How can I re-include the website to baidu when the website is K?

On the 1949th, my website was hacked. At that time, my mood was like the bottom of the ground. But I still said that if I had no Baidu, I couldn't help but do it?
Therefore, we will continue to update and maintain it every day. But another thing is to study why K is used. At that time, I saw a lot of Webmasters like me on ADMIN5, all of which were K this time. They also combined some SEO knowledge and came to some conclusions:
1. Rename: I changed my website name to "Shanghai Free Resource Network" when my traffic was rising steadily ".
Suggestion: do not use off-the-shelf popular keywords for website names. Now I have switched back (www.111cn.net)
2. My traffic reaches 6000IP. Among them, Baidu's traffic is about 5000, and some keywords are still in the top three, such as "online production of QQ portraits". I guess it's where I open a knife and listen to other friends, the keyword of his website is K at the beginning. Please refer to this number. This is assumed 2.
Suggestion: Do not optimize keywords, which is counterproductive;
3. My optimization is not good enough and Baidu regards it as a waste station. Suppose 3. I think this is very unlikely.
Others: at present, Baidu's algorithms have been further changed. The top 50 optimization method is outdated, and the weight of keyword integrity in SEO has dropped a lot. That is to say, Baidu's spider has become smarter over the past month. Haha.
Now I try again to make a new site, and it is much harder to optimize it than before. The reason is that Baidu, over the past month, looked down upon the station and the new station and did not give you a better weight.
Countermeasure:
1. The new station must have traffic. No matter what method you use, you must inject traffic to the new station. A rich webmaster can buy traffic, and a technical webmaster can put a horse on his/her own. If there is no money, the webmaster will surely get ALEXA up. When the ranking reaches about 0.1 million, Baidu will pay attention to you and patronize you every day. It will give you the weight and traffic. Many believe that
Ranking has nothing to do with Baidu, but according to my observation, there is no authoritative traffic statistics in China, Baidu is very likely to judge the website traffic based on ALEXA, determine the full weight of the website in sequence.
Weight refers to the level that Baidu defines for your website and the factor that gives the keyword ranking. For example,
A: If Baidu thinks your website is good, it will rank you in front of similar websites;
B: If you and a website have optimized a keyword at the same time, if your weight is the highest (expressed as 1), and your website has a weight of 500, you will be the first in this case, the number of stations is 500th. Generally, the weight of a well-known website is high, and the weight of your website is low. This is why we cannot directly optimize the extremely popular keyword "QQ. So what key words should the new site optimize to compete with the big site? Many webmasters will tell you that since "QQ" cannot be optimized, you can optimize "QQ expression", which is a medium popular keyword. Error. This already has 1 ~ A keyword that can be optimized for a website with 20 thousand traffic. The new site is not qualified to optimize it. Station 1 has no traffic, and site 2 has no name. Why did Baidu optimize it? If you want to optimize the "QQ expression", there are only two results. 1. Hard work in white. Because your weight is too low, only 50 pages of "QQ emoticons" can be searched by others on Baidu; 2. If you think you are cheating, you will be blacklisted, since then, Baidu has no more websites.
Optimization is to estimate your Baidu weight based on your current traffic and ALEXA ranking, and combine the popularity of the keywords you selected, subscribe the keywords, and then determine the keywords that suit you.
Package and push it to the engine. In this way, the optimization is successful.
2. Be original and keep updated. Originality refers to originality in the engine eye, not true originality.
3. Improve external connections. Welcome to the theft method and take the initiative to send out the friendship method
4. Create a strategy for returning customers. The controversial content of the website atmosphere seems to be unique to me
5. Shoot a bird. Low-key strategy, cost-effective, and money-making strategy
A little messy, hope to understand!
