The IIS log is one that every seoer must learn to view, and the server's status and source of access to the IP are recorded in the IIS log, so the IIS log is very important to each Server Manager, which also makes it easy for site managers to view the site's operations. Web site plus business software can always detect a variety of IP to traffic, but search engine crawl web site information will not show up, this time we want to understand the site's information to see IIS log, it can reflect the site in various times different state.

We observe the IIS log every day can draw the status of our site, and then according to these states to make corresponding adjustments to the site, so that the site to achieve the best state, in fact, the search engine on each site will not directly reduce the right to start, there is a notice, first of all the keywords ranking drop Snapshots are not updated and so are search engines on the site down the right of the notice, if we do not observe the IIS log, we can not make an accurate judgment, and the IIS log is to record these, is not the search engine spiders are less, is not the site information has not been modified, or there is a dead link, None of us can get a conclusion from the Web site, and the IIS logs present it to us. Checking IIS logs every day can help us understand the status of the website, make an accurate judgment, make efforts for the increase of the weight of the website.

How to analyze IIS logs

After we have the IIS log, we can use the IIS Log Analyzer tool to check the IIS logs roughly. General tools can detect a variety of spiders come to the total number of sites, as well as there is no failure, will not give all kinds of information to you. It's not a tool analysis. We don't need a single one to look at, tool analysis is simply to tell you have no failure, no failure of course is happy, but to be a piece of analysis. We take a message like this to analyze

First time: 2010-10-22 05:04:53 The machine number is w3svc151800 p-0ymr9ww8yx4u9 222.76.213.49 is the website IP get is the trigger event, 80 is the port number, 61.135.186.49 is the spider's IP, Baiduspider is Baidu's spider, 200 0 0 access success, 41786 193 6968 is the spider's time to talk to the website and download the data as well as how much time it took. It's 2010.10.22 morning 5, 4 minutes, 53 seconds. A spider named w3svc151800 p-0ymr9ww8yx4u9 through 80 ports to enter the site successfully accessed and downloaded 47186B of data, cost 193MS.

Baidu's spider name: Baiduspider, Google spider name: Googlebot,

IIS logs are basically like this, except that the top one is successfully crawled: 200 0 0

404 (Not found) the server cannot find the requested page

304 (not modified) The requested page has not been modified since the last request, and the server does not return the page content when it returns this response

503 (Service Unavailable) server not currently available (due to timeout or downtime maintenance)

301 Permanent Redirect

302 Temporary redirection

Basically we want to understand is these FTTP status code, if your site appears 404, then you have to use a robots to screen, 404 is dead link, if there are 404, search engine will think you deceive users, will punish you. A large area of 304 will be noticed, the website has not updated, one or two relations are not big, but many will let the search engine think your website No person manages, the time will cause the website snapshot not to update, the keyword fluctuation; there are 503 that you cannot solve, and you will have to find the server provider. If it is in a row at the same time 503, I suggest you to change a server, because he at that time to judge the server causes spiders into not to go, spiders can not enter your site, search will not understand, will reduce the trust, down the right also began. 301 is permanent redirect, is the site changed use, can judge from here your 301 how to do, success did not. 302 temporary Redirect, when planning what activities can be used, for example, now Christmas is coming, many businesses are playing activities, you can use 302 temporary redirect past, after the festival to restore.

To observe the IIS log there is also an important place to observe the average spider, to one weeks for a cycle, the total number of spiders is increased to show that your site's weight is increasing, if this week's average is 5,000 times per day, and the next week is 7,000 times/days that means your weight is increasing, If it is down to 3,000 times/day that is the weight is falling, pay attention to see where the site is a problem. Also observe when the spider activity is more frequent, in the spider activities of the frequent update is conducive to the weight of the site increase.

Spiders on our site to crawl the URL address we also want to analyze, to see which web page spiders are more like, to which web crawl less, so as to analyze the site to modify the place, so as to make fine-tuning the website. As a seoer must analyze the IIS log, preferably every day to take time to analyze the IIS log, the fastest solution to the problem of the site, such as a 404 page, you get from the IIS log in a timely manner with a shield can only take effect in 48 hours, If it is to let Baidu crawl this URL address that will take 2-4 weeks to take effect, such a time wasted too long. So we have to observe the IIS log every day, if it is a large web site, spiders are more frequent, then the IIS log in one hours, divided out after a careful analysis.

The IIS log can help us to observe the website situation constantly, do seoer must analyze IIS log, can make the correct plan for the website, let the website thrive.
