Webmaster, why is your site reluctant to include? content to do the quality is high enough, outside the chain to do is also very strong, but why some of the links will not be included? This A5 optimization team (http://www.seozhenduan.com)/Heguijiang in this announcement:
One: url character length
URL is an important factor in the impact of Baidu, the common URL is divided into 3 types, first: Dynamic link, second: pseudo static, third static links, which remove the first, the other two are more conducive to search engine crawling and ranking. In these three, there is a common need to diagnose the problem, url link length:
Above, is the A5 optimization team of a diagnosis case, its own Google PR value of 6, even if Baidu also has a higher weight, the third party data show "Baidu Weight" for 5, although not authoritative, but overall still can see a good weight. But is such a site, in the home page impressively has some links have not been included. Why? In fact, according to a variety of statistical analysis, URL length will affect the search engine index. So we always recommend that webmaster optimize the site as much as possible to simplify the URL length to ensure that the search engine is well included. A5 Optimization team that: the site URL link length as far as possible to stay within 70 English characters.
Two: URL structure depth
The general site consists of three parts: "Home page, channel pages, content page", so the URL format is more statistics, the root directory, channel directory, content page. For this, is the most suitable for search engine crawling link structure. Others, however, are: "root directory, channel directory, child channel directory, date directory, content directory" Of course, this is just an example, but also:
"Http://www.***.com/xt/guochanju/10436/2022.html" It is obvious that the URL depth of 4, but the problem has come, so deep, users click on a page, basically going to climb 4-tier directory. In the search engine view, basically will think: the website deceives the user clicks. Of course, there is no absolute, in general, if these links can be displayed on the homepage, search engines will be included in a lot of good, and if not in the home page display generally speaking: are two level depth, or up to three level depth, and four depth we will not consider, many webmaster did not realize this, so that the weight of the site is low.
Three: URL error orientation
SEO optimization, most of the site will be 301 redirect, will be the top-level domain name with "www" World Wide Web domain name, in order to unify the weight, improve the ranking of keywords. But there are always some webmaster error 301 redirect, such as: Made 302 redirect.
and 302 redirects, although they can also play a directional effect, but the result is completely different. 302 Redirect, for temporary redirection, the search engine will think the site URL address will change their mind at any time, so the weight will not be passed. At the same time: the search engine in the crawl old station, the fact is to crawl to the content of the new station. As a result, the new and old stations have the same content is indexed, this is the formation of "repeat content cheating", affecting the normal search engine ranking order. The end result is the site is down right.
The second part of the webmaster will be the root directory of the first file orientation, such as:
The final result is to visit the site's main domain name, but will still form a jump, and is 302 of the jump finally:
A website that forms two addresses, the first weight is not centralized, but also for the site to increase the risk of reducing the right, so we have always recommended in the optimization of the webmaster: the definition of the default home page, rather than through the targeted access to the home page, at the same time our home page URL address do not add "bread crumbs."
