Why do not industry sites get a good ranking?

I have also built several industry websites, are highly targeted product sites, but has not been able to get the favor of Baidu, one of the Web site, upload the first day, half an hour was Google included 17 Page, I feel very lucky, of course, I built the site is based SEO skills to optimize, but Baidu has only included a home page for half a month so far, and Google almost all my pages will be included in the case, a total of included 67 pages, the two search engines included so much difference, I made the following analysis.

First, the home page is not easy to large-scale Flash animation appears, but the lack of text description of the necessary content is very difficult to crawl further Baidu crawler, in particular, the home page of the site has also been linked to Flash, leading to the home page has become Orphaned, so Baidu has only included the home page, without further included home page under the directory.

Second, the site for the first time to Baidu included, get a good ranking, a large number of repeated piling keywords, long tail keywords and other excessive optimization methods, resulting in things the opposite, because Baidu adopted the website quality control technology , A large number of over-dense keywords, the quality of the web page, the weight is reduced, and even some of the site keywords and web content has nothing to do, so can not get included in Baidu, even included, is not good.

Third, the site uses too many Java syntax and dynamic effects, these elements can not be identified by Baidu, especially in the top of the site can not appear too much Java syntax, because the site above the basic structure nothing more than "company Logo "+" company name "+ big banner pictures, these structures are generally used pictures or Flash animation effects, Baidu snapshots are not up; and in these structures, our site is followed by the Java statement , The reference framework, such sites tend to look good overall appearance, but Baidu is not flattered, too many Java, pictures, framework is one of the reasons for rejection of Baidu in the door, Baidu included as unsuccessful, the most important is There is no place to start snapshots, Baidu snapshots are generally the top part of the site, too much mess will affect the Baidu snapshot analysis and time, thus giving up the entire web site or even.

Fourth, the content of the website is not new, stereotyped Copy, even their own product content is copied on the success of the content on the site, everyone knows, so guilty of Baidu Taboo, can quickly search online product information, are with A certain weight website, I believe you find the product content will not find the eighth page of Baidu, the tenth page to go, that is, the first three pages, the contents of these pages are Baidu spider hard to find out, your A copy of most of Baidu is considered a repost, it does not have much meaning. Therefore, the best content to write their own website, not original, but also to modify other people's information, become their own original.

Fifth, the site must be stable space, I have personally experienced before, once my space was inexplicable seconds of the site operators turn off, and a few days or until I discovered that the site was opened to inform operators Baidu has a very good ranking of the site, what once fell to the top ten range, and the included pages also decreased a lot, so a toss took me six months to double the time before recovery.

The above five points on the new station owners friends have some help, especially for the website of industrial products, more rankings skills analysis will not be described one by one.
