This second, sadly wine-free, instalment of the series on how to fight comment spam (read the first here) is looking into identifying and fighting spammers in a slightly different way. While the method I describe in this posting is not for everyone, the information may still be of interest to you, especially if you want to understand how many visitors your website has, what Google Analytics does, what server logfiles are and how to interpret these numbers through software such as Webalizer or AWStats.
Like most bloggers we are curious to know who is reading our blog. Some of our readers we know through the comments they leave, emails that they send, through Twitter or even personal contacts - which, I hasten to add, makes them more than just 'readers' but partners in a conversation. Even so, as a blogger you also want to know about those who just read your blog and do not directly engage with you – maybe to boost your ego ('Hundred people visit my blog every day.') or because you want to know if you are doing a good job engaging the visitors, i.e.: do they return? do they spend much time on the site? what proportion of your readers leave comments? where are they from?
Basically, there are three ways of finding out about this.
