For each optimization staff need to have a certain degree of analysis, analysis of the user's search behavior, analysis of the site data flow and so on. Only a reasonable analysis of these data can better formulate our optimization strategy. One of the indispensable in our analysis of the site is to analyze the search engine spiders crawling behavior. Search engine spiders are invisible to our eyes, how do we analyze its crawling behavior? We can analyze our site's IIS logs.

One: Then from the analysis of IIS logs we can get information from our site

1: In the construction of the outside chain we know that every outside the chain is the search engine spiders enter the portal of our website, in this we can observe the log of the spider's visit, you can see from another perspective of our external chain can better attract spiders, in order to develop a more rational strategy for the construction of the chain.

2: The site of the space problem is a lot of webmaster thorny problem, the site can not open very likely to make our site overnight back before liberation. So for our site, how quickly the earliest understanding of the discovery problem. The same can be analyzed in the log search spider crawling situation, because the site space in addition to what the first response is the search engine spiders.

3: Through the log we can also analyze the spider for the page content crawling situation. Learn more about what the search engine likes about our site. We can according to these data in the content of the layout or fine-tuning, is the search engine more love our content.

Second: How to obtain the IIS log and the IIS log settings for our site

First, our site space needs to support the log downloads of the site. For this we buy the site space when you can first consult with the space business, whether to support the function, if supported, general log files in the weblog file, we can directly ftp to local. For the logging settings of IIS logs, I think generally if the site more content, more complex structure can be set to generate one hour, and less content can be set to update once a day, so that we can avoid the IIS log of the problem of large letter files.

Three: How to analyze the IIS log of our site

1: Split analysis of IIS log files

We use FTP to download the log locally, you can open the file through Notepad, while searching for the main search engine spider name, which Baidu's spider named Baiduspider, Google's spider named Googlebot. As shown in the following figure

Get represents the event, followed by this parameter refers to the spider crawling page, and "/" represents the site's homepage.

220.125.51.130 This IP refers to the search engine spider's server IP address. Of course, this IP address is not necessarily the real search engine spider server address, because there may be someone in order to collect your site content, and impersonating search engine spiders to crawl your site, crawl your content. This is not a big impact, but if the frequency is high, it will consume the resources of the site. So how do we tell? The author gives a small method to himself first. We can open the Control Command window of our computer. Then enter the command for the NSLOOKUP+IP address. If it is true the spider will have its own spider server. We can screen the IP of the fake spider. As shown in the following figure

2: The above we mentioned get parameters followed by the search engine Spider crawling page, we can according to this information analysis search spiders on our site what content more favor, and then to our site content to do the appropriate fine-tuning.

3: We can find through the log spider for our site crawling crawl is based on the weight of the page of the descending graded, General order for the home page, catalog pages and content pages.
