How to Use Nofollow Tags to Combat Comment Spam

Are you tired of dealing with pesky comment spam on your website? Well, look no further! In this article, we’ll show you how to effectively use nofollow tags to combat comment spam. You may be wondering, what are nofollow tags and why are they important? Don’t worry, we’ve got you covered. We’ll explain everything you need to know about implementing and utilising these tags on your website. So let’s dive in and put an end to comment spam once and for all!

Understanding Nofollow Tags

Understanding nofollow tags is crucial in order to effectively combat comment spam. When you allow comments on your website or blog, you open yourself up to the risk of receiving spam and irrelevant comments. These comments not only clutter your platform but can also harm your website’s reputation and SEO ranking. This is where nofollow tags come into play.

Nofollow tags are HTML attributes that can be added to links within the comment section of your website. By adding a nofollow tag to a link, you are essentially telling search engines not to follow that particular link when crawling your site. This means that any potential SEO value that might have been passed through that link will be negated.

By using nofollow tags on comment links, you can prevent spammers from taking advantage of your platform for their own gain. Search engine algorithms recognise these tags and understand that they should not give any importance or credibility to those links. This helps in maintaining the integrity of your website’s content and prevents it from being associated with low-quality or malicious sites.

It is important to note that while using nofollow tags can effectively combat comment spam, it does not completely eliminate the problem. It is still necessary to have other measures in place, such as moderation filters and captchas, to ensure maximum protection against spam comments.

Importance of Nofollow Tags in Combating Comment Spam

Nofollow Tags

To effectively tackle the issue of spam in comments, you should consider the significance of implementing nofollow tags. Nofollow tags play a crucial role in combating comment spam by preventing search engines from following links posted in the comments section of your website. This means that when spammers try to leave their links on your site, those links won’t contribute to their search engine rankings.

By using nofollow tags, you can protect the integrity and quality of your website’s content. Comment spam can be harmful not only because it clutters up your comments section with irrelevant and potentially malicious links but also because it can negatively impact your website’s reputation and search engine ranking.

Implementing nofollow tags sends a signal to search engines that these links are not endorsed or approved by you. It helps prevent search engines from associating your website with low-quality or spammy content. By doing so, you maintain control over which websites are associated with yours and ensure that only high-quality and relevant sites receive any SEO benefits from linking to yours.

Moreover, using nofollow tags discourages spammers from targeting your website for backlinks as they won’t gain any SEO advantage from doing so. This reduces the number of spam comments you have to deal with and saves you time moderating them.

How to Implement Nofollow Tags on Your Website

When adding links to your website, make sure you include the rel=’nofollow’ attribute to prevent search engines from following them. Implementing nofollow tags on your website is an important step in combating comment spam and ensuring that your site remains free from malicious links. By using the rel=’nofollow’ attribute, you can signal to search engines that certain links should not be given any SEO value.

To implement nofollow tags, simply add the rel=’nofollow’ attribute to the HTML code of the link. For example, if you have a comment section on your website where users can leave their website URLs, it is crucial to mark those links as nofollow. This prevents spammers from taking advantage of your site’s authority and helps maintain its credibility.

Another important aspect of implementing nofollow tags is when dealing with user-generated content. If you allow users to post content or comments on your website, it’s essential to automatically assign the nofollow attribute to all external links within those posts. This ensures that any potential spammy or low-quality links are not given any SEO value by search engines.

Additionally, if you have sponsored content or advertisements on your site, it’s best practice to use nofollow tags for these as well. By doing so, you are transparently signalling that these are paid placements rather than organic endorsements.

Best Practices for Using Nofollow Tags

One of the best practices for implementing nofollow tags is to mark all sponsored content and advertisements as such. This helps search engines understand that these links should not pass on any link equity or authority. By clearly indicating which links are sponsored or ads, you can ensure that your website remains in compliance with search engine guidelines.

When it comes to marking sponsored content and advertisements, it’s important to use the appropriate HTML attributes. The rel=”nofollow” attribute is commonly used to indicate that a link should not be followed by search engine crawlers. Additionally, you can use the rel=”sponsored” attribute to specifically identify links that are paid placements or advertisements.

Another good practice is to include a disclaimer on your website stating that some of the links may be affiliate links or sponsored content. This transparency builds trust with your audience and ensures that they are aware of any affiliations or partnerships you may have.

It’s also worth mentioning that while nofollow tags can help combat comment spam, they are not a foolproof solution. Implementing other measures like CAPTCHA verification, moderation systems, and spam filters can further enhance your ability to manage and prevent spam comments on your website.

Common Mistakes to Avoid With Nofollow Tags

Make sure you are aware of the common mistakes to avoid when implementing nofollow tags on your website. Nofollow tags are a great tool to combat comment spam and protect your website’s SEO. However, if not used correctly, they can hinder your site’s performance and even lead to penalties from search engines. So, here are some common mistakes you should be careful to avoid.

Firstly, one mistake is applying nofollow tags too broadly. Remember that the purpose of these tags is to tell search engines not to follow certain links, such as those in user-generated content or paid advertisements. But if you apply them indiscriminately across all your internal links or even external links, it can harm your site’s overall SEO efforts. Only use nofollow tags where necessary.

Secondly, another mistake is forgetting to regularly review and update your nofollow tag implementation. Over time, the structure of your website may change with new pages being added or old ones being removed. If you fail to update your nofollow tags accordingly, it can result in broken or unnecessary links being labelled as “nofollow,” which can confuse search engine crawlers.

Lastly, don’t forget about internal linking when implementing nofollow tags. Internal linking plays a crucial role in improving site navigation and distributing link authority throughout your web pages. However, mistakenly using nofollow tags on internal links can disrupt this flow and prevent search engines from properly indexing and ranking your content.

Effective Strategies for Dealing With Comment Spam

Now that you know the common mistakes to avoid with nofollow tags, let’s talk about effective strategies for dealing with comment spam. Comment spam can be a major headache, but with the right approach, you can minimise its impact on your website.

First and foremost, make sure you have a reliable spam filter in place. This will automatically detect and block most spam comments before they even reach your moderation queue. There are several plugins available for popular content management systems like WordPress that can help you with this.

Another strategy is to moderate all comments manually. While this may require more time and effort on your part, it allows you to personally review every comment before it goes live on your website. Look out for suspicious links or overly promotional content and delete any comments that don’t contribute value to the discussion.

Consider implementing a user registration system. By requiring users to create an account before they can leave a comment, you deter many automated spammers who prefer easy targets. Additionally, registered users are less likely to engage in spammy behaviour since their identity is tied to their comments.

Regularly monitor your comment section and respond promptly to legitimate comments. This not only encourages genuine engagement but also sends a message that you actively manage your website and won’t tolerate spammy behaviour.

Lastly, consider using tools like Akismet or Disqus as they offer additional features such as reputation systems and community moderation options that can further help combat comment spam effectively.

Nofollow Vs. Dofollow: Which Is Better for Combatting Comment Spam

When it comes to dealing with spam in comments, the choice between nofollow and dofollow links is an important consideration. So, what exactly are these links and which one should you use? Let’s break it down.

Nofollow links are a way of telling search engines not to follow a particular link. This means that if someone leaves a spam comment with a link on your website, search engines won’t give any SEO value to that link. In other words, nofollow links don’t pass on any “link juice” or authority from your website to the linked page. This can be an effective strategy for combating comment spam because it discourages spammers from leaving their links in the first place.

On the other hand, dofollow links allow search engines to follow them and pass on SEO value to the linked page. While this may seem like a good thing for legitimate commenters who leave valuable links, it also opens up an opportunity for spammers to take advantage of your website’s authority by leaving their own links.

So which one should you choose? Well, there isn’t a definitive answer. It depends on your specific situation and goals. If you’re concerned about comment spam and want to minimise its impact on your SEO efforts, using nofollow links is generally recommended. However, if you trust your commenters and want to encourage genuine engagement by allowing valuable backlinks, then dofollow might be a better option for you.

Tools and Plugins to Simplify Nofollow Tag Implementation

To simplify the implementation of nofollow tags, you can try using various tools and plugins available. These tools are designed to make your life easier and save you time in adding nofollow attributes to your website’s links. One popular tool is the “Nofollow Checkbox” plugin, which adds a simple checkbox option to your post editor. This allows you to easily mark specific links as nofollow with just a click of a button.

Another useful tool is the “Nofollow External Links” plugin, which automatically adds the rel=”nofollow” attribute to all external links on your site. This eliminates the need for manual tagging and ensures that any outgoing links from your website won’t pass on link juice or be targeted by comment spam.

If you’re using WordPress as your content management system, there are several plugins available specifically for simplifying nofollow tag implementation. One such plugin is “Ultimate Nofollow,” which provides an intuitive interface where you can easily add or remove nofollow attributes from individual links.

For those who prefer a more hands-on approach, there are also online tools like “Nofollow Link Checker” that allow you to analyse your website’s links and identify any missing or incorrect nofollow tags. This way, you can quickly fix any issues and ensure that all external links are properly marked.

Analysing the Impact of Nofollow Tags on Comment Spam

Using tools and plugins to simplify nofollow tag implementation can help reduce the impact of comment spam on your website. By utilising these resources, you can effectively analyse the impact of nofollow tags on comment spam and take appropriate measures to combat it.

One way to analyse the impact is by using analytics tools that provide insights into your website’s traffic and user behaviour. These tools can help you identify patterns in comment spam, such as common keywords or URLs used by spammers. Armed with this information, you can then implement nofollow tags strategically to deter spammers from targeting your site.

Additionally, there are plugins available that automatically add nofollow tags to all external links in comments. These plugins make it easy for you to implement the necessary code without manually editing each individual comment. This saves you time and ensures consistent application of nofollow tags across your entire website.

Another aspect to consider is monitoring user-generated content on your site. Implementing a moderation system or using anti-spam filters can help prevent spam comments from being published in the first place. By actively monitoring and filtering comments, you can drastically reduce the amount of spam that makes its way onto your site.

It’s important to remember that while nofollow tags may not completely eliminate comment spam, they serve as an effective deterrent. By making it clear to spammers that their efforts will not result in improved search engine rankings or increased visibility, they are less likely to target your site.

Long-term Benefits of Using Nofollow Tags in Your Comment Section

Implementing nofollow tags in your comment section can have long-term benefits for maintaining a clean and reputable online presence. By using these tags, you are effectively signalling to search engines that any links within the comments should not be given any value or ranking authority. This means that spammers who are looking to promote their own websites or products through your comment section will no longer be able to benefit from the SEO value of those links.

One of the key advantages of using nofollow tags is that it helps prevent comment spam. Comment spam refers to irrelevant or inappropriate comments left by automated bots or individuals who are looking to exploit your website’s traffic for their own gain. These spam comments often contain links to low-quality or malicious websites, which can harm your site’s reputation and even lead to penalties from search engines.

By implementing nofollow tags, you can deter spammers from targeting your comment section as they know that their efforts will not result in any SEO benefits. This reduces the amount of time and effort you need to spend on moderating and cleaning up spam comments, allowing you to focus on more important tasks related to managing your online presence.

Furthermore, using nofollow tags also helps protect the user experience on your website. When visitors see a lot of spammy or irrelevant comments with links, it can lower their trust in your brand and discourage them from engaging with your content. By ensuring that all outbound links in comments are marked as nofollow, you can maintain a clean and trustworthy environment for both users and search engines.


In conclusion, using nofollow tags is an effective way to combat comment spam on your website. By implementing these tags correctly, you can prevent search engines from following spammy links and improve the overall quality of your comment section. Remember to follow best practices and avoid common mistakes when using nofollow tags. While both nofollow and dofollow have their benefits, nofollow is generally preferred for combatting comment spam. Additionally, there are various tools and plugins available to simplify the implementation of nofollow tags. Embracing this technique can yield long-term benefits for maintaining a clean and engaging comment section on your website.
