What is off-page SEO?

Short answer

Off-page SEO is everything that happens away from your own website that affects how Google ranks it. Links from other sites are the biggest part. Mentions, reviews and directory listings are the rest. The test that matters is whether a real audience would plausibly see and follow the signal, because the ones built only for search engines are the ones that stop working.

On-page SEO is about making a page a good answer. Off-page SEO is about evidence from elsewhere that the page, and the business behind it, deserve to be trusted. Google cannot read your content and know whether you are reputable. It looks at what the rest of the web says about you.

What counts as off-page SEO

Links from other websites. Still the largest off-page signal. Google uses links to discover pages and to judge their importance.
Brand mentions. Your name on other sites, in news, in industry publications, with or without a link.
Reviews. On Google and on the platforms that matter in your industry. Especially important for local businesses.
Citations. Consistent business name, address and phone number on directories and data sources.
Your Google Business Profile. Technically off your website, and for local businesses the most important off-page asset.

For local search, Google says this directly. It describes prominence, one of its three local ranking factors, as drawing on information Google has about a business from across the web, like links, articles and directories, along with review count and score.

Not all links are equal

The most common off-page mistake is treating links as a number to increase. What matters is where they come from. Ahrefs studied 44,589 keywords and found that the total traffic to the pages linking to you correlated with rankings better than the simple count of links. A link from a page real people read and click is worth far more than a link from a page that exists only to hold links.

Relevance matters too. A link from a site your customers actually read, in your industry or your town, outweighs a stack of high-metric links from sites with no connection to what you do.

What does not count, or carries risk

Google’s spam policies describe link spam as links intended to manipulate rankings, and name buying or selling links for ranking purposes, excessive link exchanges, automated link creation, and large-scale article or guest post campaigns with keyword-rich anchor links. Those can lead to a manual action, or more often, simply to the links being ignored.

Low-value directories, profile links, comment links and anything produced in bulk tend to be ignored rather than punished. They cost money and do nothing.

And chasing mentions for their own sake. Google’s guidance on generative AI search notes that seeking inauthentic mentions across the web isn’t as helpful as it might seem.

How off-page and on-page fit together

Links make a page competitive. They cannot make an unsuitable page relevant. Building links to a page that does not match what people search for is wasted effort. Building them to a site whose internal links bury the important pages wastes some of it too, because the authority cannot reach the pages that need it.

That is why I treat internal linking as part of off-page work in practice. Before chasing new links, point the strength you already have at the pages that earn money.

Where to start

For a local business: the Business Profile, reviews and consistent citations first. These are the off-page signals that most directly affect the map pack, and most of them are in your control.

For any site: find who links to your competitors and not to you, and why. Some of those sites will have a genuine reason to link to you too: a supplier, an industry body, a local organisation, a publication that covers your field. That list is usually more valuable than any link package.

Then make something worth linking to. Data, a useful tool, a genuinely helpful guide, or expertise a journalist or blogger needs. Content does not earn links on its own; someone has to know it exists. I wrote about that in why great content does not earn links on its own.

How long it takes

Months, typically. Links are earned slowly and their effect builds over time. Anyone promising ranking movement from links within weeks is either selling something that will not last or taking credit for something else.

A test for any off-page activity

Before you pay for or spend time on any off-page tactic, ask one question: if this link, listing or mention appeared on a public list of everything pointing at your site, would you be comfortable showing it to a customer? A feature in a local paper, a supplier’s partner page, a professional association listing all pass easily. A network of thin blogs, a hundred directory submissions or a paid placement on a site nobody reads do not. In my experience the second group is where most off-page budgets go, and where most of the cleanup work I am later hired for comes from.

If you want off-page work you would be comfortable showing anyone, my link building service earns fewer links, from places with a real reason to link to you.
