1. Connection quantity principle
Determine the relevance of a webpage to the keyword based on the number of links that appear in the webpage from other webpages. For example, according to the keyword "apple", 3000 web pages are linked to webpage a on the Internet, and only 2000 web pages are linked to webpage B. In the search results, a ranks first, B ranks below.
2. link quality principles
When the number of links is the same, the higher the quality of the parent-linked webpage, the higher the ranking of its sublinked webpages. The concept of Web Page quality will be introduced in Section 2. 3. Generally, it can be understood as a well-known web page, and its quality is higher.
3. Principle of Location/frequency
Determine the relevance of a keyword in a webpage based on its location/frequency.
1) The title takes precedence over the webpage
The title of "Hangzhou Siyi ou search engine optimization service provider" is the top line. For example, when you search for the keyword "siyiou", webpage a displays "siyiou" in the title, while webpage B does not show "siyiou" in the title, and only "siyiou" appears in other parts of the webpage ", if other conditions are the same, a ranks first in the search results, and B ranks last in the search results.
2) priority before keyword location on the webpage
The higher the keyword appears on the webpage, the higher the ranking. For example, when you search for the keyword "Jeans", webpage a shows "Jeans" on the third line, and webpage B shows "Jeans" on the fifth line. If other conditions are the same, in the search results, a is ranked first, and B is ranked later.
3) Priority for high intermediate frequency of webpages
The more frequently keywords appear on the web page, the higher the ranking. For example, when you search for the keyword "stockings", the word "stockings" appears on webpage a eight times, and the word "stockings" appears on Webpage B only six times, if other conditions are the same, A is ranked first in the search results and B is ranked later.
When a keyword appears too many times on a webpage, it is considered cheating by the search engine and thus disqualified from ranking. Generally, the number of keywords should not exceed 8% of the total number of words on the web page.
4. Click measurement principles
It is generally considered that the quality of a page with a large number of clicks is high, and the ranking is also top. For example, in the past three months, the average number of clicks on a web page is 3000 IP addresses/day, and B web page is 2000 IP addresses/day. If other conditions are the same, in the search results, a is ranked first, and B is ranked later.
