This article mainly introduces the example analysis of HTTPS, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

HTTPS advantage

HTTPS is based on tls and ssl encrypted http protocol, network transmission is encrypted, so its security is obvious, including anti-eavesdropping, tampering, hijacking.

The inclusion Mechanism of HTTPS

1. How does Spider discover HTTPS

1), according to whether the hyperlink in the web page is HTTPS, there will be some hyperlinks in the network. If it is HTTPS, it will be considered as a HTTPS site.

2) according to the submission method of the webmaster platform submission entry, such as active submission, if the HTTPS link is submitted in the document, it will be found in the form of HTTPS.

3), refer to the crawling relative path of the front chain, the first page is HTTPS, the path in the content of the site provides a relative path, you will think that this kind of link is HTTPS.

4), with reference to the historical situation of the link, the reason for using this method is mainly for error correction. If you extract HTTPS by error, you will encounter two situations, one is because the HTTPS is inaccessible, the crawl will fail, and the second, even if you can catch the success, it may not be what the webmaster wants, so there will be some error correction.

2. Crawling HTTPS links

Now there are two common ones, the first is pure HTTPS crawling, that is, it does not have a http version, and the second is to redirect to HTTPS through http. Both of these two kinds of fetching can perform normal crawling with the same effect as http fetching.

3. The presentation of HTTPS

For HTTPS data, there will be obvious hints on the presentation side.

The webmaster platform supports site-wide HTTPS configuration.

1. HTTPS configuration

Before there are some webmasters change HTTPS, will ask why some links to the site is in the form of http to grasp it? Why isn't the whole station crawled in the form of HTTPS? Because the previous mechanism is url-level, HTTPS grabs one after another, and the whole site needs to be completely replaced. Now when you visit the webmaster platform, you can find that the left toolbar has more HTTPS authentication function, and the webmaster platform already supports HTTPS. After clicking this function, there will be a prompt to guide us how to do it. We need to be reminded that we need to support HTTPS all over the site before clicking. There will be some side effects on the site if it is not supported.

2. HTTPS verification

When the webmaster is configured on the platform, there will be HTTPS verification to confirm whether the webmaster is mismatched, and will check whether the https link is crawable. In addition, the certificate of HTTPS will be verified from these three angles, including its validity, expiration, and whether it is consistent with its own domain name.

3. HTTPS takes effect

After the verification is passed, the effective method will be carried out from these three angles.

1) grab the whole station in the way of HTTPS, which will make a certain switch in the grab.

2), the display style of the whole site will also be directly switched to HTTPS. The advantage of using this feature is that it will be much faster than before, and will skip the included web pages and go directly to HTTPS.

Frequently asked questions:

1. Will webmaster upgrade HTTPS affect crawler crawling? No, I won't. Crawlers can catch legitimate links to https.

2. Will the webmaster upgrade HTTPS affect the index volume? No, the construction of the database has been upgraded accordingly, and there will be no delay in the construction of HTTPS.

3. Will webmaster upgrade HTTPS affect ranking click traffic? No, the HTTPS transformation does not involve domain name switching, or the transformation of the old domain name to the new domain name style, etc. This is not involved, and the switch can be completely lossless.

4. Will the HTTPS upgraded by webmaster affect mobile adaptation? That's not going to happen.

5. Will the webmaster upgrade HTTPS affect the webmaster platform tools? No, webmaster platform link submission and other tools already support HTTPS.

Site recommendations:

1. It is recommended that webmasters jump from http to HTTPS. It is not recommended that there is only HTTPS, but there is no jump relationship from http to HTTPS. Users may encounter problems if only HTTPS is used.

2. It is not recommended that the two versions of HTTPS and http coexist. There are three problems in this situation, the first is that the maintenance cost is relatively high and two versions need to be maintained, and the second is unable to achieve absolute security, and there is a risk of insecurity in http access. Third, there is the possibility of inconsistency. With the long-term development, the two versions may become more and more inconsistent, which will affect the user experience. We suggest that the webmaster can make a certain jump preset to HTTPS after doing HTTPS.

3. It is not recommended for HTTPS to go back to HTTP. For example, if the webmaster returns to http and the user clicks on the link that has been shown to HTTPS online, it is not recommended that the user will show the style of dead chain when clicking in the browser. Be sure to consider this before doing this. If you really want to make a fallback, please submit the HTTPS check on the webmaster platform, and it is recommended that the site submit the fallback at least 24 hours in advance, so as to ensure that the webmaster's click will not appear in the form of dead chain, which is very important.

4. Do not provide hyperlinks on the Internet before the construction of the HTTPS page is completed. You have encountered several case before, but the HTTPS itself is not finished, and both versions exist, but the http is accessible to users, or the HTTPS page is a temporary fake page, so the site may be displayed in the form of HTTPS, which will cause user experience problems.
