2. Detection of CSS Spam

The bad thing about black hat SEO is, that some people always think they are too clever. The good thing about search engine algorithms is, that they are updated more or less regularly and that they are constantly getting better in trapping black hat SEO down. As a result many of these dark freaks find themselves or their websites penalized or even banned by the search engines. One of the latest search engine "tricks" had been CSS spamming. CSS spam are CSS pages which have been solely created for the misleading of both, search engine bots and human visitors. Playing such games with CSS is no longer worth the effort, at least after the recent Google Jagger Update. At least the Google robot will with a pretty good certainty detect such spam CSS leading to invisible text, which it by any means will rate as SPAM.

Solution:
Use CSS and CSS style sheets for better formatting of your website, not in order to mislead search engine robots. Besides, I can still not understand why so many webmasters are trying to hide their text away. Write good, honest content and make it officially visible to your visitors and the search engine spiders. The result is even better than spamming, because you will not mislead and will attract both, robots and humans, to rate your site to be more valuable. And all this without the constant danger of getting trapped and penalized on any other day.
