What should we pay attention to in the construction and operation of scientific research websites?

　　 1. Common website

When exchanging websites, first check whether the website of the other party is normal and whether there is hang up or power down. If the other party's website is abnormal, it may cause our website to hang up or lower its power.

　　 2. Official website

When exchanging friend chains, we should pay attention to whether the exchange object of the website is a regular website. Exchange of friend chains with gray websites may cause our website to hang up and be blocked by k.

　　 3. Website content

Exchange friendship links, and try to choose websites related to and connected with this website. If the industry relevance between websites is not strong, the communication will have no effect.

　 4. The other party's friend chain

When adding a friend chain, first view the friend chain on other websites. If the number of friend chains is too large, the weight assigned to each link is very small, so this kind of friend chain addition has no effect.

　　 5. Keyword selection

When adding friendship links, try to use keywords with high website traffic and high ranking. Such keywords will drive website traffic and increase spider crawling.

　　 6. There is no follow in the website friend chain.

The nofollow code means "Do not follow the link on this page or this specific link". If you add it to such a website, the friendship link will not play its due role and will not have any added value.

　　 7. Exchange frequency of friendship chain

The communication of the friend chain on the website is a gradual process and a continuous work. After each snapshot update, 2-3 friend chains can be replaced. If you change too much in one day, it will attract the attention of search engines to judge the website cheating.

　 8. Regular inspection

Because of various reasons, the website friend chain will change from time to time, so it is necessary to check the website friend chain regularly to prevent single chain.
