What is the function of SEO and HTML semantics

This article introduces the knowledge of "what is the role of SEO and HTML semantics". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Basic concept

SEO: (Search Engine Optimization) means search engine optimization. Search engine optimization (SEO) is a way to improve the natural ranking of target websites by using the search rules of search engines. To put it bluntly, it is the self-promotion of the brand, so as to make a profit.

HTML semantics: according to the semantics of the structure of the content, choose the appropriate tag (code semantics) to facilitate developers to read and write more elegant code while conducive to SEO optimization.

The purpose of using SEO and semantics

A basic exposition has also been made before:

SEO is for the self-promotion of the brand, so as to make a profit.

The purpose of semantics:

Without css, the page can also present a good content structure and code structure.

Improve user experience: for example, title and alt are used to explain nouns and picture information

Conducive to SEO optimization: establish good communication with search engines, help crawlers grab more effective information, and crawlers rely on tags to determine the weight of context and keywords

Convenient for other devices to parse, such as screen readers, blind readers, mobile devices

Semantics is more readable and convenient for team development and maintenance.

Semantics and the importance of SEO

Google, Yahoo, Bing conventions to parse the tags listed in http://schema.org.

The reason is actually very simple, because schema tags are very important to search engines. At present, the development trend of search engine is omnipotence and simplification, so that users can get the desired information in the shortest time and get enough information to judge before clicking on the search results.

For example, Google general search,Google will recommend web pages, news, pictures, videos, music, products, maps, local results, real-time results, etc., based on the keywords you search for.

For example, Google onebox,Google will directly give targeted results according to some specific instructions, and now the search engine can directly check the weather and flights.

There are also screenshots and previews of the website launched by Google some time ago, snippets lists and so on.

The goal of Google is to integrate all resources so that users can easily access them. There are many kinds of resources, text can be fully identified by search engines at present, but pictures, flash, music, video search engines can not or can only identify a small part, so with the current technology, it is not possible to integrate all the resources presented on the site, so users need to cooperate.

I think this is the meaning of semantic tags.

Search engines hope that each website will mark out different resources and label them as easily identified by search engines, so that they can judge and classify them and better present them in the search results.

From the SEO point of view, what is important for search engines is important to SEO.

If the website rewrites the code according to the rules on schema, it is convenient for the search engine to grab the information, it will be very helpful to the presentation of the site content in the search results, and can adapt to the development trend of the search engine. It may not have an obvious effect on some keyword rankings, but in the long run, it should be of great help to get traffic from search engines.
