Quick Answer: What is link?
A link is a reference that points from one place to another, and on the web it is a clickable element that takes a reader to another page, a file, or a spot further down the same page. In plain language, a link is a shortcut made of a target address and some text or an image you can click. You meet links in browser address bars, in search results, inside articles, in emails, and in app menus.
Not every link is the same. A hyperlink jumps you somewhere new, while a citation link simply points readers to a source, and a navigation link moves you around a single site. Some links open in a new tab, some stay in place, and some are hidden from search engines on purpose.
Before you trust or build a link, check where it actually points, whether the text describes the destination, if it opens safely, and whether it still works months later.
Why This One Small Word Causes So Much Confusion
Have you ever clicked something blue, landed somewhere completely unexpected, and wondered who decided that should happen? That is the everyday mystery of the link. It looks simple, a word you can click, yet the same term describes a chain link, a missing link in an argument, a link in a spreadsheet formula, and the thing your uncle sends you at midnight with the message “you have to see this.”
The confusion is not your fault. “Link” is one of those words that carries several jobs at once. In computing, it usually means a hyperlink, a reference inside a document that points to another document or to a location within one. That idea grew out of hypertext, a term coined around 1965 to describe text that could jump between connected pieces rather than being read in a straight line.
This article sticks mainly to the computing sense, because that is what most people mean when they search the word. It also touches on the broader idea of a link as a connection, since that meaning still shows up in publishing, science, and plain conversation. By the end, the word should feel less slippery and more like a tool you understand.
The Anatomy of a Link: Target, Text, and Behavior
Every web link has a few moving parts, and knowing them makes you harder to fool. The target is the address the link points to, usually a URL. The anchor text is the clickable words you see. The behavior is what happens when you click, such as opening in the same tab, a new tab, or jumping to a section.
Fragment identifiers deserve a special mention. A link that ends in something like `#section` points to an element with a matching id inside the same page. That is how a table of contents jumps you down to a heading without reloading anything. It is also why broken anchors happen: rename the heading and the link lands nowhere.
There is also a separate “ element that sits in a page’s head section. It declares relationships to outside resources such as stylesheets and icons. It is not clickable, and mixing it up with `` is a common beginner mistake.
The Different Types of Links You Meet Every Day
Not all links behave the same, and the differences matter when you are building a site or judging whether a source is trustworthy. Here is how the main types compare.
| Link type | What it does | Where you see it |
|---|---|---|
| Hyperlink | Jumps to another page or file | Articles, emails, search results |
| Anchor link | Scrolls to a section on the same page | Long guides, documentation |
| Navigation link | Moves you around one site | Menus, footers, breadcrumbs |
| Citation link | Points to a source or reference | Research papers, news stories |
| No-follow link | Tells search engines not to pass ranking credit | Comments, sponsored content |
| Deep link | Opens a specific screen inside an app | Mobile apps, marketing messages |
The no-follow attribute arrived in 2005 as a hint that a link should not pass ranking credit. It is a hint, not a command, which is why the topic still sparks arguments among site owners. If you have ever wondered why some links in blog comments seem to do nothing for the commenter, that attribute is usually the reason.
Deep links are worth a note too. They point not just to an app but to a particular screen inside it, which is why a restaurant link can open straight to its menu rather than its home page. When these break, users often land on a generic screen and assume the app is broken.
How Links Travel Beyond the Browser
Links are not confined to web pages. They also show up in the plumbing that moves data between servers. HTTP defines a `Link` header, standardized in RFC 8288 in October 2017, for expressing relationships between resources outside HTML. That header carries relation types like next, prev, and canonical, which help systems understand how pages relate to one another.
Those relation types live in a public registry maintained by IANA, the body that keeps internet naming and numbering records. If you have ever seen a website’s pagination work smoothly across many pages, relation types are often doing quiet work behind the scenes.
The broader sense of a link, meaning a connection, shows up in scholarly publishing too. A citation link ties a claim to its source, and persistent identifiers such as DOIs exist to keep those connections from rotting when pages move. That is the same problem web links face, just with a different solution.
If you want to see how link behavior plays out in a demanding real-world setting, remote gaming is a good test. Services like Parsec, Moonlight, and Steam Link live or die on how well a connection holds up, and a comparison of Parsec vs moonlight vs steam link for everyday gaming shows how much link quality shapes the experience. The same lesson applies to ordinary browsing: a link is only as good as the path behind it.
What Makes a Link Good or Bad in Practice
A working link and a good link are different things. A good link takes you where the words promised, loads quickly, and still exists next month. A bad link surprises you, wastes your time, or hides its real destination.
From hands-on experience, a few habits separate careful link builders from careless ones. The most common mistakes are vague anchor text like “click here,” links that open in new tabs without warning, and destinations that quietly change after a site redesign. Another frequent slip is linking to a page that has moved, so the reader hits a dead end and blames the messenger.
What actually works is dull but effective. Write anchor text that describes the destination, so the link makes sense when read aloud on its own. Test links after any site update. Keep the number of links in a paragraph modest so readers are not forced to choose. And when a link points to something that needs context, say so in the sentence around it.
Accessibility guidance backs this up. The WCAG 2.2 standard, published as a W3C Recommendation in October 2023, requires that a link’s purpose be determinable from its text or its surrounding context. That rule exists because screen reader users often pull up a list of links with no surrounding sentences. A page full of “read more” links is a maze for them.
Before you click a strange link, a little caution goes a long way. Learning how to check whether a link is safe is a basic skill now, and it is one worth practicing until it becomes automatic.
Links in Real Life: Networks, Backhaul, and Satellites
The word link also describes physical and wireless connections, and that usage is everywhere once you start noticing it. A wired backhaul link connects mesh wifi nodes with an ethernet cable, and when it fails, the whole network slows down in ways that feel mysterious. Understanding why a mesh wifi wired backhaul link stops working is a practical lesson in how a single broken link can degrade an entire system.
Satellite internet pushes the idea further. A satellite link carries data between a dish and a spacecraft, and policy decisions can sever it overnight. The story of how Starlink users in South Africa faced cutoff under a licensing rule shows that a link is not just technology; it is also regulation, contracts, and politics.
Direct-to-cell service takes the concept in another direction, turning satellites into something closer to cell towers in the sky. A look at how Starlink direct cell turned satellites into cell towers makes the point that a link is fundamentally about reach, not about wires.
Even the humble blog roll has a link story. The way a 1990s link log grew into a publishing powerhouse is a reminder that collecting and sharing links was itself a form of media long before social feeds existed.
Building and Sharing Links Without Making a Mess
If you run a site or write online, a few practical rules keep your links healthy. Start by choosing descriptive anchor text instead of generic phrases. Then decide deliberately whether a link should open in the same tab or a new one, and tell readers when it matters. After that, schedule a periodic check for broken destinations, since link rot is a matter of when, not if.
When you share links with other people, context is a kindness. A bare URL in a message forces the recipient to guess. A short sentence explaining what is on the other side saves everyone time and reduces the chance they skip it.
There is also a social side to linking well. Professionals who share useful links thoughtfully build trust faster than those who spray them everywhere. A guide on how to use LinkedIn well without wasting hours each week makes a similar point: quality beats volume, whether you are posting updates or passing along resources.
Finally, remember that a link is a promise. The words around it set an expectation, and the destination either keeps that promise or breaks it. Keeping the promise is most of the craft.
Conclusion
A link is a reference that connects one thing to another, and on the web it is a clickable pointer built from a target address and some anchor text. That simple definition hides real variety. Hyperlinks, anchor links, navigation links, citation links, and no-follow links all behave differently, and the same word stretches to cover ethernet backhaul, satellite connections, and scholarly citations.
The practical takeaway is straightforward. Write link text that describes where it goes. Check that destinations still work. Be cautious with links you did not create. And when you share one, add a sentence of context so the person on the other end knows what they are getting. Do those things and the humble link stops being a source of confusion and becomes what it was always meant to be: a reliable connection between two points.
Frequently Asked Questions
What is the difference between a link and a URL?
A URL is the address itself, the string that identifies where something lives. A link is the clickable wrapper around that address, usually made of anchor text plus the destination. You can have a URL without a link, such as one typed into an address bar, but a working hyperlink needs a URL underneath it.
Why do some links open in a new tab?
That behavior is set by the page’s code, not by your browser settings, though your browser can override it. Site owners often choose a new tab for outside destinations so readers do not lose their place. It can be helpful, but doing it without warning sometimes confuses people who expect to stay on the same page.
What does no-follow mean on a link?
It is an attribute that tells search engines the link should not pass ranking credit. It was introduced in 2005 and is treated as a hint rather than a strict command. You will see it on comment sections, sponsored placements, and user-generated content where a site cannot vouch for the destination.
Can a link point to a spot on the same page?
Yes. A link ending in a fragment, the part after the `#` symbol, scrolls to an element with a matching id on the same page. This is how in-page navigation works on long articles and documentation. If the target id changes or disappears, the link stops working even though the page still loads.
How can I tell if a link is trustworthy before clicking?
Look at where it actually points, not just the words you see. Hover over it to preview the destination, check whether the domain matches what you expect, and be wary of urgent messages pushing you to click. If something feels off, open a new tab and reach the site directly instead of following the link.
Do links ever stop working on their own?
They do, and the phenomenon is called link rot. Pages get deleted, domains expire, and sites reorganize their structure, leaving old links pointing at nothing. That is why periodic link checks matter for anyone who maintains a website, and why persistent identifiers exist for scholarly citations.
