generalities SEO optimization, website optimization, page optimization layout and analysis, all in our seoer mind formed a sense, the site ranking is our Seoer the most concerned about the matter. Usually we often say is through the analysis of Baidu related domain and included, Yahoo reverse link and PR and so on to analyze the weight of our site and the quality of the site. If there is something wrong with our website, we do webmaster's most concern is that our site included, the relevant domain and reverse link changes, here I want to share with you the IIS log analysis, the following simple by me to analyze how the IIS log to trace the analysis of search engine spiders.

IIS (Internet Information Services) log is a function of each of our sites, but most of our webmaster do not care about it, there are some webmaster space may not have IIS log function, This requires you to find your server provider to help you open the IIS log function, only our space has such a function, after the spider came to our website the dialogue with the server will be recorded in the IIS log, we through the analysis of IIS log to know what spiders have done to our site, Crawled and included in our pages, including spiders to our site's crawl times and address, which are spiders like to crawl, which is not like spiders or can not crawl to the page, know these we can for spiders crawl trend to better analyze and optimize our website page, More clearly our site in the search engine dynamics, so how do we analyze IIS log?

This code is found in the IIS log 61.135.168.22-[11/jan/2009:04:02:45 +0800] "get/bbs/thread-7303-1-1.html http/1.1" 200 8450 "-" " baiduspider+ (+[url]http://www.baidu.com/search/spider.htm[/url]) "Through this piece of code to analyze the crawling of spiders."

First, we need to know the name of the spider, which spiders will come to our site crawling, here list several more common spider name, Baidu->baiduspider, Google->googlebot, Msn->msnbot, Yahoo-> Slurp, Yodao->youdaobot, Sogou->sogou+get+spider in the log file, search above spider name. You can see the traces of spiders crawling.

Second, look at the spider's IP address, this is not much use, we know on the line, IP address as usual when we use mobile phone to your friends on the phone when you call your friends, your friend on the phone will show your mobile phone number is the same truth, spiders are the same, It comes to your website and uses an IP to display its "mobile phone number."

Third, the spider to our page access time, the above section of code [11/JAN/2009:04:02:45 +0800] tells us that the spider through the 80 port on August 11, 2009 04:02 45 seconds to visit our page.

Four, spiders come to our pages, get/bbs/thread-7303-1-1.html is the spider come to our site to reach the page.

Five, spiders visited our website, whether a certain visit to success and download our page, 200 8450 on behalf of the spider to visit the success and download the size of the 8450 page, here 200 means that the success of the visit, but not necessarily will be included in our page, said 200, Then someone would ask, "what's the same HTTP status code like 301,302,304,400,404,500,503 and so on?"

200: page access is successful but will not necessarily be included in the download

301: Resource Permanent redirection

302: Resource Temporary redirection

304: The page has not been updated, the spider came to our page after the discovery of this page I have come before, this time to find this person on the page content is exactly the same as the first time, IIS log will return a large number of 304.

404: Access to this link is the wrong link. This error link, on the one hand from the original existence later deleted the page, on the other hand may not exist, but other people outside the chain of such a dead link.

As for the 400,500,503 is the problem of the server, and our own page is not any relationship.

The above five points are the IIS log analysis that we often see, through the analysis of such IIS log code can clearly know what our site is doing bad, which pages are doing very good, so analysis can be more convenient to optimize our website, improve the conversion rate of our site.
