Hi, This is for those who might be banned by google as you know it holds around 90% of internet search as of today.
Common ways of getting banned from Google.
Hidden text or hidden links – when you think about how this is done (making the color of the text the same color as the background that it’s placed over, how hard would this really be for Google to detect with a small piece of code in their algorithm?
Use of cloaking or sneaky redirects – and yes, Google calls them “sneaky.”
Loading pages with irrelevant keywords – aka keyword stuffing.
Creating multiple pages, subdomains, or domains with substantially duplicate content.
Creating pages with malicious behavior, such as phishing or installing viruses, trojans, or other mal-ware.
Producing “Doorway” pages created just for search engines with little or no original content. The key to this is “little or no original content.” If you’re actually adding new content to the web then this shouldn’t be a problem.
There are also some “back-door” ways of getting your site banned from Google, such as including several links to sites that are known for spamming, thus causing Google to draw the conclusion that you’re affiliated with them.
