How to Create a .htaccess File to Combat Referral Spam
Overview
Referral spam is a growing issue affecting websites and blogs, causing significant disruption for users and administrators. This guide will explore what referral spam is, how it impacts websites, and practical strategies to mitigate it using a .htaccess file.
Understanding Referral Spam
Referral spam occurs when spammers exploit the HTTP referrer system, sending false information to web servers. This is done either to manipulate search engine rankings or to appear in analytic reports. Spammers can forge Referrer headers because there is no built-in authentication in HTTP protocols.
Why Referral Spam is Problematic
1. Increased Bandwidth Usage: Referral spam can generate unnecessary requests that consume bandwidth, potentially leading to higher costs.
2. Data Pollution: It clutters web analytics, making it difficult for administrators to understand genuine traffic sources.
3. Server Strain: It wastes CPU resources and disk space, adding operational strain.
Combating Referral Spam with .htaccess
Creating a .htaccess file can help block unwanted traffic. Here are some methods to enhance your site's defenses:
Block Users by Referrer
.htaccess can block traffic originating from specific domains, which is effective if there's suspicious referral activity with no legitimate links back to your site. Use the Apache mod_rewrite module to process these referrer requests.
Blacklist Referrals
You can add known spam sources to a blacklist within the .htaccess file. This approach requires regular updates because spammers often rotate domains quickly.
Access Control by IP and Domain
Use .htaccess to restrict access from known malicious IP addresses or entire domains. Specify full or partial IP addresses to block a range of IPs. Also, you can block domains by typing them without the "www" prefix.
Implementation Steps
1. Generate the Code: Use an .htaccess generator to create rules that block specific IPs, domains, or even countries.
2. Edit and Upload: If an .htaccess file already exists, append the new rules without altering existing code. Upload the updated file in ASCII mode.
3. Nofollow Attribute: Use the `rel="nofollow"` attribute for links to prevent them from influencing search engine rankings.
The Nofollow Solution
A coalition of blogging and search engine companies supports using the `rel="nofollow"` attribute to combat comment and referral spam. This attribute prevents spammers from benefiting in terms of search engine rankings.
Challenges and Considerations
Despite these measures, achieving 100% protection against referral spam is challenging. Spammers may still exploit vulnerabilities, as complete industry-wide adoption of solutions like `rel="nofollow"` is difficult.
Filtering referrer IPs against a spam blacklist can be helpful. Ensure that spam hostnames do not appear in your website stats and avoid querying these sites.
Conclusion
While referral spam poses a significant challenge, employing strategies like .htaccess modifications and using attributes like `rel="nofollow"` can substantially reduce its impact. Continuously updating your defense tactics is crucial to maintaining a clean and efficient web environment.
