What Is Off-Page SEO? What Counts, What Google Allows and How to Track It

What Is Off-Page SEO?

Quick answer: What is off-page SEO? It is everything that happens outside your own website and changes how Google and people see it: mainly links from other sites, plus mentions of your brand, reviews and recommendations. You can influence these signals but not control them, and a few tactics break Google's rules.

Some guides call it off-site SEO, and the links involved are also called backlinks or inbound links. Google's SEO Starter Guide points to why this work is mostly earning, not placing. Google says it primarily finds pages through links from pages it already crawled, often other websites, and that other sites linking to you "is something that happens naturally over time". You can encourage that by promoting your site, but you cannot order a link the way you order a title tag.

Read the last column twice, because it shows where effort pays.

So what is off-page SEO not? Your titles, headings, copy and internal links are on-page, because you place them. Crawling, speed and indexing belong to the technical side.

Off-Page SEO vs On-Page SEO vs Technical SEO

The on-page vs off-page SEO question gets muddy because technical SEO overlaps both. Here is the split. For the full set of types and how they fit together, see the types of SEO and which ones your site needs.

• On-page SEO is what you control on the page itself: content, title, headings and the links between your own pages. Our on-page SEO guide goes deeper.
• Technical SEO decides whether Google can crawl, render and index your pages, which comes down to status codes, robots.txt and speed.
• Off-page SEO, or off-page optimization, is what other people and sites do about you: links, mentions and reviews.

Internal links are links, but they are on-page, because you place them. Our internal links guide has the check and the fixes.

All three act on the same page, and that is the practical point. If the page that earns a link is slow, blocked, throws an error or says very little, the link sends people to a bad page. So check the landing page before you chase more links. That rule is ours, not Google's.

Why Off-Page SEO Matters: What Google Says About Links

Off-page SEO matters because links are how Google mostly finds new pages, and links or references from prominent sites are one of the quality factors it uses. But PageRank, often called link equity, is one signal among many, and the Google pages we read give no weights. Treat off-page work as a helper, not a lever you can size.

• In its description of how Search ranks results, Google says one of the factors used to judge quality is whether other prominent websites "link or refer to the content", which it calls "generally a good sign". Note the word refer: Google adds no detail about mentions, so do not assume they pass anything.
• Google's ranking systems guide says PageRank was one of its core ranking systems at launch, that how it works "has evolved a lot", and that it is still part of the core systems.
• The SEO Starter Guide says PageRank uses links but is just one of many ranking signals.
• Google's guide to how Search works says relevancy is determined by "hundreds of factors", and its page on ranking results adds that the weight of each varies with the query.

Those pages describe off-page SEO factors in general terms and give no weights or ordering, so a claim that links make up a set share of ranking, or outrank every other signal, has no support in them.

Links also carry discovery: the starter guide says the vast majority of the new pages Google finds every day are found through links. Our guide to how Google crawls websites covers that side.

The ranking systems guide adds that Google runs a range of spam detection systems, including SpamBrain, and that the Penguin system, built to combat link spam, was announced in 2012 and folded into the core ranking systems in 2016. So there is no separate Penguin update to wait for. Google also says it does not accept payment to crawl a site more often or rank it higher, so paying for rankings is a rules problem, not a shortcut.

Off-Page SEO Techniques That Stay Inside Google's Rules

These off-page SEO techniques work because a person chooses to link, mention or recommend you. Think link earning, not link building. For a numbered how-to, see our link building tips, twelve ways to earn and keep links inside Google's rules.

Publish something other people want to cite

Original research from your own tests, a free tool or a clear reference page gives people a reason to link. Put a date and a method next to every number, so a journalist can check it. The rule: promote it freely, but let the links come from people who chose to give them, because paying or trading for them lands you in the next section.

Contribute as an expert

Guest posting, podcast interviews and expert quotes put your name in front of an audience that already cares, which is digital PR in practice. Use plain anchor text, such as your brand or the page title, so the result is a natural link. The rule: Google's link spam policy names advertorials where payment is received for articles with links that pass ranking signals, and optimized anchor text in articles, guest posts or press releases distributed on other sites. It targets those versions, not guest content as such. Label anything paid rel=sponsored.

Reclaim and replace links

Broken link replacement: find a dead link on a relevant page and suggest yours. Link reclamation: if a site uses your image or tool without a link back, ask politely for one. Our reverse image search tool helps with the second: it builds links that open Google Lens, Bing and Yandex with your image or image address, and the engines do the matching, because we keep no image index. Uploaded pictures stay at a random public link for about two hours, so anyone with that link can open them. The rule: ask, do not trade, because goods or services in exchange for a link is on Google's list.

Earn real reviews and complete local listings

Google Business Profile help says local results are mainly based on relevance, distance and popularity, and that prominence, the third factor, also reflects how many websites link to your business and how many reviews you have. More reviews and positive ratings can help local ranking, so ask real customers for online reviews and keep your name, address and phone number identical everywhere (NAP consistency). Our local business listings guide covers local citations. The rule: Google's contribution policy does not allow payment, discounts or free goods in exchange for reviews.

Take part where your audience already talks

Communities, newsletters and social profiles can lead to links and mentions. The starter guide lists social media promotion, community engagement, advertising and word of mouth as ways to promote a site, and warns that you can overdo it. The rule: help first and link only when the link answers the question, because the spam policy lists forum comments with optimized links in the post or signature as link spam.

Partnerships and sponsorships

Sponsoring an event or a community project, or co-writing with a related business, can earn a real mention and a link. The rule: a link that comes from a paid sponsorship should carry rel=sponsored or nofollow, which is also what Google asks for.

What to Avoid: Link Spam, Paid Links and Link Schemes

Google's link spam policy defines link spam as creating links to or from a site primarily to manipulate search rankings. Its main examples, shortened:

• Buying or selling links for ranking, whether you pay with money, goods, services or a free product sent for a write-up with a link.
• Excessive link exchanges, and partner pages that exist only for cross-linking.
• Using automated programs or services to create links to your site.
• Requiring a link in your terms of service or a contract without letting the other owner qualify it.
• Paid advertorials, and optimized anchor text in guest posts or press releases distributed on other sites.
• Low-quality directory and bookmark site links.
• Keyword-rich links in widgets, and widely distributed footer or template links.
• Forum comments with optimized links in the post or signature.

Google's page does not use the term private blog network. Our reading: sites built to link to each other, or to one site, to lift rankings fit its definition of link spam.

Paid is not the problem, though. Google says buying and selling links is a normal part of the web's economy for advertising and sponsorship, and such links are not a violation when qualified with rel=nofollow or rel=sponsored. The problem is a paid link that passes ranking signals without a label.

Google finds violations through automated systems and, as needed, human review that can result in a manual action, and sites that break the spam policies may rank lower or not appear at all. For links, the manual action shows in Search Console as "Unnatural links to your site". Google's recovery steps: download your links, ask the site owner to remove the link or stop it passing PageRank, disavow only what you could not get removed, then select Request Review with documentation.

Disavow: Google says most sites will not need the Disavow links tool, because it can usually assess which links to trust. Use it only if you have a considerable number of spammy, artificial or low-quality links and they have caused, or are likely to cause, a manual action. It can harm performance if misused, and disavowed links stay visible in the Links report.

For the wider ethics, read our post on black hat and white hat strategies.

Nofollow, Sponsored and UGC: Which Link Attribute Fits

Off-page work meets these three rel attribute values the moment a link is paid for, gifted or posted by a user.

You can combine values, for example ugc and nofollow together. Google treats all three as hints, not commands. It announced the change on the Google Search Central blog in September 2019, and nofollow became a hint for crawling and indexing on March 1, 2020. Links marked this way will generally not be followed, though the linked page can still be found through sitemaps or links from other sites.

To stop Google fetching a page on your own site, use a robots.txt disallow rule. To keep a page out of the index, allow crawling and use noindex. Nofollow is the wrong tool for both.

If you pay for a placement, or get something in return, ask for rel=sponsored and expect the link to carry it. A link with one of these values can still send visitors and build recognition, so it is not worthless, though that is our view, not Google's. Our nofollow guide has the HTML and WordPress steps, and Google's guide to qualifying outbound links has the full wording.

How to Judge a Link Before You Chase It

These six tests are our working checklist, not a Google formula. Use them to decide where your next month goes.

• Would a real reader click it? The linking page should cover something close to your topic.
• Did a person choose to place it? A profile, comment or directory entry you added yourself is not an editorial link, and editorial links are the goal.
• Is the site real? Look for original content, no thin pages, no unrelated casino or pharmacy links, and no openly advertised placements.
• Where does it sit? Inside the body copy is natural. Google lists keyword-rich links in widgets spread across sites, and widely distributed footer or template links, as link spam.
• Does the anchor text read like a person wrote it? Your brand, the page title or a plain description beats the same keyword phrase every time.
• What does the page source say? Look for rel=sponsored, rel=ugc or rel=nofollow, which shows how the site itself labels the link. The Links report does not show that.

An illustration, not data: a regional food blog links to your bakery page inside a roundup, in plain text, because a person liked your sourdough. Keep that one. A footer link repeated across many unrelated sites with the anchor "cheap cakes london" fails several of the tests above.

A high score on a third-party authority metric does not make a link good, and the Links report gives counts and link text, not a quality score. Use such numbers only to compare domains over time, never to judge a single link.

How to Monitor Off-Page SEO for Free

The first questions about your own links have free answers.

1. Open the Links report. In Google Search Console, choose Links, then External links, and read Top linked pages, Top linking sites and Top linking text. Internal links is a separate table. Google's help page for the Search Console Links report has the details.
2. Check Manual actions. Open the Manual actions report and look for "Unnatural links to your site". The recovery steps are in the rules section above.
3. Look up your domain. Run it through the free Domain Authority Checker, one domain per check for guests and up to five domains with a free account.
4. Search your brand in quotes. Once a month, run your brand searches, spot new mentions and note the unlinked ones. A polite request for a link costs nothing. That habit is ours.

What the Links report can and cannot tell you. Google groups the data by root domain, so www, m. and other subdomains fold together. Each table holds up to 1,000 rows, and the report is a sample, not a comprehensive list. It includes links found over time, which may since have been removed, and it does not say whether a link is nofollow. Top linking sites works as your list of referring domains, and the link export lets you keep a monthly copy.

What the Domain Authority Checker shows. Type a domain such as example.com; a full address is reduced to its domain. In late October 2026 the checker answers with a free link-graph rank from Common Crawl, and the result carries a note that names that source. For example.com it printed "Rank score 78/100, global rank #63, PageRank position #192, 8,250 known hosts". The data covers about 135 million domains from the Aug to Oct 2026 release. Our guide on how to check domain authority explains what each kind of answer means.

The score is a log scale built from a domain's harmonic centrality position, so 100 is the top domain and 0 the last. The PageRank position is Common Crawl's own ordering, not Google's PageRank. A subdomain is reduced to its registered domain, and a young or small site may come back as "not in the Common Crawl link graph yet".

Read it carefully: a rank score says how well linked a domain is overall. It cannot tell you which links are good or whether any were paid for, and the page labels it as not a Domain Authority or Page Authority score, so do not compare the two. Read the note beside the result first, because it names Common Crawl as the source. For what Page Authority and Domain Authority are and what Google says about them, see our guide to page authority vs domain authority.

Off-Page SEO Checklist: A 30-Day Routine for a Small Site

This is a routine, not a forecast. Run it once, then repeat the last step every month.

1. Week 1: see where you stand. Open the Links report, choose External links, and note your three most linked pages and your five top linking sites. Export the list.
2. Week 1: check the landing pages. Those three pages are where your links land, so a page that fails basic checks wastes the link. Next, run the free SEO Site Checker report on each one.
3. Weeks 2 and 3: earn something. Improve one page worth citing, then ask up to ten people or sites that already mention you, or use your images, for a link.
4. Week 3: local basics. Complete your Business Profile and listings, and ask recent customers for reviews.
5. Week 4: review. Check the Links report for new links, confirm nothing paid went live without rel=sponsored, then repeat next month.

The report audits the page you enter, with more than 60 checks, and it does not look at backlinks. That is why the routine points it at your landing pages and not at your link profile. A free account only raises limits.
