Ii. Duplication of diagnostic titles and descriptions:

As shown above, all page titles are known as harbin industrial university, which is the same for users, which has a strong influence on browsing and is detrimental to the distribution of weights between web pages。
As opposed to the description:

Iii. Uniqueness in diagnosing urls
Url uniqueness, also known as the preferred field, refers to the process of selecting the best url in several urls, which usually refers to the home page. The first page of a website is usually accessed by several different urls, such as www. 51yunying. Net and 51yunying. Net
One with www, one without, can be accessed for 51 operations, but the algorithm for the search engine, which is two pages, is randomly selected as a ranking object at 100 degrees. Which one to choose? He thinks the top-weight page, so we need to determine a preferred domain name to optimize and increase the weight of the preferred domain name。
How do you know the preferred field? One is to unify the links to www when making internal and external links. The second is the re-orientation of 301, which can be redirected to the new site by accessing a web site, using a re-directional approach, by automatically jumping to a web site or domain name that we have specified, or by applying to a site re-version。
Diagnosis of url levels
The url level is the depth of the url, and the more it is, the deeper it is and the more complex it is, the slower the page opens, the harder the search engine will be。
There are three slashes on the page up the chart. The average search engine will be on the 3-4 floors at most, so we'd better keep the u. R. L. On the 3rd floor or it'll be hard to get him。
V. Diagnosis robots documents

Usually open-source station programs automatically generate robots files. We just need to look at what's inside. The user-agent:* in the document indicates that all search engines are allowed to record it, disallow: /admin/ states that the search engine is not allowed to capture the contents of the folder of admin, and that if this document is not available in the root directory of the website, we can upload it ourselves。
Vi. Speed of updating diagnostic snapshots
Keep the site up to date, and every time the search engine comes to your site, it finds it different from last time. We can do this through regular updates of articles, but if the pages cannot be updated, we can build a web-based blog to update content, add a comment function to the article, add comments to the article, and add related articles, the latest articles, so that every time the website is updated, the entire site page is updated。
After these six diagnoses, our website can go online in a healthy way。
