SEO Practice (4)--seo friendly URL structure

The series of the previous two articles have almost all the ideas of SEO covered, as the beginning said, SEO is nothing but to search engine friendly, or to search engine user-friendly, there is no more. The next step will be to continue to mention some more detailed things. Because in the public environment of group Bo can share limited content, so will favor some and SEO effect may not have a direct relationship, but also should be SEO attention to the technical aspects of the content.

For SEO, what is a good URL structure? Like the previous article, let's look at the SEO top site Amazon's approach, which is a product page:

Http://www.amazon.com/Zune-Video-MP3-Player-Platinum/dp/B002JPITY8

1.

The first paragraph of the URL is the product name, with the underscore separating--google the symbols recommended in its webmaster tools help (slightly similar, Baidu search engine friendly Guide to the proposed page title and site name separation between the best is underlined.) Of course, these are not related to the search engine identification mechanism, they may not be able to recognize these are delimiters, but for the user will be relatively friendlier. )

2.

DP, perhaps referred to as detail product, is a special identification of the products page. As long as there is a URL in, whether in the flow statistics tool or log analysis, can be very convenient to the product type of the flow of the page to subdivide.

3.

B002jpity8 This is the product of the ASIN code, for each product this is unique, so as to ensure that the product will not repeat the release. Is the unique identification of each product.

But such URLs also have some problems, such as access: http://www.amazon.com/abcdefg/dp/B002JPITY8 such a URL, will also appear in front of the same page. In case these pages are indexed by search engines, at least it is no good for SEO. (Do not rule out a few cases where competitors will use this to frame their own website seo possibilities)

So what is the technical solution? If you ask a program person, they might give you the option of reading the first paragraph of the URL when the page is requested and comparing it to the name of the product. If the match is returned to the normal page, or throw 404 exception.

But SEO has a better solution, directly output a canonical attribute to specify the URL of the specification is good, Amazon is doing so. This is a label used to handle Web site normalization, which is explained in Google Webmaster Tools help: Http://support.google.com/webmasters/bin/answer.py?hl=zh-Hans&answer =139394 (and Baidu does not support canonical label I am not sure)

But Amazon does more than that, for the URL of the third paragraph of the Asin code, there are other mystery in. This is a short section of the Amazon official's description of ASIN code:

You'll find a item ' s ASIN on the product detail page alongside further details relating to the item, which may include Information such as size, number of pages (if it ' s book) or number of discs (if it's a CD).

The main idea is that many of the key parameter information for the product is recorded in this short asin code, so that the data analysis can be used to determine what kind of products sell well and so on. And the encrypted Asin code also makes it impossible for competitors to get their information easily.

A combination of some of the mentioned, and other limited space has not mentioned the factors, here will be the URL structure in SEO inside the additional need to note the general importance of the list:

1. Uniqueness (Guaranteed page cannot be duplicated)

2. Easy analysis (up to a simple regular will be able to subdivide a class of pages, can not be the best of the words)

3. Semantic (such as example.com/blog/1.html, example.com/gallery/2.html, so that users can only look at the URL to know what kind of page they will visit)

4. Efficiency of the procedure

It's impossible to say that the URL structure is absolutely perfect. Depending on the type of site, size, and so on, it is also necessary to see how the technical framework of the Web site more convenient, and may also need to refer to the needs of various other departments, the final form of the URL is naturally need to weigh the pros and cons of various aspects to come out, this side is not
