Link Building Terms

Link Building Terms: Important Definitions Every Business Should Know

Link building is one of the most discussed parts of SEO, but it is also one of the most misunderstood.

In simple terms, link building is the process of earning links from other websites to your own website. These links are called backlinks, and they can help search engines understand that your website is trustworthy, useful, and worth ranking.

But link building is not about collecting as many links as possible. That old approach can actually harm a website if the links are low-quality, spammy, or irrelevant.

Modern link building is about quality, relevance, authority, and trust.

For businesses, understanding link building terms is important because backlinks often appear in SEO reports, audits, competitor analysis, and outreach strategies. If you know what these terms mean, it becomes much easier to understand whether a link building strategy is actually helping your website or putting it at risk.

This glossary explains the most important link building terms in plain English.

Backlink

A backlink is a link from another website to your website.

For example, if an industry blog writes about your business and links to your service page, that link is a backlink.

Backlinks are important because search engines often treat them as signals of trust and authority. If reputable websites link to your content, it can help improve your website’s ability to rank.

However, not all backlinks are equal. A link from a relevant, trusted website is far more valuable than hundreds of links from spammy or unrelated websites.

Inbound Link

An inbound link is another name for a backlink.

It means a link coming into your website from another website.

For example, if a marketing publication links to your SEO guide, that is an inbound link.

Inbound links can help improve authority, referral traffic, and brand visibility when they come from quality sources.

Outbound Link

An outbound link is a link from your website to another website.

For example, if your blog links to Google Search Console documentation, that is an outbound link.

Outbound links can be useful when they help users access trusted sources or supporting information. They should be relevant and natural, not added randomly.

Internal Link

An internal link is a link from one page on your website to another page on the same website.

For example, a blog post about technical SEO may link to your technical SEO audit service page.

Internal links are not backlinks, but they are still important for SEO. They help users navigate your website and help search engines understand the relationship between your pages.

Referring Domain

A referring domain is a unique website that links to your website.

For example, if one website links to you five times, that still counts as one referring domain.

Referring domains are important because search engines often value links from multiple trusted websites. A website with links from 50 relevant referring domains usually has a stronger backlink profile than a website with 500 links from only one domain.

Link Profile

A link profile is the overall collection of backlinks pointing to a website.

It includes the number of backlinks, referring domains, link quality, anchor text, link relevance, follow/nofollow status, and the types of websites linking to you.

A healthy link profile usually includes links from relevant, trustworthy, and diverse sources.

A poor link profile may include spammy links, irrelevant websites, over-optimised anchor text, or links from link farms.

Domain Authority

Domain Authority, often shortened to DA, is a third-party metric that estimates how strong a website may be in search engines.

It was created by Moz and is not an official Google metric.

DA can be useful for quick comparisons, but it should not be treated as a perfect measure of SEO value. A website with lower DA but strong relevance can sometimes be more valuable than a high-DA website with no topical connection.

Domain Rating

Domain Rating, often shortened to DR, is a metric from Ahrefs that estimates the strength of a website’s backlink profile.

Like DA, DR is not a Google metric. It is useful for analysing link strength, but it should not be the only factor when judging a backlink.

A relevant link from a real industry website can be more useful than a high-DR link from an unrelated or low-quality site.

Page Authority

Page Authority refers to the estimated strength of an individual page rather than the whole domain.

A website may have strong overall authority, but not every page on that website has equal value.

For example, a backlink from a popular article that already has links and traffic may be more valuable than a link from a hidden page that no one visits.

Link Equity

Link equity, sometimes called “link juice,” refers to the SEO value passed from one page to another through a link.

When a trusted page links to your website, some authority may pass through that link.

The amount of link equity depends on factors such as the linking page’s authority, relevance, number of outbound links, and whether the link is follow or nofollow.

Anchor Text

Anchor text is the clickable text used in a link.

For example, in the phrase “learn more about technical SEO audits,” the clickable words “technical SEO audits” are the anchor text.

Anchor text helps users and search engines understand what the linked page is about.

Natural anchor text is important. If too many backlinks use the exact same keyword-rich anchor text, it can look manipulative.

Exact Match Anchor Text

Exact match anchor text uses the exact keyword a page is trying to rank for.

For example, if a page targets “SEO consultant UK,” and another website links using the anchor text “SEO consultant UK,” that is exact match anchor text.

Some exact match anchors are normal, but too many can look unnatural.

A healthy backlink profile usually includes a mix of branded, natural, partial match, and generic anchors.

Partial Match Anchor Text

Partial match anchor text includes part of the target keyword but not the exact phrase.

For example, “SEO consultant for small businesses” could be a partial match anchor for a page targeting “SEO consultant UK.”

Partial match anchors often look more natural than repeated exact match anchors.

Branded Anchor Text

Branded anchor text uses a brand name as the clickable link.

For example, “Muhammad SEO” would be branded anchor text.

Branded anchors are usually natural and safe because people often link to businesses using their brand name.

A healthy backlink profile often includes a good amount of branded anchor text.

Naked URL

A naked URL is when the full URL itself is used as the clickable link.

For example:

https://example.com/seo-consulting/

Naked URLs are common in citations, directories, forums, and references. They are usually natural when used appropriately.

Generic Anchor Text

Generic anchor text uses non-specific words such as “click here,” “read more,” or “visit website.”

Generic anchors are not very descriptive, but they are common and natural in a balanced backlink profile.

For SEO, descriptive anchor text is usually more helpful, but generic anchors are not automatically bad.

Dofollow Link

A dofollow link is a normal link that can pass SEO value from one page to another.

Technically, there is no special “dofollow” tag. A link is considered dofollow when it does not have attributes telling search engines not to pass authority.

Dofollow links from relevant, trusted websites can help improve organic visibility.

Nofollow Link

A nofollow link includes an attribute that tells search engines not to pass normal ranking value through the link.

Nofollow links are commonly used for paid links, user-generated content, comments, and situations where the linking website does not want to endorse the target page.

Nofollow links may not pass the same SEO value as dofollow links, but they can still bring referral traffic, brand visibility, and a natural link profile.

UGC Link

UGC stands for user-generated content.

A UGC link uses the rel="ugc" attribute and is commonly used for links placed in comments, forums, reviews, or community-generated content.

This helps search engines understand that the link was added by users rather than the website owner.

Natural Link

A natural link is a backlink earned without direct payment, manipulation, or artificial link schemes.

For example, if a journalist, blogger, or industry website links to your content because they genuinely found it useful, that is a natural link.

Natural links are usually the safest and most valuable type of backlink.

Editorial Link

An editorial link is a link placed naturally within content by an editor, writer, or publisher.

For example, if a marketing publication references your SEO research in an article and links to your website, that is an editorial link.

Editorial links are valuable because they usually come from genuine content and are given because the page adds value.

Contextual Link

A contextual link is a link placed within the main body content of a page.

For example, a sentence inside an article linking to your guide is a contextual link.

Contextual links are often more valuable than links placed in footers, sidebars, or author bios because they appear within relevant content.

Sitewide Link

A sitewide link appears across many or all pages of a website.

Examples include footer links, sidebar links, or navigation links.

Sitewide links are not always bad, but they can look unnatural if used purely for SEO manipulation.

For example, a web design company linking to itself in every client footer may create sitewide backlinks. These should be handled carefully.

Footer Link

A footer link is a link placed in the bottom section of a website.

Footer links are common for navigation, policies, credits, and partner links.

From an SEO perspective, footer links are usually less valuable than relevant contextual links. If used excessively or unnaturally, they can create risk.

Link Relevance

Link relevance refers to how closely related the linking website or page is to your website.

For example, a backlink from a marketing blog to an SEO consultant’s website is relevant. A backlink from an unrelated gambling or random coupon site would not be relevant.

Relevance is one of the most important factors in link quality.

A smaller relevant website can sometimes provide a better link than a large unrelated website.

Link Quality

Link quality refers to how valuable, trustworthy, and relevant a backlink is.

A high-quality backlink usually comes from a real website with genuine traffic, relevant content, editorial standards, and a clean reputation.

A low-quality backlink may come from spam sites, link farms, private blog networks, or irrelevant directories.

Quality matters far more than quantity in modern link building.

Link Quantity

Link quantity refers to the number of backlinks pointing to a website.

While quantity can matter, it should never be the main goal.

A website with 20 strong, relevant backlinks can often be in a better position than a website with 2,000 spammy links.

Link building should focus on earning the right links, not just more links.

Toxic Backlink

A toxic backlink is a low-quality or spammy link that may create SEO risk.

These links often come from link farms, hacked websites, spam directories, adult sites, gambling sites, or unrelated low-quality domains.

Not every strange backlink is dangerous, but a large number of toxic backlinks can make a link profile look unnatural.

Businesses should monitor their backlink profile regularly, especially if they notice sudden spikes in suspicious links.

Spammy Backlink

A spammy backlink is a backlink from a low-quality, irrelevant, or suspicious website.

Spammy backlinks may be automatically generated, bought in bulk, or created through manipulative SEO tactics.

Examples include links from fake blogs, scraped content websites, low-quality directories, or websites created only to sell links.

Spammy backlinks usually provide little or no real SEO value.

Link Farm

A link farm is a group of websites created mainly to link to other websites and manipulate rankings.

These websites usually have poor content, unnatural linking patterns, and little real audience.

Links from link farms are risky and should be avoided.

Google’s systems are much better at detecting these patterns than they used to be.

Private Blog Network

A private blog network, often shortened to PBN, is a network of websites created or controlled to build backlinks artificially.

PBN links may sometimes produce short-term ranking movement, but they carry serious long-term risk.

If Google detects a PBN, the linked website may lose rankings or receive a manual action.

For sustainable SEO, PBNs should be avoided.

Disavow File

A disavow file is a file submitted to Google to tell it that you do not want certain backlinks considered when evaluating your website.

It is usually used when a website has a large number of spammy, artificial, or harmful backlinks.

The disavow tool should be used carefully. Disavowing the wrong links can remove useful signals.

For most websites, disavow is only needed when there is a clear pattern of unnatural or toxic links.

Google Disavow Tool

The Google Disavow Tool allows website owners to submit a list of backlinks or domains they want Google to ignore.

It is mainly used for serious backlink issues, such as spam attacks, past link schemes, or large numbers of manipulative links.

Businesses should not panic over every spammy link. But if suspicious backlinks appear at scale, especially from PBNs or link farms, a careful disavow process may be appropriate.

Manual Action

A manual action happens when Google’s human reviewers determine that a website has violated Google’s spam policies.

For link building, manual actions can happen because of unnatural links, paid links, link schemes, or manipulative backlink practices.

If a website receives a manual action, it may lose rankings until the issue is fixed and a reconsideration request is submitted.

Link Scheme

A link scheme is any attempt to manipulate search rankings through unnatural links.

Examples include buying links that pass ranking value, excessive link exchanges, automated link building, PBNs, and large-scale low-quality guest posting.

Link schemes are risky because they violate Google’s guidelines.

Sustainable link building should focus on earning links through value, relevance, and genuine relationships.

Guest Posting

Guest posting means writing content for another website, usually with a link back to your own website.

When done properly, guest posting can build authority, referral traffic, and brand visibility.

The key is relevance and quality. A guest post on a respected industry website is very different from mass guest posting on low-quality sites created only for backlinks.

Guest posting should be used as a brand and authority strategy, not just a link shortcut.

Digital PR

Digital PR is the process of earning online coverage, mentions, and backlinks through newsworthy content, stories, data, or expert insights.

For example, a business may publish original research that journalists and industry websites reference.

Digital PR can generate high-quality backlinks from trusted publications while also improving brand awareness.

It is one of the strongest white-hat link building methods when done well.

Linkable Asset

A linkable asset is a piece of content created specifically to attract backlinks.

Examples include original research, statistics pages, calculators, tools, templates, industry reports, infographics, and comprehensive guides.

People are more likely to link to content that provides unique value.

A strong linkable asset gives other websites a reason to reference your page naturally.

Resource Page Link Building

Resource page link building involves getting your website listed on pages that curate useful resources.

For example, a university, industry website, or organisation may have a page listing helpful marketing resources.

If your content is genuinely useful and relevant, you may be able to earn a link from such pages.

Broken Link Building

Broken link building is a strategy where you find broken links on other websites and suggest your relevant content as a replacement.

For example, if a website links to an outdated SEO guide that no longer exists, you can contact them and suggest your updated guide instead.

This approach works best when your replacement content is genuinely useful and relevant.

Outreach

Outreach is the process of contacting website owners, journalists, bloggers, editors, or businesses to build relationships and earn links.

Good outreach is personalised, relevant, and value-driven.

Poor outreach is usually generic, spammy, and focused only on asking for backlinks.

Effective outreach should explain why your content is useful for their audience.

Link Prospect

A link prospect is a website or person that may be a good opportunity for earning a backlink.

For example, an industry blog, journalist, partner website, directory, or resource page could be a link prospect.

Good link prospects are relevant, trustworthy, and likely to benefit from referencing your content.

Link Insert

A link insert is when a backlink is added into existing content on another website.

This can be legitimate if the link genuinely improves the content and is editorially placed.

However, paid link inserts are often risky if they are used to manipulate rankings and are not properly marked.

Businesses should be careful with link insert offers because many are low-quality or against Google’s guidelines.

Reciprocal Link

A reciprocal link happens when two websites link to each other.

Some reciprocal linking is natural. For example, partners, suppliers, or collaborators may link to each other.

However, excessive link exchanges done purely for SEO can become risky.

The key question is whether the link makes sense for users.

Link Exchange

A link exchange is an arrangement where websites agree to link to each other.

Small, natural link exchanges are common. But large-scale or manipulative link exchanges can violate search engine guidelines.

If the only reason for the link is to manipulate rankings, it is not a good long-term strategy.

Citation

A citation is a mention of a business’s name, address, phone number, or website on another site.

Citations are especially important in local SEO.

For example, a business listing on a local directory or industry directory can act as a citation.

Citations help confirm business information and can support local search visibility.

Unlinked Brand Mention

An unlinked brand mention happens when another website mentions your business name but does not link to your website.

For example, a blog may mention “Muhammad SEO” without linking to the site.

Unlinked brand mentions can sometimes be converted into backlinks by contacting the website and politely asking them to add a link.

Link Velocity

Link velocity refers to the speed at which a website gains backlinks.

A natural increase in backlinks is usually fine, especially after PR, content promotion, or brand growth.

But sudden spikes from low-quality or unrelated websites can look suspicious.

Link velocity should be evaluated alongside link quality and relevance.

Referring Page

A referring page is the specific page that links to your website.

For example, if a blog article links to your SEO guide, that blog article is the referring page.

When evaluating backlinks, the referring page matters because a link from a relevant article is usually more useful than a link from an unrelated page.

Final Thoughts

Link building is not about chasing random backlinks. It is about building trust, authority, and relevance across the web.

A strong backlink profile can help improve organic visibility, but poor link building can create long-term SEO risk.

For businesses, the safest approach is to focus on quality over quantity. Relevant editorial links, digital PR, useful content, guest posting on trusted sites, and natural brand mentions are far more valuable than spammy shortcuts.

Understanding these link building terms will help you review backlink reports, evaluate SEO recommendations, and avoid risky tactics.

Good link building should support your brand, your users, and your long-term search visibility — not just your rankings.
