What is a Spam Link?
Spam links are links inserted into a website with the intent of manipulating search engine result pages. The more inbound links a site receives, the higher the placement of the target web site in the search results. Spam links are typically inserted into the database content in plain text, though they can also often be obfuscated (intentionally obscured to make code ambiguous) and inserted into site files.

- Pharmaceutical sales
- Essay writing sites
- Ringtones and music downloads
- Movie downloads
- Online casino or gambling
- Fraudulent/replica designer sales
- Weight loss supplements or products

Finding and Removing Spam Links
Removing spam links requires analysis of the site’s code and database. First, make a backup of your site’s files and database.
Reviewing files for spam links
Often spam links will be hidden using styles that hide the links from visibility within the page, such as:
<div style="position: absolute; top: -132px; overflow: auto; width:1259px;">
Reviewing the database for spam links
Removing spam links from the database can be time consuming. Often, spam links will be inserted by a script that changes the links just enough to be different every time. If you have this type of spam link, you will often have thousands of links on your site.
Removing these links: To remove these links, there are a few options. Often, these links are inserted into every post on the site. Scripts can be removed by editing:
- within the content management system (e.g., via WordPress post editing)
- via a database tool like PhpMyAdmin which allows for editing more than one page/post at a time.
- via a downloaded text file locally and uploading the cleaned posts into the database using a SQL management tool. While fastest, this does require a level of technical expertise in working with SQL.
Looking Beyond the Spam Links
