Analysis of the advantages and disadvantages of www. ****. com external link form in seo optimization

Recently, when I visited some news articles in a5, I found a phenomenon, that is, many articles have webmasters and friends who leave Web sites in various forms, the most common way to leave a link is www. word. com, many webmasters think that using this link can also leave a valid external link for the website. Is that true?

I think a complete form of external link should be http: // www. ***. com/, but currently we can see a lot of such link forms through the query, 1 is www. ***. com/, 2 is www. ***. com, 3 is ***. com/, 4 is www. ***. com, 5 is ***. com, these links can be found in Baidu search engine. Today we will mainly discuss the fourth form of external chain. Next we will go to the topic.

Advantages of www. ****. com external links

1. Use www. ***. com is a form of external chain that can avoid a lot of trouble. We all know that it is not easy to keep external links in the forum. Administrators are also eager to keep their eyes on gold every day, if you leave your website address directly in a forum, I think the consequence is that your ID is blocked, because many website administrators think that this behavior of purely leaving addresses splits the weight of the website and uses www. ***. this problem can be avoided by leaving external links in the form of com. Many administrators usually see this form of links with great compassion. I have compared these two methods before, it is found that the link survival rate with space addition is more than 80%, and the link survival rate without space addition is less than 30%.

2. Use www. ***. the construction of the external chain in the form of com can also help the construction of the external chain smoothly. I do not know that the webmaster did not find a problem during the construction of the external chain, if you are at www. without spaces, the external links you have made will not be displayed. Generally, there are three forks,

 

We can see that the webmaster wants to leave a link, but only three forks are left. Let's take a look.

 

The difference between the first and the second is that the first form of external link is the space method, which makes the external link visible, we can use this function on some large websites, which uses www. ***. A major advantage of the form of com external links.

Disadvantages of www. ***. com form external links

Www. ***. although com can help websites quickly build external links, it also has many drawbacks. I think the biggest drawback of using this form to build external links is that the effect is not good enough, the best form of external links is keyword hyperlinks, followed by plain text links, which I think are www. ***. com-form external links can only serve as 3 percent of the hyperlink, that is to say, building 33 such external links can withstand the previous hyperlink, many new webmasters do not know how to analyze the external links, I have wasted a lot of time every day to keep some of these external links under articles on Sina, Tencent, a5, chinaz, and other websites. I don't think this is necessary, if you really want to build external links to build some plain text external links, the effect is better than this. Let's think about it. What does a search engine spider use as a crawler when capturing it? What should I do? Therefore, it is recommended that you do not perform this external link mode when conditions are met, because it is a waste of time.
