Not clear this series of test content friends can first look at the following article, "Search engine treatment Jump code series test Trailer" http://yihuiblog.com/a/18.html.

Test observation of the main target for Baidu and Google, the test page will be permanently retained, convenient to observe later. Let's review the three sets of tests first, and the third group will be added on April 10.

The first group: divided into pages 1 and 2, test the search engine is how to treat and identify the normal HTML page jump. The method is to add the following META tag code to page 1 and jump to page 2:

<meta http-equiv= "Refresh" content= "10; Url= Jump Results page Address ">

The second group: divided into pages 3 and 4, testing how the search engine treats and identifies JavaScript jumps. The method is in Page 3 plus the following JS jump code, jump to page 4:

<script language= "JavaScript" >
var the_timeout = settimeout ("location= ' Jump results page address '", 10000);
</script>

The third group: divided into pages 5 and 6, test search engine is how to treat and identify the jump from the JS. The method is in page 5 plus the following part of the Outward JS code (the outward JS contains jump code), jump to page 6:

<script src= "http://yihuiblog.com/qita/ceshi/tiao/5-2.htm" ></script>

Take a look at these three sets of pages before the collection. Google, the beginning is 1, 2, 3, 44 pages are included, and then deleted 1 and 32 pages. Later to the third group, until now are only included in the 5 page, although Google spiders have climbed over the 5-2 of the outward JS.

The log code for the 5-2 page capture is as follows:

66.249.68.198--[19/apr/2011:07:01:44-0700]
"Get/qita/ceshi/tiao/5-2.htm http/1.1" 200 153 "-"
"Mozilla/5.0 (compatible; googlebot/2.1;
+http://www.google.com/bot.html) "

At present, the three groups of test pages, Google included 2, 4, 53 pages.

Baidu, the host log showed Baidu Spiders climbed 1, 2, 3, 5 of these four pages, but now from the results of the site, only included 2, 3, 53 pages.

Well, finally wrote the summary part of this series of tests, it is estimated that long we see dizzy dizzy.

This test has tried to avoid the search engine from other places to get the jump results page. 10,000 step back, by the search engine from other places to get the jump results page leading to capture the index, even if the "recognition" test part of the failure also left "treatment" part of the test.

The first group of test results: Baidu and Google can be very good to identify the normal HTML page jump, but also as a 301 redirect effect, not included Page 1.

The second group of test results: Baidu aspect, even if the page inside the JS code, will not go to analyze and link to it (page 4) capture. Google is different, fully identify the page inside the JS jump code, but also as a 301 redirect effect, not included Page 3.

The third group of test results: Baidu and Google did not analyze page 6 to capture and index. The only difference is that Google will catch the outward JS page 5-2.

This series of tests is believed to inspire many people. Of course nothing is perfect, and this series of tests is no exception. Welcome to discuss the exchange and share the experience of this series of tests.
