Summary: The fundamental purpose of search engine optimization is to improve the ranking of a website in search engines. That is, all the elements in your website are designed to achieve higher search engine rankings. These elements include: entry and exit pages, web page titles, page content, pictures, website structure, etc. In addition to the above elements, there are also keywords, links, HTML and meta tags. After all these elements on the web page have been optimized for search engines, the web page may still not be ranked high in search engines. Factors such as advertising and update frequency will also affect SEO results.
1. Understand support: classification and principles of search engines
Currently, commonly used search engines can be divided into three types according to their scope of use: mainstream search engines, secondary search engines, and dedicated search engines.
Generally, the search engines we can think of are mainstream search engines. They index most or even all websites on the Internet. Like Google, Yahoo! and MSN are all mainstream search engines.
The content of secondary search engines is not essentially different from that of mainstream search engines, except that its audience is smaller. It will not bring a lot of traffic and is only suitable for searches in certain specific fields. For example, Lycos, LookSmart, Miva, Ask.com and Espotting are common secondary search engines.
Dedicated search engines or topic-based search engines are highly targeted. The scope of its focus is very small, usually focusing on a certain topic, such as literature, health, catering and other topics. Common dedicated search engines include Yahoo! Travel, CitySearch, and MusicSearch.
In short, the web page sorting rules of various search engines are different. But their preferences for website structure are basically the same.
2. Website page factors: The ranking of a website in search engines depends on whether each element in the web page meets the search engine standards. There are some criteria that every search engine will focus on, including the website's text (keywords), tags (including HTML tags and meta tags), website links, and the website's popularity.
Text: It is the most important element of the website. Especially the keywords in the page text, including the location, frequency, accuracy, relevance, etc. of the keywords.
Tags: Meta tags and HTML tags are very important in SEO. In technical terms, meta tags are actually HTML tags that appear in specific locations. The two most important meta tags are keyword tags and description tags. HTML tags mainly include title (alt) tag, top-level title (i.e. H1) tag and anchor tag.
Link: refers to a real and effective link. Dead links can lower your website’s search engine rankings;
Popularity: Nowadays, search engines are becoming more and more user-friendly. Many search engines will use the number of times users click on a website in the search results as one of the ranking criteria. The more times it is clicked by users in the search results, the higher the ranking of the website will be.
Other factors: bold fonts, reasonable use of keywords in appropriate themes and content, concise and efficient standard div+css and try not to use JS calls.
3. External factors: mainly host server and domain name selection
4. Website page optimization: This requires a deep understanding of the various elements that search engines focus on and the impact of various elements on rankings, and at the same time, adding all these elements to the website as much as possible. Including the entry and exit pages of the website, the use of eye-catching titles, high-quality content, the use of images to improve website rankings, and the optimization of URLs and directories.
5. Programming languages and SEO: There are more or less differences between different programming languages and require different SEO strategies. I will talk so much today, and the detailed analysis has not been covered yet. We will discuss it together next time.
