There are many factors to consider when optimizing search engines. The following elements are usually considered by all search engines and are very important:
1) webpage title
The title is always the most important. The performance, frequency, and position of keywords here will affect the ranking in the search results.
2) visible content on the webpage
The reason why a webpage exists is because of the visible content. When a user accesses this page, the most valuable part of this page is to see it. Generally, the content of this part should be neither too small nor too long. It is better to enter 200 to 600 words. The keyword density is about 5%, so it should not be too high.
3) reverse link (quality and quantity)
The reverse link is the import link. Its quality and quantity represent the quality of this page. A good link from a high-quality website will affect the page ranking.
4) link text of the reverse link
This text will affect the ranking of webpages when using this keyword to search. It is better to use keywords or related keywords for link text.
5) domain name age
The age of a domain name is related to its credibility. This does not mean that the credibility of a newly registered domain name is wrong, but it takes time to establish its credibility, just as in the society in which people actually interact, credibility cannot be created in one day.
There are hundreds or more factors that affect the search engine ranking, and the weights of these factors are different. At the same time, the search engine will make frequent adjustments to adapt to the changes in the online world. When making website optimization, you must always pay attention to this change to make timely adjustments.
