7. Understand “spiders” and improve website inclusion
The spider is an automatic program of the search engine. Its function is to access HTML web pages on the Internet and build an index database so that users can search the web pages of the website in the Baidu search engine. Simply put, it is a tool for websites to communicate with search engines. It is with spiders that search engines can know your site, and then it can include and rank it. Because the spider is an automatic program that relies on various set rules to act, so by tracking the spider's movements and the search engine's response, the website can be optimized in a targeted manner.
1. New website goes online to attract spiders
After the website is online, the page is first submitted to the search engine. The search engine will analyze the links contained in it and then crawl it. Since it is a new site, the spider will not respond very quickly after submission. It may only crawl one or two pages at a time and leave, waiting until next time to continue. Fetch the page.

There is a special issue that needs attention in the early stage of the website, that is, the website must not have dead links and bad links, and the stability of the website server must be ensured. In other words, a good crawling environment must be created for spiders, because once the spider encounters a dead link It will just "walk away". If the website server is unstable, the spider may circle around and leave without even crawling a page. We also need to ensure that the internal links of the new site are hierarchical to ensure that spiders can better crawl the content and make browsing more convenient for users.
In the early stages of establishing a new site, friendly links play a very important role. They can greatly increase the number of times spiders crawl the new site and shorten the site's inclusion time to a certain extent. When a new website is launched, the data should not be too little, but should have enough data, and the internal links should be reasonable. Only in this way can it be a well-formed site, and the impression score of this site will be very high when spiders crawl it.
Generally, it takes about half a month for a new website to be included in Baidu, but Google spiders crawl the web more frequently than Baidu spiders, and new articles may only be included in 2 days.
2. Check spider tracks
When the search engine's inclusion of the website enters a stable stage, there is a little trick that can increase the number of crawls by Baidu spiders. Don’t update the daily update content all at once. You can update part of it every 2 hours or update it in batches.
Because at this stage, some Baidu spiders enter through the homepage and leave once they find that the homepage has not changed. In this way, the benefits of regular and quantitative updates are revealed. Once a spider enters the homepage and finds that the homepage has changed, of course it will crawl more frequently. At the same time, pay more attention to the time period when spiders crawl. Update during this time period, and the speed of inclusion will be the fastest.
This requires a tool that can check spider movements at any time. Many CMS have such a function, which can clearly record the robot traces of various large search engines, including dwell time, crawled pages, etc. There are detailed data, you can Analyze daily crawls, or compare which columns have the most crawls.

Familiarity with the time patterns of spiders crawling websites and the columns spiders prefer to crawl can help webmasters increase the number and speed of inclusions. At the same time, it can also be compared from the side to find out which channel has a higher weight.
8. Cleverly speed up web page display speed
The display speed of the website is not only related to the server of the website, but also the page settings and code references of the web page will also have a great impact on the loading speed of the web page. How to speed up the display speed of the web page and enhance the user's browsing experience, let's start with detecting the page loading time. , and then introduce ways to speed up web page display.
1. Cleverly use plug-ins to detect page loading time
You can intuitively see the loading speed of the website by accessing it directly through the browser, but the network environment for browsing the website is different. If the website loads a lot of special effects, it is likely to affect browsing for users with small bandwidth. To know the loading speed of the site in detail, you can use the plug-in YSlow, which detects the loading time of web pages. It is an extension for Mozilla Firefox (download address: https://addons.mozilla.org/en-US/firefox/addon/ 5369 ".
After the plug-in is installed, open the website to be tested. When the web page is loaded, you can see a statistical number. Here is the detailed time data used to load the web page.
2. Small improvements make web page display faster
Use Gzip to compress documents: GZIP encoding is a method used to improve the performance of web pages, not only reducing storage space, but also reducing the time required for transmission. After using Gzip to compress the files in the website, the loading speed of the web page can be significantly increased, and the bandwidth consumption of the website can also be reduced.
Place the style sheet files for external calls: Put the JavaScript and CSS style sheet files that need to be used in the page in another folder, so that these called files will be cached when opening other pages of the website, thereby speeding up the website. Page loading speed.

Avoid using web page redirects: either through server-side redirects or JavaScript code that redirects content. The website will first load a blank page and then direct to another page. This not only prolongs the loading time of the page, but also may cause the page to fail to jump, leaving the user facing a "blank" page.
Eliminate duplicated and redundant scripts: Browsers loading the same web page scripts will increase the page loading time, but many programs will make this simple mistake. Now look to see if there are any jQuery or other scripts that are called twice or three times in the website.
Reduce domain name DNS search time: After the user types the domain name in the browser's address bar, the browser will search for the IP address corresponding to the domain name through the DNS system. You may need to set the DNS time to a lower level, such as an average of 60-100 Perform a DNS query every millisecond.
Reduce weight for JavaScript files: This method is different from the gzip compression function. There are many ways to reduce the size of JavaScript documents, such as removing unnecessary spaces and other tags. Reducing script files can significantly improve the access speed of web pages.
9. Tips to improve domain name PageRank
Pagerank, referred to as PR, is Google’s weight assessment of a website. Usually, the higher the PR, the better the quality of the website. Recently, Google's PR value has undergone a major update. For many novice webmasters, the desire to improve PR is usually very strong. Through this article, you can learn about the techniques to improve PR.
Usually the Google PR algorithm is that if a website or web page is linked to more times, the PR of this website or web page will be higher. In theory, if there are more links, PR will increase accordingly. Although PR is no longer a criterion for judging the quality of a website, many webmasters will pay attention to the PR of the website when exchanging friendly links or placing advertisements. And for a site with a high PR value, the number and quality of links must be higher than that of a site with a low PR value, so in a sense PR still plays a big role.
1. Increase the original content of the website
A website's original content plays an irreplaceable role in both user browsing experience and search engine inclusion. The same original content will also effectively increase Google’s PR value, so the PR value of most personal independent blogs is much higher than the PR value of websites.
For personal websites, providing valuable website content and conducting appropriate SEO optimization are also very important to increase PR value.
2. Clear invalid links and images
Reasons such as expired content and invalid links will cause various invalid links and images to appear on the website. If there are too many invalid links in the website, it is very likely to cause a decrease in Google PR value. Therefore, for common invalid links on the website, they must be removed in time when discovered.
3. Link to websites with PR
For most personal websites, generally a PR value of 4 is considered a good website, so when looking for friendly links, it is best to look for sites that are greater than or equal to PR4. However, it should be noted that many websites are now punished by Google for various reasons, resulting in a PR of 0. Therefore, you should be cautious when linking to websites without PR value.
Tips:
If you encounter a sudden decrease in the PR value of a linked website, you should also be careful, because the decrease in the PR value of mutually linked websites will also have an impact on the website.
Write high-quality articles for publication.
Nowadays, many websites have opened the submission function. When publishing articles on these websites, you can usually leave your own website link address. If the content of the article is recognized, the chance of being reprinted will be greatly increased, and the PR value will naturally increase quickly. .
Other well-known BBS forums can also meet the requirements, such as placing website links on the forum signature and then replying to posts, which is also a way to increase external links.
4. Submit directory and website navigation
For Google, website directories like Yahoo, DMOZ, etc. all have high weight. If it can be included by such websites, the PR value of the website will increase rapidly. Some high-quality domestic URL navigation websites are also effective in increasing the weight of the website.
