WordPress has made a big change since version 5.1. It now adds rel=”noopener noreferrer” to new-tab links by default. This small change affects millions of pages online. It can impact website traffic, analytics, and security in ways many teams don’t notice.
This guide will show you how to use ‘nofollow’ with rel ‘noopener noreferrer’. It’s all about protecting users and keeping data clean while keeping your site ranking well. You’ll learn where each link attribute fits, how it works with the Google algorithm, and why SEO is all about simple, smart defaults.
Noopener stops reverse tabnabbing, and noreferrer hides the referrer. Nofollow signals search engines. You’ll discover SEO best practices that balance safety, privacy, and measurement. With the right approach, you’ll keep link equity flowing, avoid broken affiliate tracking, and support steady website traffic.
If you manage a SaaS dashboard, an ecommerce storefront, or a content site, this is crucial. The wrong mix can mess up reports in Google Analytics, weaken backlink visibility in Ahrefs and Semrush, and slow growth. The right mix uses each attribute carefully, supports SEO, and aligns with the Google algorithm without guesswork.
What ‘noopener’ and ‘noreferrer’ actually do for security and privacy
Opening a link in a new tab might seem easy, but it can be risky. Using the right link attribute is key for safety and SEO. It helps protect users and their data without hurting search rankings.
In short, these attributes harden browser behavior, cut off risky pathways, and reduce data leaks. They matter most when you use target=”_blank”.
rel=”noopener”: preventing reverse tabnabbing via window.opener protection
When a new tab opens, the page can try to control the original tab. This is called reverse tabnabbing. rel=”noopener” stops this by removing the opener reference. It blocks attempts to hijack sessions or trick users into fake login pages.
Use this link attribute for any external page opening in a new tab. It’s a small step that greatly improves user trust and SEO.
rel=”noreferrer”: hiding the HTTP referrer for privacy
rel=”noreferrer” removes the HTTP referrer header. This means the site you visit won’t see where you came from. It helps keep private paths, campaign codes, and sensitive page names safe.
Privacy benefits are clear, but it might make analytics harder. Balance tracking needs with SEO by using rel=noopener noreferrer only when privacy is key.
Browser support and modern defaults for noopener behavior
Chrome, Safari, Firefox, Edge, Opera, and major mobile browsers all support these attributes. Many now use noopener by default for target=”_blank”.
Even so, add rel=”noopener” explicitly for consistent behavior. Pairing it with rel=”noreferrer” is common. But use both with care to protect users and SEO goals.
How these link attributes affect search engine optimization
Link attributes shape how pages behave without rewriting SEO rules. They support a strong website ranking and keep users safe. The google algorithm looks at content, links, and intent; these attributes help with that.
Key idea: use rel=”noopener” for user safety and rel=”noreferrer” for privacy. This balance also protects website traffic insights.
Direct vs. indirect SEO impact: rankings, crawling, and PageRank flow
Rel=”noopener” and rel=”noreferrer” don’t change rankings directly. They don’t stop crawling or block PageRank flow. The google algorithm can still check links and context, so your ranking depends on relevance, quality, and structure.
The indirect effects show up in tracking and diagnostics. When teams see fewer signals, they might scale back outreach. This can slow real gains in website traffic. See these attributes as safety and privacy tools, not ranking levers.
Why rel=”noreferrer” can reduce visibility in analytics and backlink tools
Rel=”noreferrer” removes the referrer header. Traffic from partners or press may show as “Direct” in Google Analytics. Backlink platforms like Ahrefs, Semrush, and Moz use referrer data for discovery and reporting, so visibility can drop.
This doesn’t harm SEO, but it can hide campaign performance. If you need to attribute conversions or content syndication, avoid rel=”noreferrer”. This keeps a clear view of website traffic sources.
Maintaining website ranking signals while protecting users
Use rel=”noopener” by default for links that open in a new tab. It protects sessions without affecting ranking signals or crawl paths. This keeps the google algorithm focused on content quality and link context.
Apply rel=”noreferrer” only where privacy is key, like sensitive resources or support pages. For affiliates, UTM campaigns, and media mentions, skip it. This preserves reporting and link-building insights that support SEO and steady website ranking.
rel=”nofollow” vs. rel=”noopener noreferrer”: different goals, smart combinations
These attributes solve different problems. One talks to search engines, the other to browsers. Using them together protects users and keeps your link strategy in line with SEO and Google’s rules.
Nofollow as a search engine directive vs. noopener/noreferrer as browser directives
Use rel=”nofollow” to mark links as untrusted for search rankings. It tells search engines not to pass PageRank. This is a search engine directive.
Use rel=”noopener” to block window.opener and stop reverse tabnabbing. Use rel=”noreferrer” to hide the referrer header. These are browser directives and don’t affect link equity under Google’s algorithm.
When to pair nofollow with noopener and/or noreferrer
For outbound links that open in a new tab, add rel=”noopener” by default. If the link doesn’t need referrer data, add rel=”noreferrer” too.
When a link is paid or user-submitted, include rel=”nofollow” alongside rel=”noopener.” Keep rel=”noreferrer” only if losing referral analytics is okay. This balance meets SEO standards without compromising safety.
Use cases: sponsored, UGC, and untrusted links
- Sponsored posts and affiliate widgets: rel=”nofollow” + rel=”noopener”; consider rel=”noreferrer” if privacy beats tracking needs.
- User-generated content on Reddit-style threads or YouTube comments: rel=”nofollow” + rel=”noopener” to reduce risk from unknown destinations.
- Untrusted directories or ad networks: rel=”nofollow” + rel=”noopener”; add rel=”noreferrer” when you want stricter privacy.
- Trusted editorial citations to The New York Times or Mozilla: avoid nofollow; keep rel=”noopener”; use rel=”noreferrer” only if referral data is not needed.
| Scenario | Goal | Recommended rel | Reasoning |
|---|---|---|---|
| Sponsored placement | Compliance and safety | nofollow, noopener | Follow SEO best practices for paid links while preventing tabnabbing. |
| UGC comment link | Limit risk | nofollow, noopener | Mark as untrusted and block window.opener exploits. |
| Untrusted external tool | Privacy and control | nofollow, noopener, noreferrer | Reduce attack surface and hide referrer when needed. |
| Editorial citation | Pass signals | noopener | Keep user security without using nofollow links unnecessarily. |
‘nofollow’ with rel ‘noopener noreferrer’
Linking out should be safe and smart. Using ‘nofollow’ with rel ‘noopener noreferrer’ is a clear strategy. It protects users and helps with search engine optimization. This approach keeps your website ranking high while avoiding security issues.
In practice, each attribute has a job. Nofollow tells search engines how to handle PageRank. Noopener stops unwanted page changes. Noreferrer keeps the referring URL private. Together, they ensure safety without losing user trust or site performance.
Why combining attributes can improve safety without blocking link equity
Combining nofollow with noopener and noreferrer is smart. Nofollow handles link equity, while noopener ensures safety. Noreferrer adds privacy. This way, you can secure links and meet SEO goals.
For trusted links, you might skip nofollow. But keep noopener for security. This balances safety and SEO.
Google’s stance: PageRank and crawling with noreferrer in place
Google says rel=”noreferrer” doesn’t stop crawling or PageRank transfer. Nofollow is the key for equity, not noreferrer. So, you can use noreferrer for privacy without losing SEO value on links that help your website ranking.
When the combo is ideal for external links in new tabs
Use nofollow + noopener for sponsored, UGC, and untrusted links in new tabs. Add noreferrer for privacy. For editorial links, open in a new tab with noopener. Decide on nofollow based on trust and policy. Use noreferrer only if losing referrer insights won’t harm reporting.
| Scenario | Recommended Attributes | Reasoning | Impact on SEO |
|---|---|---|---|
| Sponsored or affiliate links | rel=”nofollow noopener” (add noreferrer if privacy needed) | Prevent tabnabbing; signal paid nature; optional privacy | Nofollow limits equity; noreferrer does not affect crawling |
| UGC or untrusted links | rel=”nofollow noopener noreferrer” | Reduce risk and hide referrer when safety is priority | Equity restricted by nofollow; crawling unaffected by noreferrer |
| Editorial, trusted links | rel=”noopener” (consider noreferrer) | Protect users without blocking value | Supports website ranking when nofollow is omitted |
| Privacy-sensitive outbound clicks | rel=”noopener noreferrer” | Stop reverse tabnabbing and hide referrer | Preserves link equity since nofollow is not used |
Best practices for external links, affiliate links, and internal navigation
Having clear rules for each link type keeps users safe and analytics accurate. Follow seo best practices for every link attribute. This ensures your content flows well, your reports stay clean, and your website traffic trends remain trustworthy.
External links opened in new tabs: always use rel=”noopener”; consider noreferrer
When you use target=”_blank”, add rel=”noopener” to stop reverse tabnabbing. This link attribute blocks window.opener access and reduces risk without changing how search engines crawl.
Consider rel=”noreferrer” if you want extra privacy. It hides referrer data and may shift some website traffic labeling in analytics. Apply it when user protection beats referral reporting needs.
Affiliate and tracked links: avoid rel=”noreferrer” to preserve attribution
Affiliate programs like Amazon Associates, PartnerStack, and Impact rely on referrer and UTM data. Using rel=”noreferrer” can break session handoffs and cost commissions.
Use rel=”noopener” for security and leave referrer data intact. This balance meets seo best practices, keeps each link attribute purposeful, and preserves website traffic attribution across GA4 and HubSpot.
Internal links: do not use noopener/noreferrer; keep site architecture clear
Internal links should not carry noopener or noreferrer. They add no protection in same-domain navigation and can muddle analytics and crawl paths.
Keep anchors clean so PageRank flows and menus remain consistent. This supports site structure, improves discovery, and stabilizes website traffic patterns.
| Link Type | Goal | Recommended Attributes | Why It Works | Impact on Analytics |
|---|---|---|---|---|
| External (new tab) | Protect users | rel=”noopener”; consider rel=”noreferrer” | Prevents reverse tabnabbing; optional privacy from hiding referrers | Noopener intact; noreferrer may shift referrals to Direct |
| Affiliate / Tracked | Maintain attribution | rel=”noopener” only | Security without stripping referrer used by networks and GA4 | Preserves source/medium and partner payouts |
| Internal | Reinforce architecture | No noopener or noreferrer | Clear crawl signals and smooth UX within the same domain | Stable reporting for navigation and on-site flows |
Implementation guidance: manual HTML, CMS defaults, and audits
Getting link attributes right starts in the code and ends in your templates. Follow seo best practices to protect users and keep data safe. Use rel=noopener noreferrer and nofollow wisely, based on the link’s purpose.
Manual anchor syntax examples for secure external linking
Use clear patterns that match user goals. Keep tracking when needed and add privacy when it’s important. Each link attribute should have a purpose.
- Secure with tracking preserved: <a href=”https://example.com” target=”_blank” rel=”noopener”>Visit Site</a>
- Privacy-focused: <a href=”https://example.com” target=”_blank” rel=”noopener noreferrer”>Visit Site</a>
- When a directive is needed: <a href=”https://example.com” target=”_blank” rel=”nofollow noopener”>Visit Site</a>
Keep your code clean, avoid duplicate attributes, and make sure rel=noopener noreferrer or nofollow fits the link’s context.
WordPress automatic insertion for target=”_blank” and how to override
WordPress adds rel=”noopener noreferrer” to new-tab links. This is good for safety but can hide referrers. If affiliate reporting or partner analytics are important, edit the HTML to keep rel=”noopener” only.
Use Blocks or the Code Editor to adjust the link attribute as needed. Save, then retest the page to ensure nofollow or noreferrer were not reinserted by a plugin.
Shopify, Webflow, Wix, and Squarespace nuances
Platform defaults vary, so test before rollout. In Shopify, behavior often depends on the theme. You may need Liquid changes or an app to control each link attribute cleanly.
Webflow and Squarespace usually require manual edits for rel values. Wix may add noreferrer by default, which can be hard to override; confirm whether your design tools or apps add rel=noopener noreferrer automatically.
Sitewide audits with Screaming Frog and template overrides
Run a crawl to list all external links with target=”_blank”. Check that noopener is present, and flag places where noreferrer was added to tracked links. Align fixes at the template level to prevent regressions.
For large catalogs and blogs, use redirects managed by tools like Pretty Links to standardize parameters. Then update layouts so nofollow appears only where policy requires it, while preserving seo best practices across templates.
| Scenario | Recommended rel | Main Goal | Risk if Misapplied | Validation Step | External article in new tab |
|---|---|---|---|---|---|
| noopener | Prevent reverse tabnabbing | Security exposure without noopener | Crawl for target=”_blank” without noopener | ||
| Privacy-first outbound link | |||||
| noopener noreferrer | Limit referrer leakage | Lost analytics if unintended | Check referral reports after publish | ||
| Affiliate link with tracking | |||||
| noopener | Preserve attribution | Commission loss with noreferrer | Test conversions and referrer data | ||
| Sponsored or UGC link | |||||
| nofollow noopener | Signal to search engines | Link equity passed if nofollow missing | Spot-check rel values in templates | ||
| CMS default adds noreferrer | |||||
| Override as needed | Keep data for partners | Incorrect “Direct” traffic in analytics | Audit changes after theme/plugin updates |
Analytics and reporting: preserving referral and campaign data
Accurate reporting is key to keeping budgets in check and ensuring SEO efforts are effective. When referrals disappear, it can mess up website traffic trends. This can affect how well tests work with the google algorithm or the impact of nofollow links.
Use clear link policies before rolling out changes across templates or a CMS. Small changes to link attributes can change how platforms like Google Analytics, HubSpot, and affiliate dashboards track clicks.
How rel=”noreferrer” shifts traffic to “Direct” in GA
Adding rel=”noreferrer” removes the referrer header. In GA4, many clicks are now marked as “Direct,” not “Referral.” This makes it harder to see which page, partner, or campaign brought in the visit, reducing SEO clarity and making traffic look organic or type-in.
Backlink tools like Ahrefs and Semrush also rely on seeing referrers. With noreferrer in place, they might report fewer links. This can make it harder to understand the google algorithm’s effects and evaluate nofollow links in outreach.
Keeping UTM and affiliate tracking intact with rel=”noopener” only
For tracked links, use rel=”noopener” without noreferrer. This blocks reverse tabnabbing while keeping UTM tags, referrers, and most affiliate parameters intact for GA4, HubSpot, Impact, and CJ. It helps keep track of channel attribution for campaign budgets and aligns with SEO goals.
Test a few live clicks: confirm sessions stitch, last-click rules behave, and partner platforms credit sales. Watch for cookie consent flows or auto-redirects that might drop UTMs and distort website traffic reports.
Server-side redirects and link managers to retain attribution
Branded server-side redirects help manage long URLs and keep tracking stable. Use short paths like /go/tool or /r/offer with 301s to the final landing page, ensuring UTM parameters and cookies survive hops while protecting users with rel=”noopener.”
Link managers such as Pretty Links, ThirstyAffiliates, and PixelMe can add UTMs, log clicks, and centralize updates. After changes, validate conversions end to end so that the data you trust for SEO matches what the google algorithm rewards and how nofollow links appear in reports.
| Scenario | Recommended Attribute | Analytics Impact | SEO/Link Equity | Notes |
|---|---|---|---|---|
| Affiliate or UTM-tracked outbound link | rel=”noopener” | Referrer and UTMs preserved in GA4 and partner dashboards | No change to PageRank flow; use nofollow links if policy requires | Best for accurate payouts and clean website traffic attribution |
| Privacy-sensitive outbound link | rel=”noopener noreferrer” | Traffic may shift to “Direct”; limited source visibility | Does not block crawling; consider nofollow links only if needed | Use when user privacy outweighs reporting needs |
| Branded redirect (/go/tool) | rel=”noopener” on the outbound; 301 server redirect | UTMs and referrers retained through hop | Stable for SEO auditing | Manage with Pretty Links, ThirstyAffiliates, or PixelMe |
| Editorial external citation | rel=”noopener”; optionally nofollow links per policy | Referral preserved for GA4 and backlink tools | Supports natural link signals | Avoid noreferrer if you need reporting on partner impact |
Security use cases by industry: SaaS, ecommerce, and fintech
Different industries face unique risks when opening links in new tabs. Using seo best practices helps protect users and supports search engine optimization. The right approach shields sessions, keeps data safe, and prevents revenue loss.
SaaS dashboards and docs: prioritize rel=”noopener” for session safety
SaaS products often open new tabs for documentation and support. Use rel=”noopener” to block reverse tabnabbing and keep session tokens safe. This helps with search engine optimization without changing referral data that partners need.
eCommerce checkout and payment processors: test before using noreferrer
Retail sites need accurate referral tracking for affiliates and campaigns. Avoid rel=”noreferrer” on outbound links to prevent missed attribution and chargebacks. Before adding noreferrer, test with providers like Stripe and Klarna, as it can affect reporting and website ranking.
Fintech links: using both attributes where privacy and security outweigh tracking
In banking, security and privacy are key. Use rel=”noopener noreferrer” on sensitive flows and account tools. This reduces referrer exposure and blocks tab attacks, aligning with seo best practices when trust is crucial.
Across sectors, external editorial resources can safely use rel=”noopener”. Add rel=”noreferrer” when privacy is more important than analytics and partner tracking.
Google algorithm considerations and link equity
Links are still important for how Google sees a site’s authority and trust. Using attributes wisely helps protect users and keeps link equity alive. The goal is to keep a steady ranking without breaking SEO rules or losing clarity in analytics.
Noreferrer does not block PageRank or crawling
Adding rel=”noreferrer” doesn’t stop PageRank from passing through. Google can still find and crawl the page. You can also use rel=”noopener” to ensure new tabs open safely and keep link equity strong. This choice might hide some analytics and tool visibility, but it won’t affect ranking.
Nofollow as a signal not to pass PageRank
Use nofollow for sponsored, UGC, or untrusted links. It tells search engines not to pass PageRank. This follows SEO policy and keeps risks low. Use it only when you don’t endorse the link.
Implications for link building and website traffic
For outreach, ask partners to skip noreferrer if you use backlink tools. Google can still count the link. Some referrals might show as Direct in reports with noreferrer. This impacts how you measure campaigns and predict website traffic and ranking.
Open external links safely with noopener to protect users without losing SEO. Use nofollow only when you can’t trust the link. These choices help keep link equity while supporting clean SEO and reliable measurement.
Common mistakes that hurt SEO and revenue
Small link decisions can slow website traffic and chip away at revenue. Follow seo best practices for every link attribute. This keeps tracking, equity, and UX intact.
Applying noreferrer to affiliate links, causing lost commissions
Adding rel=”noreferrer” to Amazon Associates, PartnerStack, or Impact links can strip the referrer. This breaks attribution and may void payouts.
Use rel=”noopener” only, unless the network confirms otherwise. Check program docs, run test orders, and verify conversion logs. This ensures the link attribute supports both security and website traffic.
Adding noopener/noreferrer to internal links and navigation
Internal menus, CTAs, and breadcrumbs do not need these attributes. They add noise, confuse crawlers, and disrupt analytics flows.
Remove them from in-site paths. Keep architecture clear, pass context, and protect session data without extra flags. This aligns with seo best practices and keeps website traffic signals clean.
Relying blindly on CMS defaults without auditing
WordPress often adds rel=”noopener noreferrer” when links open in a new tab. Wix may add noreferrer by default. Shopify, Webflow, and Squarespace differ by theme and app.
Run a crawl with Screaming Frog, review templates, and override where needed. Confirm how each link attribute behaves. This ensures tracking stays accurate and website traffic is measured correctly.
Actionable checklist: seo best practices for link attributes
This quick checklist helps teams apply the right link attribute in real projects. It balances search engine optimization with user safety and data integrity. It also keeps nofollow links, privacy, and tracking in sync.
When to use rel=”nofollow”, rel=”noopener”, and rel=”noreferrer”
- Always add rel=”noopener” to external links that open in a new tab to prevent reverse tabnabbing.
- Use rel=”noreferrer” only when privacy is more important than referral data, such as sensitive fintech or healthcare exits.
- Apply rel=”nofollow” to untrusted, sponsored, or UGC links; use rel=”sponsored” or rel=”ugc” where relevant.
- Avoid adding these attributes to internal links to preserve crawl paths and search engine optimization signals.
Configuring attributes per link type: external, affiliate, sponsored, internal
| Link Type | Primary Goal | Recommended Attribute(s) | Why It Works | Notes |
|---|---|---|---|---|
| External editorial (new tab) | Security + SEO | rel=”noopener” (noreferrer optional) | Stops window.opener risks while protecting search engine optimization | Add noreferrer only if privacy is required |
| Affiliate/tracked | Attribution | rel=”noopener” | Keeps tracking IDs intact and supports reporting | Avoid noreferrer to preserve referral data |
| Sponsored/UGC | Compliance | rel=”nofollow noopener” (add sponsored/ugc as needed) | Flags nofollow links and secures the tab | Add noreferrer when privacy is a must |
| Internal navigation | Architecture | No noopener/noreferrer | Maintains clear crawl paths and ranking signals | Use clean anchors and consistent site structure |
Ongoing monitoring: analytics validation and backlink visibility
- Run sitewide crawls with Screaming Frog to verify each link attribute at scale.
- Validate GA4 referral and campaign data after changes; confirm affiliate platform conversions.
- Use Pretty Links, PixelMe, or ThirstyAffiliates to manage redirects and protect attribution.
- Check Ahrefs and Semrush for backlink counts; remember that noreferrer can limit referrer visibility in tools while keeping search engine optimization intact.
- Review CMS defaults in WordPress, Shopify, Webflow, Wix, and Squarespace; ensure templates set the correct link attribute patterns.
Follow these steps to make seo best practices routine. Distribute nofollow links with intent, keep rel rules consistent, and document exceptions for teams and vendors.

It signals that PageRank should not be passed. Use it for sponsored, UGC, or untrusted links to manage link equity and comply with policies.
How do these choices impact link building and traffic?
Noreferrer can hide links from some tools, making campaigns look weaker than they are. Nofollow shapes link equity. Smart use preserves website ranking and clean referral data.
How can noreferrer hurt revenue on affiliate programs?
It can strip referrers, risking missed commissions with networks like Amazon Associates, PartnerStack, and Impact. Use rel=”noopener” instead and confirm program requirements.
Why is adding noopener/noreferrer to internal links a mistake?
It adds no security benefit internally and can confuse analytics, user flows, and site architecture relied on by the Google algorithm for context.
Why shouldn’t I rely blindly on CMS defaults?
Defaults vary and can insert noreferrer where it harms tracking. Audit regularly and adjust templates to align with seo best practices and accurate reporting.
When should I use rel=”nofollow”, rel=”noopener”, and rel=”noreferrer”?
External new tabs: always noopener. Sponsored/UGC: add nofollow. Noreferrer only when privacy is needed more than analytics or referral data.
How do I configure attributes by link type?
Editorial external: rel=”noopener”. Affiliate/tracked: rel=”noopener” only. Sponsored/UGC: rel=”nofollow noopener”. Internal: no noopener or noreferrer.
