Types of backlinks: which ones carry weight

A backlink’s type tells you three things: who decided to place it, where it sits on the page, and which attribute it carries. Those three facts predict most of its value. A link that an editor chose to add inside the body of a relevant article sits at the top. A link that anyone can create for themselves, or that repeats in a template across a whole site, sits at the bottom.

The names used below are all defined in the glossary.

Three ways to sort a backlink

By who placed it. Editorial links are given by someone with a free choice. Self-created links (profiles, comments, most directories) involve no choice by anyone else. Paid and negotiated links sit in between.

By where it sits. In-content links sit in the main text. Sitewide links sit in a footer, sidebar or template. Image links wrap a picture, not words.

By attribute. A link is either followed (no attribute) or qualified with nofollow, sponsored or ugc.

The main types compared

Risk uses this site’s R1 to R5 scale, where R1 is within Google’s guidelines and R5 is severe. The weight column gives a direction only. The research has no measured weight for any link type.

Type	How you get it	Usual attribute	Likely weight	Risk
Editorial (earned, digital PR)	A writer cites your data, story or expert	Followed or nofollow, the publisher decides	Highest	R1
Genuine guest post	You write for a publication with editorial standards	Often followed	High when the site is real	R1 to R2
Paid guest post	You pay a publisher to run an article	Followed without a label in trade use	Depends wholly on the site	R3
Niche edit (link insertion)	A link is added to an existing article	Usually followed	Depends on the host page	R3
Directory and local citation	You submit a listing	Mixed	Low as a ranking link	R1 curated, R3 for bulk packages
User-generated (forum, comment, profile)	You post it yourself	Mostly nofollow or ugc	Very low	R1 for real participation, R3 or more for spam
Sponsorship	You fund an event, club or project	Should be sponsored	Low to medium	R2
Sitewide (footer, sidebar)	Template placement	Mixed	Low per link	R3, higher with exact-match anchors
Image link	Your image is used with a credit	Followed or nofollow	Similar to a text link in the same position	R1
Redirect (301)	An old URL or domain points to yours	Not applicable	High if relevant, nothing if not	R2 for a real merger, R4 for unrelated domains
Widget or badge	Embed code carries a link	Should be nofollow	Low	R3 to R4 with keyword anchors
Network link (PBN, automated)	Bought or built on controlled sites	Followed	Unreliable	R4 to R5

Followed, nofollow, sponsored and ugc

A followed link is a plain link. The other three are qualifiers a publisher adds. Google’s guidance says sponsored is for paid placements, ugc is for forums and comments, and nofollow is for links a site does not want to vouch for. Since 2019 Google is reported to treat all three as hints, so it may still choose to use a qualified link.

Nobody outside Google knows how often it does. In Ahrefs’ study of one million keywords, published in January 2025, followed referring domains correlated with rankings at 0.250 and all referring domains at 0.255. Those two numbers are too close to tell the types apart. In a March 2026 survey of 518 SEOs by Editorial.link, 78.8% said they believe nofollow links affect rankings. That is a belief, not a measurement.

Two details matter when you buy. An Ahrefs study is reported to have found the sponsored attribute on about 0.01% of referring domains, so most paid links carry no label. And the best publishers often refuse to sell followed links at all: ESBO’s September 2026 analysis of 16,625 publishers, reported by Entrepreneur, found 39% of publishers at DR 80 or more sell nofollow placements only. Our lesson on link attributes covers the detail.

Types by who placed the link

Editorial links. The link exists because the page is better with it. Most are the result of deliberate promotion, which is what digital PR is. News coverage is often copied to partner sites, and the value of those syndicated copies is disputed: a single-site test by Reboot Online in February 2025 saw rankings rise after about 180 syndicated links, while BuzzStream’s guide treats such copies as worth little for SEO.

Guest posts. A genuine guest post is written for a publication that rejects weak pitches. A paid guest post is an article a publisher runs for a fee. They look alike and behave differently. BuzzStream’s June 2026 study of roughly 257,000 sellers rated 96.2% as low quality and found 39.6% had no organic traffic.

Niche edits. A link added to an article that is already indexed. The value comes from the host page’s own links and traffic, not the domain’s score. BuzzStream’s August 2026 study rated 97.5% of link insertion offers as low quality. See niche edits for how to judge one.

Directories and citations. A citation lists a business name, address and phone number. Practitioners treat local citations as a local pack and entity signal more than a ranking link. BrightLocal’s price in October 2026 was $2.00 to $3.20 per citation. Curated directories pass a simple test: would a customer use it, and does it reject listings?

User-generated links. Forum posts, comments, profiles and Q&A answers. Most are nofollow or ugc, and all external links on Wikipedia are nofollow. Practitioners value them for visibility and referral traffic. Forum comments with optimised links are named in Google’s spam policies.

Sponsorships. A sponsor page linking to a funder is a paid link in the strict sense, and Google expects a qualifying attribute. Genuine sponsorships are ordinary business activity and sit at R2 on our scale.

Types by where the link sits

In-content links. A Google patent known as the reasonable surfer model is reported to describe links on one page passing different amounts of value depending on position, font size and how likely a reader is to click. Links in the main body come out ahead of links in boilerplate.

Sitewide links. A footer link on 5,000 pages is still one referring domain. Ahrefs’ 2025 study found referring domains correlate with rankings slightly better than raw backlink counts, 0.255 against 0.248. The leaked Google documentation from 2024 contains a field for repeated links from the same source to the same target, which analysts read as diminishing returns. That reading is an inference.

Image links. When an image is the link, Google’s link guidance is reported to use the alt text as the anchor text.

Redirects. Google’s Gary Illyes is reported to have said in 2016 that 301 redirects no longer lose PageRank. The condition is relevance. Google staff have said for years, in statements reported by the trade press, that redirects to unrelated pages can be treated as soft 404s and pass nothing. Buying dropped domains to exploit their links has been a named spam policy, expired domain abuse, since March 2024. Expired domains and 301s explains the legitimate and the risky versions.

Which types carry weight

The evidence supports four rules, in direction if not in size.

1. Editorial choice beats self-placement. Google’s spam policies define link spam by intent to manipulate rankings, and every type it lists is one where nobody made an editorial choice.
2. The page matters more than the label. The 2024 leak documents a quality bucket on each anchor tied to the index tier of the linking page. Its weight is unknown.
3. Relevance matters. Analysts infer this from several leaked fields and from consistent Google guidance.
4. New referring domains beat repeat links from the same site.

So a nofollow link in a national newspaper can be worth more to a business than a followed link on a site nobody reads. For any paid type, vetting the publisher decides the outcome far more than the name on the invoice.
