What are the TDK of SEO and what are their uses?

Title The title of the website.

Description description

Key words key words

Used for crawling and displaying for search engine spiders.

For example, if you need to go to Baidu (search engine) to see some information about raising cats, your first step is to open a browser about how to raise cats in Baidu (then "how to raise cats" here is the key word in seo, and "k" in tdk). Then Baidu will present rows of content. For example, how to breed xxxx cats (this is the title in seo and the "T" in tdk) is followed by piles of descriptive content, such as xxx is the xxx website for raising cats (this is the keyword in seo and the "D" in tdk).

So as an seo, it is very important to set the tdk of the website. Whether the title and second speed of each page can accurately and clearly describe the function of your website, whether the keywords match the content of the website and whether they match the search habits of users. Some people set the tdk in a mess, either the user didn't find what he wanted, or no user found the word, resulting in no traffic on the website. The most basic thing to do seo is to do tdk well, then optimize your keywords, improve the ranking of keywords, and let users find your website.
