Most mistakes with external links start with a blunt rule: nofollow everything that leaves the site. Nofollow external links need more judgment than that, especially when a Shopify or WooCommerce store publishes affiliate content, supplier references, product reviews, and customer Q&A.
The old view treats every external URL as lost “link juice.” High-performing stores treat each link as a relationship signal: paid, user-submitted, editorially trusted, or necessary without endorsement. That distinction protects compliance, improves content quality, and prevents template-level settings from quietly undermining useful resources.
Nofollow External Links: The Short Answer
A nofollow external link is an outbound HTML link containing rel="nofollow". It tells search engines that you do not want to treat the destination as an editorial endorsement, while customers can still click it normally.
It is not an SEO off switch. Nofollow does not guarantee that search engines will not crawl, index, or derive any ranking-related signal from the destination. It is one link-level qualification, not a substitute for noindex, security settings, or a sensible content policy.
Use rel="sponsored" when payment, commission, free products, or another commercial arrangement is involved. Use rel="ugc" for user-generated content. Use nofollow when the link is neither sponsored nor UGC, but your brand does not want to endorse it.
What Does rel="nofollow" Mean?
The rel attribute describes the relationship between the current page and the external website it links to. Adding the nofollow value communicates non-endorsement in an SEO context.
That matters when a link is useful for context but does not deserve your editorial vote. For example, a buying guide may reference a disputed product claim, a low-quality retailer, or a source customers need to identify, without recommending that destination.
Nofollow External Links HTML Example
The code is simple:
<a href="https://example.com" rel="nofollow">Example resource</a>
href is the destination, rel="nofollow" is the relationship signal, and Example resource is the visible anchor text. The shopper sees and uses the link exactly as they would any other link.
A nofollow external links HTML implementation belongs on the actual <a> element. Confirm it in the rendered page source or browser inspector, particularly when a CMS, app, or theme controls links automatically.
Why “Dofollow” Is Informal SEO Terminology
“Dofollow” is convenient shorthand, not an official HTML attribute. It usually means an ordinary link without a nofollow value in its rel attribute.
Do not confuse that label with a quality score. A standard editorial link to a credible, relevant resource can help readers, while a follow link in a manipulative paid placement creates a compliance issue regardless of its label.
Should You Nofollow All External Links?
No. Blanket-nofollow policies solve the wrong problem and often make editorial teams afraid to cite useful sources.
Relevant outbound links can make product education, comparison content, and resource pages more credible. A manufacturer specification, carrier policy, independent study, or payment-provider documentation may give a customer the evidence needed to buy with confidence.
The idea that every outgoing link drains a finite reserve of SEO value is an outdated simplification. For useful context on how links participate in a broader system, review how Google’s link graph can interpret links.
The Modern Reality: Nofollow Is a Hint, Not a Guaranteed Block
Google treats nofollow, sponsored, and ugc as hints for crawling, indexing, and ranking. That means no one can honestly promise that a particular nofollow link will always be ignored or never crawled by search engine bots.
Use the nofollow attribute to communicate the relationship accurately, not to force a precise PageRank outcome. The intent behind the link, its context, and the destination all still matter.
Why Relevant Editorial Outbound Links Can Still Be Valuable
A useful citation can earn trust before it earns a click. On commercial pages, that can mean fewer unanswered questions, stronger buyer confidence, and more useful content for customers comparing options.
A stronger content ecosystem also depends on linking readers to the next genuinely useful resource, not simply withholding every outbound signal. It helps to understand whether do outbound links help seo when you are setting editorial standards around sources, referrals, and authority.
Blanket rules also create operational drift. One team nofollows every supplier link, another leaves affiliate links unqualified, and a plugin applies a global setting to years of blog content.

When to Use Nofollow External Links
Use rel="nofollow" when a link is necessary but you do not want to endorse the destination, and neither sponsored nor ugc describes the relationship better. The link should still serve a clear customer or editorial purpose.
This is not a nofollow external links list to apply blindly. It is a publishing decision: first decide why the link exists, then choose the attribute that truthfully describes it.
Links to Untrusted, Low-Quality, or Non-Endorsed Sources
A brand may need to cite a questionable claim, document a poor customer experience, or identify a site in a fraud warning. In those cases, nofollow helps communicate that the mention is not an endorsement.
Ask two questions before publishing: Is the link necessary for the customer to understand the point? Would your brand comfortably recommend the external website as a resource? If the first answer is yes and the second is no, rel="nofollow" is usually appropriate.
Links in User-Generated Content
Product Q&A, community forums, comments, marketplace reviews, and customer-submitted photos can all contain links. These areas attract legitimate discussion as well as spam, which is why rel="ugc" is the more precise signal.
Your implementation may include both values, such as rel="ugc nofollow", where platform controls support it. More importantly, moderate high-risk submissions and avoid letting a review widget or forum template create uncontrolled outbound-link patterns.
Links That Are Paid, Sponsored, or Affiliate-Driven
Commercial relationships require a more specific signal. Use rel="sponsored" for paid placements, advertising, affiliate product roundups, compensated influencer features, paid directory listings, and links associated with free products or other consideration.
The relationship drives the decision, not whether you personally trust the destination. A respected affiliate partner is still commercial, so the link should be qualified as sponsored.
Nofollow vs. Sponsored vs. UGC: Which Link Attribute Should You Use?
The right attribute should explain why the link exists. This reference table gives editors, affiliate managers, and developers a shared rule before a campaign or article goes live.
| Attribute | Appropriate use case | eCommerce example | Key caution |
|---|---|---|---|
rel="sponsored" |
Paid or compensated relationship | Affiliate link in a “best products” roundup | Use it even when the partner is reputable. |
rel="ugc" |
User-generated content | Link posted in product Q&A or a customer forum | Moderate spam rather than relying on an attribute alone. |
rel="nofollow" |
Necessary link without editorial endorsement | Citation of a disputed retailer claim | Do not use it as a blanket external-link rule. |
| No qualifying value | Editorially endorsed, useful reference | Manufacturer sizing guide or carrier service page | Assess relevance and customer value first. |
Use rel="sponsored" for Paid Links and Affiliate Relationships
Paid links include more than display ads. Affiliate commissions, influencer compensation, partner promotions, gifted products tied to coverage, and sponsored content all create a commercial relationship.
Use rel="sponsored" because it is clearer than treating every paid relationship as generic nofollow. You can combine values where needed, but the key signal is accurate disclosure.
Use rel="ugc" for Comments, Reviews, and Forums
User-generated content sits outside the editorial workflow. A customer may link to a helpful installation video, while another user may post a spam destination in the same review section.
rel="ugc" helps search engines understand that distinction. It is particularly useful on stores with active product Q&A, community sections, or legacy WordPress comments.
Use rel="nofollow" as the Catch-All for Non-Endorsement
Use nofollow when the destination is not paid, not user-submitted, and not something your store wants to recommend. It is the practical catch-all for a necessary non-endorsed reference.
Check four conditions before applying it:
- Necessary context: The destination supports a legitimate customer or editorial need.
- No commercial deal: There is no payment, commission, or compensation involved.
- Not user-submitted: The URL did not originate in comments, reviews, or forum posts.
- No endorsement: Your brand does not want to signal confidence in the destination.
How to Add Nofollow External Links
Correct policy means little if the rendered HTML says something else. Your CMS, theme, editor, app, or plugin may add, remove, or combine rel values, so always verify the front-end output.
Add the Attribute Directly in HTML
Use the applicable value inside the anchor tag:
<a href="https://example.com" rel="nofollow">Non-endorsed resource</a>
<a href="https://example.com" rel="sponsored">Affiliate offer</a>
<a href="https://example.com" rel="ugc">Customer-submitted link</a>
<a href="https://example.com" rel="sponsored nofollow">Paid partner link</a>
Multiple rel values can coexist. Only add each value when it describes a real purpose, rather than loading every possible attribute onto every external link.
Managing External Link Attributes in WordPress and WooCommerce
WordPress editors, SEO plugins, and dedicated link-management tools can provide individual controls or sitewide rules. Review those settings before enabling a global external nofollow option, because it can overwrite sound editorial decisions across product guides and blog posts.
For teams managing large WordPress libraries, explore WP External Links plugin options for WordPress alongside a documented allowlist for trusted editorial destinations. A plugin setting is not a policy, and it does not remove the need to inspect templates and affiliate modules.
Managing Link Attributes in Wix
Wix users can manage rel attributes through link settings, but the same verification rule applies. Publish the change, inspect the live anchor tag, and confirm that a page builder or app has not altered the output.
The platform is secondary to the relationship. A sponsored influencer link needs a sponsored qualification whether the page lives on Wix, Shopify, WooCommerce, or a custom storefront.
How to Check Whether a Link Is Nofollow or Follow
You do not need a developer to check one link. Inspect the rendered anchor tag and look for a rel value containing nofollow.
If no nofollow value appears, SEOs commonly call the link “follow.” Remember that this informal label does not establish whether the link is relevant, trusted, or compliant.
Check a Single Link With Inspect Element
Use this quick process:
- Right-click the link on the live page and choose Inspect.
- Find the
<a>tag that contains the destination URL. - Check the
relvalue fornofollow,sponsored, orugc. - Confirm the rendered output because theme code and scripts can modify links after an editor saves content.
For example, rel="sponsored nofollow" contains nofollow, while rel="ugc" identifies user-generated content without explicitly adding the nofollow value.
Audit Nofollow External Links at Scale
A crawler such as Screaming Frog SEO Spider can collect external links and filter them by rel attribute. That exposes template-level errors across affiliate hubs, product pages, review widgets, editorial articles, and old campaign landing pages.
Track each finding in a simple audit sheet: source URL, destination, link type, current attribute, owner, and required action. That turns a vague cleanup task into an accountable workflow for content, development, and affiliate teams.
Treat attribute errors as part of a wider technical quality review, because template-level changes can affect crawl paths and indexation across thousands of URLs. The broader question of do nofollow links help seo belongs in that review, rather than as a standalone checkbox.

Nofollow, Internal Links, Noindex, and Link Sculpting: Avoid These Mistakes
Outbound-link qualification is not an internal-architecture strategy. Do not use nofollow external links as a substitute for clear category paths, product discovery, canonical controls, or indexation decisions.
Do Not Use Nofollow to Hoard PageRank
“Link juice” is informal shorthand for perceived link equity, and it has encouraged years of poor internal-link practices. Nofollow is not a reliable way to funnel authority toward selected pages or preserve it by withholding useful citations.
Build internal links around shopper intent instead: collections should support products, buying guides should support category discovery, and related products should reduce dead ends. For more context, see a deeper explanation of link graphs and Google rankings.
A healthy authority strategy also recognizes that backlinks in seo are evaluated in context. Relevance, editorial judgment, and audience value matter more than simplistic follow-versus-nofollow labels.
Do Not Treat Nofollow as a Noindex Solution
Nofollow does not guarantee that a page will stay out of search results. If your actual objective is to keep a page from being indexed, use the appropriate indexation control and ensure the page remains crawlable enough for search engines to see it.
Page-level meta robots directives and individual link attributes solve different problems. Review Google’s long-term noindex and follow discussion before treating link signals as a replacement for deliberate indexation management.
Nofollow vs. noopener, noreferrer, target="_blank", and rel="external"
These settings do different jobs. Confusing them creates links that may be secure but unqualified, or qualified for SEO without the intended browser behavior.
nofollow communicates an SEO relationship signal. target="_blank" opens a new tab, noopener limits window-opener access, noreferrer limits referrer information, and rel="external" semantically identifies an outside destination without deciding SEO treatment.
When External Links Open in a New Tab
target="_blank" controls where the browser opens a link. It does not make the link nofollow, sponsored, or endorsed.
Use it only when opening a new context supports the task, such as sending a shopper to a shipping carrier tracker without forcing them to lose their cart. Do not add it merely because a URL is external.
Security and Privacy Attributes Are Not SEO Attributes
noopener prevents a newly opened page from accessing the originating page through window.opener. noreferrer suppresses referral information in the browser request, which can affect analytics and partner reporting.
A valid combined implementation might look like this when each purpose applies:
<a href="https://example.com" target="_blank" rel="sponsored noopener">Partner offer</a>
The sponsored value qualifies the commercial relationship. noopener addresses browser security. Neither one replaces the other.
ECommerce External-Link Policy Checklist
Link governance breaks down when it lives only in one SEO manager’s head. Give merchandising, content, affiliate, and development teams a short rule set that works across new pages and legacy content.
- Affiliate and influencer links: Apply
rel="sponsored"and verify campaign templates. - Customer reviews and Q&A: Use
rel="ugc", moderate submissions, and monitor third-party widgets. - Supplier and manufacturer links: Leave standard editorial links when they genuinely help customers and you endorse the resource.
- Press, marketplaces, and citations: Assess whether the destination is editorially endorsed; use nofollow when it is necessary but non-endorsed.
- Quarterly review: Crawl the site, review high-volume templates, audit commercial content, and assign fixes to an owner.
A Simple Decision Tree Before Publishing Any External Link
Use this sequence every time:
- Is the link user-generated? Use
ugc. - Is it paid, affiliate-driven, sponsored, or tied to compensation? Use
sponsored. - Is it necessary but not editorially endorsed? Use
nofollow. - Is it relevant, useful, and genuinely recommended? Use a standard link.
- Has the rendered HTML been checked after publishing? Verify it before closing the task.
This approach keeps external links useful without turning every writer into a technical SEO specialist. It also gives your team a clean record when affiliate, legal, or brand teams ask why a link was published.
FAQ: Nofollow External Links
What Does It Mean When a Link Is Nofollow?
A nofollow link contains rel="nofollow" and signals that the publisher is linking without editorial endorsement. Users can still click it, and search engines may treat the signal as a hint rather than an absolute command.
What Are Examples of External Links?
External links point from your site to another domain. For an eCommerce store, they may lead to manufacturers, suppliers, payment providers, shipping carriers, editorial sources, affiliates, social profiles, review platforms, or third-party tools.
Are Nofollow Links Good for SEO?
Asked “are nofollow links good for seo?”, the answer is that they are not inherently good or bad for SEO. Their value can include relevant referral traffic, brand awareness, customer trust, and a natural link profile, but you should choose them based on the link relationship rather than a presumed ranking benefit.
How Do You Tell if a Link Is Dofollow or Nofollow?
Right-click the link, select Inspect, and find the <a> tag. If its rel attribute contains nofollow, it is nofollowed; if it does not, it is commonly called a follow link. Use a crawler to check thousands of links at once.
Build a Safer, More Useful External-Link Strategy
Treat nofollow external links as a precise publishing control, not a panic button. Keep useful editorial citations available to customers, use sponsored and ugc when they accurately describe the relationship, and validate rendered HTML instead of trusting plugin defaults.
