I happened to be offline today, so I had some time to write this article. From the early SEO pioneer Wang Tong to the current large number of rising stars, SEO has a history of nearly ten years in China. Some SEO experiences have gradually become a rule under the guidance of predecessors. The law is the same, whether it is right or not. Many are not given proper instructions. Just like BD, it excludes SEO optimization, so it is impossible to give each SEOER an SEO industry standard. Because of the relationship between predecessors, it may have caused misunderstandings about SEO. I didn’t want to write the following content, but recently I still have some misunderstandings with many SEOERs who have worked for many years, so I decided to talk about some misunderstandings that are not easy to detect. I hope it will be useful to everyone.
1. BD’s reverse link query instructions
SEOER has long been familiar with the commands for checking several major search engines. For example, when checking link:www.xxxx.com, the link command is also recognized as the standard for this command. In many webmaster tools, link is also considered a recognized command query. But this method is not universal. In Yahoo, you need to add "http://" before the domain name. Not all results found by this command can be displayed in GG, but this can be found in GG's webmaster tools. The current saying of backlinks is that if there is a link on webpage A that points to webpage B, then the link on webpage A is a backlink to webpage B. We can take a look at the backlinks queried in GG and Yahoo. However, in BD, Link does not represent a command, it is just a keyword search containing "link:www.xxxx.com". Some people will say that Baidu’s command for checking backlinks is domain. We can try it, domain: www.365uh.com. However, the search results given by Baidu are all domain names that contain URLs, and some have no backlinks at all. Just like articles published on A5 with website domain names, if there are no links pointing to this domain name, these cannot be regarded as backlinks. Domain is just a general instruction. After investigation, it was found that BD did not provide a clear explanation of backlinks at all. Therefore, BD did not have a so-called backlink check instruction. This is also one of the misunderstandings of many SEOERs. I believe that at least 80% of SEOERs will misunderstand this, including me, who was also confused for a long time.
2. Understanding of PR
Let us first review the factors that affect the PR value: (1), the quantity and quality of external links to the website; (2), the number of pages crawled by Google on your website; (3), the website is ranked by the world's three most well-known websites Included in DMOZ, Yahoo and Looksmart
PR may talk more when making friendly links. Some SEOER always believe that linking a site with a high PR value to a site with a low PR value may reduce the site's PR value. The more exported links, the more detrimental it will be to the improvement of the site's PR value. We can take an example of this, the friendly link exchange platform. It exports enough links. I believe that the PR of the websites that go there is generally not very high. For such a large number of exported links, the PR value of the link is low. As for the friendly link exchange platform, according to what I just said, its PR improvement is very small. However, we will find that the PR value of many friendly link exchange platforms is very high.
On the other hand, does it mean that for a website, the more external links it has with higher website quality and higher PR score, the better? Wrong, because GG’s PR system does not only consider the external aspects of a website. The quality of links will also be taken into consideration as well as their quantity. For example, an external link site with a PR score of 6 can significantly increase your PR score. But if this external link site already has 100 other external links, then the PR score you can get is almost zero.
The above two points are some of my own opinions. Some experienced webmasters may scoff and just think that I am talking to myself. In fact, my idea is very simple. I just want to share my experience and communicate with everyone. It is better to have fun alone than to have fun with everyone, so why not do it. If I am wrong, I hope you can correct me, and I hope more and more sharers will join.
