What are server logs?

[kexej28769@nongnue]

A log file is a recording of everything that goes in and out of a server. Think of it as a ledger of requests made by crawlers and real users. You can see exactly what resources Google is crawling on your site.

You can also see which errors need your attention. For cambodia number data , one issue we discovered from our analysis was that our CMS created two URLs for each page and Google discovered both. This led to duplicate content issues because two URLs with the same content were competing with each other.

Analyzing logs isn't rocket science—the logic is the same as when working with tables in Excel or Google Sheets. The hardest part is accessing them—exporting and filtering that data.

It can also be a bit daunting to look at the log file for the first time because when you open it, you see something like this:



Calm down and take a close look at one line:



[08/Dec/2017:04:54:20 -0400] The timestamp is (when)
GET method .
/contact/ The requested URL is (is)
200 The status code is (result).
11179 The bytes transferred are (size)
"-" The referring URL (source) is — it is empty because this request was made by a crawler.
Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)User agent (signature) — This is the user agent of Google Bot (desktop)
Once you know what each line consists of, it's not so scary. It's just a lot of information. But that's where the next step comes in handy.

Tools you can use
There are many tools you can choose from that will help you analyze your log files. I won't give you a complete rundown of the tools available, but it's important to know the difference between static and real-time tools.
