Off-page SEO is the part of that happens away from your own website — the backlinks, brand mentions, press coverage, and reputation signals that other sites and platforms generate about you, rather than anything you write or fix on your own pages. Where on-page SEO is about what a page says and technical SEO is about whether a search engine can access and read it, off-page SEO is about whether the rest of the web treats your site as credible enough to be worth ranking.
That distinction is the whole definition. You can write strong content and keep a technically clean site and still struggle to rank, because search engines don’t take your word for your own authority — they look for outside evidence: other sites linking to you, people talking about your brand, directories and platforms listing you consistently. Off-page SEO is the work, and often just the ordinary business activity, that generates that outside evidence.
What Counts as Off-Page SEO?
“Off-page SEO” covers more ground than most people expect — it isn’t only link building. The main categories:
Backlinks. Links from other websites pointing to yours — the original and still the most studied off-page signal. Covered in depth in What Are Backlinks in SEO?
Link building. The deliberate practice of earning those backlinks — outreach, contributed content, digital PR pitches, and similar tactics aimed at getting other sites to link to yours on purpose. See What Is Link Building in SEO? for how that process actually works.
Brand mentions. Being named or discussed on other sites, whether or not the mention includes a link back to you.
Citations and directory listings. Your business name, address, and phone number appearing consistently across directories, maps platforms, and industry listings — most relevant to local businesses.
Reviews and reputation signals. Ratings and reviews on platforms like Google Business Profile, industry directories, and review sites.
Social signals. Shares, follows, and mentions on social platforms — a weaker, more indirect signal than the others, covered below.
Some of these you can actively pursue. Others — a customer mentioning you in a forum thread, a journalist citing your data — happen because of work you did elsewhere and simply get picked up. Off-page SEO includes both the deliberate and the incidental.
Backlinks and Link Building: The Core Off-Page Work
Most off-page effort, in practice, comes down to backlinks and the work of earning them. A backlink functions as a vote of confidence: an outside site choosing to point at your page, which search engines read as evidence that the content is worth pointing to. What makes a specific backlink more or less valuable — , referring domains, dofollow versus nofollow — is its own subject; see What Are Backlinks in SEO? for the full breakdown.
Link building is what generates those backlinks on purpose instead of waiting for them to happen. It covers a range of tactics — outreach to other site owners, guest content, digital PR, expert-quote contributions, resource-page pitches — all aimed at giving another site a genuine reason to link to yours. What Is Link Building in SEO? covers the specific tactics, and how to run them without drifting into the kind of manipulative link schemes Google has targeted with past algorithm updates.
The relationship between the three terms is straightforward once you see it laid out: backlinks are the asset, link building is the deliberate work of earning that asset, and off-page SEO is the broader category both sit inside, alongside everything else happening around your brand away from your own site.
Brand Mentions, Social Signals, and Other Unlinked Sources
Not every reference to your brand includes a link, and this is where off-page SEO gets less precise than counting backlinks.
Unlinked brand mentions. Some SEO practitioners believe search engines can extract some signal from a brand name appearing near relevant topics, even without a hyperlink attached — the idea being that consistently being talked about in the right contexts is itself evidence of relevance. Worth flagging: this isn’t something Google has confirmed as a deliberate, direct ranking input the way backlinks are, so it’s more reasonable to treat it as a byproduct of good off-page work than a tactic to chase on its own.
Social media. Links shared on most social platforms are generally nofollow and don’t pass the kind of direct ranking credit a backlink does. Where social helps is indirectly — content that gets shared and seen by more people has more chances to be noticed by someone who does link to it, or by a journalist looking for a source. Social is distribution that can lead to off-page signals, not an off-page signal by itself.
Digital PR. Coverage in industry publications or general press — someone writing about your business, your data, or your product because it was genuinely newsworthy — usually produces both a mention and, often, a link. It tends to be one of the more durable forms of off-page work, since the coverage exists independent of whether you keep paying for anything.
Off-Page SEO for Local Businesses
For a business with a physical location or a defined service area, off-page SEO adds a local layer on top of everything above:
consistency. Your business name, address, and phone number should match, exactly, everywhere they appear — your website, Google Business Profile, directories, social profiles. Inconsistent NAP details are a commonly cited source of local ranking confusion.
Directory and listings. Being listed accurately in relevant, legitimate directories functions as both a citation and, often, a genuine backlink. Low-quality directories built purely to house links add little.
Reviews. The volume, recency, and tone of a business’s reviews — and whether it responds to them — are the aspects most commonly discussed as part of local reputation signals, on top of the more obvious effect reviews have on whether a potential customer picks up the phone at all.
Local off-page work and general off-page work overlap heavily. A local business still benefits from the backlinks and mentions covered above; it just adds a citation and review layer on top.
How Off-Page SEO Fits With On-Page and Technical SEO
SEO is usually broken into three parts that work together rather than compete: on-page (what a page says), technical (whether a search engine can access, load, and read it), and off-page (your reputation elsewhere on the web). See What’s SEO? for the full three-way breakdown, and What Is Technical SEO? for the infrastructure side of that split.
Strong off-page signals don’t make up for a site that’s technically broken or thin on content, and the reverse is also true — a technically solid site with good content but no outside credibility tends to plateau, because search engines still look for evidence that a site deserves to rank, not just that it’s well built. All three need to be reasonably solid; none substitutes for the other two.
How Off-Page Signals Show Up in AI-Driven Search
Off-page signals matter for a newer reason too. AI answer engines — Google’s , ChatGPT, Perplexity — tend to lean on sources that already read as credible and well-established, and a meaningful part of what makes a source read that way is exactly what off-page SEO produces: being linked to, cited, and mentioned by other credible sources. None of these companies has published the specifics of how it weighs that kind of outside validation, so it’s worth being cautious about claiming a direct mechanism. What seems reasonable to say: a site that has earned genuine outside recognition through backlinks, press, and mentions is generally the same kind of site that reads as trustworthy to a system trying to summarize a topic accurately.
Common Questions
Is off-page SEO the same thing as link building?
No. Link building is one part of off-page SEO — the deliberate practice of earning backlinks. Off-page SEO is the broader category, which also includes brand mentions, digital PR, citations, reviews, and social distribution. See What Is Link Building in SEO? for the tactics specifically.
Does off-page SEO include social media?
Loosely. Social shares and mentions don’t pass direct ranking credit the way backlinks do, since most social links are nofollow, but social activity can lead to genuine off-page signals — content seen by more people is more likely to get linked to or picked up by press. Treat social as distribution that supports off-page work, not an off-page tactic on its own.
Do brand mentions without a link help SEO?
Possibly, to some degree, though Google hasn’t confirmed unlinked mentions as a direct ranking input. Most SEO practitioners treat consistent, relevant brand mentions as a reasonable side effect of good off-page work rather than something to pursue as a standalone tactic.
How do you measure off-page SEO?
There’s no single official metric. Common proxies include the number and quality of referring domains linking to your site, third-party authority scores like Domain Rating or (the tool makers’ own scoring systems, not figures Google publishes or uses directly), and, for local businesses, review counts and directory consistency. Together they give a rough picture, not a precise score.
Is off-page SEO more important than on-page SEO?
Neither one reliably outperforms the other on its own. A site with strong backlinks and thin, unhelpful content usually underperforms a site that gets both right, and the reverse holds too. See What’s SEO? for how the three disciplines work together.
