Discussion on the influence of URL parameters on search results

Read the title, we can not see it, because a little seo people know: The fewer URL parameters, Baidu and Google's website Optimization guide are clearly stated in this point. And then in practice, it's not necessarily the case. Here's what I've stumbled upon:

　　

Baidu Search "dhc120ml" results

　　

Google search "dhc120ml" results

Compared to two pictures, we can find that Baidu's search results of the top three, from the more authoritative large sites, such as the United States, Alibaba, Baidu Open platform, and so on, Google's search results in the top three are from Taobao. Wait a moment, did Taobao guest of Google search results of the second and third familiar with it, yes, that is with Taobao customer PID promotion link.

What is Taobao customer PID promotion link? In general, Taobao customer PID only tracking the promotion of merchandise information, remove the PID promotion page and no change, then that is, PID is optional, for search engines. From the description of Google Spider and page preview, two pages exactly the same, then I can boldly speculate that Google in the URL meaningless parameters of the screening, there are some defects. and Taobao shielding Baidu Spider, so can not see, Baidu is able to identify meaningless URL parameters (I will do this in the future to do a certain test).

From this I thought, do Taobao friends may wish to try, with their own PID Taobao customer promotion link to Google, while getting more traffic. But this is just speculation, and in practical applications, we should be careful to avoid:

1, the use of too long and contains extraneous parameters and session ID URL;

2, use too summary of the page name, such as page1.html;

3, the use of excessive stack of keywords, such as baseball-cards-baseball-cardsbaseballcards.htm.

Because the search engine changes every day, so try not to opportunistic and therefore be punished, that would outweigh the gains. Again on the URL processing, I run the Mongolian Search brand network www.mengxx.com, is to minimize the parameters to the least, but in the processing according to sales and popularity ranking is also very headache, have a good attention of friends, can communicate with me.
