I have to say that we are not fully prepared for the site change, and I have to admit that Baidu's response to the 301 redirect is so fast. I used to underestimate the efficiency of it, and see Baidu is also in constant progress. But this progress to me caused unmatched pain, the company's website can also be said to have been subjected to se punishment of the blood-light disaster.
Last Friday, due to the server space, the company's website changed the site space, it is the weekend, the technology desperately to the site source code, upload and so on a large pile, are for the weekend to have a good rest. I am responsible for website SEO aspect, the website uploads to the new space after not any question, I want to just change the space, the processing speed is very fast, should have no problem. I'm going to get off my butt.
Back in the evening of Saturday, the habitual site,domain looked at the situation of the site, the results scared me a big jump, site: Web site, when the home page disappeared, I was a monk. Which paragraph is this for? site several times or did not see the home page, check the next Baidu weight and included entries, all can not find rankings, ranked in the back of 108,000! At that time my first reaction is: "Finished, was Baidu K, will be scolded by the boss death!"
No way, something happened to find the cause of the remedy it, who called us is the operation of the Commissioner.
I mainly from the following aspects of diagnostic analysis:
First, the first consideration is of course the reason to change the space, but, I checked and our company's website to replace the other site is completely without this situation, so this reason is not tenable. (In fact, the change of space will not have such a big impact, even say the impact can be ignored, this is my experience).
Second, check the links, because this is the reason for the more conventional. But carefully checked the next link, did not find any problems, exchange links of the site are regular websites.
Third, since the space and friends of the chain are no problem, I did not have the idea, domain command checked the chain outside, found that the chain is normal. Not diminished. What kind of reason is that? Baffled explanation, suddenly remembered is not to add three W of the homepage will also k off? Good, immediately Baidu check, but found no three W home page just good in Baidu!
What's the reason? Didn't add three W homepage no problem? Is it the 301 jump problem?! Check the HTTP status immediately, the result added three W and the page without three W is the return status code: 200. Is this the reason, by all means 200 of the state will not be k off AH?
I suddenly think is not before three W 301 jump to the WWW address? And now there are no jumps are bound to the company's Web site? (Before the domain name how to parse and bind I do not know). Call technology, as I expected, before the three W domain name is done on the server IIS 301 permanent redirect jump. Here I'm not sure it is because of the 301 jump to let the company homepage bad Evil, and I asked the technology, that another site (and the company's website to change the station of the server) is also to do 301 jump? Technical answer said that the station did not do 301 jump, and it's not add three W domain name does not bind the site directory at all. In this way, one-to-one comparison, I completely decided that the company's home page snapshot was deleted, the key word ranking sharp decline is the real reason is to replace the space did not do 301 jump!
After the reason found, I did the following simple work: Speed to the three W domain name 301 Redirect to three W of the company domain name, keep the same resolution and binding as before changing the space; add a few Baidu weight in 2-4 of the chain of friendship links, write a few original articles posted on the top of the homepage, do 10 or more home page outside the chain; Then I prayed that tomorrow would be better and tomorrow's boss would not be able to get me.
Although I can not confirm now, find out why I do these remedial work will immediately effect, but from this thing I understand that the site space no trivial!
Here also call and remind the vast number of Web site operators franchise and webmaster, pay attention to site replacement space after 301,302 page jump problem, we must connect well, do not do before 301 jump, to the new space will become 200. I take our company website now the miserable encounter tells you, this absolutely impermissible, if you must defy the word, next time writes the feeling after the abuse is you!
Well, unknowingly written after the feeling of abuse can not stop, there is wood to the funeral, please pay attention to my article or focus on Sina Weibo @ Shenzhen World Wide Web, I will continue to report the site by K after the latest progress.
