A few days before the May Day holiday, I found that MySQL errors occasionally appear when I open the website, but you can refresh normally. At first, I thought that there was a problem with the browser, but I didn't care about it. As a result, during the May Day holiday, QQ friends told me that my website could not be opened, and then I knew that it was really a failure. Previously, I used Win+iis, the Guardian host software. I had long wanted to change it to Linux, but I was too lazy to change it. It was too inky. I just took this opportunity to try again, but I encountered a problem of losing it. The website server was poisoned, which caused all the disk space to be occupied. The display was 0 bytes. It was impossible to check and kill viruses, and the software could not be installed, You can only back up and delete some useless things first. You accidentally find that every website
There has always been such a question, how much does website optimization cost? How to charge for SEO optimization? What is your SEO pricing standard and so on.

It is important to do things, and it is also important to be a person. In the process of work, people understand and see that a person who can work hard, help colleagues enthusiastically, and has good interpersonal charm is the success. 2.

I had an idea when I was working on the website. I wanted to add a "This website has been running safely for XX days" at the bottom of the website, but I was busy and forgot it later. Today, I checked the information and found that other websites had this tip, so I remembered to put the code on the website. If necessary, I can modify it myself and return it. The code is simple, easy and does not occupy any resources. The code is as follows: The html code is placed at the bottom of the website< a> This site has been running for<a id="days">0</a>days</a>The JS code is as follows: the code can be placed before</body>, and the time is your site establishment time (remember to cancel<scr

Today, I watched the Langya List. I saw that Hu Ge met Nie Feng in that episode. The acting skills were really gone. It was off the topic. Then I downloaded the video. But when I uploaded the space, I failed to find the Tencent video I just downloaded. The reason is that the video format is in the qlv format, so I used transcoding software to convert Tencent video into mp4 in the qlv format, but the software also failed to achieve... This is embarrassing. Friends who like to use Tencent video should know that Tencent video has produced a separate QLV format file, which can only be played using Tencent's unique Tencent video software, even if format factory conversion is not possible. I don't know if you have tried it. Baidu later found that the original QLV file of Tencent video can be converted to MP4 format, recording the transformation process; Tencent video ql
The working principle of search engine is a basic course that SEO practitioners should understand, but some people say that the working principle of search engine is not easy for novices to understand, because the working principle is too abstract, and the search engine is changeable, no matter who can really understand the working principle of search. What I want to say is that no matter how the search engine changes, the general principle of inclusion will not change: 1. Find the URL of the website and download the page. 2. Determine whether the page quality reaches the inclusion standard, or delete it. 3. Determine whether the included page is updated and update the page snapshot. The above three are the basic rules for search engines to include pages, and neither Baidu nor Google will violate them. Then we can explain the working principle of search engine in detail based on the above three items.

Recently, I was sorting out the mate tags on web pages, and I wanted to record the commonly used mate tags. Some of them can solve the problem of IE incompatibility. Now generally speaking, the lowest version of Internet Explorer should be IE8, but it is not ruled out that some backward computer machines are still IE6.7, so we should sort out the relevant data for backup.
