The following paragraph is recorded in the experiment I have done, the reason for the failure of the experiment is too urgent, do SEO patience is very important, can not be anxious.
January 27, 08 on-line format conversion Online line three months, Gg,yahoo included normal, Baidu has been confiscated. Baidu is not included in the possible reasons:
1, is the keyword "conversion" density is too high. The entire home page looks like the word "convert" appears frequently. Using tool detection, the word "conversion" density is: 6%. The term "format conversion" has a density of 2%. Also within the normal range, not too high.
2, the server IP was punished by Baidu. There are several stations under K, may affect the new station included.
5-20 to improve: Reduce the first keyword density. Submit the website to Baidu again. 2008-5-29 Baidu received 11 pages, are content pages, the home has not been included. Index time for 2008-2-13, that is, Baidu in the Web site about half a month or so included, but has not been shown. Yesterday the website has through other key words to the IP, but today these few pages did not appear. Still in the adjustment, continue to observe. 2008-5-31 to adjust the title of the home page, wrote a comparison to summarize the content of the title of the site, in each content page added a javascrip code.
Analysis: The homepage has not been included, may be the keyword density is a bit high; In addition, and the server on other sites are punished, the site in Baidu's weight is relatively low. A little change will be completely k off. Conclusion: The stability of the server and the quality of the above site is the basis, the new station will also be implicated. In addition, the new station optimization should be natural, in the short term do not make too big adjustment. Search engine on the Web page has an inspection period (at least half a month), if just included on the adjustment, more dangerous. Of course, the adjustment here refers to changes in the Web page title,discription, and other optimization methods, the appropriate update content on the search engine or friendly performance. Recently made a page also proved this point, in one of my download station added a page, used to observe the ranking of keywords, put up later, the next day was included in GG, a few words ranked about 2nd, 3, 4 pages, the third day, one of the words ranked to the first page, this time I made adjustments to the page , the title of the appropriate repetition of a keyword, is repeated two times, the content of an important word added H1 tag. Think of the adjustment after hundreds may have better performance, did not expect the fourth day page in GG can not find.
The effect of SEO needs a process, patience is very important. In addition, the study of the people do not care too much about the results, success has successful experience, failure has the lessons of failure, do have a harvest.
