Common Google ranking optimization SPAM technology

The optimization methods are diverse. Generally, the website structure, Page factors, and external links are optimized based on certain keywords to obtain the best search engine ranking for the website. But in fact, we found that some websites not only fail to effectively improve the ranking of websites due to incorrect optimization strategies, but also make the rankings fall sharply or even be deleted by search engines. Here we will list SPAM-specific optimization technologies that are banned by Google for your reference.
1. Hide text/hidden links
Generally, a webpage is a text content or link that is designed for search engines but cannot be seen by ordinary visitors. Among the various hiding technologies, the most common is to set the font color of text or link text to the same or very close to the background color.
Hide text content (Invisable/hidden text)
It is intended to improve the keyword relevance score through a webpage containing a large number of keywords without affecting the website's appearance, so as to improve the search engine ranking.
Hide link (Invisable/hidden links)
It is intended to add invisible links to the target optimization page on other pages without affecting the website's appearance, and improve the search engine ranking by improving the link score.

Currently, most search engines detect hidden technologies and are considered cheating. Therefore, webpages that contain hidden text are punished by search engines for reducing rankings or even deleting lists. Although Google does not have many websites that are lucky enough to escape using stealth technology, most people still think it is not worth the risk. In fact, by adding visual text content and ensuring a certain keyword density, the same optimization effect can be achieved.
2. The webpage does not match Google's description
Generally, a website is submitted to the search engine first, and then replaced with another page after the website is indexed. "Bait-&-Switch" is like this: Create an optimization page and a normal page, and then submit the optimization page to the search engine, after the optimization page is indexed by the search engine, it is replaced by a normal page.
3. Misleading or repetitive keywords
Misleading Words)
Use misleading keywords irrelevant to the webpage in the webpage to attract visitors who query the subject to visit the website. This method seriously affects the relevance and objectivity of the results provided by the search engine, which is a deep headache for the search engine.
Repeated Words)
This kind of cheating technique is also called "Keyword Stuffing )", it uses the search engine to pay close attention to the keywords in the webpage body and title to repeat the keywords unreasonably. Other similar practices include creating a large number of keywords in HTML meta-tags or using multiple keywords meta-tags to improve the relevance of keywords. This technology is easily noticed and punished by search engines.
4. Cloaked Page)
Hiding real website content from any visitor or search engine to provide non-real search engine-friendly content to improve rankings.
