Intermediary transaction http://www.aliyun.com/zixun/aggregation/6858.html ">seo diagnose Taobao guest cloud host technology Hall

I a wooden door website, is the enterprise website, the content is relatively simple, the total page may only have 200 pages or so, October on-line, the specific time remembers is not clear. December 31 Update after I check PR, incredibly is 4, I am very puzzled, how so fast, from 0 direct to 4!

For this, want to ask friends, in the end is how the matter? I 211.html "> think is not the PR is not any use, otherwise the sky will not drop the next Lin sister to me."

In this period, I purchased a few PR7 and PR5 chain, perhaps this is the most important reason, I think, if it is so simple, the PR value is too no meaning, buy a few PR7 chain also thousand yuan, too easy.

The site itself we are relatively few upload articles, because there is really not much to write on, the company's website, where so many things happen ah? East copy a little, West copy a bit will reduce the quality of the company's website, would rather not write, disorderly writing to distributors and customers are not good things. I checked the record, Google also included 200 articles, Baidu only 67, quite a few.

There is a bit more puzzled me, Baidu and Google on my wooden portal site keywords are not good, just on the first month of the online has several important keywords are on the home page, recently dropped. We still have to promote the site, such as the keyword to buy Baidu, but also in Alibaba on the wisdom on the purchase, but also in a number of investment sites posted on the information, done outside the chain. The information of these major stations is collected by Baidu very quickly, and the ranking is also very good, I concluded that Baidu is not interested in my small station, so the keyword ranking will not be good. --I hope the professionals will analyze it.

From this station 3 months of performance look, have the following questions, if you can get advice, will be grateful:

1, PR refers to the significance may have been little, even can say PR value has become yesterday;

2, Baidu's keyword ranking of the site may have not been as stable as before, the basic will not let a certain site a key word for a long time to maintain a good position, after all, Baidu is mainly rely on ranking to make money;

3, Baidu's collection of stations far better than the station.
