Injected content

Spammers place certain files and php scripts containing virus or malware inside your website files. This gives access to spammers to see flows of your website, attack website, shut it down, block your access, add links to your sitemap, use fishing to get details from your visitors and more.

Added content

Spammers add new pages, posts and attachments in the website. This will boost the spam website ranking in Google and reduce your ranking.

Hidden content accessed by bots

They may add hidden content inside the website files which can only be seen by bots especially Google bots, MSN bots and other search engine bots. Bots are used to crawl your website links and list them in search engines as per the ranking factors. 

You and the visitors may not notice these links or pages but bots will identify them and list them. This will reduce your website ranking and increase their ranking.

Redirects URLs

This is the most common hacked content issue in websites. Spammers put their links inside the website. When a visitor clicks a link in Google to your website, they will be automatically redirected to the spammer website. Your website lose ranking eventually and get penalized for redirects.

Cloaking and/or 301 redirects

These web pages shows one type of content for human visitors and other content for Google bots. So that when bots crawl the web page, it look like a valid page with good content. For a human visitor it may look like a websites with some not so good content. Sometimes these sites use 301 redirects to redirect human visitors to other pages and that way lead to bad web pages.

Pure spam websites

Content that copied from other websites, stuffing keywords in web pages, automatically generated content using software etc. These are easy to find out.  “Unnatural links from a site” is shown twice at the web page which is scraping content and according to Google, this is policy violation.

Websites with thin content are added for removal after pure spam websites. Websites unnatural links are added for removal are in the third place leading to hacked sites at the fourth place.
