Hunchun SEO training: some basic knowledge of search engine optimization

There is a lot of common knowledge about SEO optimization on the Internet, and many novices don’t know how to choose. Below, Dongguan SEO Feng Chao shares some SEO optimization related knowledge, hoping to help SEO novices learn more about the basic knowledge of search engine optimization.

1. Choose a good primary domain name and standardize the URL. Usually we will resolve the domain name into two, one with www and one without www. For search engines, these are two pages, so we have to recognize the main domain name and do a good job of 301 redirection. If 301 redirection is not possible, just parse one domain name with www. (Click to see how to complete 301 redirect) URL standardization means that the links within the site are pseudo-static.

2. Breadcrumb navigation Breadcrumb navigation (or breadcrumb trail) is a kind of navigation that shows the user's location on a website or web application. The breadcrumb navigation is your location: For example, the breadcrumb navigation in this article: Your current location: SEO Blog > Search Engine Optimization Basics > SEO Optimization Basic Knowledge Encyclopedia Essential Knowledge for SEO Beginners Good breadcrumb navigation can help visitors understand the website content more clearly and facilitate the user experience.

3. Weight tags For SEO, the most important tags of a website are the title tag and the description tag. Keywords must be added to these two tags. There is also the H1 tag, which also contains keywords. There are also various labels that make the font bold, italic, and change the color. The main purpose is to emphasize the role of some content, and it is recommended to use them appropriately on policy keywords.

4. Site map Through the site map, the spider can quickly understand how many web pages your website has and crawl them quickly, and it will present the situation where the spider cannot crawl because the directory structure is too complicated. The main purpose of the site map is to increase the amount of inclusion. Friends who don’t know how to make a website map can refer to the article “How to make a website map”.

For example, if you use ADSL, you may be assigned a different IP after disconnecting and reconnecting.

UV: refers to unique visitor, that is, a computer client that visits your website is a visitor; the website can be visited independently every day, and there can be multiple computers under one IP, so the independent visits of these multiple computers are counted as multiple UVs. (In fact, a computer does not necessarily have one UV, it may be multiple. Because a computer may be used by multiple people, the search engine will identify it based on different information.) PV: refers to the page reading volume, the total number of times all pages are read. When a page is refreshed, the PV will increase by 1.

For example: a company has 200 people and 200 computers, and these 200 people share one IP, then one person in this company uses his computer to visit your website and reads 3 pages, this is 1 IP, 1 UV, and 3 PV. After a while, 3 other people in this company use their computers to visit your website and read a total of 6 pages, this is 1 IP, 3 UV, and 6 PV. So don't be surprised if you often see the number of IPs and UVs different in accounting tools. 6. nofollow tag The nofollow tag is commonly used as an HTML tag added to a hyperlink. It tells the search engine not to follow the link of this website. You can add this code when you need to add a link to a page but don't want the search engine to crawl along the URL. Then the search engine sees this tag and may reduce or completely cancel the voting weight of the hyperlink. The nofollow tag was originally created by Google to minimize the impact of spam links on search engines.

7. It is difficult for every website to have a good ranking at the beginning of its launch. This is the so-called sandbox effect during the new site query period. Therefore, before preparing to build a website, it is necessary to confirm the layout and keyword selection of the website, and avoid frequent changes to the website during the query period. For example: modify the title, description, layout. The inclusion will be slow during the query period. New webmasters should be patient, take a long-term view, and insist on daily content updates.

8. Friendly Links Most websites have a friendly links column at the bottom or right side of their homepage. Friendly links are a type of cross-links, which means you link me and I link you. It is best to have friendly links only on the homepage (here refers to small websites, such as medical websites or other large websites). Suppose you have added friendly links throughout your entire site, and others have only added a friendly link module on their homepage, when you exchange with them, the weight of your website will be transferred to them, which is not worth the loss.

9. Cross-linking Cross-linking still needs to be achieved through communication links. Generally, friendly links are only link exchanges between two sites, while cross-linking is link exchanges between three or more sites. For example: I have two sites, one is A network and the other is B network, and the person who communicates with me has a C network, so I want to cross-link with you to focus on increasing the weight of A network. Then the cross-link is that "B network" links to you "C network", and "C network" does not need to link to "B network", but directly links to "A network". Cross-linking is generally not easy to check, so it is more suitable to do it among friends!
