CMS stands for Content Management System which is a website's content management system, which controls all activities about the content and information of the website. This includes news, photos, videos, categories, contact information, etc. on the website. In particular, with advanced CMS, users can also edit, categorize categories, even change the interface display and many other complex operations on the website.

Programmers write the functionality of the website, but it is the content that makes the website shine.

Programmers are responsible for giving birth, but marketing and content are education and upbringing.

What is SEO?

SEO is an acronym for Search Engine Optimization (search engine optimization), is a process of improving the ranking of a website on search engines so that users can find a website more easily on the search results table.

What HTML tags are important for SEO?


  1. Title tag in header
  2. Meta tag in header
  3. Heading tags (H1 > H6)
  4. Image alt text
  5. Schema markup

  6. HTML5 semantics tag

  8. Canonical tags (more details)

Google is their database search service. To build this database, they will have to build a lot of robots crawling data. So fast servers, clear structure will help them save a lot of costs.

In addition, for users, everyone prefers a fast website over a slow one

POST or PAGE or custom content all come from the same database table of wordpress. Where POST ID is the primary key to bind other strings. Let's see a wordpress REST API example related to post 


Thus, all WordPress data is saved in the form of POST template. Then defined into different formats such as ROOM, SERVICES, PAGE, TAG, CATEGORY ...

And other extra features such as: save languages, save revisions, save drafts, save media...

Therefore, in the programmer's experience, in addition to looking at the URL, you also have to know how to see the post's ID. For example, when editing, notice the text postID = ###

Default to access a page without remembering the link by www.website.com/?p=123 (123 is the post ID)

In addition, to add a custom field, you can use the default custom field of wordpress (not user-friendly). Or use the PODS plugin. See instructions here

File wp-config.php – This is the connection file between the MySQL database and the PHP code. In this file will contain username / password and database connection information. This is the first setting to do when making a wordpress website

WordPress Settings

  • General: this is the second most important settings item in wordpress, it should be done right from the login step to the site. In it, do not leave any boxes blank
  • Permalinks: the third importance because it will help the website to be clear and easy to read. As well as good for SEO and caching (default does not cache when the URL has parameters)
  • Reading: starting to set up the web, this part can be done later, not too important
