There were a couple of posts today based on the idea that Google Autocomplete (where it makes suggestions based on what you've typed so far) is a good test of whether a brand is a ...

You may remember that when Google Instant launched (which shows suggestions and results based on what you're typing) that its rude words filter was a bit off - allowing paki jokes and kiddie fiddler but banning lesbian and funbags.

Search Engine Land has pointed out that the Google Images filter is allowing soft-porn suggestions through, such as girls breastfeeding each other.

Google Video has similar problems it would seem.

Google has announced keyboard navigation for Google Instant results - and it's another feature that's likely to hit PPC advertisers in the pocket.

The first result now has a blue arrow next to it, which you can move up and down with your arrow keys. You can then just press enter to go to the result you want. But this means firms with PPC and natural results will find their PPC ad being clicked more.

Google's new Instant functionality (where results start to be displayed as you type, rather than waiting for you to finish typing and press search) has filters in place to stop, for instance, results for "cock" appearing midway through typing Cockfosters.

But Google is filtering words like gay, lesbian and clitoris, putting them in the same bracket as search terms like pre-teen models, rape and nigger. Meanwhile it's allowing results to be shown when you search for coon, necrophilia, kiddie fiddler and female genital mutilation.

Google Instant is rolling out - where it starts serving up results as you type, to save you having to press a few more keys in. You can try it as http://www.google.com/webhp?sclient=psy (yes, psy for psychic).

Start looking for analytics, however, and Google shows up its own pages once you get to "anal". Oo-er missus.
