What are the operational methods of black hat SEO

Now there will be some introductions on the Internet or in some other groups, but it is not recommended to use black hats to optimize**, because this is not a long-term solution, or a formal method to operate.

1. Keyword stuffing Keyword stuffing generally refers to the appearance of a large number of keywords that are not highly related to the content on a certain page, and these keywords are generally repeated many times. Generally, this practice is to increase the density of keywords, and it seems that very few people use it at present, because this is also the most disgusting thing for search engines.

2. Hidden text (hidden text) It is generally common to set some keywords to the same color as the background, so as to achieve the effect that the browsing user cannot see. There is also the font small, which is generally impossible to detect with our eyes. This practice can be seen by spiders in general, and the main method is to increase the density of keywords without affecting the user experience.

3. Cloaked page Some web pages use programs or scripts to detect whether they are visiting search engines or ordinary users. In the case of search engines, the page returns an optimized version of the page. If you visit an ordinary person, you return to a different version.

This is a form of fraud that is usually undetectable to users. Because once your browser goes to this web page, whether it's on the page or in the html source file, what you get is already a different version than what the search engine sees. The way to detect this is to take a snapshot of this web page.

4. Hidden tags Those hidden tags are also overused, such as comment tags, style tags, etc. Putting keywords in these tags is a common practice for SEO cheaters.

5. Doorway pages are usually used to automatically generate a large number of web pages containing keywords by software, and then automatically redirect from these web pages to the home page. The goal is to hope that these bridge pages targeting different keywords will rank well in search engines. When a user clicks on a search result, they are automatically taken to the home page.

Sometimes it's a bridge page that puts a link to the home page without automatically turning. Most of the time, these bridges are generated by software. As you can imagine, the generated text is disorganized and has no logic.

1. Content cheating.

The purpose of content fraud is to make the content of a web page uncommensurate with its search engine rankings by carefully altering or modifying the content of a web page. Search engine ranking algorithms generally include content similarity calculations and link importance calculations, and content fraud is to achieve the final high ranking by improving the score of content similarity calculations. The essence of this is to deliberately increase the frequency of the target word.

There are several common ways to cheat content:

2. Cheating on irrelevant query terms.

3. **Alt tag text cheating.

4. Cheating of web page titles.

As a summary information describing the content of a web page, the title of a web page is a very important heuristic factor for judging the topic of a web page, so search engines often increase the weight of the title words when calculating the similarity score. Cheaters take advantage of this by repeatedly placing target words that are not related to the topic of the web page in the title position to get a high ranking.

5. Cheating on important tags on the web page.

Unlike normal text formatting, web pages are tagged with html, and some tags represent important meanings, such as boldingMarkup, paragraphs.

6. Content agricultural poplar.

1. Use API and RSS to collect other people's blog content and place the content in your own ** or blog;

3. A large number of poor quality and repetitive information content generated by tools automatically in batches;

4. Simply copy other people's original content into your own ** or blog.
