What is it for?
Rather than performing numerous Google searches and rather than browsing to determine Pagerank, let Perl summarise large chunks of figures in a single text file. This can be done in a cyclic manner by setting up a cron job.
Two Perl scripts are necessary (whether you need both depends on what figures you wish to collect from Google):
This essentially configures the CPAN module, which then enables quick installation of new modules. Once CPAN is set up, simply type in:
Having got the PageRank script (
The file should contain a list of tasks to run. In my case, for instance:
Needless to mention, all files must be available by forming a part of the
UsageThen, by running:
all results should be put in a single text file.
AutomationA cron job such as:
will update the file every night. If you are not familiar with cron jobs, now is a good time to find out. To find out only about differences, i.e. to see changes in terms of numbers, one can do the following:
If the above does not provide sufficient infomation or is too static, follow the steps below. There is a way of keeping track of SERP's, links, and corresponding PageRank. The Perl code is very bandwidth-greedy so it should be use with great restraint.
Detecting Changes in Regular Pages
You can in principle fetch a Web page every night and have changes flagged to you. The approach is similar to the one above, but it relies on
The file named
