Certain traits can be used to identify a website user and can be in turn used to redirect them to another web page. Most of these redirects include code referral, IP address referral and user agent. It can be a legitimate and vital technique when there is a limitation of the web browser. Redirecting is also critically used when a web server uses a client IP to determine and analyze the language content of a web page. Problems arise when a site filters its data content based on browser against search engine boot. This filtering technique can run the gamut between different tasks as showing a keyword stuffed page with different web content. A web spam is an attempt to deceive and can be detected by search engines. The search engines detect the content presented by user agents. It verifies the differences between content in the same light and those that are between mobile browsers.
Some webmasters design their website to detect search engine Bot and act on it deceptively. The fist technique one can use is the script- based redirects. This uses JavaScript tags to determine which page is to be displayed. These assist to analyze sites which are suspicious to get scrutiny. The usage of JavaScript is to direct all user agents to a new page, and that newly created page might contain spam. Since search engine do not locally execute the redirect, they index the content of the original page.
The second technique is through referral redirects. The consideration of the referrer is when certain website shows a page. This identifies a web spam when a referrer is a SERP. SERP detailed demonstration is the deceitful URL loading to a site. The third technique one can use to identify spam is the redirect search engine bot. Some sites detect spam by detecting user agent. It sends search engines bot to neutralize and alternate the spam modified web pages. When filtration of these redirects is on relevant search engines, the site provides its normal web contents pages to the end user agents. Web version of cloaking happens when redirects usage is on search engine user agent with the main agenda of deceiving them. Bot can detect spam when redirected to certain pages. Technical deception implied by webmasters is not highly effective. Search engines use these techniques to uncover these practices and the perpetrators penalized severely.
