The Apache web server can maintain a log of "referrers" if you ask it to. When a client loads a page, Apache recorded the request in the file /var/www/logs/access_log and, if this is enabled, the referring page is recorded in /var/www/logs/referer_log (that's just how Apache wants to spell it).
Let's say a remote user using a client machine at IP address 1.2.3.4 was reading someone else's page http://somehost.com/. They see a hyperlink pointing to one of your page, http://yourhost.com/somepage.html. Two things are logged on your server when the user clicks on that link:
/var/www/logs/access_log gets a new line, looking something like this:
1.2.3.4 - - [08/Feb/12:01:02:56 -0500] "GET /somepage.html HTTP/1.1" 200 7340
/var/www/logs/referer_log gets a new line, looking something like this:
1.2.3.4 -- http://somehost.com/blah/blah.html -> /somepage.html
Now that's kind of interesting, it shows you the pages on the Internet with static links pointing to your pages. What many people find more interesting is the list of search strings people have entered at Google and other search engines to reach your pages.
We can do this, the referring URL includes the search engine hostname and path to its search page, as well as the search string itself! However, that takes a little massaging before it's easy to read. Here is an example. This is really one line of 241 characters, I have broken it at 80 columns so it fits in your browser:
81.184.32.18 -- http://www.google.es/search?hl=es&client=firefox-a&rls=org.mozil la:es-ES:official&hs=GMa&ei=1KlwSomeMIysjAf8l4SZBQ&sa=X&oi=spell&resnum=0&ct=res ult&cd=1&q=packet+sniffing+tools+for+windows&spell=1 -> /security/monitoring.htm l
Look at that a piece at a time. The client is at IP address 81.184.32.18, which resolves back to a hostname of 81.184.32.18.dyn.user.ono.com. That IP address belongs to an Internet service provider in Aravaca, Spain, according to the whois output:
inetnum: 81.184.0.0 - 81.184.88.255 netname: MENTA-CABLEMODEMS descr: AUNA - CTC descr: Internet de Banda Ampla descr: CableModem country: ES [....] role: Techauna AUNA address: C/ Basauri, 7-9 La Florida, Aravaca address: Aravaca (28023) address: Spain phone: +34911809300
The client did a search from the page http://www.google.es/search, Google's Spanish language search interface. The rest of the referring URL is a collection of variable=value pairs strung together with the ampersand character, &. They specify things like the client's browser, preferred languages, whether Google should do spell checking and the type and number of results desired, and so on. The query itself is specified by q=..., can you find it?
There it is, almost at the end. They asked the Spanish Google page an English query:
packet sniffing tools for windows
Google has made that list of strings into a single string with + characters between the original components. Here it is, highlighted:
81.184.32.18 -- http://www.google.es/search?hl=es&client=firefox-a&rls=org.mozil la:es-ES:official&hs=GMa&ei=1KlwSomeMIysjAf8l4SZBQ&sa=X&oi=spell&resnum=0&ct=res ult&cd=1&q=packet+sniffing+tools+for+windows&spell=1 -> /security/monitoring.htm l
From the list of search results, they clicked on the link to my page about protocol analysis, network monitoring, and packet sniffing. Really, that enormously long Google URL is the search result page itself. The user clicked on something on that dynamically generated search result page that led to my page.
This doesn't look too bad, but there are three things to look out for.
First, not all search engines use q=. Yahoo uses p=. Mywebsearch.com uses searchfor=, which I'm going to remap to q= in an early step.
Second, some searches contain similar variables like aq=... or oq=... when we're expecting q=... on Google. So, we have to be careful about simply saying "Everything after the q= or p= will be the search query." The variable=value pairs don't appear in any predictable order, so we can't look for the first or last instance of q= or p=.
The trick is to notice that the list of variable=value pairs starts after a question mark, ?, and is separated by ampsersands, &. So, the criteria is really: "Everything after either ?q= or &q= or ?p= or &p= will be the search query."
Well, no, not everything after either of those two strings — just everything up to either another ampersand (starting the next variable=value pair) or a blank space (the query happened to be the last one).
Third, the search engine and the client's browser may replace some characters with their ASCII codes. Instead of a literal space character, there will be %20 because the ASCII code for the space character is hexadecimal 0x20. Here's an example with a punctuation mark. The user typed TCP/IP Class handouts and the slash character / was replaced with the ASCII code %2F. That could appear as either %2F or %2f, we have to account for both upper and lower case ASCII codes.
209.136.52.205 -- http://www.google.com/search?hl=en&q=TCP%2FIP+Class+handouts&aq=f&oq=&aqi= -> /tcpip/
What we want to do to each line is:
This is just one big sed command! Instead of a bunch of sed commands piped together, I can just run one with multiple edit strings. I have put it in a file, a one-line shell script:
#!/bin/sh
# Clean up search strings from /var/www/logs/referer_log
sed -e 's/%[01]./ /g' \
-e 's/%20/ /g' \
-e 's/%21/!/g' \

-e 's/^ //'
I have that shell script in a directory in my command search path, ~/bin/script/log-clean as I've organized things. Notice that it ignores any command-line parameters, it simple reads from standard input and writes to standard output. That's because I want to be able to easily use it in various ways:
What are all the searches? Generally speaking, searches contain "=". Google image searches contain "imgurl=" and they aren't as useful for this analysis. % grep "=" /var/www/logs/referer_log | grep -v "imgurl=" | log-clean What about just Google non-image searches? % grep "google" /var/www/logs/referer_log | grep -v images.google | log-clean What about Google vs Yahoo? % grep "google" /var/www/logs/referer_log | grep -v "imgurl=" | log-clean % grep "yahoo" /var/www/logs/referer_log | log-clean
Those work, but they aren't very useful because they simply print the cleaned versions in the order in which they occurred. Here is a much more interesting question that we can now easily answer:
What is the complete list of searches used to find my pages, sorted in order of popularity? I would like to know the search string itself, how many times that was used, and its rank. Oh, and since people are erratic about capitalization, and some people think that Google pays more attention if you SHOUT IN ALL CAPS, I should force the queries to all lower case before doing the analysis. Oh, and I don't want to know about strange things that only happened once or a few times, let's limit this to searches done 10 times or more. Does this sound like a complicated request? This is easy in Unix!
% grep "=" /var/www/logs/referer_log | grep -v "imgurl=" | \
log-clean | \
tr 'A-Z' 'a-z' | sort | uniq -c | sort -nr | awk '$1 > 9' | cat -n
KEY:
log-clean We already know what this does...
tr Replaces upper case with lower case.
sort Reorder the lines into lexicographic order,
grouping identical lines together.
uniq -c Counts sequences of identical lines, replacing
each block with the count and the line content.
sort -nr Reorder the lines into reverse numerical order, numerical
because of the -n and reverse order because of the -r.
awk '$1 > 9' Only output those lines where field #1
is numerically greater than 9.
cat -n Insert line numbers before each line.
Here are the results for a log covering about six weeks. The Internet is a very strange place....
