Invisible texts, very common in Black Hat SEO!

[Ehsanuls55]

This involves placing a series of hidden keywords within the content of the website, so that they help the website rise in the search engine results lists. These hidden keywords are visible to search engines , such as Google, but not to users who visit the website.

The invisible text technique, in Black Hat SEO, consists of publishing texts and keywords on the web page that are seen by users who visit the website, but are visible to web search engines, with the aim of moving up positions in the results lists.

There are several ways to include invisible text: publishing white text on a white background, text behind images, text that is not visible because its size was set to 'zero', text with styles (CSS) that hide it, etc.

As with other practices, web search engines have long since developed mechanisms to detect this practice and severely penalize any website that opts for it.

Hidden redirects
Hidden redirects represent a Black Hat SEO technique that has been very useful in the past to achieve a better position for a website with little traffic from another website that is well positioned in search engines. This is known in SEO as “ transfer of authority ” or “transfer of position in the SERP”.

Although it is a very old SEO technique, it has been violating Google's regulations for some time now and is currently of little help in achieving the true authority and positioning you want for your website.

Hidden redirects are an SEO technique, which has been penalized for some time now, that seeks to transfer authority from a very well-positioned website to another website so that the latter improves its positioning in the search engine results lists.

Instead of using this penalized SEO technique, there are other methods, such as using 301 redirects or canonical URLs correctly. This way you guarantee the correct transfer of authority, for example when redesigning or migrating a website, or showing similar content between two sections, without cheating or trying to deceive Google, and ensuring that your website will not be vp design officers email list classified as a low-quality site or with duplicate content.

Low quality content ( Thin Content )
Low-quality content, or Thin Content in English, is a hidden card that many websites use to try to improve some positions in search results, but it leaves a bitter taste in the mouths of users and Panda , the algorithm that Google created to detect this type of practice and low-quality content.

Google launched the Panda algorithm to detect web pages with low-quality content and penalize them by lowering their position in the results lists or even eliminating them completely from its results.

Within this technique, we can mention repetitive and empty content that does not specify a topic or is not clear, content that appears (in the SERP) to talk about one topic, but talks about another, and content that, far from having been created to satisfy the user, is only full of keywords and links whose purpose is to gain traffic or sell a product.
