The website status code is an important observation indicator to help us grasp whether the website is operating normally . In addition to the 404, the website status code actually has two very common website status codes: 301 & 302 redirects (commonly known as redirects). Address), which are also the site conditions that we will pay special attention to when operating the website SEO optimization.
It is precisely because it is very important that I will introduce to you how the 301 and 302 redirects actually work today. What impact will it have on website SEO optimization? And how can we cooperate with optimization engineers to reduce the impact of redirection (relocation) on optimization results?
First of all, we must first understand, what exactly are 301 and 302 redirects?
301 Redirect (Moved Permanently) ─The webpage has been permanently migrated, that is, it is permanently redirected to other webpages.
The page you requested has been permanently moved to a new page. For example, if you originally wanted to enter the page of http://www.xxx.com.tw (the page using the Http protocol), you will automatically be directed to the page of https://www.xxx.com.tw ( Use Https security agreement page). For search engine optimization, using this website code can notify search engine spiders that a webpage or website has been permanently moved to a new webpage.
302 Redirect (temporary move) -the webpage is temporarily moved to another webpage
302 forwarding is actually similar to 301. Actual observation will also reveal that the website will automatically go to another URL. However, for search engines, because search engine spiders will continue to crawl the original URL location and index it, a certain When a page or website has been moved, do not use this code to notify search engine spiders, unless there is a temporary change, otherwise it is better to use a 301 redirect for permanent and long-term changes.
Taking a closer look, how to understand the 301 and 302 redirect (jump) situation?
Jump usage:
If the address of the original page was http://www.xxx.com.tw/A.html (hereinafter referred to as page A), now it is set to http://www.xxx.com.tw/B due to business needs. HTML (hereinafter referred to as page B), although there is no difference for visitors, but for search engines, because page A and page B are different pages, we need to tell search engines that page B is the original page A At this time, you need to use the jump method to process. You can choose 301 or 302. The difference between them is:
Use 301: 301 represents a permanent jump. If page A has been indexed by a search engine, set 301 on this page, and the search engine will know that you have changed the URL to page B. Next time the search spider visits the site again, it will index the website from page B, and the database will include A The page is deleted and replaced with page B. When you have set 301, the weight ranking of the original A page can be transferred to the B page more completely.
Use 302: 302 represents a temporary jump. The difference between 302 and 301 is that the search engine database will not delete page A, but will still increase page B, but the weight ranking of the original page A will not be transferred to page B.
Consequences of not using 301 and 302 redirects
If the website administrator modifies the page link and changes page A to page B, but does not set the redirect attribute on the server (IIS, Apache, Websphere, etc.), then although there is no impact on user access, the search engine does not know it. Will lead to two bad results:
Generate 404 status
The search spider will still try to visit the original A page (there are two possibilities: 1. The search engine database has not been updated, and the A page is still reserved, so it will visit. 2. The external links of some outside websites are still A pages, After the search engine crawled, they still visited page A), and found that it was a 404 status. Because 404 means that the website is wrong, the search engine thinks that the website is not done well, so it will penalize the website, and the ranking of the website will drop because of the display error The website of is a very bad experience for users.
2. New page optimization is slow
After a while, the search engine found that there was an extra page B on the website and included it, but because there was no redirect, it thought it was a brand new page, which had nothing to do with the original page A. The weight and ranking of the original page A were just If it will not be transmitted to page B, page B will start the ranking calculation again . Generally speaking, it will take 2-3 months. If the original ranking of page A is good, then page B will be very disadvantaged if it restarts the calculation.
301, 302 redirection, where applicable
When we operate a client’s website, we often need to use redirection (forwarding), mainly as follows:
Change of communication protocol: http to https
Change the official website, website revision (the website has big changes)
For pages with duplicate content but different URLs, the weight is concentrated. At the same time, avoid Google's penalty for duplicate content.
Standardized URL: Import the URL weights of www and http into the same page.
When a customer has a website change similar to the one mentioned above, we welcome you to take the initiative to contact us to facilitate the maintenance and operation of the website SEO optimization effect. The benefits of doing so for you will be further explained later.
301, 302 Consequences of improper use
Because 302 is the meaning of a temporary jump, if it is used for long-term jumps, search engines will think that this is the weight of the website using the 302 jump to transfer the A page, cheating on the B page, and the website will be punished . Since search engines are uncertain about the judging rules of jump time, it is not recommended to use 302 jump if it is not necessary. (Google has always emphasized the use of 301 instead of 302)
