Off-page SEO is the work of earning signals from outside a website that tell search engines the site deserves trust and authority. The main signals are backlinks, brand mentions, digital PR and reviews, none of which live on the site's own pages.
A page with weak off-page signals can still rank for an easy, low-competition term. It loses to a page backed by real authority once competition rises. Below is what each off-page signal does, how Google treats it, and where to start.
Off-page SEO covers backlinks, brand mentions, digital PR, social signals and E-E-A-T.
A backlink's value depends on the linking site's relevance and trust, not link count alone.
Domain Authority is Moz's own 1-to-100 score, not a Google ranking factor.
rel="sponsored" and rel="ugc" tell Google which links are paid or user-generated.
What Is Off-Page SEO?
Off-page SEO is the set of actions taken away from a website's own pages to build its trust and authority with search engines. It includes backlinks, brand mentions, digital PR, guest posting, reviews and social signals. It decides how much Google trusts a site once the on-page content is already solid.
Off-page SEO is one of the three branches search engine optimization work splits into, alongside on-page SEO and technical SEO. On-page SEO and technical SEO shape what happens on a site's own pages and servers; off-page SEO happens everywhere else on the web.
Demand for the term reflects a straightforward split. The keyword "off page seo" gets searched about 3,000 times a month in the US. That is more than four times the volume for "what is off page seo," at roughly 700 (Ahrefs).
| Number | What it means | Source |
|---|---|---|
| 3,000/month | US searches for "off page seo" | Ahrefs |
| 1 to 100 | Domain Authority score range (Moz's own metric) | Moz |
| 2014 | Year Google introduced E-A-T in its Rater Guidelines | Victorious |
| 2022 | Year Google added the second E, for Experience | Victorious |
| 2015 | Year Google's John Mueller said social signals are not a ranking factor | Semrush |
| sponsored / ugc | rel attributes Google recommends for paid and user-generated links | Google Search Central |
How Does Link Building Earn Backlinks?
Link building is the practice of earning links from other websites that point back to a site. Search engines read those links as a vote of trust. Wikipedia defines it as "efforts to increase the number of high-quality links pointing to a website."
A link earned through original research, a quote in a journalist's story, or a genuinely useful resource counts as an editorial link. That is the strongest type Google recognizes. A link bought, swapped or stuffed into a comment section carries far less weight. A large-scale link scheme risks a manual action, the kind of penalty Google has issued against manipulative links since the Penguin update in April 2012.
What Makes a Backlink High Quality?
A high-quality backlink comes from a site that is relevant to the topic and trusted in its own right. It is not part of a paid or reciprocal link scheme. One link from a respected, topically relevant site outweighs dozens of links from low-quality directories or link farms.
Moz scores a site's overall link profile from 1 to 100 as Domain Authority. A single link from a site near the top of that range typically counts for more than dozens of links from sites near the bottom. Relevance matters as much as trust: a backlink from a competitor's own industry carries more weight than one from an unrelated niche.
What Is Domain Authority?
Moz built Domain Authority (DA) as its own 1-to-100 scale for comparing a site's likely ranking strength against competitors in the same space. The score lives entirely inside Moz's own tools. Google has never confirmed running anything like it internally, and treats it as an outside, third-party number (Moz).
Other tools publish their own version of the same idea under different names, such as Ahrefs Domain Rating and Semrush Authority Score. Each is built from that tool's own backlink index. The scores disagree with each other because each company crawls a different slice of the web. A relative trend over time matters more than the exact number.
How Do Nofollow, Sponsored and UGC Links Differ?
A plain link passes trust signals to the page it points to by default. The rel="nofollow" attribute tells Google to weigh a link less heavily. Google added rel="sponsored" and rel="ugc" in September 2019, so publishers can label paid links and user-generated links separately (Google Search Central).
Google still crawls and may follow a nofollow, sponsored or ugc link as a hint. The attribute only asks Google to treat the link as less trustworthy, not to ignore it. Removing the tag from a long-time trusted contributor's link is one way site owners reward consistent, high-quality contributions.
Does Digital PR Help SEO?
Digital PR is the practice of pitching journalists, bloggers and publications original data, research or a newsworthy story in exchange for coverage and a link. It earns the editorial links Google weighs most heavily. The linking site chose to cite the story on its own judgment, not because anyone paid for the placement.
Digital PR traces back to journalist-request services such as HARO, launched in 2008. These connect reporters hunting for a story with a source willing to provide data or a quote. A pitch built around an original number a journalist can cite outperforms a generic press release. The output is an editorial link instead of a paid placement.
Do Social Signals Affect Rankings?
No, not directly. Google's John Mueller stated in 2015 that social signals are not a ranking factor, a claim Google has not reversed since (Semrush). Likes, shares and comments do not move a page up the results on their own, even when a post goes viral.
Social posts still help indirectly. They put a new page in front of people who go on to link to it, cite it, or search for the brand by name. Branded search volume is itself a signal Google tracks as a sign of a brand's real-world recognition.
How Does E-E-A-T Connect to Off-Page SEO?
E-E-A-T stands for Experience, Expertise, Authoritativeness and Trustworthiness, the framework Google's human quality raters use to judge content. Google introduced E-A-T in its Search Quality Rater Guidelines in 2014 and added the second E, for Experience, in 2022 (Victorious). Off-page signals, such as who else talks about a brand, feed directly into the trust and authoritativeness Google's raters assess.
A brand with no outside coverage, no reviews and no mentions beyond its own website has thin authoritativeness no matter how well the page reads. Off-page signals are the evidence a search engine and a human rater both use to judge whether a claim of expertise holds up.
When Do You Disavow a Backlink?
Disavowing a backlink tells Google to ignore it when calculating a site's ranking signals. Google Search Console Help calls it an advanced feature most sites never need. Google states plainly that it can usually assess which links to trust without extra guidance (Google Search Console Help).
A disavow file makes sense after a manual action for unnatural links, or after a negative-SEO attack with 100 or more spammy links appearing overnight. Most sites never see either situation, since Google's own systems already discount low-quality links before they can do damage.
What Belongs on an Off-Page SEO Checklist?
An off-page SEO checklist tracks backlinks earned, source quality, anchor text variety, brand mentions and review volume in one place. It usually runs alongside a backlink-tracking tool such as Ahrefs or Moz Link Explorer. It also covers two tactics worth a specific plan: broken link building and anchor text balance.
Anchor text: vary branded, naked-URL and partial-match anchors, so no single phrase dominates a site's backlink profile.
Guest posting: write for sites with a genuinely relevant audience, not a directory of any site that accepts a post for a fee.
Broken link building: find a dead (HTTP 404) page on another site, then offer a working replacement of your own as the fix.
Unlinked brand mentions: search the brand name without a link, then ask for one; a mention is already most of the work.
Reviews: Google Business Profile and industry-specific review sites feed the trust signal E-E-A-T and local pack rankings both use.
Off-Page SEO FAQ
What is off-page SEO in simple terms?
Off-page SEO is the work of earning trust and authority signals from outside a website, mainly backlinks, brand mentions, reviews and digital PR.
How is off-page SEO different from on-page SEO?
Off-page SEO builds trust and authority from outside a website. On-page SEO optimizes a page's own content and HTML elements, such as titles and headings.
Is Domain Authority a Google ranking factor?
No. Domain Authority is Moz's own 1-to-100 score. Google does not use it and has never confirmed any internal score like it.
Do social shares help a page rank?
Not directly. Google's John Mueller said in 2015 that social signals are not a ranking factor, though social posts can bring links and branded searches indirectly.
What is the difference between nofollow, sponsored and ugc links?
Nofollow is a general signal to weigh a link less heavily. Sponsored marks paid links, and ugc marks user-generated content, such as comments and forum posts.
When do you need to disavow a backlink?
After a manual action for unnatural links, or a clear negative-SEO attack with a sudden flood of spammy links. Most sites never need the tool at all.
The Bottom Line
Off-page SEO is the trust layer search engines check once a site's on-page content and technical foundation are already solid. Earn links through original research, digital PR and genuine expertise instead of buying or swapping them. Keep Domain Authority and Ahrefs Domain Rating as a rough trend, not a target. Our link building services focus on editorial links from relevant, trusted sites instead of volume for its own sake.
