so later reports do not need a translation layer.
A backlink is one individual link on one page. A referring domain is one whole website that links to you at least once, however many links it sends. A single site with a footer link across two thousand pages gives you two thousand backlinks and one referring domain. Manage against referring domains, because that number reflects how many distinct publishers have actually referenced you and cannot be inflated by site-wide placements.
Not always, and the framing is too binary. Nofollow is now treated as a hint rather than an absolute instruction, and a nofollow link from a publication your customers read still delivers qualified traffic, brand recognition and a working relationship. A dofollow link from a site nobody reads delivers a markup state and little else. Judge the publisher and the page first, then look at the attribute.
It tells search engines the link exists because of a commercial arrangement, so it should not be treated as an editorial endorsement. It is not a punishment and it does not harm the page carrying it. It is the correct and compliant way for a publisher to accept payment for a placement, which is precisely why a paid link left unmarked is the problem rather than the payment itself.
Yes, as a relevance signal, but the useful unit is the distribution across your whole profile rather than any single anchor. Healthy profiles skew towards branded and partial match anchors because that is how real writers reference companies. A profile heavy with exact match commercial phrases looks constructed, and trying to dictate anchor text to an editor is a reliable way to have your pitch declined.
It is the ranking value a link can pass, and it belongs to the linking page rather than the linking site. A deep, rarely-referenced page on a famous domain passes less than a well-referenced page on a modest one, and a page stuffed with hundreds of outbound links splits whatever it has many ways. Treat it as a directional idea that explains why placement matters, not as a figure you can calculate.
Because “lost” in a backlink database means the crawler did not find it on its most recent visit, not that a publisher removed it. Temporary unreachability, a page move, a paywall or simply a slow recrawl all produce the same status. Always open the page before acting on a reported loss. A share of reported losses in every account we review turn out to be recrawl artefacts.
No. Every domain-level authority score is a third-party estimate built by one vendor from its own crawl, on its own scale, and no search engine publishes anything equivalent. They are genuinely useful for sorting a prospect list quickly and misleading as targets. Two tools will score the same site differently because they are measuring their own indexes, not a shared truth.
An editorial link is one somebody else chose to add while writing, without being asked. A placed link is one you added yourself through a legitimate route such as a directory, a membership listing, a register or a supplier form. Placed links are valid, cheaper and finite. Editorial links are slower and are what the ranking signal is designed to reward, so a mature profile needs both.
Almost never on a tool flag alone. Toxicity scores are vendor classifications produced by pattern rules, not search engine judgements, and the disavow file is a narrow instrument for a narrow situation such as an actual manual action or a genuine history of paid links. Unnecessary disavowing can remove links that were helping you. Investigate the flag, then usually do nothing.
No. A backlink is a link from a different site. Internal links are your own pages linking to each other, and they are a separate mechanism with a separate job, which is distributing whatever authority arrives at your best-referenced pages to the pages that need to rank and convert. Both matter. Neglecting internal links because “only backlinks count” is one of the more expensive misreadings of this vocabulary.
If you are holding a link report and cannot tell whether the numbers in it are good, that is a twenty-minute conversation rather than a project.
