SEO Cloaking With Example

Here is a simple example that gives you a clear understanding of content cloaking 

Let us assume you are the owner of a website that sells various baby products including the best skincare products. 

Now, when people search for the “best baby skincare products” you like your website to show up higher in search results.

There are many SEO techniques to rank your website for a particular keyword but with this SEO cloaking practice, you can create a dynamic optimized version of your website for search engines like Google and Bing and another basic version for regular visitors.

Here’s how it works:

  • When Google’s bot (also called a spider or crawler) visits your site to crawl, your website shows a special optimized page about “best baby skincare products” This page has optimized content and keywords related to the best baby skincare products you sell. 
  • When a regular person other than crawlers visits your website, your site shows a homepage with all your baby products, including haircare and medicare products.

So, in simpler terms, you are trying to serve Google with a page optimized to rank high for “best baby skincare products,” while regular visitors see your basic website.

But, remember, Google doesn’t like this, Now there are enhanced algorithms to find it,  If Google finds out you’re showing them one thing and visitors another, they might penalize your site, or even get removed from the search results page.

Types of Cloaking Practices:

Let’s discuss some types of cloaking practices 

  • IP-based Cloaking:

In this type, the server shows up the website based on the IP address of the visitor. For example, content versions vary based on geographic locations, and a completely different version is shown to others.

  • User-Agent Cloaking:  

User-agent cloaking involves serving particular content based on the user-agent string sent by the visitor’s browser. Different versions of the page might be served to different browsers or devices.

  • JavaScript Cloaking: 

In this type of cloaking, the content displayed to the user depends on whether JavaScript is enabled or disabled in their browser. This can be used to hide content from search engines that cannot execute JavaScript when crawling the site.

  • Cookie-based Cloaking:

Content is customized based on certain cookies in the visitor’s browser. This can be used to customize content for users who have previously visited the site

  • Referrer-based Cloaking: 

In this, content is served to users based on the referring website or URL that the visitor came from. Different content is shown to visitors who click on a link from a search engine, social media site, or another referring site.

  • Session-Based Cloaking: 

This involves showing different content to users based on their session ID. This can be used to personalize the user’s content, but it can also be used to cloak content from search engines.

Even though some cloaking practices are practiced for good user experience, it is harmful to your website if used in an unethical manner.

Just learn how website users implement content cloaking and it is not recommended to use it in your content.
