So the ultimate goal of learning Seo is to forget Seo.

 

How to Master Seo
After learning about what Seo is, it may stimulate your interest in Seo. You will ask what to learn about Seo? In fact, Seo is not as powerful as you think. Simply put, you need to adjust the webpage to have a good "communication" with the search engine, so that the search engine can properly know Your webpage. If no search engine can find your website, let alone rankings. Because each search engine needs to find your website in a certain way, you need to follow certain rules on your webpage, otherwise, it would be like the old saying in China, "no chance to meet or not meet each other". The search engine's Guide to website administrators is a good guide to website construction.
Of course, this is not enough. You must master the following knowledge points:

1. Learn how search engines crawl webpages and how to index webpages
You need to know the basic working principles of some search engines, the differences between different search engines, and how the search robot (SE robot or web crawler) works, how does a search engine sort search results.

2. meta tag Optimization
It mainly includes the subject, description, and key words ). There are also some other hidden texts such as author, category, and language.

3. How to select keywords and place them on the webpage
Keywords are used for search. Keyword analysis and selection are one of the most important tasks of SEO. First, determine the main keywords for the website (generally in five upper and lower cases), and then optimize these keywords, including the keyword density (density), relevance (relavancy), and prominency) and so on.

4. Understand major search engines
Although there are many search engines, there are only a few that determine the website traffic. For example, Google, Inktomi, and Altavista are mainly used in English; Baidu and Sohu are used in Chinese. Different search engines have different page crawling, indexing, and sorting rules. We also need to understand the relationship between various search portals and search engines. For example, Yahoo and AOL Web Search use Google's search technology, while MSN uses Looksmart and Open Directory technologies.

5. Main internet Directories
Yahoo itself is not a search engine, but a large website Directory, and Open Directory is not. The main difference between Yahoo and search engine is that the website content is collected differently. Directories are manually edited and mainly include the website homepage. The search engine automatically collects directories and captures a large number of content pages in addition to the homepage.

6. Click-based search engines
Search engines also need to survive. As Internet businesses become more and more mature, paid search engines are becoming increasingly popular. The most typical examples are Overture and Baidu, and of course Google's advertising project Google Adwords. More and more people are positioning commercial websites by clicking ads on the search engine. There is also a lot of knowledge about optimization and ranking. You have to learn to get the most clicks with the least advertising investment.

7. Search Engine Login
After the website is complete, do not lie there waiting for the guests to fall from the sky. The easiest way for others to find you is to submit the website to the search engine. If you are a commercial website, the main search engines and directories will require you to pay for indexing (for example, Yahoo costs $299), but the good news is (at least until now) google, the largest search engine, is still free of charge and dominates more than 60% of the search market.

8. Link Popularity)
Web content is linked to each other in the form of Hyper Text, as is the case between websites. In addition to search engines, people also surf through links between different websites every day "). The more links from other websites to your website, the more traffic you will get. More importantly, the more external links your website have, the more important the search engine considers it to be, thus giving you a higher ranking.

9. Reasonable Use of tags
Search engines prefer H1. The h1 tag is a key learning point of seo.
According to w3cschool.com resolution, the h1 tag-h6 tag can define the title. The h1 label defines the largest title. The h6 label defines the smallest title.
With the rational use of the h tag, you can select an appropriate tag level to build the structure of the document.
From the seo perspective, after SEO optimization, the code of the webpage is indispensable for the H1 tag, because the value of its use is no less than the title. That is to say, the search engine gives a higher weight to the text marked with h1 than other words (the title is the highest, followed by h1 ).
The Title tag plays an important role in the website. The rational structure of the Title Tag not only highlights the subject of the webpage, but also helps improve the search engine ranking of the website, the following seo engineers analyze how to use the Title tag properly:
1. The Title tags of each page cannot be the same. the labels of the home page and the column page, list page, and content page cannot be the same. Set the appropriate Title tag Based on the content provided on the webpage.
2. The Title tag settings should be related to the content. You can set the Title, keyword, and overview.
III. The Title tag should be original and modified as much as possible. The content produced by the Title tag should not be used out of the box. Appropriate modifications should be made and some original factors should be added to help improve the indexing of Web search engines.
4. Do not set too many Title tags. Try to set them to less than 25 characters. The more concise the better. Just give an overview of the webpage subject content.
5. Set the keyword density in the Title tag to a maximum of three. Avoid accumulating and repeating keywords. The keyword density is too high, which may lead to search engine dislike. As a result, the search engine determines that the keyword is cheating, and the website will be downgraded.
