DISCLAIMER: I am no legal expert and the information below is solely that which I have gleaned from a rather quick online search. This post is merely a starting point to head you in the right direction. I hope it provides a little help.
The first thing that most people – including me – are probably asking is, what are cookies? The BBC has a fairly easy-to-understand guide. For bloggers, they are most usually used by statistical and analytical programmes to track the number of people coming to your site each day, week, month, etc. Google Analytics relies on cookies for this very purpose and for bloggers – as well as for owners of most websites – this is an essential tool, particularly if you already do – or plan to – monetise your site. Third-party cookies will be a feature on your blog if you have already monetised your blog and carry adverts.
This legislation has its origins in the EU and the directive was in fact implemented just over a year ago, however the ICO gave UK sites a year to put their changes into place. No one really seems to have taken much notice though, until the very last minute.
I have searched high and low for information on how blogs will – or could – be penalised and what level of consent and the only thing I have managed to find if this post over at Brit Mums. However, I have managed to find this rather useful site and which also includes coding and widgets for use on your blog straight away.
UPDATE: Oh, and this post, too, by Jude Wharton – very well written and comprehensive.
