9 Common Dofollow and Nofollow Link Mistakes That Hurt SEO
A website can have hundreds of backlinks, a carefully planned internal linking structure, and regularly updated content—yet still contain link attribute errors that go unnoticed.
Some errors create genuine SEO risks. Others lead teams to make unnecessary changes because they misunderstand how Google interprets links.
For example, a paid placement without appropriate qualification raises a different concern from an editorial link marked nofollow. One involves Google’s link-spam policies; the other may simply reflect a publisher’s linking decision.
The challenge is knowing which issues require immediate correction, which need investigation, and which aren’t problems at all.
Here are nine common dofollow and nofollow link mistakes, with practical examples and specific fixes for SEO teams, publishers, and link builders.
Which Dofollow and Nofollow Link Mistakes Should You Fix First?
Not every unusual link attribute deserves the same attention.
Start by separating compliance issues from technical implementation errors and misleading backlink reports.
| Issue | What can go wrong | Priority |
| Unqualified paid links | Link-spam policy risk | High |
| Important internal links marked nofollow | Weaker link-based discovery signals | High when widespread |
| Nofollow used as an indexing control | Pages may remain indexed | High if indexing must be prevented |
| Missing UGC qualification | User-submitted links may create spam exposure | Medium–High |
| Incorrect plugin-generated attributes | Errors repeated across many pages | Depends on affected links |
| Backlink reports based only on follow status | Misleading campaign decisions | Medium |
Before changing anything, inspect the published HTML rather than relying on a spreadsheet label or publisher’s confirmation.
A Dofollow Nofollow Tool can help review hyperlink attributes on supplied source pages, including whether links carry nofollow, sponsored, or ugc.
Use the findings to identify what needs investigation—not as an automatic instruction to change every nofollow link.
1. Leaving Paid or Sponsored Links as Regular Followed Links
This is one of the more consequential link attribute mistakes because it can involve Google’s link-spam policies.
A Realistic Scenario
A company pays a publisher to feature its product in an article. The publisher includes a standard hyperlink:
<a href=”https://brand.example/product”>
Explore the Product
</a>
The link has no qualifying attribute, even though compensation influenced its placement.
Google’s spam policies address buying or selling links for ranking purposes. Paid links should be appropriately qualified rather than presented as ordinary editorial endorsements.
What to Do Instead
For sponsored placements, Google prefers rel=”sponsored”:
<a href=”https://brand.example/product”
rel=”sponsored”>
Explore the Product
</a>
Google also accepts rel=”nofollow” for paid links.
Practical checks:
- Compare sponsored-content agreements against published hyperlinks.
- Review affiliate modules and advertising templates.
- Confirm that qualification appears in the live HTML, not just the CMS editor.
Key distinction: A paid article isn’t automatically a problem. The concern is using compensated links to manipulate search rankings without appropriate qualification.
2. Adding Nofollow to Important Internal Links
Internal links help users navigate a website and help search engines discover connected content.
Unnecessary nofollow attributes can interfere with the normal link signals you intend to provide.
Example: A Navigation Template Error
Imagine a service website with an important category page linked from its main navigation:
<a href=”/services/” rel=”nofollow”>
Our Services
</a>
The attribute may have been added accidentally through a theme setting or migration.
If the page is intended to be accessible and discoverable, that qualification is usually unnecessary.
How to Fix It
Replace the link with a standard crawlable hyperlink:
<a href=”/services/”>
Our Services
</a>
Before editing individual pages, determine where the attribute originates.
| Where the issue appears | First place to investigate |
| Main navigation | Theme or navigation component |
| All blog posts | Article template |
| Related-post widgets | Widget or plugin settings |
| Selected editorial links | CMS link settings |
A shared template fix can resolve the same mistake across hundreds of URLs.
Don’t assume every internal nofollow causes a measurable ranking decline. Prioritize important navigation paths and widespread implementation errors.
3. Using Nofollow When You Actually Need Noindex
Nofollow and noindex solve different problems.
A nofollow attribute applies to a hyperlink. A noindex directive applies to a page’s eligibility for indexing.
Confusing them can leave unwanted pages appearing in search results.
The Mistake
An SEO manager wants to prevent an internal search-results page from being indexed.
Instead of adding a page-level directive, the team applies nofollow to links pointing to it.
That doesn’t reliably prevent Google from discovering or indexing the destination through other routes.
Use the Correct Control
| Objective | Appropriate mechanism |
| Qualify a hyperlink relationship | rel=”nofollow” |
| Prevent an accessible page from being indexed | Meta robots or X-Robots-Tag noindex |
| Restrict crawler access to a URL path | Robots.txt |
| Indicate a preferred duplicate URL | Canonical link element |
For a page that should not be indexed, a common implementation is:
<meta name=”robots” content=”noindex”>
Google must be able to crawl the page to see this directive.
Blocking the same URL in robots.txt can prevent Google from accessing its noindex instruction.
Practical takeaway: Define whether the problem concerns a link, crawling, or indexing before choosing a technical solution.
4. Automatically Nofollowing Every External Link
Some websites apply rel=”nofollow” to every outbound hyperlink because they believe linking externally will weaken their SEO.
That is not how Google recommends handling ordinary editorial references.
Where This Goes Wrong
Consider an article explaining Core Web Vitals that links to Google’s official documentation.
The citation exists to support the article and help readers verify the information.
Applying nofollow automatically doesn’t reflect a specific concern about endorsement, compensation, or user-generated content.
A Better Editorial Rule
Evaluate external links according to their purpose.
- Editorial citation: A regular hyperlink is generally appropriate.
- Paid recommendation: Use appropriate sponsored-link qualification.
- Unendorsed reference: Consider nofollow.
- User-submitted link: Consider ugc.
Avoid setting an arbitrary maximum number of followed outbound links or automatically qualifying every external destination.
5. Ignoring Sponsored and UGC Link Attributes
A binary dofollow-versus-nofollow report doesn’t always provide enough information for a publisher’s compliance review.
Google supports more specific relationship values.
| Attribute | What it communicates | Typical placement |
| nofollow | No normal editorial endorsement intended | Unendorsed references |
| sponsored | Advertising or compensation relationship | Paid placements and affiliate links |
| ugc | User-generated content | Comments and forum posts |
Example: A Forum Link
A user posts an external URL in a public discussion.
The platform should distinguish that user-submitted link from an editorial reference created by the publisher.
<a href=”https://example.com/”
rel=”ugc”>
Shared Resource
</a>
Google also supports combined attributes:
<a href=”https://example.com/”
rel=”ugc nofollow”>
Shared Resource
</a>
What to Check
Review the systems generating these links, especially:
- Comment plugins and community platforms.
- Affiliate link-management tools.
- Sponsored-content templates.
Using nofollow for every qualified link isn’t automatically a violation. Google accepts nofollow in several situations.
The improvement is accurately representing the relationship where more specific attributes are appropriate, not changing attributes merely for appearance.
6. Treating Every Dofollow Backlink as Valuable
A followed link is eligible for consideration by Google’s ranking systems.
It is not a certificate of quality.
Consider These Two Backlinks
| Backlink A | Backlink B |
| Appears in a relevant industry article | Appears in unrelated, thin content |
| Supports a genuine editorial reference | Uses an awkward keyword-stuffed anchor |
| Helps readers find supporting information | Exists primarily for link placement |
| Regular followed link | Regular followed link |
Both may be technically followed, but their editorial context differs substantially.
Google doesn’t disclose the ranking value assigned to individual backlinks. Therefore, counting followed links alone cannot establish a campaign’s SEO impact.
Improve Your Backlink Evaluation
Review:
- Topical relevance: Does the source page relate meaningfully to the destination?
- Placement context: Is the link useful within the surrounding content?
- Editorial purpose: Was it included for readers or primarily to influence rankings?
- Spam indicators: Does the placement resemble a manipulative link scheme?
For reporting, separate technical verification from quality assessment.
A backlink can pass a follow-status check while still requiring editorial review.
7. Checking Only Source HTML on JavaScript-Heavy Websites
Modern websites may modify hyperlinks after the initial HTML response loads.
A checker that reads only the original document can therefore produce a different result from an inspection of the rendered page.
Example: A JavaScript-Generated Link
The initial HTML might contain a placeholder:
<div id=”related-resource”></div>
JavaScript later inserts:
<a href=”/resources/”>
Related Resources
</a>
If an audit examines only the original response, it may miss the link entirely.
A similar issue occurs when scripts modify href or rel values after page load.
How to Investigate a Mismatch
- Open the published page in a browser.
- Inspect the link in the rendered DOM.
- Compare its destination and attributes with the initial HTML.
- Check whether the link appears only after a user interaction.
- Record which version your auditing tool examined.
For critical SEO links, use crawlable anchor elements with valid href destinations.
Important: Google’s ability to render JavaScript doesn’t guarantee that every JavaScript-dependent interaction will be processed as intended.

8. Overlooking Attributes Added by CMS Plugins and Templates
An editor may insert a regular hyperlink, but the published HTML can contain additional attributes introduced elsewhere in the website’s technology stack.
This is especially relevant to websites using affiliate plugins, page builders, reusable content blocks, and custom themes.
Example: An Affiliate Plugin Rule
A content team selects sponsored for compensated links.
Later, a plugin update changes the output to a different attribute configuration.
The editor interface may still look correct, while the live page behaves differently.
Troubleshoot the Actual Source
| Symptom | Likely investigation area |
| All affiliate links share an unexpected attribute | Affiliate plugin settings |
| Navigation links change after redesign | Theme templates |
| Only mobile links differ | Responsive components |
| Attributes disappear after publishing | CMS sanitization or content filters |
| Initial and rendered HTML disagree | JavaScript modifications |
Prevent Recurring Errors
Add link-attribute checks to release testing whenever plugins, templates, or content-rendering systems change.
Test representative page types rather than relying on a single homepage scan.
The goal is to correct the system producing the mistake, not repeatedly repair individual hyperlinks.
9. Never Rechecking Backlinks After Publication
Backlink verification is often treated as a one-time task.
An outreach team confirms a placement, marks it complete, and moves on.
But published pages can change.
A publisher may update the article, change its URL, remove a link, introduce a redirect, or modify the link’s attributes.
What a Useful Verification Record Includes
| Field | Example |
| Source page | Published guest-post URL |
| Expected destination | Agreed landing page |
| Anchor text | Published anchor |
| Link attribute | Followed, nofollow, sponsored, or UGC |
| Last checked | Verification date |
| Current status | Confirmed / changed / needs review |
This record helps distinguish a genuine placement change from an outdated campaign report.
When to Recheck
Focus on meaningful triggers rather than checking every link daily.
Reverification is useful after publisher migrations, significant article updates, unexpected destination changes, or before delivering an important campaign report.
If a placement changes, confirm the live HTML and any redirects before contacting the publisher.
A Practical Framework for Prioritizing Link Fixes
After identifying mistakes, classify them by risk, scale, and ownership.
| Priority | Example | First action |
| Critical review | Paid links used to manipulate rankings without qualification | Investigate and correct the commercial-link implementation |
| High | Important internal navigation unintentionally nofollowed sitewide | Fix the shared component |
| High | Sensitive pages indexed because nofollow was mistaken for noindex | Implement the appropriate indexing directive |
| Medium | UGC links missing intended attributes | Correct platform rules |
| Medium | Plugin update changes link attributes | Test and restore expected output |
| Routine | Older backlink placements need confirmation | Schedule checks based on campaign importance |
A useful remediation record should identify the affected pages, root cause, responsible owner, proposed fix, and verification result.
Don’t automatically change every link flagged by a tool. Confirm whether the attribute is actually incorrect for that link’s relationship.
Frequently Asked Questions
Can Nofollow Links Hurt SEO?
Nofollow links aren’t inherently harmful. They can be appropriate for unendorsed, sponsored, or user-generated links. Problems arise when attributes are misused or when teams mistake nofollow for an indexing-control mechanism.
Is Having Too Many Nofollow Backlinks Bad?
Google doesn’t prescribe an ideal followed-to-nofollow backlink ratio. A high number of nofollow links isn’t automatically evidence of a problem. Evaluate the sources and context instead.
Should Every Paid Link Use Sponsored?
Google recommends rel=”sponsored” for advertising and compensated placements and also accepts nofollow. Paid links intended to manipulate rankings without appropriate qualification can violate Google’s spam policies.
Does Adding Rel=”dofollow” Improve Rankings?
No. Standard followed hyperlinks don’t require a dofollow attribute. Adding rel=”dofollow” doesn’t create an extra ranking benefit.
Can SEO Plugins Change Link Attributes Automatically?
Yes. Depending on their settings, plugins and templates can add or modify link attributes. Inspect the published HTML after configuration changes or software updates.
