How to prevent websites from being recognized as SPAM by search engines

(1) number of links for domain names and IP addresses

This method is generally used to query whether a website provides a dedicated link service page. If the number of exported links on this page is too large, the search engine may determine that the website is SPAM. Of course, navigation websites are not listed here. For example, the search engine has its own different algorithms and coping methods for websites such as hao123, 265, and DMOZ.

Solution: do not provide export links on a penalized website, or create too many external links on a page.

(2) keyword density determination

In fact, the accumulation of this keyword is easily identified by search engines as SPAM. For example, Jiang Pingzhong recently conducted an experiment and added a lot of weight loss keywords to a "weight loss Blog, for example, in the title, description, keywords, and other places, add "weight loss recipes, misunderstandings, weight loss rankings, diet pills, exercise weight loss, abdominal weight loss, slimming, fast weight loss, lazy weight loss, commonly used "Weight Loss" and other series of keywords, therefore, the search engine can easily identify it as SPAM, so the homepage will not be included, but will not be included in the internal pages. Generally, it is best to control the density of a keyword below 7%.

Solution: it is best to set the keyword of the page to 3%-7%.

(3) page similarity analysis

When many pages under the same domain name are similar or identical, the search engine determines that the website belongs to SPAM. Of course, some webmasters have no intention of sending several identical articles, and once again today. So, the webmaster may have to pay attention to this. When selecting a program, it is best to select the CMS or blog system that will prompt the repeated titles. For example, Dedecms will prompt when the title of the published content is repeated. The php Tutorial wind will also prompt when the same content is submitted several times during the publishing.

Solution: each page on the website must have unique content. Do not access a page from multiple addresses.

(4) content that netizens dislike or boast about

The correlation between keywords can be obtained from training SPAM samples and non-SPAM samples. Generally, "free" or "ringtone download" on the page cannot be regarded as SPAM. However, if "free" and "ringtone download" appear at the same time, it may be considered as SPAM. For example, Li Weihui's "SEO engineer" is registered with the China E-Commerce Association. Therefore, the SEO engineer certification is not officially launched by the search engine. The search engine is very likely to dislike its SEO certification series training, so it may also be recognized as SPAM. In addition, some well-known station group software and well-known collectors are also under pressure by the search engine, because this is exactly what the search engine prohibits, such as: Grand passenger station group and mad person collector.

Solution: avoid keywords such as "free lottery", "free prize winning activity", "SEO certification", and "free phone ringtones.

(5) create a SPAM blacklist

If a server IP address or cheating domain name is repeatedly recorded by the search engine, the search engine directly adds it to the blacklist or to the database for review and observation. Therefore, if a link is used for friendship, it will be jointly and severally liable for this type of punishment. For example, Jiang Pingzhong's grand client webmaster station had a link with the official website of the mad guy collector. Later, it was found that the station was K, causing the grand client webmaster station to be downgraded.

Solution: before registering a domain name, check whether the domain name has been registered or punished. When you select a server, check whether any domain name under the IP address has been punished by the search engine. Do not link websites that have been connected to SPAM During Friend links.

(6) leave a comment

Previously, I created some blogs, and later opened the comments and comments function. In this way, when some automatic messaging programs or spam links are recorded as messages, it becomes a "trap" and its Blog may be downgraded. For example, Lu Songsong's blog was originally PR5, and later opened the blog post message function, resulting in a comments of around-every day, followed by all the messages with links, which may leave some junk links, this causes the blog weight to decrease to pr3.
