Considerations for connecting websites

Provides a local http://tool.111cn.net for connecting to batch queries

1. Use rel = nofollow in links

When talking about cheating on friendship links at the webmaster's party, the webmaster of the universal navigation network said this situation, saying it was a communication with a website, at that time, I saw the peer's PR value = 5, and the website was well indexed. After doing so, I thought it was a big bargain. One day, if you want to learn from a feature on the website of the other party, you can view the source code of the website of the other party and find that your link is "universal navigation network ", there is a rel = "nofollow" code in it, and it is strange to check it on the internet. The query result is "in robots, If nofollow is set, the links will not be crawled by search engines. When you search for a website in the engine, the system first checks that the website root directory contains a plain text file called robots.txt. The Robots.txt file is used to limit the access scope of the search engine to its website, that is, to tell the search engine website which files allow it to be searched (downloaded. The link does not exist until now because rel = nofollow exists. I was very angry at the time, but I also reminded my webmaster that I must pay attention to this detail.

2. Hijack a prvalue website

In terms of habits, we are always willing to exchange connections with websites with high PR, and always think that links with websites with high PR values can increase the PR value of our websites. In fact, the reason why the PR of the other party is so high is discovered after a peak network friendship connection. Determine whether the other party is a hijacked PR, you need to carefully study the other party's website, to see how the website is indexed, how the reverse link, etc. to comprehensively determine whether the domain name is hijacked by the PR value, if yes, so do not do such a link.

3. Use iframe or JS call or flash or image

Baidu and other search engines do not recognize iframe, js, flash, and image applications, as clearly stated in the webmaster's book. This clearly tells us that if the other party uses "iframe or JS called or flash or image" when making a link, the link will be meaningless! Because flash and images are easy to determine, how can I determine iframe and js? You can only query in the source code.

4. Websites that are being punished by Baidu and Google

This problem seems simple and complex, because the above sentence contains two meanings, mainly including:

(1) Make sure to check whether the website of the other party is K. Baidu K website is not only all K, but may also be a homepage or a topic. For details, refer to the article Baidu K website has implemented a precise attack, the above explanation is very clear.

 

(2) reducing the weight of a website is a barometer of the punishment by Baidu and other search engines. How can we determine that the weight of a website is reduced? In my opinion, we can query the Baidu snapshot date, change the PR curve in the search engine, and speed of indexing. For details, refer to the article "top network teaches you how to determine the weight of a website.

 

 

5. Illegal websites or websites with viruses

Nowadays, search engines are very disgusted with websites with viruses, and K websites that do not comply with national policies and regulations are even more powerful. Therefore, if the traffic on other websites is too high, you are very happy to exchange connections when the PR value is high. At the beginning of the peak network, because it was just a rush to do the link, and finally got tired, it was not until today that it was gradually restored.
