What Is Off-Page SEO? A Practical Guide Centered on Earning Backlinks
The overall picture of SEO can be broadly divided into three areas: on-page measures, content measures, and off-page measures. Of these, off-page measures aim to raise your site's evaluation from the outside, and at their core is earning backlinks. This article clearly explains what off-page SEO is, starting from the basics, how it differs from on-page SEO, specific practical measures centered on earning backlinks, and the NG tactics you should avoid.
Off-page SEO refers to the collective set of measures that raise the evaluation your site receives from external sources and earn trust from search engines. In contrast to on-page SEO, which optimizes the inside of your site, off-page SEO can be described as the effort to improve “how others evaluate you.”
At the center of this is earning backlinks. Search engines treat links from external sites as “recommendations (votes) from other sites,” so a page that is linked to by many trustworthy sites tends to be evaluated as valuable, high-quality information worth referencing. Off-page SEO is easiest to understand as the activity of gathering this kind of natural evaluation.
Beyond earning backlinks, off-page SEO also includes efforts to increase mentions (citations) on social media and other media, raising recognition and trust across the web as a whole. All of these are measures that pursue “how to become an entity that is well evaluated outside your own site.”
To understand where off-page SEO fits, let's first organize its role within SEO measures as a whole. SEO is generally divided into the following three areas.
These three are not independent; they support one another. In particular, off-page measures are an area where results emerge naturally only when high-quality content exists, so it is essential to consider them together with content measures.
On-page and off-page measures differ greatly in “where you act” and “the range you can control.”
On-page measures are completed within your own site, so you can control them directly with your own hands. Optimizing titles and headings, organizing internal links, and improving page speed are all measures you can start on right away if you choose to.
On the other hand, with off-page measures, the operator of the other site decides whether or not to place a link, so you cannot control it directly. That is precisely why the basic approach is to create “a reason to want to link” and indirectly encourage acquisition. Because it is harder to control, it takes time for results to appear, but the trust you earn becomes an asset that works over the medium to long term.
Off-page measures are emphasized because backlinks are a signal that represents “objective evaluation from third parties” to search engines. No matter how much you insist your site is valuable, its persuasiveness is limited; but if you are referenced by many trustworthy sites, that becomes external corroboration.
The prototype of this idea is the concept of PageRank, known since Google's early days. It treats links like votes and judges that pages receiving votes from highly evaluated sites are more important. Even now, with algorithms having evolved into great complexity, the basic idea of “referencing links as evaluation from others” remains alive.
However, note that today “quality” is valued more than “quantity.” A small number of links from highly relevant, trustworthy sites is far more valuable than a large number of links mechanically gathered from unrelated sites. Off-page SEO is the activity of “gathering good links naturally,” not the task of racking up a count.
Sound off-page SEO is built not on superficial tricks but on “creating a reason to want to link.” Centered on earning backlinks, here are some representative practical measures.
The starting point of off-page SEO is preparing high-quality content that other sites will want to introduce. Original survey data, easy-to-understand explanatory articles, and handy tools or templates tend to be cited as references. Links gather as a result of good content, so creating value that people want to cite is the top priority first.
First-party information such as surveys you conduct yourself or industry research is easy for other media and blogs to cite as evidence, and it leads directly to earning backlinks. Original data like “a survey on XX” naturally gathers links as a source and becomes an asset that keeps generating backlinks over the long term.
Even excellent content will not be linked to if no one knows about it. By delivering content to many people through social media, newsletters, and external information sharing, you increase the chances that those who see it will introduce it on their own sites. The direct SEO effect of social media links themselves is said to be limited, but they serve as an important foundation of off-page SEO by creating opportunities for natural backlinks through expanded awareness.
Contributing to related media, responding to interviews as an expert, and collaborating on events or joint research lead to natural backlinks from highly trustworthy sites. It is preferable to earn links as a result of genuine activity, and you should avoid low-quality contributions made solely for the purpose of getting links.
When your company name or service name is mentioned on another site but no link is placed, you can sometimes have it turned into a link by asking politely. This is a realistic, highly reproducible off-page measure that makes use of a state where you are already mentioned—meaning you have already earned a degree of evaluation.
Mentions without links (citations) are also gaining attention as an element that raises brand awareness and trust. A state in which your company is named in many places leads to a sense of presence across the web as a whole, and it also becomes fertile ground for natural backlinks to emerge as a result.
The most important thing in off-page SEO is “being natural.” Acquiring unnatural links solely for the purpose of manipulating rankings violates Google's spam policies and risks having evaluation discounted or incurring a penalty. The following tactics should be avoided.
Such unnatural links were, in the past, clearly targeted for penalties by updates like Penguin. It is said that processing to “ignore” illegitimate links is now also progressing, but the fact that risk remains is unchanged, and you should avoid resorting to tactics that violate the guidelines in pursuit of short-term effects.
Off-page measures do not end once you implement them; grasping the situation and managing it also matters. The “Links” report in Google Search Console lets you check for free which sites are linking to your site. If you want to analyze in more detail, SEO tools such as Ahrefs or Semrush let you grasp the number of backlinks, referring domains, and anchor text trends.
In the unlikely event that a malicious site places a large volume of unnatural links and a clear negative impact is feared, you can use Google's “link disavow” tool to declare that specific links be excluded from evaluation. However, this is a last resort for advanced users and is usually unnecessary. Because Google says it automatically ignores many illegitimate links, careless disavowal can actually be counterproductive.
Off-page measures are powerful, but they do not produce results on their own. To gather links, you need, as a prerequisite, high-quality content people want to cite (content measures) and a site structure that lets search engines correctly understand the content (on-page measures).
In other words, off-page measures only take effect on the foundation of “good content and a sound site.” In terms of order, the healthy flow is to first solidify the foundation with on-page and content measures, then earn backlinks naturally as you spread that value to the outside. Combining the three measures in good balance leads to stable results.
Off-page SEO refers to the collective set of measures that earn external evaluation and trust for your site, such as backlinks and mentions on other sites. At its core is earning backlinks, and search engines reference links as “recommendations from third parties.”
However, what is evaluated is quality, not quantity. The shortcut to earning high-quality backlinks is to publish content and original data people want to cite and to expand awareness through social media, contributions, and the like. On the other hand, unnatural tactics like buying links or creating self-made links carry risk and should be avoided. Considering off-page measures together with on-page and content measures, and aiming for a state where links gather naturally as a result of good content, is the key to soundly growing your results.
