What are the reasons for website blocking?

Possible website blocking:

1. Website content problems. Websites that are generally easy to be blocked include: Beautiful pictures, movies and videos, music, political content, sex-related content, and full-site content collection.

Note: Do not use banned words on the website. You can find the banned word on the Internet. Solution: change the content.

2. Keyword superposition

The website title is very long. A large number of keywords (more than 10) are often accumulated in title tags, keyword tags, and description tags ). There is no reason to place many keywords on the webpage (usually the footer. This is a very common issue of website blocking.

Solution: study SEO carefully and delete all the overlapping keywords. In short, make the text conform to the logic and look natural.

3. Hide text

Hidden text indicates that many words or links containing keywords are stored on the webpage. The color of these texts or links is the same as that of the webpage background (generally White, the search engine can be considered as a keyword or link. Hidden text is often reported by competitors and then manually checked by search engines. Once discovered, severe punishments will be imposed.

Solution: remove the hidden text and contact the search engine. For Google, you can use the administrator's background to send a letter to Google. Baidu is only waiting for now.

4. Group sending and group creation problems

The reason is that the website suddenly adds a large number of external links at the same time, and the anchor text next to the anchor text is basically the same. In addition to the same criteria as group creation, group creation often has the same IP segments. If there are too many blog groups, they may be used as mass groups because they have similar features.

Solution: prevent exceptions. Once it is K, there is no way.

5. Put pornographic ads on the website

1. Search engine problems

At any time, the search engine, especially Baidu's index database, only has 60% million web pages. That is to say, a large number of webpages are not included, and its own capabilities are limited to include tens of billions of webpages in Chinese. Therefore, most websites have experience of being deleted or K.

Solution: prevent exceptions. In serious cases, there is no way to recover.

6. Link to the blocked website on the website

Especially on the homepage, if the link is blocked, it may be seriously affected. Therefore, when connecting to the link, check whether the website of the other party has more than 5 points.

Solution: remove

7. Multiple website domain names direct

At the same time, several domain names direct to the same website. Therefore, the primary domain name selected by the search engine may not be the primary domain name you want to determine.

Solution: The vast majority of links on the home page use the absolute address of the primary domain name you think.

For example, if you create a directory under the primary directory of the primary domain name, such as a blog system, this blog system requires an absolute address, and then observe whether it is properly indexed. This is because many cases are blocked.

8. Website details

Make sure that robots.txt is normal, the website does not contain viruses, the website does not jump out of the window, and the website structure is not very special (it does not look very normal)

9. The website has no substantive content

For example: navigation stations, links to farms, or only a few pages, but the content is links to other websites, private server sites often have this problem.

Solution: None

10. Domain name problems

By viewing the log, we found that Baidu spider was not there, or was rarely there.

Solution: change domain name

11. IP problems

By viewing other websites connected to IP addresses, they are not included. (Baidu, query method)

Solution: change the IP address, if you can change the domain name at the same time.

12. Time problems

If there are many hundred-degree spider in the log, and the return value of the HTTP status code is basically 200, you need to wait for several days.
