When it comes to SEO, the role of links can’t be overstated. But not all links are created equal, and understanding the difference between nofollow links and dofollow links is essential for crafting a winning SEO strategy. In this article, we’ll dive into nofollow links SEO, exploring what they are, why they matter, and how to use them effectively to boost your website’s visibility.
What Are Nofollow Links?
In the simplest terms, a nofollow link is a hyperlink with a specific attribute (rel=”nofollow”) that tells search engines not to pass any link equity (also called “link juice”) to the linked website.
Introduced by Google in 2005, the nofollow attribute was designed to combat spammy links and excessive backlinking. While users can still click on nofollow links and visit the linked pages, search engines treat these links differently in their ranking algorithms.
Update: Google’s 2019 Link Attributes and 2020 Hint Treatment
In September 2019, Google added two rel values, rel=”sponsored” for paid links and rel=”ugc” for user-generated content. These values help label link intent more precisely than a blanket rel=”nofollow”.
For ranking purposes, Google treats rel=”nofollow”, rel=”sponsored”, and rel=”ugc” as hints, not directives. Starting March 1, 2020, this hint model also applies to crawling and indexing behavior.
You can use multiple values together when needed. For example, a paid link in an unmoderated comment can be rel=”sponsored nofollow” or rel=”ugc sponsored”.
Values are space separated. There is no required order for listing them.
Nofollow Links vs. Dofollow Links
To understand nofollow links SEO, it’s essential to grasp how they differ from dofollow links:
| Aspect | Nofollow Links | Dofollow Links |
|---|---|---|
| Purpose | Instruct search engines not to pass link equity. | Pass link equity and contribute to ranking. |
| SEO Impact | No direct impact on rankings but can drive traffic and exposure. | Positively influences rankings by boosting authority. |
| Use Cases | Paid links, affiliate links, user-generated content. | Natural backlinks from trusted sources. |
Why Are Nofollow Links Important in SEO?
While nofollow links don’t directly boost rankings, they are far from useless. Here’s why they matter in nofollow links SEO:
1. Diverse Link Profile
Search engines prefer a natural backlink profile that includes a mix of dofollow and nofollow links. Having only dofollow links can look suspicious and might raise red flags.
2. Referral Traffic
Even without passing link juice, nofollow links can drive significant traffic to your website, especially when placed on high-traffic pages.
3. Brand Exposure
Nofollow links on authoritative sites increase your brand’s visibility, helping you reach new audiences and build trust.
4. Spam Prevention
By marking certain links as nofollow, you can prevent passing authority to low-quality or untrusted sites, protecting your SEO strategy from penalties.
Common Use Cases for Nofollow Links
Use rel="sponsored" for paid placements and affiliate links, and rel="ugc" for comments, forums, and other user submissions. Combine values with spaces when a link is both untrusted and paid. Avoid using rel="nofollow" on internal navigation for PageRank sculpting, Google does not recommend this, and it does not conserve link equity or improve crawl efficiency sitewide either.
1. Paid Links
Any link that you’ve paid for should include the nofollow attribute to comply with Google’s guidelines.
2. Affiliate Links
To avoid search engines treating affiliate links as manipulative, use nofollow tags to signal that these are monetized links.
3. User-Generated Content
Links in blog comments, forums, and social media posts should often be nofollow to avoid being penalized for spammy or irrelevant links.
4. Press Releases and Sponsored Content
Google recommends using nofollow tags for links in press releases or sponsored posts to maintain transparency.
How to Use Nofollow Links in Your SEO Strategy
1. Audit Your Link Profile
Use tools like Ahrefs or SEMrush to analyze your backlinks and identify opportunities to diversify with nofollow links.
2. Focus on High-Quality Sites
When pursuing nofollow links, aim for placements on authoritative websites where your content is relevant and valuable.
3. Balance Dofollow and Nofollow Links
An ideal link profile includes a mix of both types of links. Avoid over-optimizing with only dofollow links, which could look unnatural.
4. Leverage Social Media and Directories
Many social media platforms and online directories use nofollow links. While they don’t pass link equity, they can drive traffic and build brand visibility.
Link-Level vs. Page-Level Nofollow
Link-level nofollow adds rel=”nofollow” to individual links, affecting how each link is interpreted. Page-level nofollow uses a meta robots tag or an HTTP header to suggest that crawlers should not follow any links on the page.
Both are treated as hints rather than strict rules in Google systems since 2020. Page-level nofollow does not stop the page from being indexed, use “noindex” for that outcome.
Practical Example of Nofollow Links
Imagine you write a guest post for a reputable blog, and they include a nofollow link to your homepage in your author bio. While the link won’t directly impact your SEO rankings, it could:
- Drive targeted traffic to your site.
- Introduce your brand to a new audience.
- Build your authority in the industry.
This demonstrates the indirect benefits of nofollow links SEO in a well-rounded SEO strategy.
