SEO fallacy: hidden text and unwise note

Let’s continue what should not be done in search engine ranking optimization. Here’s a website that looks good at first glance:

But if you turn off CSS, you will see something completely different:

Why is the difference so big? Let’s take a look at the corresponding part of the HTML file of the web page:

Pay attention to the green part, the meaning of translating into Chinese is: insert the text you want to hide here, don’t forget to put your keyword. Usually I don’t recommend people to use CSS to hide text. I don’t recommend anyone to put the note there too.

My comment: All search engines have always used hidden text or hidden links as a means of cheating. If you find such a website that uses hidden text, you will be punished and even de listed.

Most of the early hidden texts used words of the same colour as the background colour. For example, put a white word on a white background so that the user can’t see the word, but the search engine can see it. Of course, this is easily detected by search engines.

Later, someone changed the background from a single colour to an image file, and the content of the image was still white. Because the search engine can’t see what image or colour is in the image file, it adds difficulty to the detection. But if the editor looks at your web page, this technique is still easy to spot. It is currently unknown whether search engines have algorithms to detect such hidden text.

Hidden text also includes super-small numbers to the invisible text. Matt Cutts also mentioned before that colours that are close to the background may also be considered cheating.

With CSS, many web designers put the keywords they want to hide on the hidden layer, like the example above. Of course, the hidden layer in the CSS specification has a lot of its uses, such as drop-down menus. These applications are not considered to be cheating. But there are also some unscrupulous so-called search engine optimization experts who use CSS technology to hide text and links.

Although it has not been confirmed that search engines can crawl CSS files and determine whether they are malicious hidden words, but since search engines, especially Google’s ranking algorithm, are quite complex systems, I feel that there is no reason to believe that they cannot identify most of them using CSS. Hidden text cheats.
