I haven’t posted an article on Webmaster.com for more than a year. It may be due to time reasons or because there are no issues to discuss. Basically, any problems encountered can be solved. But recently a buddy came to me and said that he encountered a problem that he couldn't solve. He built a corporate website for punch presses at the end of last year. The key keyword was "punch press" and it was naturally ranked in the top five in the first few months of this year. Before being demoted, it was ranked first for quite some time, as if it was a comeback, but then suddenly it disappeared when searching.
When entering the URL www.jhpress.net and searching directly on Baidu, it will display as follows
In other words, the update was updated 20 days ago. When entering site:jhpress.net in Baidu, a total of 17 internal pages were included, but no home page was included at all. In fact, I have experienced this kind of thing before, but after adjusting the keyword density and adding links, I adjusted it in three to five days. I'll be back in ten days at most. In fact, he found me because he saw that I was doing very well with websites in the same industry as him, so he found me, but he didn’t know me. But judging from the other sites he built, they were very successful. When I saw it, I made a rough analysis. Baidu did not pluck out the hair on the homepage of this site, but directly lowered the weight. It was not an ordinary reduction, but basically entered the key The word cannot be found. Personally, I think the possible reasons are as follows:
First, the keyword density is too high, but he said it has never changed. Even the title is the same as when he first started building the website.
Second, the space domain names are all from Xinnet, and those without WWW cannot be resolved. It may have something to do with this, because I usually use the good double-line spaces from the folk. He just changed the space to double-line spaces. I don’t know how it works.
Third, the entire site has no external links. Now it has added one from Baidu. However, it ranks quite well in other search engines such as Google, Sogou, Youdao, etc., and many words are in the top ten.
I believe that many people who do business website optimization have encountered this situation, and some people have successfully solved it, including me, but this time it has been a month since there was any change. I don’t know if there is a better solution. Solution, I hope experts can give me some advice. This is also an opportunity for many grassroots people who have encountered such problems but have not solved them.
