Web technology: eBay vs Taobao

In the past two months, due to work needs, I have made some research on Web-related technologies.SitePrevious practices. I think I have a little bit of experience [actually just got started :)].

Based on the principles of application, write this Blog to make a targeted analysis. SelectEbay (ebay China)AndTaobaoThis is right for competitors. The names of the two companies are listed alphabetically. The following "eBay" and "Taobao" refer to the Web pages of both parties without special instructions.

It should be noted that the "Web technology" I mentioned here is a narrow concept, and the content will be restricted inHTML,XHTML,CSS, Web Design, and search engine friendliness.

UseIEOpen their respective sites and look at them from the very beginning. At first glance, the two sites have a similar pattern-after all, they are competitors, and even the dominant colors are similar. Note thatTaobaoHomepageMain navigation barThey are made of images ("I want to buy", "I want to sell", "my Taobao", and "Community, the pictures do not look very beautiful either, especially when you move the mouse over the picture. Oh, it's not good. It's not very important to the image to use "Alt".HTMLMark. This is not very "friendly" for search engines ". LookEBay,Main navigation barThe processing is not bad, and it looks more comfortable. Of course, it is also made of images (interestingly, eBay's navigation bar can achieve the same effect without using images ), however, you can see the description of the image when you move the mouse over it (the image in the navigation bar is marked with "Alt ). From this point, eBay's page design seems a little better.

At the top of the navigation bar of the eBay site, I can seeSite map)I searched through the Taobao page and did not find this important site content. A well-developed site map provides reference for visitors and search engine robots.

As mentioned aboveAlt markNext, let's take a look at the image tags on the entire page of the two sites. Through the Pageinfo tool of Mozilla Firefox, there are a total of 80 images on the Taobao page (with a slight error), but only four of them are marked with Alt. EBay, 61 images, 14 Alt tags, but only 7 of the content. The other half is empty. The two pages mentioned here are for reference at, January 1, December 13, 2004. The test tool is Firefox 1.0.

I used Firefox for the comparison in the previous step.Display information in FirefoxHowever, eBay has a bad performance in Firefox: it cannot be displayed normally. Page deformation occurs. It is estimated that different browsers are not tested during the design, which also reflects the poor structure of the page code design. While Taobao's page is displayed well in the Firefox browser. One point.

Through the Pageinfo tool, we learned that Taobao's page code is "GB2312", while eBay uses "UTF8". From this point, it would be far-fetched to say who is better and who is better, however, we must be sure that UTF8 has better scalability, which is also related to the integration of ebay (China) and ebay.com some time ago.

Let's take a look at the two.SiteHTMLSource code. EBay's site source code, Oh, actually has a lotCSSThere, copying and pasting into The WordPad is actually as many as 1,693 bytes. This is a big taboo for a large e-commerce site! Think about it. If every page saves 1,693 bytes, how much traffic will be saved in a day? If every page needs to parse 1,693 bytes more, how much will it waste? At this point, Taobao can still handle the problem. The page does not display a separateCSSSection.
