SEO/SEM Lesson 1: Baidu spot price ranking analysis

Due to work needs, I have been studying SEO and SEM recently. I found several interesting questions from the bidding rankings of several key software development keywords.
.

Key words: Java,. net, PHP, embedded, testing

Symptom 1: Among the bidding rankings of these keywords, the Java bidding price is 7.99, the. NET bidding price is 0.99, and Java
Followed by embedded, testing, and PHP. The keyword bidding for Java is eight times that of. net, because most of the bidding price
Training Institutions, which means that Java training is eight times more popular than. net.

Symptom 2: Among the bidding rankings of these keywords, Java,. net, and the top three in the test are almost all taken by qingniao and Dani.
PHP and embedded are different training institutions, indicating that Java,. net, and testing have gradually entered the oligarchy age.
PHP and embedded are still in full competition, and there are still great opportunities.

Symptom 3: The joining force is very powerful. Seven of the top 10 training institutions in the Java bidding rankings are qingniao's branches.
The cainiao who do not know what Java is, will only know how to learn Java or even how to learn it.

Symptom 4: Baidu encyclopedia is the focus of technology promotion. Search for technical terms, such as Java, in addition to paid Promotion Network, basically
Baidu encyclopedia ranks first, and the websites that have joined Baidu encyclopedia for extended reading rank first.

Symptom 5: Although Baidu Knows it very well, it is in the public field. However, in the professional field, both the quantity and quality
It is a professional community like csdn, but it has already posed a threat to csdn. For example, some simple questions:

"Learning Java" is basically at the front of Baidu's knowledge and even Baidu's space, but the content quality is obviously inferior to that of professional communities.

Seo is still being studied. I will continue to share my latest experiences ..
