Google Alert provides users with regular updates on upto three 'search strings' or 'keywords' of their choice. My top three are 'artist illustrator', 'Jonathan Furness' and 'Ultralab'.

Essentially this service performs these three searches and emails you (sometimes daily) with the details of any new webpages containing these keywords. Handy if you are interested in how your website or chosen keywords are being used on the Internet.

Here's an example of what Google Alert can send you.....

Google Alert has new results which can also be browsed interactively:
