Comment spam is an automated attack where malicious users exploit a site’s comment fields to post irrelevant, low-quality messages or unrelated URLs. This not only clutters your site but can also have serious repercussions for your website’s performance and reputation. Here’s a comprehensive look at comment spam, its goals, characteristics, and how to protect your site.
What Is Comment Spam?
Comment spam refers to the practice of posting unsolicited and irrelevant content in a site’s comment sections. Often carried out by automated bots, these spam comments can include promotional material, dubious links, or other disruptive content. The goal is usually to drive traffic to external sites, manipulate search engine rankings, or spread spam.
Goals of Comment Spam
- Advertising and Promotion
- Product Promotion: Spammers use comments to promote products or services, hoping to attract new customers.
- Blog or Website Promotion: They often include links to their own blogs or websites to boost their visibility.
- Affiliate Codes: Trying to promote an affiliate code where they receive a commission
- SEO Manipulation
- Backlinking: By embedding links in your comment sections, spammers aim to leverage your site’s authority to improve their own search engine rankings.
- Spreading Spam
- Sending Spam to Other Recipients: Some comments are used as a vector to distribute spam or malware to unsuspecting visitors.
Characteristics of Spam Comments
